Accessing UI thread handler from a service

Question

I am trying some thing new on Android for which I need to access the handler of the UI thread.

I know the following:

1. The UI thread has its own handler

Answer 1

You can get values through broadcast receiver......as follows, First create your own IntentFilter as,

Intent intentFilter=new IntentFilter();
intentFilter.addAction("YOUR_INTENT_FILTER");

Then create inner class BroadcastReceiver as,

    private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
    /** Receives the broadcast that has been fired */
    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent.getAction()=="YOUR_INTENT_FILTER"){
           //HERE YOU WILL GET VALUES FROM BROADCAST THROUGH INTENT EDIT YOUR TEXTVIEW///////////
           String receivedValue=intent.getStringExtra("KEY");
        }
    }
};

Now Register your Broadcast receiver in onResume() as,

registerReceiver(broadcastReceiver, intentFilter);

And finally Unregister BroadcastReceiver in onDestroy() as,

unregisterReceiver(broadcastReceiver);

Now the most important part...You need to fire the broadcast from wherever you need to send values..... so do as,

Intent i=new Intent();
i.setAction("YOUR_INTENT_FILTER");
i.putExtra("KEY", "YOUR_VALUE");
sendBroadcast(i);
