是否需要从主屏幕小部件转到mainActivity中的片段？

Question

Need to go to a Fragment in my MainActivity from a home screen Widget . In my MainActivity The first view is a ListView in a Fragment , there is an add button to enter in some data and this add button opens a Fragment that has some EditText in it and on save it adds the entered data into the ListView back in the main Fragment so here's my problem. I can get back to the MainActivity by calling

Intent details = new Intent(context, MainActivity.class); 
details.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(details);

and that gets me back to the main Fragment with the Listview but how could I get back to the Fragment that is called to enter the data on a Button click in the MainActivity . From the home screen Widget I would like to open the enter data Fragment not the main Fragment ?

Answer 1

Define the Intent as

Intent details = new Intent(context, MainActivity.class); 
details.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
details.putExtra("data", "data");
context.startActivity(details);

In your MainActivity 's onCreate() method:

if(getIntent().hasExtra("data")){

  // call Enter data Fragment (via FragmentManager)

}
else{

  // call ListView Fragment (via FragmentManager)

}

Try this. This should work.
