Select tab within fragment

First of all, awesome library. I am just curious, is it possible to select specific tab from a fragment? I have 5 different fragments, and i need to update my activity to see changes. If i do so, i need to go to the previous tab. This is bad for the end user, cause he lands on the first tab.

How could i attach the BottomBar within fragment and then select tab like this: mBottomBar.selectTabAtPosition(3, false); Thanks a lot! 👍

@mag2007, Sure. So in your MainActivity where you define BottomBar, make it public static like,

public class MainActivity extends Activity {
...
public static BottomBar mBottomBar;
@Override
   protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        whateverYouWantDone();
    }
    ...
}

And then in your fragment you can access it using MainActivity.mBottomBar

public class FragmentA extends Fragment {
    ...
    void doSomeOperationWithBottomBar(){
    MainActivity.mBottomBar.selectTabAtPosition(3, false); //Since mBottomBar is static, you can get it's reference in any class
    }
    ...
}

@mag2007 @PsyGik i would TOTALLY advice AGAINST this approach, you should not be depending in things like this to be inside static variables, also because you are making this static this means that the Context and all the things attached to it will be kept alive FOR EVER. Also if that wasn’t enough if your activity were to appear more than one time, the latest one will override the first one and then you get into a weird state that will create very hard to debug problems. please DON’T DO THIS, and read all the android best practices in the developer documentation.
