How to use onActivityForResult from one activity in another activity
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am currently adding more features to a github project for my personal use. I need to create a list of applications to be shown in a grid view by either:
1. Writing package name by myself (this functionality already existed) or
2. Selecting from a list of apps (what i want to achieve) - all functionality is implemented in ChooserActivity using ChooserAdapter.
What would solve my problem is to pass information to the MainActivity and call its onActivityResult method, since there is a lot of things i cannot copy paste it.
For the clickListener (of each grid view item) I created the OnItemClickListener interface in ChooserAdapter and overriden it in the ChooserActivity.
ChooserActivity:
class ChooserActivity : BaseActivity(), ChooserAdapter.OnItemClickListener {
private val backButton: FloatingActionButton by bindView(R.id.back_button_2)
override fun onItemClick(app: ApplicationInfo?) {
val intent = EditorActivity.IntentBuilder(context)
.build()
startActivityForResult(intent, 1)
}
public override fun onActivityResult(requestCode: Int, resultCode: Int, intent: Intent?) {
Toast.makeText(this, "onActivityResult called ...", Toast.LENGTH_SHORT).show()
// !!!!!!
MainActivity().onActivityResult(requestCode, resultCode, intent)
//How can I write something similar to this to solve my problem?
}
ChooserAdapter:
public class ChooserAdapter extends RecyclerView.Adapter<ChooserAdapter.ChooserHolder>{
private List<ApplicationInfo> listOfApps;
private Context mContext;
private PackageManager pm;
private OnItemClickListener listener;
public ChooserAdapter(@NonNull Context context, List<ApplicationInfo> list, OnItemClickListener l) {
this.listOfApps = list;
this.mContext = context;
this.pm = context.getPackageManager();
this.listener =
new ChooserAdapter.OnItemClickListener(){
@Override
public void onItemClick(ApplicationInfo app){
try{
Intent intent = (new EditorActivity.IntentBuilder(mContext)).build();
((ChooserActivity)mContext).startActivityForResult(intent, 2);
}catch (Exception e){
Toast.makeText(mContext, "Error: " + e.getMessage(), Toast.LENGTH_LONG).show();
}
}
};
}
public class ChooserHolder extends RecyclerView.ViewHolder{
//stuff not useful to be shown
}}
The result of the above code resulted in not using the wanted MainActivity().onActivityResult(...), but the ChooserActivity's method.

You have to start ChooserActivity with startActivityForResult() from MainActivity and then pass result in this way EditorActivity -> ChooserActivity -> MainActivity
class ChooserActivity : BaseActivity(), ChooserAdapter.OnItemClickListener {
....
public override fun onActivityResult(requestCode: Int, resultCode: Int, intent: Intent?) {
Toast.makeText(this, "onActivityResult called ...", Toast.LENGTH_SHORT).show()
setResult(Activity.RESULT_OK, intent)
finish()
}
....
}
Override onActivityResult(...) in MainActivity and handle result
