处理小部件内的多个按钮 - Android

Question

我有一个显示简单文本和 3 个按钮的小部件：

刷新（选择另一个随机字符串并显示）
Copy（将textview的内容复制到剪贴板）
Share（将textview的内容分享到社交媒体等）

我已经设置了刷新按钮并且工作正常，但我似乎无法找到处理其他两个按钮的方法

PS. 我不需要实际代码我已经知道如何进行复制和共享我只需要知道如何 处理点击事件

到目前为止，这是我的代码：

Button copy_content;
Button share_content;

void updateAppWidget(Context context, AppWidgetManager appWidgetManager, int appWidgetId) {
    /** Code below will be executed once the timer is over*/
    String widgetText = RandQuotes[rand.nextInt(RandQuotes.length)];

    // Construct the RemoteViews object
    RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.quotes_widget);
    views.setTextViewText(R.id.sayings, widgetText);



    // Instruct the widget manager to update the widget
    appWidgetManager.updateAppWidget(appWidgetId, views);
}

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    // There may be multiple widgets active, so update all of them
    for (int appWidgetId : appWidgetIds) {
        updateAppWidget(context, appWidgetManager, appWidgetId);
    }
    final int count = appWidgetIds.length;

    for (int i = 0; i < count; i++) {
        int widgetId = appWidgetIds[i];
        String on_sayings = RandQuotes[rand.nextInt(RandQuotes.length)];

        RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
                R.layout.quotes_widget);
        remoteViews.setTextViewText(R.id.sayings, on_sayings);

        Intent intent = new Intent(context, HavamalWidget.class);
        intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
        intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context,
                0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
        remoteViews.setOnClickPendingIntent(R.id.switch_trigger, pendingIntent);
        appWidgetManager.updateAppWidget(widgetId, remoteViews);
    }

}

只需在带有操作的按钮上创建待定意图。所以在 onReceive() 中只需检查意图的动作并对其进行一些逻辑处理。如果你做一些长任务，最好把所有的逻辑都放在 IntentService 中。

像这样在 RemoteViews 中的按钮上设置待定意图：

public static final String ACTION_BUTTON_SHARE = "ACTION_BUTTON_SHARE";
public static final String ACTION_BUTTON_REFRESH = "ACTION_BUTTON_REFRESH";

Intent refreshIntent = new Intent(context, ExampleAppWidget.class)
            .setAction(ACTION_BUTTON_REFRESH);
PendingIntent refreshPI = PendingIntent.getBroadcast(context, 0, refreshIntent,
            PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.refresh_button, refreshPI);

Intent shareIntent = new Intent(context, ExampleAppWidget.class)
            .setAction(ACTION_BUTTON_SHARE);
PendingIntent sharePI = PendingIntent.getBroadcast(context, 0, shareIntent,
            PendingIntent.FLAG_UPDATE_CURRENT);
remoteViews.setOnClickPendingIntent(R.id.share_button, sharePI);

在 ExampleAppWidget.class 中（从 AppWidgetProvider 扩展）覆盖 OnReceive() 方法

@Override
public void onReceive(Context context, Intent intent) {
    if (intent != null) {
        if (intent.getAction().equals(ACTION_BUTTON_REFRESH)) {
           //make some logic here on button refresh
        } else if (intent.getAction().equals(ACTION_BUTTON_SHARE)) {
           //make some logic here on button share
        } else {
           super.onReceive(context, intent);
        }
    }
}
