How to showPopupWindow after AsyncTask finished?

Issue

I want to display a textView in popup Window when I click a View , but the calculation needs time, so I make the calculation in AsyncTask, but how to show the popup Window immediately after the AsyncTask process is finished?

public void onClick(View widget) {

        MyAsyncTask asyncTask = new MyAsyncTask(new AsyncResponse() {
            @Override
            public void processFinish(Object output) {
            meaning_result = (String) output;
            }
            });
         asyncTask.execute("xxxxx");
         showPopupWindow(widget);
}

This is my first thought but the showPopupWindow(widget) executes first and the meaning_result has not assigned yet. How to make showPopupWindow(widget) runs once the meaning_result is assigned?

Solution

Try something like this :

public void showPopUp(final View widget){
         runOnUiThread(new Runnable() {
            @Override
            public void run() {
                showPopupWindow(widget);
            }
        });
}

and :

public void onClick(final View widget) {

        MyAsyncTask asyncTask = new MyAsyncTask(new AsyncResponse() {
            @Override
            public void processFinish(Object output) {
                meaning_result = (String) output;
                showPopUp(widget);
            }
        });
        asyncTask.execute("xxxxx");

    }

Hope this helps
