Fragment中使用listview

按照步骤来就可以达到效果：

1-新建一个listview.xml

是listview中每个items的样式

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#f1e4f1"
        android:orientation="horizontal">

        <ImageView
            android:id="@+id/image"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />

        <TextView
            android:id="@+id/title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="#666872" />

        <Button
            android:id="@+id/view"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="详细" />
    </LinearLayout>

    <TextView
        android:id="@+id/info"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#666872" />
</LinearLayout>

2-新建一个适配器类

public class ListViewAdapter extends BaseAdapter {

    private List<Map<String, Object>> data;
    private LayoutInflater layoutInflater;
    private Context context;
    public ListViewAdapter(Context context,List<Map<String, Object>> data){
        this.context=context;
        this.data=data;
        this.layoutInflater=LayoutInflater.from(context);
    }
    /**
     * 组件集合，对应list.xml中的控件
     * @author Administrator
     */
    public final class Zujian{
        public ImageView image;
        public TextView title;
        public Button view;
        public TextView info;
    }
    @Override
    public int getCount() {
        return data.size();
    }
    /**
     * 获得某一位置的数据
     */
    @Override
    public Object getItem(int position) {
        return data.get(position);
    }
    /**
     * 获得唯一标识
     */
    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        Zujian zujian=null;
        if(convertView==null){
            zujian=new Zujian();
            //获得组件，实例化组件
            convertView=layoutInflater.inflate(R.layout.home_listview, null);
            zujian.image=(ImageView)convertView.findViewById(R.id.image);
            zujian.title=(TextView)convertView.findViewById(R.id.title);
            zujian.view=(Button)convertView.findViewById(R.id.view);
            zujian.info=(TextView)convertView.findViewById(R.id.info);
            convertView.setTag(zujian);
        }else{
            zujian=(Zujian)convertView.getTag();
        }
        //绑定数据
        zujian.image.setBackgroundResource((Integer)data.get(position).get("image"));
        zujian.title.setText((String)data.get(position).get("title"));
        zujian.info.setText((String)data.get(position).get("info"));
        return convertView;
    }

}

• 3-在fragment的布局文件中（如main_fragment.xml）添加Listview控件

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:materialdesign="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
    <!-- ... XML CODE -->
    <ListView
           android:id="@+id/listview"
            android:layout_width="fill_parent"
           android:layout_height="fill_parent">

    </ListView>
</RelativeLayout>

4-在Fragment.java中调用Listview

public class FragmentIHome extends BaseFragment{

    private ListView listView;
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view= inflater.inflate(R.layout.home_fragment , container, false);
        listView = (ListView)view.findViewById(R.id.listview);
        List<Map<String, Object>> list=getData();
        listView.setAdapter(new ListViewAdapter(getActivity(), list));
        return view;
    }

    public List<Map<String, Object>> getData(){
           List<Map<String, Object>> list=new ArrayList<Map<String,Object>>();
              for (int i = 0; i < 10; i++) {
                       Map<String, Object> map=new HashMap<String, Object>();
                       map.put("image", R.drawable.ic_launcher);
                       map.put("title", "这是一个标题"+i);
                   map.put("info", "这是一个详细信息" + i);
                       list.add(map);
                   }
          return list;
    }
}
