Record Web Start Time

I try Date Class. I create app of "record web start time" to check Date Class.
The app have the time of pushing "Web Start" button.

I get now time.

SimpleDateFormat  sdf = new SimpleDateFormat("yyyy'　/'MM'/'dd'/ 'HH':'mm':'ss':'");  
Date  date = new Date();  

I get previous time of pushing "Web Start" button. I use SharedPreferences Class.

SharedPreferences pref = getSharedPreferences("pref", MODE_WORLD_READABLE|MODE_WORLD_WRITEABLE);
String votetime = pref.getString("votetime", sdf.format(date));

I preview previous time.

TextView prevvotetime = (TextView)findViewById(R.id.text1);
prevvotetime.setText(votetime);

If pushing "Web Start" button, I update time.
set listener.

Button votebutton = (Button)findViewById(R.id.button1);
votebutton.setOnClickListener(new View.OnClickListener() {

 @Override
 public void onClick(View v) {
 }
});

I update time and save time to SharedPreferences .

SimpleDateFormat  sdf = new SimpleDateFormat("yyyy'　/'MM'/'dd'/ 'HH':'mm':'ss':'");  
Date  date = new Date(); 

SharedPreferences pref = getSharedPreferences("pref", MODE_WORLD_READABLE|MODE_WORLD_WRITEABLE);
Editor e = pref.edit();
e.putString("votetime", sdf.format(date));
e.commit();

Web Browser

I try WebView class.

donwload apk.

set setWebViewClient for no intent WEB BROWSER.

WebView w = (WebView)findViewById(R.id.webView1);
w.setWebViewClient(new WebViewClient());

enable javascript.

w.getSettings().setJavaScriptEnabled(true);

add Zoom Control

w.getSettings().setBuiltInZoomControls(true);

If app finish to load web page, call callback. I register callback.

w.setWebViewClient(new webclient());

and callback function by WebViewClient. If call onPageFinish, app update url text and app focus web page.

public class webclient extends WebViewClient {
    @Override
    public void onPageFinished(WebView view, String url) {
        setProgressBarIndeterminateVisibility(false);
        WebView w = (WebView)findViewById(R.id.webView1);
  TextView t = (TextView)findViewById(R.id.editText1);
  String u = w.getUrl();
  t.setText(u);
  w.requestFocus();
    }
    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {
        setProgressBarIndeterminateVisibility(true);
    } 
}

If user push W button, app hide ime.

Button b = (Button)findViewById(R.id.button1);
b.setOnClickListener( new View.OnClickListener() {
 @Override
 public void onClick(View v) {
        EditText e = (EditText)findViewById(R.id.editText1);
        if (e.isFocused()) {
         WebView w = (WebView)findViewById(R.id.webView1);
  mI.hideSoftInputFromWindow(w.getWindowToken(), 0);

If user push W button, app jump url inputted by user.
If input text is not ".", app think text is search word.
If input text is not "http://", app add "http://" to url.

TextView t = (TextView)findViewById(R.id.editText1);
if (!t.getText().toString().matches(".")){
 w.loadUrl("http://www.google.co.jp/search?q=" + t.getText().toString());
} else if (!t.getText().toString().startsWith("http://")) {
 w.loadUrl("http://" + t.getText().toString());
} else {
 w.loadUrl(t.getText().toString());
}

If user input url text, app foucs text all.

EditText e = (EditText)findViewById(R.id.editText1);
e.setOnFocusChangeListener(new View.OnFocusChangeListener() {
 
 @Override
 public void onFocusChange(View v, boolean hasFocus) {
  if (hasFocus == true) {
         EditText e = (EditText)findViewById(R.id.editText1);
   e.selectAll();
  }
 }
});

If user push back button, app go back's web page.

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
 if (keyCode == KeyEvent.KEYCODE_BACK) {
        WebView w = (WebView)findViewById(R.id.webView1);
        w.goBack();
        return true;
    }
    return super.onKeyDown(keyCode, event);

ScaleImage

I did to scale Image on there.
But it is not scale on center, it is to scale on position( 0, 0).

