一、RxPermission使用

1、引用依赖：

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

dependencies {
    implementation 'com.github.tbruyelle:rxpermissions:0.10.2'
}

2、AndroidManifest.xml声明权限

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_CALENDAR" />

3、使用用例

①.申请单个权限

    public void checkPermissionRequest(FragmentActivity activity) {
        RxPermissions permissions = new RxPermissions(activity);
        permissions.setLogging(true);
        permissions.request(Manifest.permission.READ_EXTERNAL_STORAGE)
                .subscribe(new Consumer<Boolean>() {
                    @Override
                    public void accept(Boolean aBoolean) throws Exception {
                        LogUtils.error(TAG, "checkPermission22--:" + aBoolean);
                    }
                });
    }

总结

1、返回true：申请成功 ；返回false：申请失败
2、同意后，之后再申请此权限则不再弹出提示框
3、不要使用compose方法，如RxLifeCycle

②.申请多个权限

    public void checkPermissionRequest(FragmentActivity activity) {
        RxPermissions permissions = new RxPermissions(activity);
        permissions.setLogging(true);
        permissions.request(Manifest.permission.READ_EXTERNAL_STORAGE,
                Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_CALENDAR)
                .subscribe(new Consumer<Boolean>() {
                    @Override
                    public void accept(Boolean aBoolean) throws Exception {
                        LogUtils.error(TAG, "checkPermission22--:" + aBoolean);
                    }
                });
    }

总结

1、只要有一个禁止，则返回false；全部同意，则返回true。
2、某个权限同意后，之后再申请此权限则不再弹出提示框，其他的会继续弹出
3、此申请三个权限，但只会有两个弹窗，READ_EXTERNAL_STORAGE和WRITE_EXTERNAL_STORAGE 是属于一组，

③.申请单个权限，获得详细信息

    public void checkPermissionRequestEach(FragmentActivity activity) {
        RxPermissions permissions = new RxPermissions(activity);
        permissions.setLogging(true);
        permissions.requestEach(Manifest.permission.READ_EXTERNAL_STORAGE)
                .subscribe(new Consumer<Permission>() {
                    @Override
                    public void accept(Permission permission) throws Exception {
                        LogUtils.error(TAG, "checkPermissionRequestEach--:" + "-permission-:" + permission.name + "---------------");
                        if (permission.name.equalsIgnoreCase(Manifest.permission.READ_EXTERNAL_STORAGE)) {
                            if (permission.granted) {//同意后调用
                                LogUtils.error(TAG, "checkPermissionRequestEach--:" + "-READ_EXTERNAL_STORAGE-:" + true);
                            } else if (permission.shouldShowRequestPermissionRationale){//禁止，但没有选择“以后不再询问”，以后申请权限，会继续弹出提示
                                LogUtils.error(TAG, "checkPermissionRequestEach--:" + "-READ_EXTERNAL_STORAGE-shouldShowRequestPermissionRationale:" + false);
                            }else {//禁止，但选择“以后不再询问”，以后申请权限，不会继续弹出提示
                                LogUtils.error(TAG, "checkPermissionRequestEach--:" + "-READ_EXTERNAL_STORAGE-:" + false);
                            }
                        }
                    }
                });
    }

