步骤：

1、初始化

dependencies {    implementation 'io.reactivex.rxjava2:rxandroid:2.0.1'    implementation 'io.reactivex.rxjava2:rxjava:2.1.0'    implementation 'com.github.tbruyelle:rxpermissions:0.10.2'}

2、用法

检测是否有某权限

        RxPermissions permissions = new RxPermissions(this);        permissions.setLogging(true);        Log.d(TAG, "checkPermissionsIsGranted WRITE_EXTERNAL_STORAGE " + permissions.isGranted(Manifest.permission.WRITE_EXTERNAL_STORAGE));

申请单个权限

                RxPermissions permissions = new RxPermissions(RxPermissionsActivity.this);                permissions.setLogging(true);                permissions.request(Manifest.permission.CAMERA)                        .subscribe(new Consumer<Boolean>() {                            @Override                            public void accept(Boolean aBoolean) throws Exception {                                Log.d(TAG, "text_camera aBoolean " + aBoolean);                            }                        });

申请多个权限

                RxPermissions rxPermissions = new RxPermissions(RxPermissionsActivity.this);                rxPermissions.requestEach(Manifest.permission.READ_SMS)                        .subscribe(new Consumer<Permission>() {                            @Override                            public void accept(Permission permission) throws Exception {                                if (permission.granted) {                                    // 用户已经同意该权限                                    Log.d(TAG, "text_sms granted" );                                    //result.agree(permission);                                } else if (permission.shouldShowRequestPermissionRationale) {                                    // 用户拒绝了该权限，没有选中『不再询问』（Never ask again）,那么下次再次启动时，还会提示请求权限的对话框                                    //result.refuse(permission);                                    Log.d(TAG, "text_sms shouldShowRequestPermissionRationale" );                                } else {                                    // 用户拒绝了该权限，并且选中『不再询问』，提醒用户手动打开权限                                    //result.noMoreQuestions(permission);                                    Log.d(TAG, "text_sms " );                                }                            }                        });
