Answer 2

if i want to go back to an Activity to another activity i override on back pressed and using intent call that actvity

Normally, if you want to go back you don't have to do something. Pressing the device's hardware Back button will take you to the previous activity with the corresponding tab already opened.

Answer 3

enter image description here

@Override
public void onBackPressed() {
  //Here "digiM" is an Actionbar Title
    if(getTitle().equals("digiM") || getSupportActionBar().getTitle().equals("digiM"))
    {
        //reload the activity if you want to open it again as your need
        Intent intent = new Intent(Your_Current_Activity.this,Your_Current_Activity.class);
        startActivity(intent);
    }
}

If you have action bar in that fragment, then you can check action bar title on onBackPressed() in Activity which contains method like.

Answer 4

First, Override the back press to goto the activity where the fragments are :-

@Override
public void onBackPressed()
{

    Intent intent = new Intent(CurrentActivity.this,ActivityYouLikeToGo.class);

    intent.putExtra("Check",1);
    startActivity(intent);
}

then goto the ActivityYouLikeToGo.java file and in onCreate do this:-

Intent intent = getIntent();
String s1 = intent.getStringExtra("Check");

if(s1.equals("1"))
  {
s1 = "";
Fragment fragment = new YOURFRAMENTNAME();
if (fragment != null) {
            FragmentManager fragmentManager = getFragmentManager();
            fragmentManager.beginTransaction()
                    .replace(R.id.frame_container, fragment).commit();
  }
}
