Answer 1

试试这个：

alertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { 
       public void onClick(DialogInterface dialog, int which) { 
        dialog.dismiss(); 
       } 
      }); 

      alertDialog.setPositiveButton("Save", new DialogInterface.OnClickListener() { 
       public void onClick(DialogInterface dialog, int which) { 

       } 
      }); 

      alertDialog.show(); 


      //Grab the window of the dialog, and change the width 
      WindowManager.LayoutParams lp = new WindowManager.LayoutParams(); 
      Window window = alertDialog.getWindow(); 
      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); 

    } 
});
