You need to use transparent flag for your dialog. But probably you gonna need to create your custom dialog for it:

Dialog mDialog = new Dialog(mContext, android.R.style.Theme_Translucent);

Custom dialog: android dialog transparent

AlertBox: Set Transparent Window in AlertDialog box

  • R.style.Theme_Translucent_NoTitleBar_Fullscreen is not working with my custom dialog box.... – user1227605 May 15 '12 at 10:48
  • public CustomizeDialog(Context context) { super(context); mContext = context; /** 'Window.FEATURE_NO_TITLE' - Used to hide the mTitle */ requestWindowFeature(android.R.style.Theme_Translucent_NoTitleBar_Fullscreen); // requestWindowFeature(Window.FEATURE_NO_TITLE); /** Design the dialog in main.xml file */ setContentView(R.layout.customdialog); v = getWindow().getDecorView(); v.setBackgroundResource(android.R.color.transparent); – user1227605 May 15 '12 at 11:00

  • public class CustomizeDialog extends Dialog implements OnClickListener { @Override public void onWindowAttributesChanged(LayoutParams params) { super.onWindowAttributesChanged(params);} ContextmContext; public CustomizeDialog(Context context) { super(context); mContext =context;requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.customdialog); v = getWindow().getDecorView(); v.setBackgroundResource(android.R.color.transparent);} – user1227605 May 15 '12 at 11:17

Try this: 

 public class CustomDialog extends Dialog implements OnClickListener {      
  Button button_home,button_cancel,button_resume;     
    public GamePauseMenu(Context context) {          
      super(context,R.style.Theme_Transparent);      
      }     


    public void show(int bg) {              
             super.show();         
           setContentView(R.layout.custdialog);       
            button_resume = (Button)findViewById(R.id.imageButton1);                  button_resume.setOnClickListener(this);    
     }     public void onClick(View v) {         cancel();      }   }

                                // Write your code here to execute after dialog
