1. 功能:

 

创建Widget后,若为飞行模式,点击Widget,取消飞行模式,否则设置为飞行模式。在变化过程中有动画效果。

 

2. 实现思想:

对应main.xml布局文件,Widget由三张图片组成,pane上层左边为airplane,右边为switch点击桌面widget时图标的时候,左边airplane四张图标动态的在切换,直到设置为飞行模式或者取消飞行模式状态完成时,airplane切换停止,同时右边switch图片切换settrings_switch_on或者settrings_switch_off。

 

3.       程序中用到图片资源文件如下:

settings_icon_airplane_01.png    

 

 

settings_icon_airplane_02.png    

 

 

 

settings_icon_airplane_03.png    

 

 

settings_icon_airplane_04.png

   

settings_pane_off.png   

 

 

settings_switch_off.png    

 

 

 

settings_switch_on.png     

 

 

 

widget_icon_airplane.png   

 

 

code:

布局文件main.xml

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content">

    <ImageView android:id="@+id/setting_pane"

       android:layout_width="wrap_content"

       android:layout_height="wrap_content"

       android:src="@drawable/settings_pane_off"/>

    <ImageView android:id="@+id/setting_airplane"

           android:layout_width="wrap_content"

           android:layout_height="wrap_content"

           android:layout_alignParentLeft="true"

           android:layout_centerVertical="true"

           android:layout_marginLeft="6dip"

           android:src="@drawable/settings_icon_airplane_04"/>

    <ImageView android:id="@+id/setting_switch"

           android:layout_width="wrap_content"

           android:layout_height="wrap_content"

           android:layout_toRightOf="@id/setting_airplane"

           android:layout_centerVertical="true"

           android:layout_marginLeft="4dip"

           android:src="@drawable/settings_switch_off"/>

</RelativeLayout>

 

在res下新建xml文件夹,然后新建widget_provider.xml

<?xml version="1.0" encoding="UTF-8"?>

<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"

    android:minWidth="50dip" <-指定宽度度->

    android:minHeight="50dip" <-指定高度->

    android:initialLayout="@layout/main"/>

 

新建AirplaneModeEnabler类

public class AirplaneModeEnabler{

//此方法判断是否为飞行模式

 public static boolean isAirplaneModeOn(Context context){

  return Settings.System.getInt(context.getContentResolver(), Settings.System.AIRPLANE_MODE_ON,0)!=0;

 }

//此方法设置或取消飞行模式

 public static void setAirplaneModeOn(Context context,boolean enabling){

  Settings.System.putInt(context.getContentResolver(), Settings.System.AIRPLANE_MODE_ON, enabling?1:0);

  Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);

  intent.putExtra("state", enabling);

  context.sendBroadcast(intent);

 }

}

 

建MyWidget 类,继承AppWidgetProvider

public class MyWidget extends AppWidgetProvider {

 

 private Context mContext = null;

 public RemoteViews remoteViews = new RemoteViews("com.archermind.widget", R.layout.main);

 public final static String SET_AIRPLANE_ACTION = "com.archermind.set_airplane_mode";

 private static final int START_ANIMATION = 0;

 private static final int END_ANIMATION = 1;

 private static Boolean mRunAnimation = false;

 private Handler mHandler = new Handler() {

  @Override

  public void handleMessage(Message msg) {

   if (msg.what == START_ANIMATION) {

    Log.i("state", "START_ANIMATION: mRunAnimation = " + mRunAnimation);

    if (!mRunAnimation) {

     return;

    }

    remoteViews.setImageViewResource(R.id.setting_airplane, mDrawable[msg.arg1]);

    AppWidgetManager appWidgetManger = AppWidgetManager

     .getInstance(mContext);

    int[] appIds = appWidgetManger.getAppWidgetIds(new ComponentName(

            mContext, MyWidget.class));

    for (int id: appIds) {

     appWidgetManger.updateAppWidget(id, remoteViews);

    }

   

    // send message for next frame

    Message message = mHandler.obtainMessage(START_ANIMATION);

    message.arg1 = (msg.arg1 + 1) % 4;

    mHandler.sendMessageDelayed(message, 200);

   } else if (msg.what == END_ANIMATION) {

    Log.i("state", "END_ANIMATION: mRunAnimation = " + mRunAnimation);

    AppWidgetManager appWidgetManger = AppWidgetManager

        .getInstance(mContext);

    int[] appIds = appWidgetManger.getAppWidgetIds(new ComponentName(

           mContext, MyWidget.class));

    for (int id: appIds) {

     updateAppWidget(mContext, appWidgetManger, id);

    }

   }

   Log.i("hThreadId",Long.toString(Thread.currentThread().getId()));

  }

 };

 

 private int[] mDrawable = {

  R.drawable.settings_icon_airplane_01,

  R.drawable.settings_icon_airplane_02,

  R.drawable.settings_icon_airplane_03,

  R.drawable.settings_icon_airplane_04

 @Override

   boolean airplaneMode = AirplaneModeEnabler.isAirplaneModeOn(context);

   if(airplaneMode){

          AirplaneModeEnabler.setAirplaneModeOn(context, !airplaneMode);

   Log.e("state", "onReceive: mRunAnimation = true");

   mRunAnimation = true;

   Message msg = mHandler.obtainMessage(START_ANIMATION);

   msg.arg1 = 0;

   mHandler.sendMessage(msg);

  }

 }

 

 @Override

 public void onUpdate(Context context, AppWidgetManager appWidgetManager,

   int[] appWidgetIds) {

  super.onUpdate(context, appWidgetManager, appWidgetIds);

  Log.i("method", "onUpdate()");

  if(mContext==null){

   mContext = context;

  }

  remoteViews = new RemoteViews(context.getPackageName(), R.layout.main);

  int n = appWidgetIds.length;

     for (int i = 0; i < n; i++) {

        int appWidgetId = appWidgetIds[i];

        updateAppWidget(context, appWidgetManager, appWidgetId);

            AppWidgetManager appWidgeManger, int appWidgetId) {
