User's don't really have the option to chose which permissions they approve or not. It's either they approve everything and your app installs, or they chose to decline and then your app doesn't install.

用户实际上没有选择他们批准或不批准的权限。要么他们批准了所有内容并且您的应用安装了，要么他们选择拒绝，然后您的应用无法安装。

However, to answer your question you can use the checkPermission method in the PackageManager

但是，要回答您的问题，您可以使用PackageManager中的checkPermission方法

PackageManager manager = getPackageManager();
int hasPermission = manager.checkPermission ("android.permission.READ_CONTACTS", "com.your.package")
if (hasPermission == manager.PERMISSION_GRANTED) {
    //you have permission
}
