I have a runnable inside a fragment. The runnable is meant to update the textviews as well as receive input using buttons. But the program does not enter even once inside the runnable.
Please help. What am I doing wrong. Thanks. The code is as follows. I have buttons and textviews inside the runnable.
public class TodayFragment extends Fragment {
//initialisations
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
//UI initialisations
Handler mHandler = new Handler();
Runnable mTicker = new Runnable() {
@Override
public void run() {
//user interface interactions and updates on screen
mHandler.postDelayed(mTicker, 1000);
mTicker.run();
}
it seems you wanna change your views in every 1 second. if you say so you should execute your handler outside your runnable method aswell. ie:
Handler mHandler = new Handler();
Runnable mTicker = new Runnable() {
@Override
public void run() {
// user interface interactions and updates on screen
// if you want to run this handler only once then delete below line
mHandler.postDelayed(mTicker, 1000);
}
};
mHandler.postDelayed(mTicker, 1000);
try this change
mTicker = new Runnable() {
public void run() {
//user interface interactions and updates on screen
mHandler.postDelayed(mTicker, 1000);
}
};
mTicker.run();
It's work for me.
public class TodayFragment extends Fragment {
//initialisations
Runnable mTicker;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final Handler mHandler = new Handler();
mTicker = new Runnable() {
@Override
public void run() {
// user interface interactions and updates on screen
mHandler.postDelayed(mTicker, 1000);
}
};
mHandler.postDelayed(mTicker, 1000);
return inflater.inflate(R.layout.fragment_today, container, false);;
}
