在Android中创建线程内的处理程序

Question

I tried to show the toast from the thread.

Toast.makeText(activity.getApplicationContext(), "This is the Toast message", Toast.LENGTH_LONG).show();

but throws the exception

java.lang.RuntimeException:Can't create a handler inside thread that has not called Looper.prepare().

How do I solve this problem? I have put the Looper.myLooper().prepare(); before the Toast.makeText(....).show();

When I have done this it doesn't throw the exception but does not show any toast message.

So how do I solve this problem?

Thanks in advance.

You can create your Toast message in onPostExecute of Async Task.. Try this..

protected void onPostExecute(Void result) {
  Toast.makeText(ActivityName.this,"Your Text", Toast.LENGTH_SHORT).show(); 
  if (this.dialog.isShowing()) {
    this.dialog.dismiss();
  }
}
