标准的ListView使用（带缓存）

以笑话列表为例

1、新建Joke.java类

/**
 * Created by Jorble on 2016/3/1.
 */
public class Joke {
    private String title;
    private String content;
    private String type;
    private String updatatime;

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getUpdatatime() {
        return updatatime;
    }

    public void setUpdatatime(String updatatime) {
        this.updatatime = updatatime;
    }
}

2、新建布局文件item_list_joke.xml

<?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="45dp"
        android:orientation="horizontal">
        <TextView
            android:id="@+id/title"
            android:layout_width="wrap_content"
            android:layout_height="match_parent" />
        <TextView
            android:id="@+id/type"
            android:layout_width="wrap_content"
            android:layout_height="match_parent" />
        <TextView
            android:id="@+id/updatatime"
            android:layout_weight="1"
            android:layout_width="0dp"
            android:layout_height="match_parent" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1">
        <TextView
            android:id="@+id/content"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </LinearLayout>

</LinearLayout>

3、新建列表适配器JokeListAdapter类(带添加、删除功能)

public class JokeListAdapter extends BaseAdapter {

    private LinkedList<Joke> mData;
    private Context mContext;

    public JokeListAdapter(LinkedList<Joke> mData, Context mContext) {
        this.mData = mData;
        this.mContext = mContext;
    }

    @Override
    public int getCount() {
        return mData.size();
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        ViewHolder holder = null;
        if(convertView == null){
            convertView = LayoutInflater.from(mContext).inflate(R.layout.item_list_joke,parent,false);
            holder = new ViewHolder();
            holder.title = (TextView) convertView.findViewById(R.id.title);
            holder.type = (TextView) convertView.findViewById(R.id.type);
            holder.updatatime = (TextView) convertView.findViewById(R.id.updatatime);
            holder.content = (TextView) convertView.findViewById(R.id.content);

            convertView.setTag(holder);   //将Holder存储到convertView中
        }else{
            holder = (ViewHolder) convertView.getTag();
        }
        holder.title.setText(mData.get(position).getTitle());
        holder.type.setText(mData.get(position).getTitle());
        holder.updatatime.setText(mData.get(position).getTitle());
        holder.content.setText(mData.get(position).getTitle());
        return convertView;
    }

    static class ViewHolder{
        TextView title;
        TextView type;
        TextView updatatime;
        TextView content;
    }

    /**
     * 添加数据
     * */
    public void add(Joke data) {
        if (mData == null) {
            mData = new LinkedList<>();
        }
        mData.add(data);
        notifyDataSetChanged();
    }

    /**
     * 删除数据
     * */
    public void remove(int position) {
        if(mData != null) {
            mData.remove(position);
        }
        notifyDataSetChanged();
    }
}

4、在MainActivity中使用

（1）activity_main.xml中添加listview控件

<ListView
    android:id="@+id/joke_lv"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1">
</ListView>

(2)在MainActivity的oncreat中添加

       

/**
 * 使用列表
 * */
ListView joke_lv = (ListView) view.findViewById(R.id.joke_lv);
List<Joke> mData = new LinkedList<Joke>();

Joke joke1=new Joke();
joke1.setTitle("狼来了");
joke1.setType("经典笑话");
joke1.setUpdatatime("2016.3.1");
joke1.setContent("骗你的，狼没来！哈哈哈！");
mData.add(joke1);

JokeListAdapter mAdapter = new JokeListAdapter((LinkedList<Joke>) mData, this);
joke_lv.setAdapter(mAdapter);

5、运行如图
