How to add an icon before each item in alert dialog?

Question

I am using an AlertDialog (see the below code) and would like to put an image before each text.

For example, email icon then text \"Email\", Facebook icon then text

Answer 1

To scale images:

//Put the image on the TextView
int dp50 = (int) (50 * getResources().getDisplayMetrics().density + 0.5f);
Drawable dr = getResources().getDrawable(R...YOUR_DRAWABLE);
Bitmap bitmap = ((BitmapDrawable) dr).getBitmap();
Drawable d = new BitmapDrawable(getResources(), Bitmap.createScaledBitmap(bitmap, dp50, dp50, true));
tv.setCompoundDrawablesWithIntrinsicBounds(d, null, null, null);

// Add margin between image and text (support various screen densities)
int dp10 = (int) (10 * getResources().getDisplayMetrics().density + 0.5f);
tv.setCompoundDrawablePadding(dp10);
