android adapter Onclick open new activty

Question

I am using this code for make new listener for every new item

first the xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/list_row_selector"
android:padding="8dp"
android:id="@+id/showonmap"
android:alpha="0.9">

<!-- Thumbnail Image -->

<!-- notofocation  Title -->
<TextView
    android:id="@+id/title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="15dp"
    android:textStyle="bold" />

<!--   -->
<TextView
    android:id="@+id/rating"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_below="@id/title"
    android:layout_marginTop="1dip"
    android:textSize="@dimen/rating" />

<!-- Genre -->
<TextView
    android:id="@+id/genre"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_below="@id/rating"
    android:layout_marginTop="5dp"
    android:textColor="@color/genre"
    android:textSize="@dimen/genre" />

<!-- date -->
<TextView
    android:id="@+id/releaseYear"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:textColor="@color/year"
    android:textSize="@dimen/year" />

I just parse the JSON array response and make new item depend on array length

after that I add listener to the

.. RelativeLayout with id showonmap

and when click on its it open new activity the code of Onclick

showonmaps.setOnClickListener(new View.OnClickListener() {


        public void onClick(View view) {


            Intent intent = new Intent(context, show_notification.class);
            intent.putExtra("lat", m.getGenre().get(0));
            intent.putExtra("lang", m.getGenre().get(1));
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);


            context.startActivity(intent);





        }
    });

here I am using

  intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
  context.startActivity(intent);

and when use

Intent intent = new Intent(context,
                            show_notification.class);
                    context.startActivity(intent);

the application stopped so i must back and use

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
  context.startActivity(intent);

but when I use it and open new activity and press back button its exit from the application any idea or solution ?

Remove this line: `intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);`. When setting this flag you are basically starting a new activity stack. I see that your applicaiton crashed when removing, so you are probably using a context which is not allowed to launch an Activity i.e. an application context (`getApplicationContext()`) — 0xDEADC0DE, May 02 '16 at 11:09
use this yourActivity.this instead of context like,Intent intent = new Intent(yourActivity.this, show_notification.class); startActivity(intent); — Pradeep Gupta, May 02 '16 at 11:11
@PradeepGupta its not activity its a class public class CustomListAdapter extends BaseAdapter and i just pass the context when construct the class — Максим Зубков, May 02 '16 at 11:12
it would be better to know why the application stopped when clicked on back button, attach a log section of the crash — visionix visionix, May 02 '16 at 11:17
@visionixvisionix its give me this Calling startActivity() from outside of an Activity context — Максим Зубков, May 02 '16 at 11:23
