I have an activity with a listview. When the user click the item, the item "viewer" opens:
List1.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
Intent nextScreen = new Intent(context,ServicesViewActivity.class);
String[] Service = (String[])List1.getItemAtPosition(arg2);
//Sending data to another Activity
nextScreen.putExtra("data", datainfo);
startActivityForResult(nextScreen,0);
overridePendingTransition(R.anim.right_enter, R.anim.left_exit);
}
});
This works fine, but on the actionbar the back arrow next to the app icon doesn't get activated. Am I missing something?
Selvin already posted the right answer. Here, the solution in pretty code:
public class ServicesViewActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// etc...
getActionBar().setDisplayHomeAsUpEnabled(true);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
The function NavUtils.navigateUpFromSameTask(this)
requires you to define the parent activity in the AndroidManifest.xml file
<activity android:name="com.example.ServicesViewActivity" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.ParentActivity" />
</activity>
