自定义listview Android

可以跟着创建4个文件，然后复制即可使用。

• 可以参考他人博客：http://daoshud1.iteye.com/blog/1874241

涉及到4部分：

1.activity的布局文件
2.每个Items的布局文件(使用ImageView等自定义控件)
3.自定义的adaptor
4.使用listview的adaptor

具体步骤如下

1.activity的布局文件

activity_option1.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity"
    android:background="#eeeeee">
    <ListView
        android:id="@+id/option_list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">

    </ListView>
</RelativeLayout>

2.每个listview的item的布局文件

option_items.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"
    >
    <ImageView
        android:id="@+id/option_picture"
        android:layout_width="100px"
        android:layout_height="100px"
        />
    <TextView
        android:id="@+id/option_name"
        android:layout_marginLeft="200px"
        android:paddingTop="20px"
        android:textSize="30px"
        android:textColor="#000000"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        />

</LinearLayout>

3.listview的Adaptor

OptionAdapter.java

public class OptionAdapter extends BaseAdapter {

    private List<Map<String, Object>> data;
    private LayoutInflater layoutInflater;
    private Context context;

    public OptionAdapter(Context context, List<Map<String, Object>> data) {
        this.context = context;
        this.data = data;
        this.layoutInflater = LayoutInflater.from(context);
    }

    /**
     * 组件集合，对应list.xml中的控件
     *
     * @author Administrator
     */
    public final class Component {
        public ImageView picture;
        public TextView name;
    }

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

    /**
     * 获得某一位置的数据
     */
    @Override
    public Object getItem(int position) {
        return data.get(position);
    }

    /**
     * 获得唯一标识
     */
    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        Component component = null;
        if (convertView == null) {
            component = new Component();
            //获得组件，实例化组件
            convertView = layoutInflater.inflate(R.layout.option_items, null); //这里是items的布局文件！
            component.picture = (ImageView) convertView.findViewById(R.id.option_picture);
            component.name = (TextView) convertView.findViewById(R.id.option_name);
            convertView.setTag(component);
        } else {
            component = (Component) convertView.getTag();
        }
        //绑定数据

        component.picture.setBackgroundResource((Integer) data.get(position).get("option_picture"));
        component.name.setText((String) data.get(position).get("option_name"));
        return convertView;
    }

}

4.使用listview的activity

OptionActivity1.java

public class OptionActivity1 extends Activity {

    private ListView listView = null;
    List<Map<String, Object>> list = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_option1);//记得获取该acitivty的布局文件
        listView = (ListView) findViewById(R.id.option_list);
        list = getData();
        listView.setAdapter(new OptionAdapter(this, list));

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                if(list.get(position).get("option_name").equals("车载空调"))
                {
                    Intent intentMain = new Intent();
                    intentMain.setClass(OptionActivity1.this, AirerActivity2.class);
                    OptionActivity1.this.startActivity(intentMain);
                }
                else if(list.get(position).get("option_name").equals("家居控制"))
                {
                    Intent intent = new Intent();

                    intent.putExtra("mode", 2);//选择模式：2为蓝牙模式
                    intent.putExtra("account", "");
                    intent.setClass(OptionActivity1.this, ClientMainActivity.class);
                    OptionActivity1.this.startActivity(intent);
                }
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    public List<Map<String, Object>> getData() {
        List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();

        Map<String, Object> map = new HashMap<String, Object>();
        map.put("option_picture", R.drawable.car_airer);
        map.put("option_name", "车载空调");
        list.add(map);

        map = new HashMap<String, Object>();
        map.put("option_picture", R.drawable.car_ihome);
        map.put("option_name", "家居控制");
        list.add(map);

        return list;
    }
}

注意事项：

• 记得在AndroidManifest中给activity注册，防止报错
• 如何确定点击哪个items？
  依据自定义adaptor来确定。
  如下内容是list通过get获取map，然后再map中get获取相应内容

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                if(list.get(position).get("option_name").equals("车载空调"))
                {
                    ；
                }
                else if(list.get(position).get("option_name").equals("家居控制"))
                {
                    ；
                }
            }
        });

如下内容用于向list中存入数据

 public List<Map<String, Object>> getData() {
        List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();

        Map<String, Object> map = new HashMap<String, Object>();
        map.put("option_picture", R.drawable.car_airer);
        map.put("option_name", "车载空调");
        list.add(map);

        return list;
    }
