I need to set the images to grid view dynamically. but i'm getting exception: android.widget.LinearLayout cannot be cast to android.widget.ImageView I need to get the view of the grid without onclick. So please help me.
private void setTickMark(String icon_name_val) {
ImageView imageView = (ImageView) rootView;
//getting clicked image
String iconimg = icon_name_val;
String iconimgname = iconimg;
// int idval = getResources().getIdentifier(iconimgname, "drawable",getActivity().getPackageName());
// Drawable drawable = getResources().getDrawable(idval);
// Log.d("dra",String.valueOf(drawable));
int resID = getResources().getIdentifier(iconimgname, "drawable", getActivity().getPackageName());
Bitmap bitmapbus = BitmapFactory.decodeResource(getResources(), R.drawable.bus);
Bitmap bitmap1 = BitmapFactory.decodeResource(getResources(), resID);
Bitmap resized = Bitmap.createScaledBitmap(bitmap1, bitmapbus.getWidth(), bitmapbus.getHeight(), true);
Bitmap bitmap2 = BitmapFactory.decodeResource(getResources(), R.drawable.tick);
// Bitmap resultBitmap = Bitmap.createBitmap(bitmap2.getWidth(), bitmap2.getHeight(), Bitmap.Config.ARGB_8888);
Bitmap resultBitmap = Bitmap.createBitmap(bitmapbus.getWidth(), bitmapbus.getHeight(), Bitmap.Config.ARGB_8888);
Canvas c = new Canvas(resultBitmap);
c.drawBitmap(resized, 0, 0, null);
c.drawBitmap(bitmap2, 0, 0, null);
imageView.setImageBitmap(resultBitmap);
