try this to convert a view (framelayout) into a bitmap:

public Bitmap viewToBitmap(View view) {
    Bitmap bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    view.draw(canvas);
    return bitmap;
}

then, save your bitmap into a file:

try {
        FileOutputStream output = new FileOutputStream(Environment.getExternalStorageDirectory() + "/path/to/file.png");
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, output);
        output.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

don't forget to set the permission of writing storage into your AndroidManifest.xml:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

try this...

public static void saveFrameLayout(FrameLayout frameLayout, String path) {
    frameLayout.setDrawingCacheEnabled(true);
    frameLayout.buildDrawingCache();
    Bitmap cache = frameLayout.getDrawingCache();
    try {
        FileOutputStream fileOutputStream = new FileOutputStream(path);
        cache.compress(Bitmap.CompressFormat.PNG, 100, fileOutputStream);
        fileOutputStream.flush();
        fileOutputStream.close();
    } catch (Exception e) {
        // TODO: handle exception
    } finally {
        frameLayout.destroyDrawingCache();
    }
}
