Hello everyone,

I was wondering if someone could help me out. I am trying to create a custom AlertDialog. In order to do this, I added the following line of code in styles.xml

@drawable/color_panel_background

  • color_panel_background.9.png is located in drawable folder. This is also available in Android SDK res folder.

The following is the main activity.

package com.customdialog;

import android.app.Activity; import android.app.AlertDialog; import android.app.Dialog; import android.content.DialogInterface; import android.os.Bundle;

public class CustomDialog extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main);

    this.setTheme(R.style.CustomAlertDialog);
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setMessage("HELLO!");
    builder .setCancelable(false)
      .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int id) {
           //MyActivity.this.finish();
       }
   })
   .setNegativeButton("No", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int id) {
           //dialog.cancel();
       }
   });

    AlertDialog alertdialog = builder.create();
    alertdialog.show();
}

}

In order to apply the theme to an AlertDialog, I had to set the theme to the current context.

However, I just can't seem to get the app to show customized AlertDialog. Can anyone help me out with this, and thank you very much in advance!
