when i click on the listview the bundle can get the value, but cant pass the value to second fragment. First Fragment
categorylist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
final String category = ((TextView) view.findViewById(R.id.mainproductitem)).getText().toString();
details_fragment ldf = new details_fragment ();
Bundle args = new Bundle();
args.putString("category", category);
ldf.setArguments(args);
}
});
return view;
}
Second Fragment
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
view=inflater.inflate(R.layout.my_fragment2, container, false);
test = (TextView)view.findViewById(R.id.textView);
Bundle args = getArguments();
if (args != null && args.containsKey("category")){
String userId = args.getString("category");
test.setText(userId);
}
return view;
}
You may be forget to start your second fragment
categorylist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
final String category = ((TextView) view.findViewById(R.id.mainproductitem)).getText().toString();
details_fragment ldf = new details_fragment ();
Bundle args = new Bundle();
args.putString("category", category);
ldf.setArguments(args);
FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.yourContainer, ldf);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
});
}
and in you second activity
Bundle agrs = getArguments();
if (args != null) {
String category = agrs.getString("category");
test.setText(category);
}
In First Fragment
categorylist.setOnItemClickListener(new AdapterView.OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
final String category = ((TextView) view.findViewById(R.id.mainproductitem)).getText().toString();
MainActivity main=new MainActivity();
main.openSecondFrag();
}
});
return view;
}
In your MainActivity,put openSecondFrag() method
public void openSecondFrag(){
details_fragment ldf = new details_fragment ();
Bundle args = new Bundle();
args.putString("category", category);
ldf.setArguments(args);
}
In Second Fragment
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
view=inflater.inflate(R.layout.my_fragment2, container, false);
test = (TextView)view.findViewById(R.id.textView);
Bundle args = getArguments();
if (args != null && args.containsKey("category")){
String userId = args.getString("category");
test.setText(userId);
}
return view;
}
I am sure it will work.
Try this: on your receiving Fragment:
Bundle agrs = this.getArguments();
if (args != null) {
String myStr = args.getString(key, defaultValue);
}
`Use this code in your categorylist.setOnItemClickListener`
// Create fragment and give it an argument specifying the article it should show
details_fragment newFragment = new details_fragment ();
Bundle args = new Bundle();
args.putString("category", category)
//Note: if your are in fragment than replace getSupportFragmentManager to getFragmentManager.
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack so the user can navigate back
transaction.replace(R.id.fragment_container, newFragment);
transaction.addToBackStack(null);
// Commit the transaction
transaction.commit();
Use a Bundle. Here's an example:
Fragment fragment = new Fragment();
Bundle bundle = new Bundle();
bundle.putString(key, value);
fragment.setArguments(bundle);
getFragmentManager().beginTransaction().replace(R.id.container_view, bundle).commit();
Bundle has put methods for lots of data types. See this
Then in your Fragment, retrieve the data (eg in onCreate() method) with:
Bundle bundle = this.getArguments();
if (bundle != null) {
int myInt = bundle.getString(key, defaultValue);
}

SecondFragment
public class SecondFragment extends Fragment {
public SecondFragment() {

}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.second_fragment, container, false);
TextView textView = (TextView)view.findViewById(R.id.textView);
view.setBackgroundColor(Color.WHITE);
String key = getArguments().getString("Key");
//Set the value to your text view
textView.setText(key);
return view;
}
I tried this out and it works perfectly.