I try to scale on center.

default position is (0. 0).
first, position move center at image

float mx = canvas.getWidth();
float my = canvas.getHeight();
canvas.translate(mx/2, my/2);

second, scale it.

canvas.scale(mScaleFactor, mScaleFactor);

final, take back.

canvas.translate(-(mx/2), -(my/2));

it is cool. source code is here. Please suggest your android issue by twitter or mail, I would try to clear up your issue.

move image

I try to move image in android.
I prepare the image.

int resid = context.getResources().getIdentifier("s066", "drawable", context.getPackageName());
mImage = context.getResources().getDrawable(resid);
mImage.setBounds(0, 0, mImage.getIntrinsicWidth(), mImage.getIntrinsicHeight() );

I prepare GestureDetector for getting onScroll event.

mGestureDetector = new GestureDetector(context, this);

I get touch event.

mGestureDetector.onTouchEvent(ev);

onScroll get moving position and call invalidate() for onDrow.

@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,
  float distanceY) {
 Log.d("book", "distanceX=" + distanceX + "  distanceY=" + distanceY);
 mTranslateX -= distanceX;
 mTranslateY -=distanceY;
 invalidate();
 
 return false;
}

onDrow.

@Override
public void onDraw(Canvas canvas) {
 super.onDraw(canvas);
 
 canvas.save();
 canvas.translate(mTranslateX, mTranslateY);
 mImage.draw(canvas);
 
 canvas.restore();
}

ScaleGestureDetector

I referred this site.

I create custom view.

public class ScaleGestureDetectorView extends View {

I prepare image for Drawable. I prepare s093 named jpeg image.

int resid = context.getResources().getIdentifier("s093", "drawable", context.getPackageName());
Drawable mImage;
mImage = context.getResources().getDrawable(resid);
mImage.setBounds(0, 0, width, height );

I prepare ScaleGestureDetector class.

mScaleGestureDetector = new ScaleGestureDetector(context, mSimpleListener);

call onDraw() by invalidate().

public void onDraw(Canvas canvas) {
 super.onDraw(canvas);
  
 canvas.save();
 canvas.scale(mScaleFactor, mScaleFactor);
 mImage.draw(canvas);
  
 canvas.restore();

input event to ScaleGestureDetector at onTouchEvent.

public boolean onTouchEvent(MotionEvent ev) {
    mScaleGestureDetector.onTouchEvent(ev);
    return true;
}

I prepare ScaleGestureDetector.SimpleOnScaleGestureListener

public void onScaleEnd(ScaleGestureDetector detector) {
 Log.d("ges", "onScaleEnd "+ detector.getScaleFactor());
 mScaleFactor *= detector.getScaleFactor();
 invalidate();
 super.onScaleEnd(detector);
}

OnGestureListener

If you try my sample, you need image and import image at res/drawable-hdpi .

I try onGestureListener interface.
I prepare GestureDetector.

mGestureDetector = new GestureDetector(this, this);

I input onTouchEvent parameter.

public boolean onTouchEvent(MotionEvent ev) {
 mGestureDetector.onTouchEvent(ev);
 return false;
}

I prepare onFling at onGestureListener.

public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {

If velocityY smaller than 0, next page.

if (velocityY < 0) {//right
 mPagenumber++;

If velocityY bigger than 0, prev page.

}else {//left
 mPagenumber--;

select image from Resource. I prepare image name "sxxx.jpg". xxx is number. exsapme s001.jpg, s002.jpg, s003.jpg....s020.jpg...
I set selected image to view.

Resources res = getResources();
int resid = res.getIdentifier(filename, "drawable", getPackageName());
ImageView img = (ImageView)findViewById(R.id.imageView1);
img.setImageResource(resid);

MediaRecoder ParcelFileDescriptor

I try to record camera image in other pc storage.
I use network for transfer data.

I refered this site.

I prepared ParcelFileDescriptor and socket.

ParcelFileDescriptor pfd = null;
Socket  socket = null;

I set for network setting.
192.168.1.2 is my pc ip address.

String hostname = "192.168.1.2";
int port = 5000;

I try to create socket

try {
 socket = new Socket(InetAddress.getByName(hostname), port);
 pfd = ParcelFileDescriptor.fromSocket(socket);
 
} catch (UnknownHostException e1) {
 // TODO Auto-generated catch block
 e1.printStackTrace();
} catch (IOException e1) {
 // TODO Auto-generated catch block
 e1.printStackTrace();
}

I try to set ParcelFileDescriptor to MediaRecorder.

_mediarecorder = new MediaRecorder();
_mediarecorder.setOutputFile(pfd.getFileDescriptor());

Android source code is here.
Next Server side program. this program do in my pc(192.168.1.2).
and this is java language.
I create server socket. port number need to be same between client and server.

