Android的 - 导航抽屉片段 [英] Android - Navigation drawer fragments

问题描述

我已经在我的Andr​​oid应用程序来实现导航的抽屉里。但现在我希望能够使用的片段，当用户点击导航栏中的任何列表项改变布局。 以下是我有这么远：

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文件

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);
        }
    });
  }
}

使用上述code，我实现了抽屉式导航在我的应用程序，我见一，二和三列表项中的抽屉式导航，但没有任何反应，当我点击他们除了抽屉关闭。 所以，我的问题是： 如何添加片段功能上面给出code？

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?

我是初学者。在此先感谢！

I am beginner. Thanks in advance!

推荐答案

在点击有

  selectItem(pos);

然后

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;
     } 
}
