我已經閱讀了大約10篇關於onclick事件和Widgets的文章,並且我明白它們的實現方式有所不同。然而,儘管其他人的成功,我似乎發現它不可能得到它的工作。我正在使用Android Studio 2.2並創建了一個簡單的測試應用程序。我有一個叫做按鈕的按鈕。當我按下按鈕時,我想要吐司顯示。Android Widget的Onclick事件
我已經複製了其他帖子中建議的代碼。有人可以看一看,看看我是否做錯了什麼?
public class NewAppWidget extends AppWidgetProvider {
private static final String MyOnClick = "myOnClickTag";
protected PendingIntent getPendingSelfIntent(Context context, String action) {
Intent intent = new Intent(context, getClass());
intent.setAction(action);
return PendingIntent.getBroadcast(context, 0, intent, 0);
}
void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
int appWidgetId) {
CharSequence widgetText = context.getString(R.string.appwidget_text);
// Construct the RemoteViews object
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.new_app_widget);
views.setOnClickPendingIntent(R.id.button, getPendingSelfIntent(context, MyOnClick));
views.setTextViewText(R.id.appwidget_text, widgetText);
// Instruct the widget manager to update the widget
appWidgetManager.updateAppWidget(appWidgetId, views);
}
//RemoteViews.setOnClickPendingIntent(R.id.button, getPendingSelfIntent(context, MyOnClick));
@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);
}
}
@Override
public void onEnabled(Context context) {
// Enter relevant functionality for when the first widget is created
}
@Override
public void onDisabled(Context context) {
// Enter relevant functionality for when the last widget is disabled
}
@Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);//add this line
if (MyOnClick.equals(intent.getAction())){
//your onClick action is here
//display in short period of time
Toast.makeText(context, "msg msgasdasd", Toast.LENGTH_SHORT).show();
}
};
}
