When I apply OnItemClickListener it does not do any action like intent inside the func not called. I tried toast too but nothing shown on clicking the listView Items.
I also tried OnItemSlectedListener , it also not worked for me.
What is the problem here with this code. ?
Thanks Every One. Issue was with autolink on email and phone, I make their focusable=false but nothing happened.Then I remove it and guess what? Clicklistener also starts working.
The attribute android:clickable="true" in your ListView could be overriding all of click events of its child views, you should probably remove it:
<ListView
android:clickable="true" <!-- Remove this attribute -->
android:id="#+id/listView_emp_directory_xml"
android:layout_below="#id/relatice_layout_header_emp_directory_activity_xml"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
I want to make Screen in android with multiple layouts. Fox example On the top of the screen there is the header with image slider (this part is done) below that there will be a list view and below that there will be grid view.

How to make multiple layout for one screen?
my approach for this goal is using Fragments
how?
i do make a single main_layout and set a FrameLayout in order to put fragments with different layouts.so i have a screen with different layouts.
this is my best answer for your question .
I am beginner Android Developer. I want to create an Android Page which will dynamically display Three things 1. Question No. 2. Your Answer 3. Right Answer. How can I do this? It should look like this and can grow dynamically

questionArrayList = new ArrayList<>();
for (int i = 0; i < 12; i++) {
questionArrayList.add(new Question(i,"myans","yourans"));
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fillList();
ListView mlIstView = (ListView)findViewById(R.id.mListview);
QuestionAdapter adapter = new QuestionAdapter(this,R.layout.listviewlayout,questionArrayList);
mlIstView.setAdapter(adapter);
}
}
Question.java

I'm working on a little app which is supposed to display 3 screens : Talks, Papers and Choices. I've discovered fragments a few days ago and I would like to use this feature for my app, but unfortunately, it doesn't work for a particular reason…
My fragment:
package info.androidhive.tabsswipe;

public class PapersFragment extends Fragment {

private Context myContext;
List<Paper> papers = null;
private List<Paper> papersParser () {
try {
XMLParser2 parser = new XMLParser2();
papers = parser.parse(getActivity().getApplicationContext().getAssets().open("talks.xml"));
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return papers;
};
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_papers, container, false);
ListView lv = (ListView) getActivity().findViewById(R.id.check1);
listAdapter = new PaperAdapter(getActivity(),papers);

CheckBox cb = (CheckBox) view.findViewById(R.id.check1);
//cb.setChecked(p.isSelected());
// We tag the data object to retrieve it on the click listener.
TextView paper = (TextView)view.findViewById(R.id.papername);

paper.setText(p.getTitle());

If I leave
//lv.setAdapter(listAdapter);
commented, it loads, but as soon as I uncomment it, it crashes with the following error:
12-06 11:28:05.240: E/AndroidRuntime(1362): java.lang.ClassCastException: android.widget.TextView cannot be cast to android.widget.ListView
with reference to this precise line.
You make cast checkBox to ListView !
It should be like that.
ListView lv = (ListView) getActivity().findViewById(R.id.list);
I gusse here is the error in your code:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_papers, container, false);
ListView lv = (ListView) getActivity().findViewById(R.id.check1);
//Here your casting checkBox to Listview Pleas Check it out
listAdapter = new PaperAdapter(getActivity(),papers);
//lv.setAdapter(listAdapter);
return v;
}
just replace it like
ListView lv = (ListView) v.findViewById(R.id.ListviewName);
