我想在我的小部件中添加一个按钮,以便它可以通过按下一个按钮来运行一个功能(更改 APN 并在小部件中显示更改的消息)。实际上,自从我在活动中进行了测试以来,该功能就可以使用。有人知道怎么做吗?谢谢!
问候, 陈比尔
嗯,有几种方法。
例如,您可以在注册的 AppWidgetProvider 中进行类似的操作:
public static String ACTION_WIDGET_RECEIVER = "Action!";
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
R.layout.widget_layout);
Intent active = new Intent(context, ThisClass.class);
active.setAction(ACTION_WIDGET_RECEIVER);
PendingIntent actionPendingIntent = PendingIntent.getBroadcast(context,
0, active, 0);
remoteViews.setOnClickPendingIntent(R.id.button, actionPendingIntent);
appWidgetManager.updateAppWidget(appWidgetIds, remoteViews);
}
@Override
public void onReceive(Context context, Intent intent) {
final String action = intent.getAction();
if (AppWidgetManager.ACTION_APPWIDGET_DELETED.equals(action)) {
final int appWidgetId = intent.getExtras().getInt(
AppWidgetManager.EXTRA_APPWIDGET_ID,
AppWidgetManager.INVALID_APPWIDGET_ID);
if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) {
this.onDeleted(context, new int[] { appWidgetId });
}
} else {
if (intent.getAction().equals(ACTION_WIDGET_RECEIVER)) {
doYourStuff();
super.onReceive(context, intent);
}
}
