如何解决调用 Android updateAppWidget 但未更新小部件或到达 RemoteViewsFactory?
我的应用小部件(显示游戏分数的 ListView)在主屏幕上创建时运行良好,但是当我在提供程序内部调用 appWidgetManager.updateAppWidget(id,R.id.appwidget)
时,小部件或 {{1} 中的日志调用没有反应}} 的 RemoteViewsFactory
或 onCreate()
方法。我知道 onDataSetChanged()
会被调用,因为我可以在它之前看到日志调用。
为什么小部件没有更新?
updateAppWidget
我的 RemoteViewsService 和 RemoteViewsFactory:
class scoresappwidgetprovider : appwidgetprovider() {
override fun onUpdate(context: Context,appWidgetManager: AppWidgetManager,appWidgetIds: IntArray) {
updateallWidgets(appWidgetIds,context,appWidgetManager)
super.onUpdate(context,appWidgetManager,appWidgetIds)
}
private fun updateallWidgets(appWidgetIds: IntArray,context: Context,appWidgetManager: AppWidgetManager) {
appWidgetIds.forEach { appWidgetId ->
updateWidget(appWidgetId,false)
}
}
override fun onReceive(context: Context,intent: Intent) {
super.onReceive(context,intent)
Log.i("TAG","onReceive appWidgetId $appWidgetId") // This is logged and id is correct
if (intent.action.equals(ACTION_CLICK_REFRESH)) {
appWidgetManager.notifyAppWidgetViewDataChanged(appWidgetId,R.id.appwidget_list_view) // Works fine and updates the widget list
} else if (intent.action.equals((ACTION_CLICK_SPOILERS_ON))) { // This is received
updateWidget(appWidgetId,true)
} else if (intent.action.equals((ACTION_CLICK_SPOILERS_OFF))) { // This is received
updateWidget(appWidgetId,false)
}
}
private fun updateWidget(appWidgetId: Int,spoilers: Boolean) {
val intent = Intent(context,AppWidgetService::class.java).apply {
putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,appWidgetId)
putExtra("testString","Intent received")
data = Uri.parse(toUri(Intent.URI_INTENT_SCHEME))
}
// PendingIntent to refresh the appWidget contents
val pendingRefreshClickIntent: PendingIntent = Intent(context,scoresappwidgetprovider::class.java).let {
it.action = scoresappwidgetprovider.ACTION_CLICK_REFRESH
it.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,appWidgetId)
return@let PendingIntent.getbroadcast(context,appWidgetId,it,PendingIntent.FLAG_UPDATE_CURRENT)
}
// PendingIntent to toggle score spoilers
val pendingSpoilersClickIntent: PendingIntent = Intent(context,scoresappwidgetprovider::class.java).let {
it.action = if (spoilers) scoresappwidgetprovider.ACTION_CLICK_SPOILERS_ON else scoresappwidgetprovider.ACTION_CLICK_SPOILERS_ON
it.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,PendingIntent.FLAG_UPDATE_CURRENT)
}
// RemoteViews object for the app widget layout
val remoteViews = RemoteViews(context.packageName,R.layout.appwidget).apply {
if (spoilers) {
setimageViewResource(R.id.btn_spoilers,R.drawable.avd_anim_turn_off_spoilers)
} else {
setimageViewResource(R.id.btn_spoilers,R.drawable.avd_anim_turn_on_spoilers)
}
setRemoteAdapter(R.id.appwidget_list_view,intent)
setEmptyView(R.id.appwidget_list_view,R.id.empty_view)
setonClickPendingIntent(R.id.btn_refresh,pendingRefreshClickIntent)
setonClickPendingIntent(R.id.btn_spoilers,pendingSpoilersClickIntent)
}
Log.i(TAG,"updateWidget: Calling updateWidget!") // This is logged
appWidgetManager.updateAppWidget(appWidgetId,remoteViews) // NO EFFECT FROM THIS CALL!!
}
}
解决方法
传递给 remoteViews 的布局似乎已被缓存,您必须使用不同的布局才能使其工作。我使用了两种不同的布局来根据布尔值更新小部件,并且效果很好。
val remoteViews = if (spoilers) RemoteViews(context.packageName,R.layout.appwidget_spoilers) else RemoteViews(context.packageName,R.layout.appwidget_no_spoilers)
布局可以相似,但必须有一些不同。就我而言,我为 ImageView 使用了不同的可绘制对象。
