Android小部件的两个按钮以不同的意图调用相同的Activity

Question

我在Android中有一个带有两个按钮的homescreenwidget.两个按钮都应该调用相同的活动(类),只需使用不同的intent和intent附加功能,以了解哪个按钮称为类.现在只有button1工作并调用活动.我还在被调用的Activity中收到keyvalue.

如何让第二个按钮工作？这是我的代码:

             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);

这是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你创建了2个PendingIntent ......

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

其中PendingIntent.getActivity(Context context,int requestCode,Intent intent,int flags)有4个参数.您必须为不同的PendingIntents 发送不同的" requestCode ".

你的代码应该是......

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

在主类中你需要创建这个...

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);

}

使用onUpdate代码....

    @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);
    }
}

然后你可以检查value = 1st Button或value = 2nd Button来知道单击了哪个Button.它应该工作......如果它不起作用,请让我知道问题是什么...
