TI--安卓运行时权限封装

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：

六个权限演示：

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());

附录一：权限封装类，拷贝即用

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
