Capture whole scrollview bigger than screen [duplicate]

Question

The main issue is saving the whole scroll view as a bitmap image rather than just what appears on the screen. Is there a way to save whole scroll view, and if so how?

Answer 1

Make a RelativeLayout or LinearLayout in your ScrollView to get Bitmap from Layout.

Organize this way:

public class ActivityA extends Activity {

LinearLayout PP_Ll;
Button btn_capture;

@Override
protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);
setContentView(R.layout.main);

PP_Ll = (RelativeLayout) findViewById(R.id.PP_Ll);
Button btn_capture= (Button) findViewById(R.id.btn_capture);

btn_capture.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

        Bitmap bitmap = takeScreenshot();
        saveBitmap(bitmap);

        }
    });

public Bitmap takeScreenshot() {

    View rootView = getWindow().getDecorView().findViewById(R.id.PP_Ll);
    rootView.setDrawingCacheEnabled(true);
    return rootView.getDrawingCache();

}

public void saveBitmap(Bitmap bitmap) {

    String root = Environment.getExternalStorageDirectory().toString();
    File newDir = new File(root + "/Folder");
    newDir.mkdirs();
    Random gen = new Random();
    int n = 10000;
    n = gen.nextInt(n);
    String fotoname = "Photo-" + n + ".jpg";
    File file = new File(newDir, fotoname);
    if (file.exists())
        file.delete();
    try {
        FileOutputStream fos = new FileOutputStream(file);
        bitmap.compress(CompressFormat.JPEG, 100, fos);
        fos.flush();
        fos.close();
        Toast.makeText(getApplicationContext(),
                "Saved in folder: 'Folder'", Toast.LENGTH_SHORT).show();

    } catch (FileNotFoundException e) {
        Log.e("GREC", e.getMessage(), e);
    } catch (IOException e) {
        Log.e("GREC", e.getMessage(), e);
    }

}
}}

Your RelativeLayout will be saved in certain directory as a BitMap. Good luck.

Note: You have to insert your imageviews, textviews etc. into your RelativeLayout in .xml file that all can go into screenshot.
