问如何在Android中创建自定义警报对话框？

public void selfDestruct(View view) {
         // Kabloey
         Log.d("Naveen", "Test====");
         System.out.println("----------------------ghfgjhf-----------------");
         AlertDialog alertDialog = new AlertDialog.Builder(SecondActivity.this).create();
         alertDialog.setTitle("Reset...");
         alertDialog.setMessage("R u sure?");
         alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
              public void onClick(DialogInterface dialog, int which) {

               //here you can add functions

            } });
         alertDialog.show();
     }

   <Button
     android:layout_height="wrap_content"
     android:layout_width="wrap_content"
     android:text="@string/self_destruct"
     android:onClick="selfDestruct" />
