Race Condition With Ui Thread Issue.

This is the code i am working on. Here I cant update the UI until myOnResponse is finished.Because we are doing a doInBackgrnd, so my textresponse is empty. And Since onPostExecute

Solution 1:

I don't think that you have to use AsyncTask.

You can do something like this :

YourTask.java

publicclassYourTaskimplementsRunnable {

    privateHandler handler;
    privateTextView textView;

    publicYourTask(TextView textView){
          this.textView = textView;
          handler = newHandler();
    }

    @Overridepublicvoidrun() {
        MessageRequest newMessage = newMessageRequest.Builder().inputText(params[0]).context(context).build();

        GLS_service.message("xxxxxxxxx", newMessage).enqueue(newServiceCallback<MessageResponse>() {

            @OverridepublicvoidonResponse(MessageResponse response) {
                final String textResponse = response.getText().get(0);
                handler.post(newRunnable() {
                             @Overridepublicvoidrun() {
                                   if(textView != null){
                                      textView.setText(textResponse);
                                   }
                             }
                });
            }

            @OverridepublicvoidonFailure(Exception e) {
            }
        });    
    }

}

And now how to use it :

SomeActivity.java

...
textView = (TextView) findViewById(R.id.textView);
...

Thread thread = new Thread(new YourTask(textView));
thread.start();
...

Nevertheless if you want to do this action in Asynktask just try this

privateclassConversationTaskextendsAsyncTask<String, Void, Void> {

    privateHandler handler;

    publicConversationTask(){
           handler = newHandler();
    }

    @OverrideprotectedVoiddoInBackground(String... params) {
        MessageRequest newMessage = newMessageRequest.Builder().inputText(params[0]).context(context).build();

        GLS_service.message("xxxxxxxxx", newMessage).enqueue(newServiceCallback<MessageResponse>() {
            @OverridepublicvoidonResponse(MessageResponse response) {
                final String textResponse = response.getText().get(0);
                handler.post(newRunnable() {
                         @Overridepublicvoidrun() {
                               if(reply != null){
                                  reply.setText(textResponse);
                               }
                         }
                });                 
            }
            @OverridepublicvoidonFailure(Exception e) {
            }
        });
        returnnull;
    }
}

Hope it helps
