The key must be an application-specific resource id 就是前面这个要唯一,定义一个final类型的int变量和硬编码一个值的方式都是行不通的 这里的做法是直接在strings.xml中添加:

<item name="Tag_APP" type="id"></item>
<item name="Tag_Book" type="id"></item>
MainActivity.java:

public class MainActivity extends AppCompatActivity {

    private static final int TYPE_BOOK = 0;
    private static final int TYPE_APP = 1;
    private ListView list_content;
    private ArrayList<Object> mData = null;
    private MutiLayoutAdapter myAdapter = null;

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

        //数据准备:
        mData = new ArrayList<Object>();
        for(int i = 0;i < 20;i++){
            switch ((int)(Math.random() * 2)){
                case TYPE_BOOK:
                    mData.add(new Book("《第一行代码》","郭霖"));
                    break;
                case TYPE_APP:
                    mData.add(new App(R.mipmap.iv_icon_baidu,"百度"));
                    break;
            }
        }

        list_content = (ListView) findViewById(R.id.list_content);
        myAdapter = new MutiLayoutAdapter(MainActivity.this,mData);
        list_content.setAdapter(myAdapter);
    }
}
上面随机生成0和1,0就往集合中添加一个Book的对象,1的话就添加一个App的对象!