总结

1、只返回一个Permission对象

④.申请多个权限，获得详细信息

 public void checkPermissionRequestEach(FragmentActivity activity) {
        RxPermissions permissions = new RxPermissions(activity);
        permissions.setLogging(true);
        permissions.requestEach(Manifest.permission.READ_EXTERNAL_STORAGE,
                Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_CALENDAR)
                .subscribe(new Consumer<Permission>() {
                    @Override
                    public void accept(Permission permission) throws Exception {
                        LogUtils.error(TAG, "checkPermissionRequestEach--:" + "-permission-:" + permission.name + "---------------");
                        if (permission.name.equalsIgnoreCase(Manifest.permission.READ_EXTERNAL_STORAGE)) {
                            if (permission.granted) {//同意后调用
                                LogUtils.error(TAG, "checkPermissionRequestEach--:" + "-READ_EXTERNAL_STORAGE-:" + true);
                            } else if (permission.shouldShowRequestPermissionRationale){//禁止，但没有选择“以后不再询问”，以后申请权限，会继续弹出提示
                                LogUtils.error(TAG, "checkPermissionRequestEach--:" + "-READ_EXTERNAL_STORAGE-shouldShowRequestPermissionRationale:" + false);
                            }else {//禁止，但选择“以后不再询问”，以后申请权限，不会继续弹出提示
                                LogUtils.error(TAG, "checkPermissionRequestEach--:" + "-READ_EXTERNAL_STORAGE-:" + false);
                            }
                        }
                        if (permission.name.equalsIgnoreCase(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
                            if (permission.granted) {
                                LogUtils.error(TAG, "checkPermissionRequestEach--:" + "-WRITE_EXTERNAL_STORAGE-:" + true);
                            }else if (permission.shouldShowRequestPermissionRationale){
                                LogUtils.error(TAG, "checkPermissionRequestEach--:" + "-READ_EXTERNAL_STORAGE-shouldShowRequestPermissionRationale:" + false);
                            } else {
                                LogUtils.error(TAG, "checkPermissionRequestEach--:" + "-WRITE_EXTERNAL_STORAGE-:" + false);
                            }
                        }
                        if (permission.name.equalsIgnoreCase(Manifest.permission.READ_CALENDAR)) {
                            if (permission.granted) {
                                LogUtils.error(TAG, "checkPermissionRequestEach--:" + "-READ_CALENDAR-:" + true);
                            }else if (permission.shouldShowRequestPermissionRationale){
                                LogUtils.error(TAG, "checkPermissionRequestEach--:" + "-READ_EXTERNAL_STORAGE-shouldShowRequestPermissionRationale:" + false);
                            } else {
                                LogUtils.error(TAG, "checkPermissionRequestEach--:" + "-READ_CALENDAR-:" + false);
                            }
                        }
                    }
                });
    }

总结

1、返回三个permission对象

⑤.申请多个权限，获取合并后的详细信息

   public void checkPermissionRequestEachCombined(FragmentActivity activity) {
        RxPermissions permissions = new RxPermissions(activity);
        permissions.setLogging(true);
        permissions.requestEachCombined(Manifest.permission.READ_EXTERNAL_STORAGE,
                Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_CALENDAR)
                .subscribe(new Consumer<Permission>() {
                    @Override
                    public void accept(Permission permission) throws Exception {
                        LogUtils.error(TAG, "checkPermissionRequestEachCombined--:" + "-permission-:" + permission.name + "---------------");
                        if (permission.granted) {//全部同意后调用
                            LogUtils.error(TAG, "checkPermissionRequestEachCombined--:" + "-READ_EXTERNAL_STORAGE-:" + true);
                        } else if (permission.shouldShowRequestPermissionRationale) {//只要有一个选择：禁止，但没有选择“以后不再询问”，以后申请权限，会继续弹出提示
                            LogUtils.error(TAG, "checkPermissionRequestEachCombined--:" + "-READ_EXTERNAL_STORAGE-shouldShowRequestPermissionRationale:" + false);
                        } else {//只要有一个选择：禁止，但选择“以后不再询问”，以后申请权限，不会继续弹出提示
                            LogUtils.error(TAG, "checkPermissionRequestEachCombined--:" + "-READ_EXTERNAL_STORAGE-:" + false);
                        }
                    }
                });
    }

4、使用用例结合RxJava

 public void checkPermissionsEnsure(FragmentActivity activity) {
        final RxPermissions permissions = new RxPermissions(activity);
        permissions.setLogging(true);
        Observable.timer(100, TimeUnit.MILLISECONDS)
                .compose(permissions.ensure(Manifest.permission.READ_EXTERNAL_STORAGE))
                .subscribe(new Consumer<Boolean>() {
                    @Override
                    public void accept(Boolean aBoolean) throws Exception {
                        LogUtils.error(TAG, "checkPermissionsEnsure--:" + "-READ_EXTERNAL_STORAGE-:" + aBoolean);
                    }
                });
    }

总结

1、ensure、ensureEach、ensureEachCombined用法跟之前类似

5、判断某个权限是否被申请

    /**
     * 检查某个权限是否被申请
     *
     * @param activity
     */
    public void checkPermissionsIsGranted(FragmentActivity activity) {
        RxPermissions permissions = new RxPermissions(activity);
        permissions.setLogging(true);
        LogUtils.error(TAG, "checkPermissionsIsGranted--:" + "-WRITE_EXTERNAL_STORAGE-:" + permissions.isGranted(Manifest.permission.WRITE_EXTERNAL_STORAGE));
    }
