Android Widget - 点击操作，在30分钟内更新，单独的实例 [英] Android Widget - Click for action, update under 30 minutes, separate instances

问题描述

我试图创建一个小部件，在点击调用一个例行的配置活动上，更新调用另一个例行配置活动，更新必须在30分钟以下，创建的所有实例必须单独工作（在onUpdate和onClick）。

下面的代码：点击不起作用（看不到Toast消息和其他功能）
更新适用于第一个实例，但是多个小部件实例，它的工作不好：
如果我在10秒之间创建2个实例（刷新设置为20秒），每10秒钟就会更新一次。

这是我的清单：

解决方案

对于30分钟以内的多个实例，我决定对所有实例使用一个计时器。

在配置类的创建代码下面：

  private static long millis = 20000; 
 
 SharedPreferences read = context.getSharedPreferences（PREFS_NAME，0）; 
 String firstinstance = read.getString（FirstInstance，KO）; 
 if（firstinstance.equals（KO））{
 SharedPreferences.Editor write = context.getSharedPreferences（
 PREFS_NAME，0）.edit（）; 
 write.putString（FirstInstance，OK）; 
 write.commit（）; 
 Intent intent = new Intent（ControlloWidget.MY_WIDGET_UPDATE）; 
 PendingIntent pendingIntent = PendingIntent.getBroadcast（
 Configurazione.this，0，intent，0）; 
 AlarmManager alarmManager =（AlarmManager）getSystemService（ALARM_SERVICE）; 
日历calendar = Calendar.getInstance（）; 
 calendar.setTimeInMillis（System.currentTimeMillis（））; 
 calendar.add（Calendar.SECOND，10）; 
 alarmManager.setRepeating（AlarmManager.RTC_WAKEUP，
 calendar.getTimeInMillis（），millis，pendingIntent）; 
 ControlloWidget.SaveAlarmManager（alarmManager，pendingIntent）; 
} 
  

将该进程恢复为WidgetClassDisabled：

  @Override 
 public void onDisabled（Context context）{
 // TODO自动生成的方法存根
 //super.onDisabled （上下文）; 
 SharedPreferences.Editor write = context.getSharedPreferences（PREFS_NAME，0）.edit（）; 
 write.putString（FirstInstance，KO）; 
 write.commit（）; 
 myAlarmManager.cancel（myPendingIntent）; 
} 
 static void SaveAlarmManager（AlarmManager tAlarmManager，PendingIntent tPendingIntent）{
 myAlarmManager = tAlarmManager; 
 myPendingIntent = tPendingIntent; 
} 
  

现在，设置按钮操作和我自己的更新：
类声明：

  public static String ACTION_WIDGET_CLICKED =your.packagename.ACTION_WIDGET_CLICKED; 
 public static String MY_WIDGET_UPDATE =your.packagename.MY_WIDGET_UPDATE; 
  

onReceive方法：

  @Override 
 public void onReceive（Context context，Intent intent）{
 // TODO自动生成的方法stub 
 super.onReceive（context，intent）; 
 choice = false; 
 // ////Toast.makeText(context，intent.getAction（），
 // //// Toast.LENGTH_LONG）.show（）; 
 // choice = false; 
 
 Bundle extras = intent.getExtras（）; 
 
 if（MY_WIDGET_UPDATE.equals（intent.getAction（）））{
 choice = false; 
 
