return this;
}

/**

用的时间就比较简单了

public class MainActivity extends AppCompatActivity {
private ListView mListview;
private ArrayList list = new ArrayList();
private ListBean listBean;
CommonAdapter adapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mListview = (ListView) findViewById(R.id.main_list);

  adapter =   new CommonAdapter(getApplicationContext(), list, R.layout.item_listview) {
        @Override
        public void convert(ViewHolder helper, ListBean item) {
            helper.setText(R.id.tv_title, item.getTitle());
            helper.setText(R.id.tv_describe, item.getContent());
            helper.setText(R.id.tv_time, item.getTime());
            helper.setText(R.id.tv_phone, item.getPhoneNum());


        }
    };

    mListview.setAdapter(adapter);
    add();
}

//写一个方法，专门往listview 添加数据

public void add(){
    for (int i = 0; i < 20; i++) {
        listBean=new ListBean("1","2","3","4");
        list.add(listBean);
    }

    adapter.notifyDataSetChanged();

}

}

---

public class ListBean {

private String title;
private String content;
private String time;
private String phoneNum;

public ListBean(String title, String content, String time, String phoneNum) {
    this.title = title;
    this.content = content;
    this.time = time;
    this.phoneNum = phoneNum;
}

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 getTime() {
    return time;
}

public void setTime(String time) {
    this.time = time;
}

public String getPhoneNum() {
    return phoneNum;
}

public void setPhoneNum(String phoneNum) {
    this.phoneNum = phoneNum;
}

}

这是样式的布局 item_listview
