Android take screen shot programmatically

Solution 1:

Here you go...I used this:

View v = view.getRootView();
v.setDrawingCacheEnabled(true);
Bitmap b = v.getDrawingCache();
String extr = Environment.getExternalStorageDirectory().toString();
File myPath = new File(extr, getString(R.string.free_tiket)+".jpg");
FileOutputStream fos = null;
try {
    fos = new FileOutputStream(myPath);
    b.compress(Bitmap.CompressFormat.JPEG, 100, fos);
    fos.flush();
    fos.close();
    MediaStore.Images.Media.insertImage( getContentResolver(), b, 
                                         "Screen", "screen");
} catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (Exception e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

v iz root layout...just to point ;)))

Solution 2:

For the next reader of this question-

The very simple way to do this by drawing your view to canvas-

pass your main layout reference to this method-

 Bitmap file = save(layout);

 Bitmap save(View v)
   {
    Bitmap b = Bitmap.createBitmap(v.getWidth(), v.getHeight(), Bitmap.Config.ARGB_8888);
    Canvas c = new Canvas(b);
    v.draw(c);
    return b;
   }

Solution 3:

I think you have to wait until the layout is drawn completely..Use ViewTreeObserver to get a call back when layout is drawn completely..

On your onCreate add this code..Only call getScreen from inside onGlobalLayout()..

ViewTreeObserver vto = content.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
  @Override
  public void onGlobalLayout() {
    content.getViewTreeObserver().removeGlobalOnLayoutListener(this);
    getScreen();
  }
});

I asked a somewhat similiar question once..Please see my question which explains the way to take screenshot in android..Hope this helps

Solution 4:

public class MainActivity extends Activity
{
Button btn;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    btn = (Button) findViewById(R.id.btn);
    btn.setOnClickListener(new OnClickListener()
    {

        @Override
        public void onClick(View v)
        {
            // TODO Auto-generated method stub
            Bitmap bitmap = takeScreenshot();
            saveBitmap(bitmap);

        }
    });
}

public Bitmap takeScreenshot()
{
    View rootView = findViewById(android.R.id.content).getRootView();
    rootView.setDrawingCacheEnabled(true);
    return rootView.getDrawingCache();
}

public void saveBitmap(Bitmap bitmap)
{
    File imagePath = new File(Environment.getExternalStorageDirectory() + "/screenshot.png");
    FileOutputStream fos;
    try
    {
        fos = new FileOutputStream(imagePath);
        bitmap.compress(CompressFormat.JPEG, 100, fos);
        fos.flush();
        fos.close();
    }
    catch (FileNotFoundException e)
    {
        Log.e("GREC", e.getMessage(), e);
    }
    catch (IOException e)
    {
        Log.e("GREC", e.getMessage(), e);
    }
}
}

don't forgot to give write external storage permission!