 AppWidgetManager appWidgetManager = AppWidgetManager 
 .getInstance（context）; 
 ComponentName thisAppWidget = new ComponentName（
 context.getPackageName（），ControlloWidget.class.getName（））; 
 int [] appWidgetIds = appWidgetManager 
 .getAppWidgetIds（thisAppWidget）; 
 
 onUpdate（上下文，appWidgetManager，appWidgetIds）; 
 // ////Toast.makeText(context，AUTOUPDATE，
 // //// Toast.LENGTH_LONG）.show（）; 
} else 
 
 if（ACTION_WIDGET_CLICKED.equals（intent.getAction（）））{
 // choice = true; 
 AppWidgetManager appWidgetManager = AppWidgetManager 
 .getInstance（context）; 
 ComponentName thisAppWidget = new ComponentName（
 context.getPackageName（），ControlloWidget.class.getName（））; 
 int [] appWidgetIds = appWidgetManager 
 .getAppWidgetIds（thisAppWidget）; 
 int appWidgetId = intent.getIntExtra（
 AppWidgetManager.EXTRA_APPWIDGET_ID，-1）; 
 // //////// 
 RemoteViews remoteViews = new RemoteViews（context.getPackageName（），
 R.layout.widget）; 
 remoteViews.setTextViewText（R.id.btnEsegui，
 Configurazione.getName（context，nome，appWidgetId））; 
 
 // ACTION CODE HERE 
 appWidgetManager.updateAppWidget（appWidgetId，remoteViews）; 
 Log.d（LOG_Esecuzione，
Log Esecuzione，Widget n。+ String.valueOf（appWidgetId））; 
 
} 
 
} 
  

然后onUpdate和updateAppWidget方法：

  @Override 
 public void onUpdate（Context context，AppWidgetManager appWidgetManager，
 int [] appWidgetIds）{
 // TODO自动生成的方法stub 
 // super.onUpdate（context，appWidgetManager，appWidgetIds）; 
 final int N = appWidgetIds.length; （int i = 0; i< N; i ++）
 {
 int appWidgetId = appWidgetIds [i]; 
 updateAppWidget（context，appWidgetManager，appWidgetId）; 
} 
} 
 
 public static void updateAppWidget（Context context，AppWidgetManager appWidgetManager，int appWidgetId）{
 // TestOnClick 
 
 RemoteViews remoteViews = new RemoteViews（context.getPackageName（），R.layout.widget）; 
 Intent myIntent = new Intent（context，ControlloWidget.class）; 
 myIntent.setAction（ACTION_WIDGET_CLICKED）; 
 myIntent.putExtra（AppWidgetManager.EXTRA_APPWIDGET_ID，appWidgetId）; 
 PendingIntent pendingIntent = PendingIntent.getBroadcast（context，appWidgetId，
 myIntent，0）; 
 remoteViews.setOnClickPendingIntent（R.id.btnEsegui，pendingIntent）; 
 remoteViews.setTextViewText（R.id.btnEsegui，Configurazione.getName（context，nome，appWidgetId））; 
 //在更新代码中，当调用onUpdate（对于所有窗口小部件）时，请求的Action都会刷新挂起的意图
 
 appWidgetManager.updateAppWidget（appWidgetId，remoteViews）; 
 Log.d（LOG_UPDATE，日志更新，Widget n。+ String.valueOf（appWidgetId））; 
} 
 appWidgetManager.updateAppWidget（appWidgetId，remoteViews）; 
} 
  

需要单独的实例：

意图创建：（在updateAppWidget上）

  RemoteViews remoteViews = new RemoteViews（context.getPackageName（），R。 layout.widget）; 
 Intent myIntent = new Intent（context，ControlloWidget.class）; 
 myIntent.setAction（ACTION_WIDGET_CLICKED）; 
 //下面的行是appWidgetId规范
 myIntent.putExtra（AppWidgetManager.EXTRA_APPWIDGET_ID，appWidgetId）; 
 PendingIntent pendingIntent = PendingIntent.getBroadcast（context，appWidgetId，
 myIntent，0）; 
 remoteViews.setOnClickPendingIntent（R.id.btnEsegui，pendingIntent）; 
  

