Answer 3

Versuchen Sie den folgenden Code, damit wird Ihr Problem gelöst.

//Grab the window of the dialog, and change the width 
    WindowManager.LayoutParams lp = new WindowManager.LayoutParams(); 
    Window window = dialog.getWindow(); 
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT)); 
    lp.copyFrom(window.getAttributes()); 
    //This makes the dialog take up the full width 
    lp.width = WindowManager.LayoutParams.MATCH_PARENT; 
    lp.height = WindowManager.LayoutParams.WRAP_CONTENT; 
    window.setAttributes(lp);
