I'm trying to make a slight adjustment to the positioning of the selected item in the spinner. Not the dropdown list items, as I already have a custom view in my adapter for that, but the selected item specifically.
As you can see in the screenshot, "Any" is the currently selected item. But it is aligned oddly within the container because it has to accommodate the longest string in the dropdown, which is "Dark Purple Burnt Sienna" (or whatever). I want to align the selected text to the right so that "Any" is next to the dropdown indicator instead of way out in the middle.
I've attempted to make adjustments to my custom spinner-item view, but it doesn't have any affect on the selected item.
I've also attempted to set gravity and text alignment on the Spinner itself, but it has no effect.
Here's the image and the xml:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="@color/default_black"
android:layout_centerVertical="true"
android:text="Color" />
<Spinner
android:id="@+id/spn_color"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
</RelativeLayout>
Edit: Here's my adapter:
public class ColorsAdapter<T> implements SpinnerAdapter {
ArrayList<String> mColors;
ArrayList<Integer> mValues;
Context mContext;
public ColorsAdapter(ArrayList<String> colors, ArrayList<Integer> values,
Context context) {
mContext = context;
mColors = colors;
mValues = values;
}
@Override
public int getCount() {
return mColors.size();
}
@Override
public Object getItem(int position) {
return mColors.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public int getItemViewType(int position) {
return R.layout.list_item_color;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView v = new TextView(mContext);
v.setText(mColors.get(position));
return v;
}
@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(
Context.LAYOUT_INFLATER_SERVICE );
View row = inflater.inflate(getItemViewType(position), parent, false);
TextView tvName = (TextView)row.findViewById(R.id.tv_name);
tvName.setText(mColors.get(position));
row.setTag(mValues.get(position));
return row;
}
@Override
public int getViewTypeCount() {
return 1;
}
@Override
public boolean hasStableIds() {
return false;
}
@Override
public boolean isEmpty() {
return false;
}
}
And here's the XML for the list item:
<TextView
android:id="@+id/tv_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:gravity="right"/>
