Android ListView is not selecting rows

I am trying to use a ListView and I want to select each row to launch different activities, but the method OnItemSelectedItem is not working inside and outside of the OnCreate.

Could someone help me?

use click inside adapter. something like cause i don't know your adapter class i paste from my codes.
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
convertView = mInflater.inflate(R.layout.item_card_list, null);
}
convertView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
}
});
convertView.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View view) {
return true;
}
});
return convertView;
}

TL;DR my gut response would be overlapping Listeners (I count 6 separate Listener calls in one Activity). Put Log.e events in each listener, click what you want to click and see what Log.e fires. You'll know what Listener is being called (in other words, which Listener is eating up you click events).
If none are fired that you most likely haven't implemented your Listener correctly.

It would be good if you create custom adapter.

onBackPressed() unfortunately app has stopped in android phone

I am developing an eCommerce application where most of the java class file using Async Task for fetching data from server and I am using fragment in all java class . My problem is that when I click OnBackPressed it shows error in Async Task line because it takes some time interval again to fetch data from server..

Now in your Fragment:

Also in doInBackground notify the AsyncTask to cancel execution
#Override

parseJSONData();
if (isCancelled()) break;

navigation drawer not working after asynctask

I am using navigation drawer with asynctask in one of the fragments. As soon as I click the element in navigation drawer to start that fragment, my navigation drawer stops working even after the asynctask is finished. I am able to click on navigation drawer and open it , but whenever I click on some other item in navigation drawer, it just closes without loading that fragment associated with that item in nav drawer.

Once again, nothing fancy here. still cant figure out what is making the navigation drawer to just close and not start the fragment, if it is clicked on item to start another fragment.
Thanks.

I guess it will be the Home.bar covers your fragment? Maybe you should use ProgressBar.show() or ProgressBar.dismiss() to control the visibility of the progressbar

performItemClick on item in Android Navigation Drawer not working

I have a sliding drawer, and in the drawer is a ListView with 4 items. I would like to use performItemClick to programmatically click one of the items in the drawer, but no matter what I try the code seemingly does nothing. When the item is clicked it's supposed to replace the fragment currently in view with another fragment, and change the action bar title. But none of those things happen with I run performItemClick.
Here is the performItemClick, in a BroadcastReceiver which is receiving a Broadcast
private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
mDrawerList.performItemClick(mDrawerList.getAdapter().getView(1, null, null),1,mDrawerList.getAdapter().getItemId(1));
Log.d("receiver", "Got message + item clicked");
}
};
And here is the code for the actual activity which contains the performItemClick and the drawer itself, along with the drawers fragments (the performItemClick is near the bottom).

What I have done is something like this inside my Expandable listview adapter for Drawer..
View.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
switch (groupPosition)
{
case 0:
switch (childPosition)
{
case 0:
if (groupPosition == 0 && childPosition == 0)
{ some code }
Edit: this switch starts different activity (or change view if fragment) on each respective item click.. in your case their will be fragments..
