Android - Navigation drawer fragments

android, android-fragments, android-navigation

Solution

On click have

  selectItem(pos);

Then

public void selectItem(int position)
{
     switch(position)
     {
          case 0:
                     // fragment1
                     // use fragment transaction and add the fragment to the container
                     FragmentManager fragmentManager = getFragmentManager()
                     FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();   
                     Fragment1 fragment = new Fragment1();
                     fragmentTransaction.add(R.id.content_frame, fragment);
                     fragmentTransaction.commit();

          break;
          case 1:
                     // fragment2
          break; 
          case 2:
                     // fragment2
          break;
     } 
}

Problem

I have implemented navigation drawer in my android app. but now I want to be able to change the layout using fragments when the user clicks any list item in the navigation bar. Here is what I have got so far: XML ``` <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/drawer_layout" android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="match_parent"> <FrameLayout android:id="@+id/content_frame" android:layout_width="match_parent" android:background="#000000" android:layout_height="match_parent" > </FrameLayout> <ListView android:id="@+id/left_drawer" android:layout_width="220dp" android:layout_height="match_parent" android:layout_gravity="start" android:choiceMode="singleChoice" android:divider="@android:color/transparent" android:dividerHeight="0dp" android:background="#111"/> </android.support.v4.widget.DrawerLayout> ``` Java File ``` public class MainActivity extends Activity { final String[] data ={"one","two","three"}; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, data); final DrawerLayout drawer = (DrawerLayout)findViewById(R.id.drawer_layout); final ListView navList = (ListView) findViewById(R.id.left_drawer); navList.setAdapter(adapter); navList.setOnItemClickListener(new AdapterView.OnItemClickListener(){ @Override public void onItemClick(AdapterView<?> parent, View view, final int pos,long id){ drawer.setDrawerListener( new DrawerLayout.SimpleDrawerListener(){ @Override public void onDrawerClosed(View drawerView){ super.onDrawerClosed(drawerView); } }); drawer.closeDrawer(navList); } }); } } ``` Using the above code, I implemented navigation drawer in my app and I see "one", "two" and "Three" list items in the navigation drawer but nothing happens when I click on them except the drawer closes. So, my question is : How do I add the fragment functionality to the above given code? I am beginner. Thanks in advance!
