i am trying to implement listView through setListAdapter and Efficient Adapter. I want that when list is show then the background should not be repeat. My code is repeating the whole layout of list.xml due to which my list item are showing with so much gap.
Right now my list is working like that:
But i want this type of view:
Here is my editText.xml in which i type the word and a list View is opened.
<EditText
android:id="@+id/start_edit"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_gravity="top|left"
android:ems="10"
android:hint="Type to search"
android:paddingLeft="50dp" >
<requestFocus />
</EditText>
this layout is for list.xml :
<RelativeLayout
android:id="@+id/RelativeLayout_list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/blue_cellbar" >
the list.xml file is repeating the layout in Effecient adapter:
here is my code:
listAdapter = new EfficientAdapter2(this);
setListAdapter(listAdapter);
public static class viewHolder2 {
TextView word;
TextView meaning;
ImageView image;
ImageView image_color;
RelativeLayout cell;
}
private class EfficientAdapter2 extends BaseAdapter implements Filterable,OnItemClickListener {
private Context context;
LayoutInflater inflater;
public EfficientAdapter2(Context context) {
this.context = context;
inflater = LayoutInflater.from(context);
}
public int getCount() {
// if(SearchWordString.isEmpty()==false)
// {
return SearchWordString.size();
/// }
//return 0;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
viewHolder2 holder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.list, null);
ViewToUse=parent;
holder = new viewHolder2();
// Log.i("View","is Null");
convertView.setTag(holder);
} else {
//Log.i("View","is not Null");
holder = (viewHolder2) convertView.getTag();
}
holder.cell = (RelativeLayout) convertView
.findViewById(R.id.RelativeLayout_list);
return convertView;
}
UPDATE
public class Start extends ListActivity implements OnTouchListener,
android.view.GestureDetector.OnGestureListener {
// ////////////////////////////////////////////////////

onCreate()
{
ListView list_to_use = getListView();
listAdapter = new EfficientAdapter2(this);
list_to_use.setAdapter(listAdapter);
list_to_use.setBackgroundColor(2);
viewFlipper = (ViewFlipper) findViewById(R.id.viewFlipper1);
search = (EditText) findViewById(R.id.start_edit);
search.addTextChangedListener(myTextWatcher);
}
public static class viewHolder2 {

I hope you have not provide
android:dividerHeightattribute in your layout file under<ListView/>If so please remove it.
