Question

is it possible to have method startActivtyForResult within an adapter?Then how to get the response? Where to execute the call back function?

Answer 1

Yes.You can call startactivityforresult() from adapter.

There are two case- 1.Calling adapter from activity and need onActivityResult in activity. 2.Calling adapter from Fragment and need onActivityResult in fragment.

Case 1:Get OnActivityResult in Activity then pass the reference of activity to adapter constructor

public MyAdapter(Activity pActivity, List pList) {
        mList = pList;
        mActivity = pActivity;       
    }

Now startActivityForResult

Intent intent = new Intent(context, TargetActivity.class);
mActivity.startActivityForResult(intent, REQUEST_FOR_ACTIVITY_CODE);

Case 2: Get OnActivityResult in Fragment then pass the reference of fragment to adapter constructor

 public MyGamesAdapter(Fragment pContext, List pList,) {
        mList = pList;
        mMyFragment =pContext;
    }

 Intent intent = new Intent(context, TargetActivity.class);
    mMyFragment.startActivityForResult(intent, REQUEST_FOR_ACTIVITY_CODE);

Now in activity or fragment override OnActivityResult and get result.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    mAdapter.onActivityResult(requestCode, resultCode, data);
}
