1、1)更改AlertDialog窗口大小的方法:AlertDialog dialog = new AlertDialog.Builder(this).create();dialog.show();WindowManager.LayoutParams params =dialog.getWindow().getAttributes();params.width = 200;params.height = 200 ;dialog.getWindow().setAttributes(params);注意:是先显示出来dialog,show()出来,才能再设置宽高属性
2、2)去除边框AlertDialog.setView(view,0,0,0,0);
