845 PointsCodes for Refresh button goes wrong!
So, i was able to add a button to the main list menu, but i face difficulties when i try to figure out what codes should be added but the refresh button is clicked. here is what i wrote.
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main_list, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int itemId = item.getItemId();
if (itemId== R.id.action_refresh) {
Intent intent2 = new Intent(this, GetBlogPostsTask.class);
startActivity(intent2);
}
return super.onOptionsItemSelected(item);
}
However, when i press the refresh button. The app quit.
thank you very much!

845 PointsOMG, it so simple! the answer has always been there! here is the solution:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int itemId = item.getItemId();
if (itemId== R.id.action_refresh) {
mProgressBar.setVisibility(View.VISIBLE);
GetBlogPostsTask r_getBlogPostsTask = new GetBlogPostsTask();
r_getBlogPostsTask.execute();
}
return super.onOptionsItemSelected(item);
}
