runOnUiThread(new Runnable(){}) is undefined for the type new Thread(){}

Question

Looking at the part:

runOnUiThread(new Runnable() {

I have the problem:

The method runOnUiThread(new Runnable(){}) is undef         


        

Answer 1

If you are using Fragments just add getActivity()

Here replace :
runOnUiThread(new Runnable() {
By
getActivity().runOnUiThread(new Runnable() {

Answer 2

You have to setOnClickListener that you haven't set in your code like

Button confirm = (Button) dialog.findViewById(R.id.btn_confirm);
confirm.setOnClickListener(new OnClickListener() 
{

    @Override
    public void onClick(View v)
    {
        your call to method...
    }
});

Answer 3

Write like this-

((Activity) context).runOnUiThread(new Runnable() {
    @Override
    public void run() {
        //Code for the UiThread
    }
});

---

For Fragment :

getActivity().runOnUiThread(new Runnable() {
    @Override
    public void run() {
        //Code for the UiThread
    }
});

This may help you.
