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 " );
                                }
                            }
                        });
