android android 在list view中插入一条广告

当看到这个需求的时候，我是懵逼的，怎么在list view中插入一条广告的数据，如果说给list view添加一个头视图或者是尾视图，这都不是问题，在list view中间添加一个数据，我最开始的思路是，给最下面的list view添加两个头视图，一个是list view，另一个是广告，当运行的时候，发现这种做法并不可行，那就一定会有办法解决的。

于是我们换个思路，两个不同的数据，也就是说就是两种不同的ItemViewType，或许我们可以通过判断type的方式来完成这个功能：

1.首先来写布局文件，很简单，就是一个list view

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.administrator.otherviewinlistview.MainActivity">

<ListView
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>

2.再来看数据实体类：

import java.util.List;

/**
* Created by Administrator on 2017/3/22.
*/

public class Bean {

private List<Data> dataList;
private int num;

public Bean(int num, List<Data> dataList) {
this.num = num;
this.dataList = dataList;
}

public int getNum() {
return num;
}

public void setNum(int num) {
this.num = num;
}

public List<Data> getDataList() {
return dataList;
}

public void setDataList(List<Data> dataList) {
this.dataList = dataList;
}

public static class Data {
private String title;
private String body;

public Data(String title, String body) {
this.title = title;
this.body = body;
}

public Data() {
}

public String getTitle() {
return title;
}

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

public String getBody() {
return body;
}

public void setBody(String body) {
this.body = body;
}
}

}

3.然后在MainActivity中使用：

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.ListView;

import java.util.ArrayList;
import java.util.List;

public class MainActivity extends AppCompatActivity {

private ListView listView;
private MainAdapter mainAdapter;
private Bean bean;

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

listView = (ListView) findViewById(R.id.listView);
mainAdapter = new MainAdapter(this);

List<Bean.Data> list = new ArrayList<>();
for (int i = 0; i < 30; i++) {
Bean.Data data = new Bean.Data("this is title " + i, "this is body " );
list.add(data);
}

for (int i = 0; i < 30; i++) {
bean = new Bean(i, list);
}

mainAdapter.setBean(bean);
listView.setAdapter(mainAdapter);
}
}

4.最重要的是在adapter中做处理：

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.ListView;

import java.util.ArrayList;
import java.util.List;

public class MainActivity extends AppCompatActivity {

private ListView listView;
private MainAdapter mainAdapter;
private Bean bean;

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

listView = (ListView) findViewById(R.id.listView);
mainAdapter = new MainAdapter(this);

List<Bean.Data> list = new ArrayList<>();
for (int i = 0; i < 30; i++) {
Bean.Data data = new Bean.Data("this is title " + i, "this is body " );
list.add(data);
}

for (int i = 0; i < 30; i++) {
bean = new Bean(i, list);
}

mainAdapter.setBean(bean);
listView.setAdapter(mainAdapter);
}
}

5.item_view的布局：

<?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">

<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="8dp"
android:layout_marginTop="2dp"
android:text="标题"
android:textSize="20sp" />

<TextView
android:id="@+id/body"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="200dp"
android:layout_marginTop="2dp"
android:layout_marginBottom="2dp"
android:text="内容"
android:textSize="17sp"
android:textColor="@color/colorPrimaryDark"/>

</LinearLayout>

6.item_view_two的布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="210dp">

<ImageView
android:id="@+id/item_view_two_iv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/headiv"
android:scaleType="fitXY"/>

</LinearLayout>
