Adapter基础讲解－SimpleAdapter使用示例：

SimpleAdapter：简单的Adapter，看似简单，功能强大，下面我们来写个稍微复杂一点的列表布局吧！

运行效果图：



代码实现：

先来编写一个列表项目每一项的布局：

list_item.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="horizontal">

<!-- 定义一个用于显示头像的ImageView -->
<ImageView
android:id="@+id/imgtou"
android:layout_width="64dp"
android:layout_height="64dp"
android:baselineAlignBottom="true"
android:paddingLeft="8dp" />

<!-- 定义一个竖直方向的LinearLayout,把QQ呢称与说说的文本框设置出来 -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">

<TextView
android:id="@+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingLeft="8dp"
android:textColor="#1D1D1C"
android:textSize="20sp" />

<TextView
android:id="@+id/says"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingLeft="8px"
android:textColor="#B4B4B9"
android:textSize="14sp" />

</LinearLayout>

</LinearLayout>

接下来是MainActivity.java:

public class MainActivity extends AppCompatActivity {

private String[] names = new String[]{"B神", "基神", "曹神"};
private String[] says = new String[]{"无形被黑，最为致命", "大神好厉害~", "我将带头日狗~"};
private int[] imgIds = new int[]{R.mipmap.head_icon1, R.mipmap.head_icon2, R.mipmap.head_icon3};

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

List<Map<String, Object>> listitem = new ArrayList<Map<String, Object>>();
for (int i = 0; i < names.length; i++) {
Map<String, Object> showitem = new HashMap<String, Object>();
showitem.put("touxiang", imgIds[i]);
showitem.put("name", names[i]);
showitem.put("says", says[i]);
listitem.add(showitem);
}

//创建一个simpleAdapter
SimpleAdapter myAdapter = new SimpleAdapter(getApplicationContext(), listitem, R.layout.list_item, new String[]{"touxiang", "name", "says"}, new int[]{R.id.imgtou, R.id.name, R.id.says});
ListView listView = (ListView) findViewById(R.id.list_test);
listView.setAdapter(myAdapter);
}
}

好的，上面就是SimpleAdapter的简单用法了，有点意思~
