android widget无法点击问题

RemoteViews views = new RemoteViews(mContext.getPackageName(), R.layout.widget);

view.setXXXX();

PendingIntent pendingIntent = PendingIntent.getActivity(mContext, 0, intent, 0);
views.setOnClickPendingIntent(R.id.widget, pendingIntent);

AppWidgetManager awg = AppWidgetManager.getInstance(mContext);
awg.updateAppWidget(new ComponentName(mContext, QQPlayWidgetProvider.class), views);

这个为widget设置了点击事件处理，但是后来只想更新部分UI，不想改变点击事件处理，于是采用了下面的更新方式：

RemoteViews views = new RemoteViews(mContext.getPackageName(), R.layout.widget);

view.setXXXX();

AppWidgetManager awg = AppWidgetManager.getInstance(mContext);
awg.updateAppWidget(new ComponentName(mContext, QQPlayWidgetProvider.class), views);

这样的话会将之前的：

PendingIntent pendingIntent = PendingIntent.getActivity(mContext, 0, intent, 0);
views.setOnClickPendingIntent(R.id.widget, pendingIntent);

这个操作冲掉，导致无法点击，所以每次更新时需要将对views的所有设置都写一遍，

RemoteViews views = new RemoteViews(mContext.getPackageName(), R.layout.widget);

view.setXXXX();

PendingIntent pendingIntent = PendingIntent.getActivity(mContext, 0, intent, 0);
views.setOnClickPendingIntent(R.id.widget, pendingIntent);

AppWidgetManager awg = AppWidgetManager.getInstance(mContext);
awg.updateAppWidget(new ComponentName(mContext, QQPlayWidgetProvider.class), views);

保证每次更新都能将所有的操作更新
