Custom Listview onClick not moving to Tab Fragments page

Custom Listview onClick not moving to Tab Fragments page - android

I have an activity with CustomAdapter ListView and TabLayout with three tabs TrainerTab1, TrainerTab2, TrainerTab3. While clicking on an item it should move to next page that is to TrainerTab1 Fragment.
I need to pass the id from ListView onClick() to fragment page. I have used Bundle to pass value but the items are not working. When I click on an item it's not responding and not showing any error.
My custom ListView Class is:
public class Trainer extends AppCompatActivity {
String tabUrl = "http://adoxsolutions.in/numuww/services/trainers";
private GridView gridView;
ArrayList<HashMap<String, String>> alist = new ArrayList<>();

StrictMode.setThreadPolicy(policy);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
new Train().execute();
}
private class Train extends AsyncTask<Void, Void, Void> {
protected void onPreExecute() {
mprogress = new ProgressDialog(Trainer.this);
mprogress.setMessage("Loading...");
mprogress.setIndeterminate(false);
mprogress.show();
}
#Override

try {
URL url = new URL(tabUrl);
HttpURLConnection connect = (HttpURLConnection) url.openConnection();
connect.setRequestMethod("POST");
//

InputStream in = new BufferedInputStream(connect.getInputStream());
String response = org.apache.commons.io.IOUtils.toString(in, "UTF-8");
System.out.println(response);
Log.d("VALUE:", response);
JSONObject obj = new JSONObject(response);
JSONArray jsArray = obj.optJSONArray("Trainers");
for (int k = 0; k < jsArray.length(); k++) {
HashMap<String, String> map = new HashMap<String, String>();
obj = jsArray.getJSONObject(k);

Inside the onClickListener
after adding the bundle to the fragment.
FragmentManager fragmentManager = Trainer.this.getSupportFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.add(R.id.someIDForYourFrameLayout, tt1).commit();

can you just ellaborate where to use this exactly. I mean I don't understand how to add id of fragment to transaction.add(R.id.someIDForYourFrameLayout, tt1).commit();
I tried like this:
Bundle h=new Bundle();
h.putString("id",MyArr.get(position).get("id"));
Fragment tt1=new TrainerTab1();
tt1.setArguments(h);
FragmentTransaction transact=getSupportFragmentManager().beginTransaction();
transact.add(R.id.trainerFragment,tt1).commit();

Add this
adapter.notifyDataSetChanged() in postExecute

I think you are forgetting to notify adapter about data change after you are getting data.
Declare your Adapter Global so you can call it from any where
DailyDataAdapter adapter = null;
and initialize it like this in your onCreateView
adapter = new DailyDataAdapter(getActivity(), data_list);
so call this notifyDataSetChanged() after doInBackground in your onPostExecute
#Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
adapter.notifyDataSetChanged();
}
this should work for you.

For that you have to use Image Loader to load image.
Refer below link for that.

Control CheckBox status

I have retrieved data from a remote db using json and i have created a custom listView with this data. I have three TextView and one CheckBox and it works perfectly. So, i have added a button that would control selected items in list and eventually transfer selected item in another activity. Problem was solved as suggested,but if i scroll list, selected items losts status.I think it depends from horder or adapter. Can someone help me? Here is my code

when user select a check box, put its corresponding data to a list.and send the list in bundle on button click.and receive it on another activity with the key.
you need to create a list like.
ArrayList<HashMap<String, String>> list_selected;
public ListatoAdapter(Context context, ArrayList<HashMap<String, String>> list_serv) {
super();
this.context = context;
this.dataList = list_serv;
list_selected = new ArrayList<HashMap<String, String>>();
}
change the listener as.
holder.Ceck.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
HashMap<String,String> data = dataList.get(position);
if(isChecked){
addToSelected(data);
}else{
removeSelected(data);
}
}
});
private void addToSelected(HashMap contact){
if(!list_selected.contains(contact))list_selected.add(contact);
}
private boolean removeSelected(HashMap contact){
return list_selected.remove(contact);
}
public ArrayList<HashMap<String, String>> getSelectedItems(){
return list_selected;
}
access the list from activity as adapter.getSelectedItems();.
declare it in your activity as global
ListatoAdapter adapter;
set adapter in this way.
adapter = new ListatoAdapter(Activity2.this, list_serv);
list.setAdapter(adapter);
and get the list in button Click as.
ArrayList<HashMap<String,String> list = adapter.getSelectedItems();

Android TextView does not update

I know there are a lot of this kind of questions, but here is my problem.
I have a gallery with images and when I click, there is an ImageView to display the selected image in the gallery.
I also have a TextView witch displays a message.
When I click an image in the gallery, my ImageView gets the image and the TextTiew doesnt update its data.
I tried to put the code in a try/catch block and it doesn't throw any exception.
In my Log, the TextView has the exact text I have provided.
I tried using a new thread, but the result is the same: the TextView doesn't update, but my ImageView does.
I tried using runOnUiThread (as far as I know it's the same as a Thread), but still nothing.
I also changed from TextView to EditText, but I have the same problem.
Everyone says: "use a thread" - I did and it didn't work.
I ran out of ideas...

Declare your TextViews as field as like as ImageView---- "imgview" as follows...
public ImageView imgview;
public TextView title;
public TextView desc;
Initialize them in onCreate method as "imgview"
imgview = (ImageView)this.findViewById(R.id.imageView2);
title = (TextView) view.findViewById(R.id.editText2);
desc = (TextView) view.findViewById(R.id.editText4);
And update your gallery.setOnItemClickListener code as follows...
gallery.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View v, final int position, long id) {
title.setText(vod.get(position).title);
desc.setText(vod.get(position).description);
Log.i("info", title.getText()+" "+desc.getText());
imgview.setImageBitmap(getImageFromSD(vod.get(position).Icon));
}
});

You can set the header to by a textview. It will still be in the same format as a list view but the top item in the list view will be your text view

Your code is looking for R.id.text1
TextView tv = (TextView)findViewById(R.id.text1);
But your xml does not have any such id.
So you will get a null for tv.
