基于android创建带有标签的滑动视图

http://developer.android.com/training/implementing-navigation/lateral.html

如何使用自定义适配器获取列表视图并在此示例中使用？我的意思是显示简单的 textview ，显示为。

  <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="?android:attr/listPreferredItemHeight"
    android:padding="6dip" >

    <ImageView
        android:id="@+id/icon"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_alignParentBottom="true"
        android:layout_alignParentTop="true"
        android:layout_marginRight="6dip"
        android:contentDescription="TODO"
        android:src="@drawable/ic_launcher" />

    <TextView
        android:id="@+id/firstLine"
        android:layout_width="fill_parent"
        android:layout_height="26dip"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_toRightOf="@id/icon"
        android:ellipsize="marquee"
        android:singleLine="true"
        android:text="Description"
        android:textSize="12sp" />

    <TextView
        android:id="@+id/secondLine"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_above="@id/secondLine"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:layout_alignWithParentIfMissing="true"
        android:layout_toRightOf="@id/icon"
        android:gravity="center_vertical"
        android:text="Example application"
        android:textSize="16sp" />

  </RelativeLayout>

结果应为 Play 商店应用程序。

谢谢。

您可以尝试查看我的其他帖子：

Android 列表视图布局 类似于 Google play

无法使用 AndroidDrawer（侧边栏如 facebook）

也许这就是你正在寻找的：

如何在带有 android 的视图寻呼机页面中使用滑动手势？

试试这些链接..也许这就是你要找的。

这是一个更新

1）制作一个适配器来处理你的片段：

public class MyAdapter extends FragmentStatePagerAdapter {

    public MyAdapter(FragmentManager fm) {

        super(fm);

    }

    @Override
    public Fragment getItem(int index) {

        switch (index) {
        case 0:

            return new FirstFragment();

        case 1:

            return new SecondFragment();
        case 2:

            return new ThirdFragment();

        }
        return null;

    }

    @Override
    public int getCount() {
        return 3;
    }

}

2）添加片段：我只是添加一个片段的代码。你可以照着做。

public class FirstFragment extends Fragment {

    @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.somefragment, container, false);//You will have your custom layout and add more items. 

    return view;

}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onActivityCreated(savedInstanceState);

    TextView tv = (TextView)getActivity().findViewById(R.id.textview1);
    //You can add different items in here according to your needs. 
    //You will have your own code to do stuff. Like to use a listview or a gridview etc. You will make a separate adapter in a separate class and use that adapter in this onActivityCreated() method.
}


}

3）修改MainActivity：

public class AllActivities extends FragmentActivity implements ActionBar.TabListener {

    public ViewPager viewPager;
    private MyAdapter mAdapter;
    private ActionBar actionBar;
    private String [] tabs = {"FirstFragment","SecondFragment","ThirdFragment"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //Initializing all stuff
        viewPager = (ViewPager)findViewById(R.id.pager);

        actionBar = getActionBar();
        mAdapter = new MyAdapter(getSupportFragmentManager());
        viewPager.setAdapter(mAdapter);
        actionBar.setHomeButtonEnabled(true);
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);



        //Add the tabs here
        for(String tab_name:tabs){
            actionBar.addTab(actionBar.newTab().setText(tab_name).setTabListener(this));
        }

        viewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener(){

            @Override
        public void onPageSelected(int position){

                //on Page change, that particular page should be selected
                actionBar.setSelectedNavigationItem(position);
            }

            @Override
                public void onPageScrolled(int arg0,float arg1,int arg2){

            }
            @Override
        public void onPageScrollStateChanged(int position){

            }

        });
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public void onTabSelected(Tab tab, FragmentTransaction fragmentTransaction) {

        viewPager.setCurrentItem(tab.getPosition());
    }

    @Override
    public void onTabUnselected(Tab tab, FragmentTransaction fragmentTransaction) {



    }

    @Override
    public void onTabReselected(Tab tab, FragmentTransaction fragmentTransaction) {

        viewPager.setCurrentItem(tab.getPosition());

    }
}

在你实现了这个例子之后，你就不用担心这个 MainActivity 了。您只需添加更多片段就是将片段添加到您的适配器并根据它构建页面。另外，添加 private String [] tabs = {"FirstFragment","SecondFragment","ThirdFragment","You other fragments when you will define"};

要使 google play 像导航抽屉一样，您可以参考我的前两个链接，然后按照您的喜好进行操作。

希望这对您正在寻找的内容有所帮助。
