android中简单的listview代码

1.主界面布局xml代码

<?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:layout_width="match_parent" android:layout_height="50dp" android:background="#339933" android:gravity="center" android:text="配置设备" android:textColor="#ffffff" android:textSize="20dp" />

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

</LinearLayout>

2.SceneMatchSwitchActivity界面代码

public class SceneMatchSwitchActivity extends Activity {

    private ListView    mLampListview;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // 加载布局
        setContentView(R.layout.activity_scene_match_switches);
        mLampListview = (ListView) findViewById(R.id.smart_control_lamp_listview);
        // listview绑定Adapter
        mLampListview.setAdapter(new myAdapter());

        // 获取服务器反馈回来的设备类型
    }

    private class myAdapter extends BaseAdapter {

        @Override
        public int getCount() {
            // 返回listview的item的总数
            return 7;
        }

        @Override
        public Object getItem(int position) {
            return null;
        }

        @Override
        public long getItemId(int position) {
            return 0;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {

            ViewHolder holder = null;
            if (convertView == null) {
                // 通过布局创建listview的item
                convertView = View.inflate(getApplicationContext(), R.layout.item_bluetooth_device_status, null);
                holder = new ViewHolder();
                convertView.setTag(holder);
                // 给holder找view
                holder.mTextViewDeviceName = (TextView) convertView.findViewById(R.id.bluetooth_device_name_textview);
                holder.mTextViewDeviceState = (TextView) convertView.findViewById(R.id.bluetooth_device_state);
                holder.mTextViewDeviceSwitch = (ImageView) convertView.findViewById(R.id.bluetooth_device_switch_imageview);
                holder.mTextViewDeviceIcon = (ImageView) convertView.findViewById(R.id.bluetooth_device_icon_imageview);
            } else {
                holder = (ViewHolder) convertView.getTag();
            }

            // 给控件设置数据
            // mTextViewPosition.setText("位置 " + position);
            // mTextViewName.setText("姓名 " + position);
            return convertView;
        }

        // holder把item的控件变量集合起来，避免每次加载都再找一次id
        private class ViewHolder {
            TextView    mTextViewDeviceName;    // 设备名字
            TextView    mTextViewDeviceState;   // 设备状态
            ImageView   mTextViewDeviceSwitch;  // 设备打开或者关闭
            ImageView   mTextViewDeviceIcon;    // 设备图片
        }
    }
}

3.listview要加载的item样式：图片以及布局代码

• 布局代码：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_weight="1" android:padding="5dp" >

    <ImageView  android:id="@+id/bluetooth_device_switch_imageview" style="@style/HotelModeSelect_001" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:layout_marginRight="30dp" android:src="@drawable/openguan" />

    <ImageView  android:id="@+id/bluetooth_device_icon_imageview" style="@style/HotelModeSelect_001" android:layout_alignParentLeft="true" android:layout_centerVertical="true" android:layout_marginLeft="9dp" android:src="@drawable/lock_close_icon" />

    <LinearLayout  style="@style/HotelModeSelect_001" android:layout_centerVertical="true" android:layout_marginLeft="16dp" android:layout_toRightOf="@+id/bluetooth_device_icon_imageview" android:orientation="vertical" >

        <TextView  android:id="@+id/bluetooth_device_name_textview" style="@style/HotelModeSelect_001" android:textColor="#000000" android:text="门锁" />

        <LinearLayout  android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="3dp" >

            <TextView  style="@style/HotelModeSelect_001" android:text="状态：" android:textColor="#66000000" android:textSize="10sp" />

            <TextView  android:id="@+id/bluetooth_device_state" style="@style/HotelModeSelect_001" android:text="未上锁" android:textColor="#66000000" android:textSize="10sp" />
        </LinearLayout>
    </LinearLayout>

</RelativeLayout>
