【JAVA UI】HarmonyOs 怎么集成XxPermissions

 资料参考

参考资料XXPermissions和权限开发指导

项目集成

1、项目级的build.gradle，添加如下代码

allprojects {
    repositories {
        repositories{
            mavenCentral()
        }
    }
}

2、应用级的build.gradle添加如下代码

implementation 'io.openharmony.tpc.thirdlib:XXPermissions:1.0.3'

api讲解

1、检查权限 使用XXPermissions.hasPermission的方法

      /**
         * 第一个参数当前context
         * 第二个参数是申请权限名称
         * return  boolean参数
         * 返回是否存在该权限
         *若为true 表示存在该权限 若为false表示不存在该权限
         */
        boolean isexists = XXPermissions.hasPermission(MainAbilitySlice.this, Permission.CAMERA);

2、申请权限 代码如下

  XXPermissions.with(MainAbilitySlice.this)
                .permission(Permission.CAMERA)//todo 申请权限名称
                .request(new OnPermission() {
                    @Override
                    public void hasPermission(List<String> granted, boolean all) {//todo  权限允许的回调
                        if (all) {
                            mTextResult.setText("获取拍照权限成功");
                        }
                    }

                    @Override
                    public void noPermission(List<String> denied, boolean never) {//todo 权限背景
                        if (never) {
                            mTextResult.setText("被永久拒绝授权，请手动授予拍照权限");
                            //todo  如果是被永久拒绝就跳转到应用权限系统设置页面
                          
                        } else {
                            mTextResult.setText("获取拍照权限失败");
                        }
                    }
                });

3、跳转系统级应用

  String[] permissions = new String[denied.size()];
  denied.toArray(permissions);
  XPermissions.startPermissionActivity(MainAbilitySlice.this, permissions, this);

4、重写onAbilityResult代码如下

@Override
    protected void onAbilityResult(int requestCode, int resultCode, Intent resultData) {
        super.onAbilityResult(requestCode, resultCode, resultData);
        XXPermissions.onAbilityResult(requestCode);
        //todo 判断权限是否存在 若存在则不需要申请权限 若不存在 则重新申请权限
        mTextResult.setText("判断权限是否存在 若存在则不需要申请权限 若不存在 则重新申请权限");
    }

代码实现

在config.json添加拍照权限申请的代码，代码和效果图如下

  "reqPermissions": [
      {
        "name": "ohos.permission.CAMERA",
      }
    ],

在xml写一个申请权限的Text和显示结果的Text，代码如下

<?xml version="1.0" encoding="utf-8"?>
<DirectionalLayout
    xmlns:ohos="http://schemas.huawei.com/res/ohos"
    ohos:height="match_parent"
    ohos:width="match_parent"
    ohos:alignment="horizontal_center"
    ohos:orientation="vertical">
    <Text
        ohos:id="$+id:text_helloworld"
        ohos:height="100vp"
        ohos:width="match_parent"
        ohos:text_alignment="center"
        ohos:background_element="#ed6262"
        ohos:layout_alignment="center"
        ohos:text="申请权限"
        ohos:text_size="40vp"
        />

    <Text
        ohos:id="$+id:text_result"
        ohos:height="match_parent"
        ohos:width="match_parent"
        ohos:text_alignment="center"
        ohos:layout_alignment="center"
        ohos:text="权限结果"
        ohos:text_size="40vp"
        />


</DirectionalLayout>

java代码如下

package com.harmony.alliance.myapplication.slice;

import com.harmony.alliance.myapplication.MainAbility;
import com.harmony.alliance.myapplication.ResourceTable;
import com.hjq.permissions.OnPermission;
import com.hjq.permissions.Permission;
import com.hjq.permissions.XXPermissions;
import ohos.aafwk.ability.AbilitySlice;
import ohos.aafwk.content.Intent;
import ohos.agp.components.Component;
import ohos.agp.components.Text;

import java.util.List;

public class MainAbilitySlice extends AbilitySlice {
    Text mTextResult;

    @Override
    public void onStart(Intent intent) {
        super.onStart(intent);
        super.setUIContent(ResourceTable.Layout_ability_main);
        mTextResult = findComponentById(ResourceTable.Id_text_result);
        findComponentById(ResourceTable.Id_text_helloworld).setClickedListener(new Component.ClickedListener() {
            @Override
            public void onClick(Component component) {
                RequestPermissions();
            }
        });

    }

    public void RequestPermissions() {
        XXPermissions.with(MainAbilitySlice.this)
                .permission(Permission.CAMERA)//todo 申请权限名称
                .request(new OnPermission() {
                    @Override
                    public void hasPermission(List<String> granted, boolean all) {//todo  权限允许的回调
                        if (all) {
                            mTextResult.setText("获取拍照权限成功");
                        }
                    }

                    @Override
                    public void noPermission(List<String> denied, boolean never) {//todo 权限背景
                        if (never) {
                            mTextResult.setText("被永久拒绝授权，请手动授予拍照权限");
                            //todo  如果是被永久拒绝就跳转到应用权限系统设置页面
                            mTextResult.setText(" 如果是被永久拒绝就跳转到应用权限系统设置页面");
//                            String[] permissions = new String[denied.size()];
//                            denied.toArray(permissions);
//                            XXPermissions.startPermissionActivity(MainAbilitySlice.this, permissions, this);
                        } else {
                            mTextResult.setText("获取拍照权限失败");
                        }
                    }
                });

    }


}

运行效果