ServerSocket svsock = new ServerSocket(5000);

I prepare file.

outFile = new FileWriter("xyz" + i + ".mp4");

I wait client(Android) connecting by acccept.

Socket sock = svsock.accept();

If client(Android) connected, I use accept socket sock.

sock.getInputStream()

I prepare BufferedReader and BufferedWriter, and I write received data to the file.

BufferedReader in = new BufferedReader(new InputStreamReader(sock.getInputStream()));
BufferedWriter wt = new BufferedWriter(outFile);
while(sock.isConnected()) {
 int line = in.read();
 if (line == -1) {
  break;
 }
 wt.write(line);
}

If client(Android) connecting finished, I close.

outFile.close();
sock.close();

server sid source code is here.
IMPORTANT, First server side do, Next Client(Android) do.

server side recive file analysis.

Please suggest your android issue by twitter or mail, I would try to clear up your issue.

client Socket

I send data by socket.
I get socket.

Socket sk = null;
sk = new Socket(addr, 5000);

I prepare BufferedWriter for getOutputStream().

BufferedWriter wBuffer = null;
wBuffer = new BufferedWriter(new OutputStreamWriter(sk.getOutputStream()));

data write and flush and close for sending.

wBuffer.write("testtesttest");
Log.d("socket", "write");
wBuffer.flush();
Log.d("socket", "flush");
wBuffer.close();

I got message "testtesttest" at server side.

Call

I try intent for call the number.
I prepare button for call. and prepare listener.
I intent ACTION_CALL.

Button b= (Button)findViewById(id.button1);
b.setOnClickListener(new View.OnClickListener() {
 
 @Override
 public void onClick(View v) {
        Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:117"));
        startActivity(intent);
 }
});

If you pushed button, phone call 117. 117 is "you get time in japan".

Zoom

i try Camera Zoom.
first, i check to suppert Zoom.

Camera.Parameters param = camera.getParameters();
Log.d("camera", "isZoomSupported = " + param.isZoomSupported ());

and i check to support smooth zoom. my nexusOne is not supported.

Camera.Parameters param = camera.getParameters();
Log.d("camera", "isSmoothZoomSupported = " + param.isSmoothZoomSupported ());

i view list of zoom size.

Camera.Parameters param = camera.getParameters();
List ZoomRatislist = param.getZoomRatios ();
for (int i=0;i < ZoomRatislist.size();i++) {
 Log.d("camera", "list " + i + " = " + ZoomRatislist.get(i));
}

it is list of nexusone zoom. passible is between 0 and 12, from x1 to x2.

0 = 100
1 = 104
2 = 112
3 = 117

SpeechRecognizer

I check SpeechRecognizer class. This class is Speech Recognizing class.
How to get instance is call createSpeechRecognizer(Context);

SpeechRecognizer sr = SpeechRecognizer.createSpeechRecognizer(getApplicationContext());

and make listener class,

class MyRecognitionListener implements RecognitionListener {

 @Override
 public void onBeginningOfSpeech() {
  Log.d("Speech", "onBeginningOfSpeech");
 }

 @Override
 public void onBufferReceived(byte[] buffer) {
  Log.d("Speech", "onBufferReceived");
 }

 @Override
 public void onEndOfSpeech() {
  Log.d("Speech", "onEndOfSpeech");
 }

 @Override
 public void onError(int error) {
  Log.d("Speech", "onError");
 }

 @Override
 public void onEvent(int eventType, Bundle params) {
  Log.d("Speech", "onEvent");
 }

 @Override
 public void onPartialResults(Bundle partialResults) {
  Log.d("Speech", "onPartialResults");
 }

 @Override
 public void onReadyForSpeech(Bundle params) {
  Log.d("Speech", "onReadyForSpeech");
 }
 

 @Override
 public void onResults(Bundle results) {
  Log.d("Speech", "onResults");
  ArrayList strlist = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
  for (int i = 0; i < strlist.size();i++ ) {
   Log.d("Speech", "result=" + strlist.get(i));
  }
 }

 @Override
 public void onRmsChanged(float rmsdB) {
  Log.d("Speech", "onRmsChanged");
 }
 
}

the important method is onResults. There is recognized word in "results".

public void onResults(Bundle results) {
 Log.d("Speech", "onResults");
 ArrayList strlist = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
 for (int i = 0; i < strlist.size();i++ ) {
  Log.d("Speech", "result=" + strlist.get(i));
 }
}

I make the listener.

