I want the spinner displays ImageView+TextView, so I create two
classes as below:
public class AlbumSpinnerItem extends LinearLayout {
private ImageView mAlbumType;
private TextView mAlbumName;
public AlbumSpinnerItem(Context context, String text, int
resourceId) {
super(context);
this.setOrientation(HORIZONTAL);
this.mAlbumType = new ImageView(context);
this.mAlbumType.setImageResource(resourceId);
this.mAlbumName = new TextView(context);
this.mAlbumName.setText(text);
// Add child views to this object
LinearLayout.LayoutParams param1 = new
LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
param1.gravity = Gravity.LEFT;
this.addView(this.mAlbumType, param1);
LinearLayout.LayoutParams param2 = new
LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
param2.gravity = Gravity.RIGHT;
this.addView(this.mAlbumName, param2);
}
}
public class AlbumSpinnerAdapter extends
ArrayAdapter<AlbumSpinnerItem> {
Context c;
List<AlbumSpinnerItem> s;
public AlbumSpinnerAdapter(Context context, int
textViewResourceId,
List<AlbumSpinnerItem> objects) {
super(context, textViewResourceId, objects);
c = context;
s = objects;
}
@Override
public View getDropDownView(int position, View convertView,
ViewGroup parent) {
if (position<s.size())
return s.get(position);
else
return null;
}
@Override
public View getView(int position, View convertView, ViewGroup
parent) {
if (position<s.size())
return s.get(position);
else
return null;
}
@Override
public int getCount() {
return s.size();
}
}
But I get the following error information:
