Question

I create a thread to update my data and try to do notifyDataSetChanged at my ListView.

private class ReceiverThread extends Thread {

@Override
public void run() { 
    //up-to-date
    mAdapter.notifyDataSetChanged();
}

The error occurs at line:

mAdapter.notifyDataSetChanged();

Error:

12-29 16:44:39.946: E/AndroidRuntime(9026): android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.

How should I modify it?

Answer 1

Use runOnUiThread() method to execute the UI action from a Non-UI thread.

private class ReceiverThread extends Thread {
@Override
public void run() { 
Activity_name.this.runOnUiThread(new Runnable() {

        @Override
        public void run() {
             mAdapter.notifyDataSetChanged();
        }
    });
}
