Question

I have a listview in my code and I want to set adapter on it.

But the issue is, even after initializing the listview, it is still null resulting into nullPointerException. (I checked it by logging and debugging)

I’m not able to access any view from that xml.

What am I missing? Any help appreciated.

xml

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:scrollbars="vertical" >

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" >

        <ListView
            android:id="@+id/lvToday"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:divider="#FFF"
            android:dividerHeight="2dp" />

        <ListView
            android:id="@+id/lvTomorrow"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@id/lvToday"
            android:divider="#FFF"
            android:dividerHeight="2dp" />
    </RelativeLayout>

</ScrollView>

Activity file

public class DashboardActivity extends Activity {

ListView lvToday, lvTomorrow;
TextView lblCall;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.dashboard);
    init();
}

private void init() {
    lvToday = (ListView) findViewById(R.id.lvToday);
    lvTomorrow = (ListView) findViewById(R.id.lvTomorrow);

    TodayAppAdapter adapter = new TodayAppAdapter(DashboardActivity.this,
            DashboardActivity.this);
                // This line is giving NULL
    lvToday.setAdapter(adapter);

    TomorrowAppAdapter adapter1 = new TomorrowAppAdapter(
            DashboardActivity.this, DashboardActivity.this);
                // This line is giving NULL
    lvTomorrow.setAdapter(adapter1);
}
}

1) test eclipse menu: Project -> Clean…

2) if you have more than one version for your xml layout (example layout-large, layout-xlarge,…), check if all of them have your view.