收到广播时：（on onReceive）

  if（ACTION_WIDGET_CLICKED.equals（intent.getAction（）））{
 //在该示例中未使用注释
 // AppWidgetManager appWidgetManager = AppWidgetManager.getInstance （上下文）; 
 // ComponentName thisAppWidget = new ComponentName（context.getPackageName（），ControlloWidget.class.getName（））; 
 // int [] appWidgetIds = appWidgetManager.getAppWidgetIds（thisAppWidget）; 
 int appWidgetId = intent.getIntExtra（AppWidgetManager.EXTRA_APPWIDGET_ID，-1）; 
  

现在我们可以调用任何程序遍历appWidgetId和Context来运行...
示例：

  Action.SomeAction（context，appWidgetId）; 
 

对于UPDATE TIMER，也可以（不使用首选项）：
喜欢其他意图
可以使用 putExtra
然后播放：
检索广播接收的int

int $ {code> int appWidgetId = intent.getIntExtra（AppWidgetManager.EXTRA_APPWIDGET_ID，-1）;但是现在我们不调用 onUpdate

方法，但直接 updateAppWidget
与该替代解决方案每个小部件都有自己的时间刷新（可配置）
我更喜欢只有一个定时器进程在同一时间激活，并获得所有的窗口小部件更新在第一个实例小部件更新时间

I've tried to create a widget that, on click calls a routine on Configuration activity, on update calls another routine on Configuration activity, update must be under 30 minutes and all the instance created must work separately (in onUpdate and in onClick).

The code below: Click doesn't work (Can't See Toast Message and other function) Update works fine for first instance but with multiple widget instance it works bad: If i create 2 instances between 10 seconds (and refresh is set to 20 seconds) all will update every 10 seconds.

That's my Manifest:

解决方案

For Timing under 30 mins and multiple instances i've decided to use only one timer for all instances.

Below the code onCreate of Configuration Class:

private static long millis = 20000;

SharedPreferences read = context.getSharedPreferences(PREFS_NAME, 0);
String firstinstance = read.getString("FirstInstance", "KO");
if (firstinstance.equals("KO")) {
    SharedPreferences.Editor write = context.getSharedPreferences(
            PREFS_NAME, 0).edit();
    write.putString("FirstInstance", "OK");
    write.commit();
    Intent intent = new Intent(ControlloWidget.MY_WIDGET_UPDATE);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(
            Configurazione.this, 0, intent, 0);
    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());
    calendar.add(Calendar.SECOND, 10);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
            calendar.getTimeInMillis(), millis, pendingIntent);
    ControlloWidget.SaveAlarmManager(alarmManager, pendingIntent);
}

revert that process onDisabled of WidgetClass:

@Override
public void onDisabled(Context context) {
    // TODO Auto-generated method stub
    //super.onDisabled(context);
    SharedPreferences.Editor write = context.getSharedPreferences(PREFS_NAME, 0).edit();    
    write.putString("FirstInstance", "KO" );    
    write.commit();
    myAlarmManager.cancel(myPendingIntent);
}
static void SaveAlarmManager(AlarmManager tAlarmManager, PendingIntent tPendingIntent){
    myAlarmManager = tAlarmManager;
    myPendingIntent = tPendingIntent;
}

Now, setting up button Action and My Own Update: Class declaration:

public static String ACTION_WIDGET_CLICKED = "your.packagename.ACTION_WIDGET_CLICKED";
public static String MY_WIDGET_UPDATE = "your.packagename.MY_WIDGET_UPDATE";

onReceive method:

@Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    super.onReceive(context, intent);
    choice = false;
    // ////Toast.makeText(context, intent.getAction(),
    // ////Toast.LENGTH_LONG).show();
    // choice=false;

    Bundle extras = intent.getExtras();

    if (MY_WIDGET_UPDATE.equals(intent.getAction())) {
        choice = false;

