Taking android screen shot of whole screen

My application has a list view in relative layout. Now I need to take a screen shot of the entire layout including all the content available in the list view and also other contents like button and text view showing in the layout. But my code takes only the visible part of the screen. Here the view is parent layout.

public void screen(){

     View v1 = findViewById(R.id.screenRoot);

    rel.layout(0, 0, rel.getMeasuredWidth(),rel.getMeasuredHeight());    
    View v = v1.getRootView();
    v.setDrawingCacheEnabled(true);

   /* v.measure(MeasureSpec.makeMeasureSpec(w, w), 
            MeasureSpec.makeMeasureSpec(h, h));*/


//        v.layout(0, 0, rel.getWidth(), rel.getHeight());
    v.buildDrawingCache(true);

    System.out.println("rel "+rel.getHeight()+" "+v.getHeight());
    Bitmap b = v.getDrawingCache();  
    v.setDrawingCacheEnabled(false);
    String extr = Environment.getExternalStorageDirectory().toString();
    File myPath = new File(extr, "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");
        System.out.println("my path "+myPath+" "+fos);
    }catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    Toast.makeText(getApplicationContext(), "Image Captured Successfully", 0).show();

}

Call getBitmapFromView from your Click event or any thing. R.id.root is my main RelativeLayout So you can pass you main layout.

LayoutInflater inflater = (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
RelativeLayout root = (RelativeLayout)inflater.inflate(R.layout.youlayourfile,null);
root.setDrawingCacheEnabled(true);

Bitmap bmp = getBitmapFromView(this.getWindow().getDecorView().findViewById(R.id.root).getRootView());

URI uri = storPrintFile(bmp);

This function returns the Bitmap of your layout. Now you just need to store the bitmap into your device and anywhere else.

public Bitmap getBitmapFromView(View v) {
    v.setLayoutParams(new LayoutParams(
            RelativeLayout.LayoutParams.WRAP_CONTENT,
            RelativeLayout.LayoutParams.WRAP_CONTENT));
    v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
            MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
    v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());
    Bitmap b = Bitmap.createBitmap(v.getMeasuredWidth(),
            v.getMeasuredHeight(), Bitmap.Config.RGB_565);

    Canvas c = new Canvas(b);
    v.draw(c);
    return b;       
}

Storing bitmap into device.

public URI storPrintFile(Bitmap bitmapToStore){
    ContextWrapper cw = new ContextWrapper(getApplicationContext());
    String path = cw.getDir("CapturedImages",Context.MODE_PRIVATE).getPath();
    File file = new File(path);
    boolean isFileCreated = false;
    if (!file.exists()) {
        isFileCreated = file.mkdir();
        System.out.println("Directory created in Internal Storage is :" + path);
    }
    String current = "Screen.jpg";//uniqueId.replace(" ", "-").replace(":", "-") + ".jpeg";
    System.out.println("Internal Storage path is : " + current);
    File mypath = new File(file, current);
    try {
        FileOutputStream out = new FileOutputStream(mypath);
        bitmapToStore.compress(Bitmap.CompressFormat.JPEG, 100, out);
        out.flush();
        out.close();

    } catch (Exception e) {
        e.printStackTrace();
    }
    return mypath.toURI();
}
