In my application i have an class extending dialog fragment. The class displays normal dialog(not Alert dialog).
1.displaying a listview inside dialog. the list view contains 2 text views , both are populated by 2 string arrays. I am confused about which adapter to use other than base adapters
2.how to inflate a layout for dialog. Is setView method available only for alert dialog
The only way to use a layout in a Dialog is to subclass it:
class MyDialog extends Dialog{
public MyDialog(Context context) {
super(context);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dialog);
String[] arr1 = new String[]{"title1", "title2", "title3"};
String[] arr2 = new String[]{"content1", "content2", "content3"};
ListView list = (ListView)findViewById(R.id.list);
list.setAdapter(new MyAdapter(arr1, arr2));
}
where R.layout.dialog is your layout where your listView is defined, which we will set a Custom Adapter, inflating a layout containing the two strings.
private final class MyAdapter extends BaseAdapter{
private String[] mArray1;
private String[] mArray2;
public MyAdapter(String[] arr1, String[] arr2) {
mArray1 = arr1;
mArray2 = arr2;
}
public int getCount() { return mArray1.length; }
public Object getItem(int position) { return mArray1[position]; }
public long getItemId(int position) { return 0; }
public View getView(int position, View convertView, ViewGroup parent) {
String str1 = mArray1[position];
String str2 = mArray2[position];
if(convertView==null){
LayoutInflater li = getLayoutInflater();
convertView = li.inflate(R.layout.my_list_cell, null);
}
TextView text1 = (TextView)convertView.findViewById(R.id.text1);
text1.setText(str1);
TextView text2 = (TextView)convertView.findViewById(R.id.text2);
text1.setText(str2);
return convertView;
}
}
If you want to display the data inside the dialog using an Adapter, you could use a ListAdapter. It could be something like this :
ListAdapter adapter = new ArrayAdapter<String>(context, android.R.layout.select_dialog_item, android.R.id.text1, items) {
public View getView(int position, View convertView, ViewGroup parent) {
// Do something here
return view;
}
};
which adapter to use other than base adapters
=> There is no restriction. You can use and customize any adapter as per your requirement. for example, you can use ArrayAdapter e.g. ArrayAdapter<JSONObject> or ArrayAdapter<String>.
