Using toast with pictures on Android 11, toast.getView () is null. After checking, the API has banned some methods in Android 11.

The solution is as follows:

    public static void showCenter(Context context, String text) {
        Toast toast = Toast.makeText (context, text, Toast.LENGTH_ Short);
// in the upper left corner. If you want to move to the right, set the second parameter to & gt; 0; move down and increase the third parameter; the last two parameters only have pixels
if（ Build.VERSION.SDK_ INT < Build.VERSION_ CODES.R) {
            toast.setGravity ( Gravity.CENTER , 0, 0);
            LinearLayout layout = (LinearLayout) toast.getView ();
            ImageView image = new ImageView(context);
            image.setImageResource (R. mipmap.icon_ success);
            layout.addView (image, 0);
        }
        toast.show ();
    }
