零、前言：
[1]两行代码解决运行时权限
[2]用户拒绝后显示提示信息，有再次验证功能
[3]验证成功回调
一个权限效果：

一、代码实现
1.单一权限申请
public class MainActivity extends PermissionActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//单权限申请
applyPermissions(_WRITE_EXTERNAL_STORAGE());
}
@Override
protected void permissionOk() {
ToastUtil.showAtOnce(MainActivity.this, "授权通过");
}
}
2.多权限：常用的六组运行时权限
applyPermissions(
_WRITE_EXTERNAL_STORAGE(), _READ_CONTACTS(),
_CALL_PHONE(), _CAMERA(), _READ_SMS(), _RECORD_AUDIO());

附录二：危险权限：需要运行时
group:android.permission-group.CONTACTS 通讯录方面
permission:android.permission.WRITE_CONTACTS 写入通讯录
permission:android.permission.GET_ACCOUNTS 访问通讯录权限
permission:android.permission.READ_CONTACTS 读取通讯录
group:android.permission-group.PHONE 电话方面
permission:android.permission.READ_CALL_LOG 看电话记录
permission:android.permission.READ_PHONE_STATE 读取手机状态
permission:android.permission.CALL_PHONE 打电话
permission:android.permission.WRITE_CALL_LOG 编写调用日志
permission:android.permission.USE_SIP 使用SIP
permission:android.permission.PROCESS_OUTGOING_CALLS 过程输出调用 permission:com.android.voicemail.permission.ADD_VOICEMAIL 添加语音信箱
group:android.permission-group.CALENDAR 日历
permission:android.permission.READ_CALENDAR 读取日历
permission:android.permission.WRITE_CALENDAR 写入日历
group:android.permission-group.CAMERA 照相机
permission:android.permission.CAMERA
group:android.permission-group.SENSORS 传感器
permission:android.permission.BODY_SENSORS 体传感器
group:android.permission-group.LOCATION 位置
permission:android.permission.ACCESS_FINE_LOCATION 获取好位置
permission:android.permission.ACCESS_COARSE_LOCATION
获取粗定位group:android.permission-group.STORAGE 存储
permission:android.permission.READ_EXTERNAL_STORAGE 读取外部存储器
permission:android.permission.WRITE_EXTERNAL_STORAGE 写外部存储器
group:android.permission-group.MICROPHONE 扩音器；麦克风
permission:android.permission.RECORD_AUDIO 录音
group:android.permission-group.SMS 信息
permission:android.permission.READ_SMS 读取信息
permission:android.permission.RECEIVE_WAP_PUSH 收到WAP推送
permission:android.permission.RECEIVE_MMS 接收彩信
permission:android.permission.RECEIVE_SMS 收信息
permission:android.permission.SEND_SMS 发信息
运行时权限组中的一个获取权限，其他就不需要运行时权限，但AndroidManifest.xml仍要配置