MyRecognitionListener listener = new MyRecognitionListener();

I set listener.

sr.setRecognitionListener(listener);

I start speech recognizing.

sr.startListening(RecognizerIntent.getVoiceDetailsIntent(getApplicationContext()));

onResults() call only once.
I said "english".
logcat printed.

result=リング
result=english
result=ring
result=イング
result=ing

HttpClient

I use HttpClient Class. I would like to get yahoo's Web Page.
I create DefaultHttpClient Class and set url, create Http Get Message.

String url = "http://www.yahoo.co.jp";
HttpClient hc = new DefaultHttpClient();
HttpGet get = new HttpGet(url);

I do http Get execute. and receive http response.

HttpResponse res;
res = hc.execute(get);

If response is 200 OK, I get http content.

if (res.getStatusLine().getStatusCode() == 200) {
 //It is ok.
 InputStream input = res.getEntity().getContent();

I print http content by LogCat.

BufferedReader rBuffer = new BufferedReader(new InputStreamReader(input, "UTF-8"));
String readLine;

socket

I used Socket Class. I get my blog by Socket Class.

Create Socket.

String host ="playandworkandroid.blogspot.com"; 
sk = new Socket(host, 80);

I prepare for send data and receive data.

rBuffer = new BufferedReader(new InputStreamReader(sk.getInputStream()));
wBuffer = new BufferedWriter(new OutputStreamWriter(sk.getOutputStream()));

I make http Get messeage . and Send it!

wBuffer.write("GET / HTTP/1.1\n");
wBuffer.write("host : " + host + "\n");
wBuffer.write("\n");
wBuffer.flush();

If it receive data, print console.

while((readLine = rBuffer.readLine()) != null) {
 Log.d("HttpGetActivity", readLine);
}

I got my blog page.

ActivityInstrumentationTestCase2 GridView ClickItem

I think must be selected whether onClickItemListener API or onClickListener() API.
First, Test Target Activity...
Reference Basic GirdView Program to here.

Add OnItemClickListener() include GridView. It is selected position information.
OnItemClickListener Class.

mGridView.setOnItemClickListener(new OnItemClickListener() {

 @Override
 public void onItemClick(AdapterView arg0, View arg1, int position,
   long id) {
  Log.d("GridViewActivity", "onItemClick " + position + " " + id);
  
 }
 
});

Second, Tester. It is extends ActivityInstrumentationTestCase2. I call performItemClick with GridView and postion. must be UIThread

mActivity.runOnUiThread(new Runnable() {
 public void run() {
  
  Log.d("GridViewActivity", "performItemClick 3");
  gridview.performItemClick(gridview, 3, 0);
  
  
 }
});
mInstrumentation.waitForIdleSync();

Check Logcat.

performItemClick 3
onItemClick 3 0

It is OK.

ActivityInstrumentationTestCase2 GridView Select View

First, Test Target Activity...
Reference Basic GirdView Program to here.

Add OnClikcListener() include GridView. It is include position information. I create other
OnClickListener Class.

class OnClickListenerDetectPosition implements OnClickListener {
 private int mPosition = 0;
 public OnClickListenerDetectPosition(int position ) {
  mPosition = position;
 }
 @Override
 public void onClick(View v) {
  Log.d("GridViewActivity", "onClick = " + mPosition);
 }
 
}

register OnClickListner by it.

OnClickListener onclikclistener = new OnClickListenerDetectPosition(position);
imageView.setOnClickListener(onclikclistener);

Second, Tester. It is extends ActivityInstrumentationTestCase2. set position. must be UIThread

mActivity.runOnUiThread(new Runnable() {
 public void run() {
  Log.d("GridViewActivity", "setSelection 2");
  gridview.setSelection(2);
 }
});
mInstrumentation.waitForIdleSync();

get selected view and click view.

mActivity.runOnUiThread(new Runnable() {
 public void run() {
  
  Log.d("GridViewActivity", "getSelectedItemPosition = " + gridview.getSelectedItemPosition ());
  
  Log.d("GridViewActivity", "getSelectedView");
  ImageView imageview = (ImageView)gridview.getSelectedView();
  Log.d("GridViewActivity", "performClick");
  imageview.performClick();
 }
});

Check Logcat.

setSelection 2
getSelectedItemPosition = 2
onClick = 2

It is OK.
