Android6.0动态加载权限

Android 6.0加入了动态权限，权限有普通权限和危险权限两种，其中危险权限在6.0以上的手机是需要动态添加权限的，举例：拨打10086

//-----------------布局文件---------------

<Button
    android:layout_width="match_parent"
 android:layout_height="wrap_content"  android:text="拨打10086"  android:onClick="button"/> //-----------清单文件中添加权限---------------------------- 

<uses-permission android:name="android.permission.CALL_PHONE" />


//-----------------Activity中----------------------------------------
