获取安卓的默认日历问题

Question

做了一个日历应用，想要让我的应用到默认日历中，然后在网上搜索，但是无法实现，能不能用intent开放一个默认日历？请大家帮忙，谢谢。

Answer 1

应该是这么实现就可以：

PackageManager packmngr = this.getPackageManager(); 
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_LAUNCHER); 
List<ResolveInfo> list = packmngr.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED);
ResolveInfo Resolvebest = null;
for (final ResolveInfo info : list){
if (info.activityInfo.packageName.endsWith(".calendar"))
        Resolvebest = info;
}
if (Resolvebest != null){
 intent.setClassName(Resolvebest.activityInfo.packageName,
 Resolvebest.activityInfo.name);
 startActivity(intent);
}