        AppWidgetManager appWidgetManager = AppWidgetManager
                .getInstance(context);
        ComponentName thisAppWidget = new ComponentName(
                context.getPackageName(), ControlloWidget.class.getName());
        int[] appWidgetIds = appWidgetManager
                .getAppWidgetIds(thisAppWidget);

        onUpdate(context, appWidgetManager, appWidgetIds);
        // ////Toast.makeText(context, "AUTOUPDATE",
        // ////Toast.LENGTH_LONG).show();
    } else

    if (ACTION_WIDGET_CLICKED.equals(intent.getAction())) {
        // choice =true;
        AppWidgetManager appWidgetManager = AppWidgetManager
                .getInstance(context);
        ComponentName thisAppWidget = new ComponentName(
                context.getPackageName(), ControlloWidget.class.getName());
        int[] appWidgetIds = appWidgetManager
                .getAppWidgetIds(thisAppWidget);
        int appWidgetId = intent.getIntExtra(
                AppWidgetManager.EXTRA_APPWIDGET_ID, -1);
        // ////////
        RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
                R.layout.widget);
        remoteViews.setTextViewText(R.id.btnEsegui,
                Configurazione.getName(context, "nome", appWidgetId));

        // ACTION CODE HERE
        appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
        Log.d("LOG_Esecuzione",
                "Log Esecuzione, Widget n." + String.valueOf(appWidgetId));

    }

}

Then onUpdate and updateAppWidget Method:

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
        int[] appWidgetIds) {
    // TODO Auto-generated method stub
    // super.onUpdate(context, appWidgetManager, appWidgetIds);
    final int N = appWidgetIds.length;
    for (int i = 0; i < N; i++) {
        int appWidgetId = appWidgetIds[i];
        updateAppWidget(context, appWidgetManager, appWidgetId);
    }
}

public static void updateAppWidget(Context context, AppWidgetManager appWidgetManager,int appWidgetId){
    //TestOnClick

    RemoteViews remoteViews = new RemoteViews(context.getPackageName(),R.layout.widget);
    Intent myIntent = new Intent(context, ControlloWidget.class);
    myIntent.setAction(ACTION_WIDGET_CLICKED);
    myIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context,appWidgetId,
            myIntent, 0);
    remoteViews.setOnClickPendingIntent(R.id.btnEsegui, pendingIntent);
    remoteViews.setTextViewText(R.id.btnEsegui,Configurazione.getName(context, "nome", appWidgetId));
    //On Update Code, Requested Action when onUpdate is called (for all widget), it also refresh pending intent                     

    appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
    Log.d("LOG_UPDATE", "Log Update, Widget n."+String.valueOf(appWidgetId));
                                }
    appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
}

For separate instances is necessary:

On intentcreation:(on updateAppWidget)

RemoteViews remoteViews = new RemoteViews(context.getPackageName(),R.layout.widget);
Intent myIntent = new Intent(context, ControlloWidget.class);
myIntent.setAction(ACTION_WIDGET_CLICKED);
            //The line below is the appWidgetId Specification
myIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context,appWidgetId,
        myIntent, 0);
remoteViews.setOnClickPendingIntent(R.id.btnEsegui, pendingIntent);

On receiving broadcast: (on onReceive)

if (ACTION_WIDGET_CLICKED.equals(intent.getAction())){
    //Commented are not used on that example
    //AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
    //ComponentName thisAppWidget = new ComponentName(context.getPackageName(), ControlloWidget.class.getName());
    //int[] appWidgetIds = appWidgetManager.getAppWidgetIds(thisAppWidget);
    int appWidgetId = intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, -1);

now we could call any routine everywhere passing appWidgetId and Context to function... Example:

Action.SomeAction(context,appWidgetId);

For UPDATE TIMER, is also possible (without using preferences): Like the other intent could use putExtra then on broadcast: retrieve the int on broadcast receive

int appWidgetId = intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, -1);

BUT now we don't call onUpdate method but directly updateAppWidget with that alternative solution every widget has his own time refresh (maybe configurable) I've preferred to have only one timer process active at same time and get all the widget updated at first instance widget update time
