At the moment it is main activity but I want to change it to the Categories activity. Is this where the problem lies?
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
// This ID represents the Home or Up button. In the case of this
// activity, the Up button is shown. Use NavUtils to allow users
// to navigate up one level in the application structure. For
// more details, see the Navigation pattern on Android Design:
//
// http://developer.android.com/design/patterns/navigation.html#up-vs-back
//
NavUtils.navigateUpFromSameTask(this);
return true;
}
return super.onOptionsItemSelected(item);
Go to AndroidManifest.xml
, find your Sport activity and add this code
<activity android:name="Sport" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="PARENT_ACTIVITY_PATH" />
</activity>
Substitute PARENT_ACTIVITY_PATH
with the name of your parent activity adding also your package name (e.g. com.example.Categories).
