ProgressDialog的简单使用

Android中最简单的转圈圈:

ProgressDialog mProgressDialog = new ProgressDialog(Context);

mProgressDialog.setTitle("标题");
mProgressDialog.setMessage("正在加载XXXX信息。。。");
mProgressDialog.setIcon(R.drawable.ic_launcher);// 默认图片
mProgressDialog.setCancelable(false);
mProgressDialog.show();// 显示等待框
// 判断等待框是否正在显示
if (mProgressDialog.isShowing()) {
mProgressDialog.dismiss();// 关闭等待框
}
