How to set Icon to the Alert Dialog Programatically in Android

Em using these statements for creating an Alert Dialog and set icon to it,

AlertDialog.Builder builder = new AlertDialog.Builder(this);

builder.setIcon(this.getDrawable(R.drawable.video_downloader));

builder.setTitle("Congratulations !!!");

builder.show();


But it is crashing at setIcon, when I checked in drawable folder, the video_downloader icon is there already.

Use this

builder.setIcon(ContextCompat.getDrawable(MyActivity.this,R.drawable.video_downloader));


instead of this

builder.setIcon(this.getDrawable(R.drawable.video_downloader));


FYI

getDrawable() method was deprecated in API level 22.

getDrawable()

try this,

AlertDialog.Builder builder = new AlertDialog.Builder(this);

builder.setIcon(getResources().getDrawable(R.drawable.video_downloader));

builder.setTitle("Congratulations !!!");

builder.show();


your error occured here builder.setIcon(this.getDrawable(R.drawable.video_downloader));

builder.setIcon(this.getDrawable(R.drawable.video_downloader));

just try this

// Setting Icon to Dialog
alertDialog.setIcon(R.drawable.video_downloader);
