i am making an android 4.03 application and i am using tabs with fragments
in each fragment i need a searchView so i can search the list in my
fragments.
each fragment has a code like this
@Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
>> {
>
> inflater.inflate(R.layout.menu_items_docent, menu);
>
> SearchView sv = (SearchView)
>> menu.findItem(R.id.menu_search_docent).getActionView();
>
> sv.setOnQueryTextListener(this);
>
>
>
> }
>
>
>
> @Override
>
> public boolean onOptionsItemSelected(MenuItem item) {
>
> switch (item.getItemId()) {
>
> case R.id.menu_refresh_docent:
>
>
>
> return true;
>
> default:
>
> return super.onOptionsItemSelected(item);
>
> }
>
> }
>
>
>
> @Override public boolean onQueryTextChange(String newText) {
>
> System.out.println(newText);
>
> mCurFilter = !TextUtils.isEmpty(newText) ? newText : null;
>
> try{
>
> mAdapter.getFilter().filter(mCurFilter);}
>
> catch(Exception e){}
>
> return true;
>
> }
>
>
>
> @Override public boolean onQueryTextSubmit(String query) {
>
> return true;
>
> }
>
>
if i don't have the try catch i get an error when i switch the tabs

and when i leave the try catch it takes the searched text from the 1
fragment to the other.
but it need to be removed.
this is the menu items xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android";>
<item android:id="@+id/menu_search_docent"
android:title="@string/Search"
android:icon="@drawable/ic_menu_search"
android:showAsAction="ifRoom"
android:actionViewClass="android.widget.SearchView" />
<item android:id="@+id/menu_refresh_docent"
android:icon="@drawable/ic_refresh_hd"
android:title="@string/Refresh"
android:showAsAction="ifRoom|withText" />
</menu>
also i use for each tab its own xml because i thought maybe that would help.
Thanks Lars.
