Android小部件的兩個按鈕調用相同的活動有不同的意圖

Question

我有一個Android的homescreenwidget有兩個按鈕。兩個按鈕都應該調用相同的活動（類），只需使用不同的意圖和意圖附加功能，即可知道哪個按鈕稱爲類。 現在只有button1正在工作並調用活動。我還會在被調用的活動中收到關鍵值。

我怎樣才能使第二個按鈕的工作？ 這裏是我的代碼：

   public void onUpdate(Context context, AppWidgetManager appWidgetManager, 
     int[] appWidgetIds) { 

    super.onUpdate(context, appWidgetManager, appWidgetIds); 

    for (int i =0; i<appWidgetIds.length ; i++){ 

     int appWidgetId = appWidgetIds[i]; 

     Intent intent2 = new Intent(context, Main.class); 
     Intent intent1 = new Intent(context, Main.class); 

     // Intent put extras Button 1 
     String bread1 = "secure"; 
     Bundle basket1 = new Bundle(); 
     basket1.putString("key", bread1); 
     intent1.putExtras(basket1); 

     // Intent put extras Button 2 
     String bread2 = "insecure"; 
     Bundle basket2 = new Bundle(); 
     basket2.putString("key", bread2); 
     intent2.putExtras(basket2); 

     PendingIntent pending1 = PendingIntent.getActivity(context,0,intent1, 0); 
     PendingIntent pending2 = PendingIntent.getActivity(context, 0, intent2, 0); 

     RemoteViews views1 = new RemoteViews(context.getPackageName(),R.layout.maina); 
     RemoteViews views2 = new RemoteViews(context.getPackageName(),R.layout.maina); 

     views1.setOnClickPendingIntent(R.id.button1, pending1); 
     views2.setOnClickPendingIntent(R.id.button2, pending2); 

     appWidgetManager.updateAppWidget(appWidgetId, views1); 
     appWidgetManager.updateAppWidget(appWidgetId, views2); 

這裏是maina.xml

  <?xml version="1.0" encoding="utf-8"?> 
      <LinearLayout 
      xmlns:android="http://schemas.android.com/apk/res/android" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent" android:weightSum="1"    android:orientation="vertical"> 
      <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TextView" android:id="@+id/tvWidget" android:textAppearance="?android:attr/textAppearanceLarge"></TextView> 

      <LinearLayout 
      xmlns:android="http://schemas.android.com/apk/res/android" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent" android:weightSum="1" android:orientation="horizontal"> 



      <Button android:text="@string/button1" android:id="@+id/button1" android:layout_height="wrap_content" android:layout_width="wrap_content"></Button> 
      <Button android:text="@string/button2" android:id="@+id/button2" android:layout_height="wrap_content" android:layout_width="wrap_content"></Button> 

      </LinearLayout> 

</LinearLayout>

@Arnold已創建2的PendingIntent這是....

PendingIntent pending1 = PendingIntent.getActivity(context,0,intent1, 0); 
PendingIntent pending2 = PendingIntent.getActivity(context, 0, intent2, 0); 

凡PendingIntent.getActivity（上下文的背景下，INT requestCode，意圖意圖，詮釋標誌）有4個參數。您必須爲不同的PendingIntents發送不同的「requestCode」。

你的代碼應該是....

PendingIntent pending1 = PendingIntent.getActivity(context,0,intent1, PendingIntent.FLAG_UPDATE_CURRENT); 
PendingIntent pending2 = PendingIntent.getActivity(context, 1, intent2, PendingIntent.FLAG_UPDATE_CURRENT); 

在您需要創建這個主類

...

String value; 
@Override 
public void onReceive(Context context, Intent intent) { 
    // TODO Auto-generated method stub 

      Bundle b=intent.getExtras(); 


    try{ 
    value=b.getString("key"); 
    } 
    catch (Exception e) { 
     // TODO: handle exception 
    } 

    super.onReceive(context, intent); 

} 

用的onUpdate代碼....

@Override 
public void onUpdate(Context context, AppWidgetManager appWidgetManager, 
     int[] appWidgetIds) { 

    // Get all ids 
    ComponentName thisWidget = new ComponentName(context, 
      main.class); 
    int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget); 

    for (int widgetId : allWidgetIds) { 
     // Create some random data 

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


     // Register an onClickListener for 1st button 
     Intent intent = new Intent(context, main.class); 

     intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE); 
     intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS,allWidgetIds); 
     intent.putExtra("key", "1st Button"); 

     PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 
       0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 

     remoteViews.setOnClickPendingIntent(R.id.button1, pendingIntent); 

     // Register an onClickListener for 2nd button............ 
     Intent intent2 = new Intent(context, main.class); 

      intent2.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE); 
        intent2.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS,allWidgetIds); 
      intent2.putExtra("key", "2nd Button"); 

     PendingIntent pendingIntent2 = PendingIntent.getBroadcast(context, 
       1, intent2, PendingIntent.FLAG_UPDATE_CURRENT); 

     remoteViews.setOnClickPendingIntent(R.id.button2, pendingIntent2); 

     appWidgetManager.updateAppWidget(widgetId, remoteViews); 
    } 
} 

然後你可以檢查value = 1st Button或valu e =第二個按鈕瞭解哪個Button已被點擊。 它應該工作...如果它不能正常工作，請讓我知道是什麼問題...

小部件只會有1個遠程視圖。試着改變你的代碼段的末尾：

RemoteViews remoteView = new RemoteViews(context.getPackageName(),R.layout.maina); 

remoteView.setOnClickPendingIntent(R.id.button1, pending1); 
remoteView.setOnClickPendingIntent(R.id.button2, pending2); 

appWidgetManager.updateAppWidget(appWidgetId, remoteView); 

做不到這一點，這將是看你的佈局R.layout.maina有用。

Answer 3

我在使用widget上的2個按鈕時遇到了類似的問題。我在它們上設置了OnClickPendingIntents，並通過不同的setExtra（）調用進行區分。但只有後者的意圖被稱爲，即使點擊第一個按鈕。 我發現2個解決方案： - 分配不同的行動，既PendingIntents - 第二PendingEvent設置PendingEvent.FLAG_CANCEL_CURRENT標誌

我與PendingEvents和窗口小部件很陌生，所以我不能看到利弊，將堅持第一個解決方案。

也許這可能會幫助你解決你的問題。

Answer 4

在我的情況：

remoteViews.setOnClickPendingIntent(R.id.widget_head, touch_man(context)); 

remoteViews.setOnClickPendingIntent（R.id。widget_head2，touch_woman（context））;

public static PendingIntent touch_man(Context context) { 

    Intent intent = new Intent(); 
    intent.setAction("touch_man"); 
    return PendingIntent.getBroadcast(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 

} 

public static PendingIntent touch_woman(Context context) { 

    Intent intent = new Intent(); 
    intent.setAction("touch_woman"); 
    return PendingIntent.getBroadcast(context, 1, intent, PendingIntent.FLAG_UPDATE_CURRENT); 

} 

在AndroidManifest

<receiver 
     android:name="Receiver" 
     android:label="widgetBroadcastReceiver" > 
     <intent-filter> 
      <action android:name="touch_man" /> 
      <action android:name="touch_woman"/> 
     </intent-filter> 

     <meta-data 
      android:name="android.appwidget.provider" 
      android:resource="@xml/demo_widget_provider" /> 
    </receiver> 

它的工作。
