Question

I need to refresh my activity. I have bunch of question regrading the same which advice me to finish current activity and restart the current activity. OR again provide value to each widget. To avoid transition I used this code

Intent intent = getIntent();
overridePendingTransition(0, 0);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
this.finish();

overridePendingTransition(0, 0);
startActivity(intent);

But in my case In my activity I have four tabs, and I need to refresh all four tabs.

There are few more problems regarding the same
1) With above code, if I am on other screen, I come back to this screen when above piece of code runs.

2) Activity sequence gets disturb.

3) Maintaining selected tab will also be a part of problem

Even if I try to refresh each tab seperatley, One of my tab have webview. how to refresh that as webview.loadData() can’t be called unless there is view and since I am not on that tab there will no view.

What can be the ideal way to tackle this problem. Any help will be appreciated.

Answer 1

Question was not much complicated but solution what I wanted got to be optimised. Finally I took the second way, ie refreshing each component. This approach overcomes the problem of disturbing the sequence of activity. For web view I am still using webView.loadData(...).

In total I have handeled each tab separately. If I include my entire code then it would become clumsy, but still trying to incorporate as many important feature.

In my activity class when I need to refresh my activity, I called this method.

private void onRefrash()
{   
    refreshCurrentActivity();

    int selectedTab = getActionBar().getSelectedNavigationIndex();
    switch (selectedTab)
    {
    case TAB1:
        fragment1.update();
        break;
    case TAB2:
        fragment2.update();
        break;
    case TAB3:
        fragment3.update();
        break;
    }       
Toast.makeText(this, getString(R.string.msg_case_updates_received), Toast.LENGTH_LONG).show();  
    }                       
}

Each fragment is earlier initialised, and update method is called for each tab in which I am updating the corresponding web view.
