I'm moving my first steps into android, so sorry if this is a stupid question.
I've followed this tutorial to implement a DialogFragment
containing a ListView
.
This is the ColorDialogFragment.java
:
public class ColorDialogFragment extends DialogFragment {
String[] listItems = { "Red", "Blue", "Green"};
ListView myList;
String ipAddress;
public static ColorDialogFragment newInstance(String ipAddress) {
Bundle args = new Bundle();
args.putString("ipAddress",ipAddress);
ColorDialogFragment fragment = new ColorDialogFragment();
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ipAddress = getArguments().getString("ipAddress");
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.dialog_fragment, null, false);
myList = (ListView) view.findViewById(R.id.list);
getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
return view;
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_1, listItems);
myList.setAdapter(adapter);
myList.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
String colorHex;
switch (i){
case 1:
colorHex = "#FF0000";
break;
case 2:
colorHex = "#0000FF";
break;
case 3:
colorHex = "#00FF00";
break;
default:
dismiss();
return;
}
ClientAsyncTask clientAsyncTask = new ClientAsyncTask(ipAddress, colorHex);
clientAsyncTask.execute();
dismiss();
}
});
}
private class ClientAsyncTask extends AsyncTask<Void, Void, Void> {
...
}
}
And this is dialog_fragment.xml
:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp" >
<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</ListView>
</LinearLayout>
</LinearLayout>
The problem is that when I click a list item onItemClick()
is not called (and obviously I don't understand why).
I found out by myself that the problem were the wrong indexes in switch
statement (starting from 0 and not from 1, obviously).
