ProgressDialog 仅在 setContentView() 之后触发
我有一个 ProgressDialog:
ProgressDialog pDialog = ProgressDialog.show(MyActivity.this, "", "Logging In...");
它应该从方法的顶部运行直到到达结束。以下是授权成功时执行的块：
if(writeSuccess){
Toast.makeText(getApplicationContext(), "Login Success!", Toast.LENGTH_SHORT).show();
pDialog.dismiss();
setContentView(R.layout.auth);
}
但是 ProgressDialog 不会触发。但是，如果我注释掉它，它将在 ContentView 切换后触发。有人对这个问题有什么想法或解决办法吗？
I have a ProgressDialog:
ProgressDialog pDialog = ProgressDialog.show(MyActivity.this, "", "Logging In...");
And it is supposed to run from the top of the method and through until it reaches an end. Here is the block that is execute on authorization success:
if(writeSuccess){
Toast.makeText(getApplicationContext(), "Login Success!", Toast.LENGTH_SHORT).show();
pDialog.dismiss();
setContentView(R.layout.auth);
}
But the ProgressDialog will not fire. But if I comment out it's dismissal it will fire after the ContentView has been switched. Anybody have any idea or remedy to this problem?

使用 ASyncTask 来做你想做的事情。在 onPreExecute 上，创建并显示对话框，在 doInBackground 上进行登录，在 onPostExecute 上关闭先前创建的对话框。
Use an ASyncTask to do what you want. On onPreExecute, create and display the dialog, on doInBackground, make your Login, and on onPostExecute dismiss the dialog previously created.
