The getView() method of ArrayAdapter is not getting called
I am very new to android development. I am trying to a build an application with tags (which are added through fragments). In one of the fragments, I am trying to display a list. This list has been populated using ListAdapter which I have extended from ArrayAdapter and I have overloaded getView() method. This is my fragment
public class tabcontentActivity extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (container == null) {
return null;
}
View v = (LinearLayout) inflater.inflate(R.layout.tablayout, container,
false);
ListView lv = (ListView) v.findViewById(R.id.listview1);
ListViewAdapter adapter = new ListViewAdapter(container.getContext(),
android.R.layout.simple_list_item_1, R.id.textview1);
adapter.notifyDataSetChanged();
lv.setAdapter(adapter);
return v;
}
}
And this is how I have implemented the ListAdapter
public class ListViewAdapter extends ArrayAdapter {
Context context1;
public ListViewAdapter(Context context,int resource, int textViewResourceId) {
super(context,resource,textViewResourceId);
this.context1 = context;
System.out.println("here aswell!!!!!!");
// TODO Auto-generated constructor stub
}
public View getView(int arg0, View convertView, ViewGroup arg2) {
// TODO Auto-generated method stub
System.out.println("@@@I AM HERE@@@");
LayoutInflater inflater = LayoutInflater.from(context1);
convertView = inflater.inflate(R.layout.tablayout, null);
TextView wv = (TextView) convertView.findViewById(R.id.textview1);
String summary = "<html><body><h1>This is happening!!!</h1></body></html>";
wv.setText(Html.fromHtml(summary));
convertView.setTag(wv);
return convertView;
}
}
The layout xml is
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView
android:id="@+id/listview1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</ListView>
<TextView
android:id="@+id/textview1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="myreader" />
</LinearLayout>
Please help me to find a way by which I can make this work.
Answer
You just forgot to provide the data to the constructor and then make the correct call within the constructor:
public ListViewAdapter(Context context,int resource, int textViewResourceId, List<YourObjectType> items) {
super(context,resource,textViewResourceId, items);
this.context1 = context;
// TODO Auto-generated constructor stub
}
