RemoteViews AppWidget AdapterViewFlipper我有一个AppWidget，当用户点击RemoteViews中的按钮时，该AppWdiget会被翻转。根据官方文档，这应该通过致电showNext()上的showNext来完成。然后应使用partiallyUpdateAppWidget更新public class WidgetProvider extends AppWidgetProvider {
public static final String NEXT = "next";
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
for (int appWidgetId : appWidgetIds) {
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
Intent nextIntent = new Intent(context, WidgetProvider.class);
nextIntent.setAction(NEXT);
views.setOnClickPendingIntent(R.id.next_button,
PendingIntent.getBroadcast(context, appWidgetId, nextIntent,
PendingIntent.FLAG_UPDATE_CURRENT));
views.setRemoteAdapter(R.id.view_flipper, new Intent(context,
WidgetRemoteViewService.class));
appWidgetManager.updateAppWidget(appWidgetId, views);
}
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
@Override
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equals(NEXT)) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(),
R.layout.widget_layout);
remoteViews.showNext(R.id.view_flipper);
AppWidgetManager.getInstance(context).partiallyUpdateAppWidget(
AppWidgetManager.getInstance(context).getAppWidgetIds(
new ComponentName(context, WidgetProvider.class)),
remoteViews);
}
super.onReceive(context, intent);
}
}
，其中partiallyUpdateAppWidget函数作为示例在文档中。我已经尝试过实施这一点，而且我很可能犯了一些我无法理解的愚蠢错误。
updateAppWidget当用RemoteViews替换import pymysql
import json
conn = pymysql.connect(host='localhost', port=3306, user='root', passwd='',
db='mydb', charset='utf8mb4', cursorclass=pymysql.cursors.DictCursor)
cursor = conn.cursor()
select_query = "select * from users where id = "
ids = ["10", "20", "34", "1"]
for x in ids:
var = select_query + str(x) # here
# print(var)
print(list(cursor.execute(var)))
时，下一个按钮正在工作，直到方向改变或手机进入睡眠状态，这会强制重绘最后存储的confirm("message");//for confirm you should have to click ok to do other things
alert("message");//it will alert whatever inside .
。这让我相信我所犯的错误与部分更新有关，但我无法弄清楚我做错了什么。

您在测试哪个API级别？
