说明:在AlertDialog自定义布局的时候,想要一个圆角效果,但是给xml设置圆角后,AlertDialog并不是显示的圆角,只有自定义的布局是圆角样式,AlertDialog会显示出一个白色四方的背景
AlertDialog alertDialog = new AlertDialog.Builder(this).create();
Window window = alertDialog.getWindow();
//这一句消除白块
window.setBackgroundDrawable(new BitmapDrawable());
//自定义的xml
window.setContentView(R.layout.mydialog);
alertDialog.show();
