在Android小部件上处理多个按钮点击
在Android小部件上处理多个按钮点击
提问于 2010-03-19 01:09:42
我按照描述的那样saw this topic并实现了IntentService，但是如果我想要多个按钮怎么办？如何区分按钮？我正在尝试setFlags，但无法在onHandleIntent()方法中读取它：
public static class UpdateService extends IntentService {
...
@Override
public void onHandleIntent(Intent intent) {
ComponentName me = new ComponentName(this, ExampleProvider.class);
AppWidgetManager manager = AppWidgetManager.getInstance(this);
manager.updateAppWidget(me, buildUpdate(this));
}
private RemoteViews buildUpdate(Context context) {
RemoteViews updateViews = new RemoteViews(context.getPackageName(), R.layout.main_layout);
Intent i = new Intent(this, ExampleProvider.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0);
updateViews.setOnClickPendingIntent(R.id.button_refresh, pi);
i = new Intent(this, ExampleProvider.class);
pi = PendingIntent.getBroadcast(context, 0, i, 0);
updateViews.setOnClickPendingIntent(R.id.button_about, pi);
return updateViews;
}
}在这一小段代码中，我有两个与setOnClickPendingIntent链接的PendingIntent，我能区分不同操作和处理的意图吗？感谢你的帮助

这就是扩展AppWidgetProvider的Widget类：
public class ExampleProvider extends AppWidgetProvider {
// our actions for our buttons
public static String ACTION_WIDGET_REFRESH = "ActionReceiverRefresh";
public static String ACTION_WIDGET_SETTINGS = "ActionReceiverSettings";
public static String ACTION_WIDGET_ABOUT = "ActionReceiverAbout";
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.main_layout);
Intent active = new Intent(context, ExampleProvider.class);
active.setAction(ACTION_WIDGET_REFRESH);
PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);
remoteViews.setOnClickPendingIntent(R.id.button_refresh, actionPendingIntent);
active = new Intent(context, ExampleProvider.class);
active.setAction(ACTION_WIDGET_SETTINGS);
actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);
remoteViews.setOnClickPendingIntent(R.id.button_settings, actionPendingIntent);
active = new Intent(context, ExampleProvider.class);
active.setAction(ACTION_WIDGET_ABOUT);
actionPendingIntent = PendingIntent.getBroadcast(context, 0, active, 0);
remoteViews.setOnClickPendingIntent(R.id.button_about, actionPendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
}
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ACTION_WIDGET_REFRESH)) {
Log.i("onReceive", ACTION_WIDGET_REFRESH);
} else if (intent.getAction().equals(ACTION_WIDGET_SETTINGS)) {
Log.i("onReceive", ACTION_WIDGET_SETTINGS);
} else if (intent.getAction().equals(ACTION_WIDGET_ABOUT)) {
Log.i("onReceive", ACTION_WIDGET_ABOUT);
} else {
super.onReceive(context, intent);
}
}
...和AndroidManifest.xml，我们必须在其中注册我们的操作：
<receiver android:name="ExampleProvider">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE"/>
<action android:name="org.divenvrsk.widgets.ExampleProvider.ACTION_WIDGET_REFRESH"/>
<action android:name="org.divenvrsk.widgets.ExampleProvider.ACTION_WIDGET_SETTINGS"/>
<action android:name="org.divenvrsk.widgets.ExampleProvider.ACTION_WIDGET_ABOUT"/>
</intent-filter>
<meta-data android:name="android.appwidget.provider" android:resource="@xml/widget_info"/>
</receiver>
</application>
