Android-动态申请权限-及打开权限设置

一:

package com.vitamio.dome;

/**
 * 权限申请接口 再 Activity 中实现该接口
 * 在 要申请权限的Activity 中实现此接口
 */
public interface PermissionInterface {
    /**
     * 可设置请求权限请求码
     * 设置权限请求requestCode，只要不跟onRequestPermissionsResult方法中的其他请求码冲突即可。
     * 可以自己创建一个 请求码的管理类,将项目中所有的请求码写在这个类中,做统一管理
     */
    int getPermissionsRequestCode();

    /**
     * 设置需要请求的权限
     */
    String[] getPermissions();

    /**
     * 请求权限成功回调
     */
    void requestPermissionsSuccess();

    /**
     * 请求权限失败回调
     */
    void requestPermissionsFail();

}

二:权限工具类,提取公共方法

package com.vitamio.dome;

import android.app.Activity;
import android.content.Context;
import android.content.pm.PackageManager;
import android.os.Build;

import java.util.ArrayList;

/**
 * 动态权限工具类
 */
public class PermissionUtil {
    /**
     * Main的权限请求返回码
     */
    public static int mainPermissionCode = 1000;
    /**
     * 判断是否有某个权限
     * @param context
     * @param permission
     * @return
     */
    public static boolean hasPermission(Context context, String permission){
        //Build.VERSION.SDK_INT :获取当前手机的 android 版本
        //6.0以上才进行检测
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            if(context.checkSelfPermission(permission)  != PackageManager.PERMISSION_GRANTED){
                return false;
            }
        }
        return true;
    }

    /**
     * 弹出对话框请求权限
     * @param activity
     * @param permissions
     * @param requestCode
     */
    public static void requestPermissions(Activity activity, String[] permissions, int requestCode){
        //Build.VERSION.SDK_INT :获取当前手机的 android 版本
        //6.0以上才进行请求
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            activity.requestPermissions(permissions, requestCode);
        }
    }

    /**
     * 返回缺失的权限
     * @param context
     * @param permissions
     * @return 返回缺少的权限，null 意味着没有缺少权限
     */
    public static String[] getDeniedPermissions(Context context, String[] permissions){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            ArrayList deniedPermissionList = new ArrayList<>();
            for(String permission : permissions){
                if(context.checkSelfPermission(permission) != PackageManager.PERMISSION_GRANTED){
                    deniedPermissionList.add(permission);
                }
            }
            int size = deniedPermissionList.size();
            if(size > 0){
                return deniedPermissionList.toArray(new String[deniedPermissionList.size()]);
            }
        }
        return null;
    }
}

三:权限被拒绝后打开权限设置工具类

package com.vitamio.dome;

import android.content.ActivityNotFoundException;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import android.net.Uri;
import android.os.Build;
import android.provider.Settings;
import android.util.Log;
import android.widget.Toast;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.List;

/**
 * 打开权限设置界面
 */
public class PermissionPageUtils {
    private final String TAG = "PermissionPageManager";
    private Context mContext;
    //自己的项目包名
    private String packageName="com.vitamio.dome";

    public PermissionPageUtils(Context context) {
        this.mContext = context;
    }

    /**
     * 进入权限设置界面
     */
    public void OpenPermissionPage() {
        String name = Build.MANUFACTURER;
        Log.e(TAG, "jumpPermissionPage --- name : " + name);
        switch (name) {
            case "HUAWEI":
                goHuaWeiMainager();
                break;
            case "vivo":

            default:

四:动态权限帮助类,在Activity中调用该类进行动态权限申请

package com.vitamio.dome;

import android.app.Activity;
import android.content.pm.PackageManager;
import android.support.annotation.NonNull;

/**
 * 动态权限帮助类,在Activity中调用该类进行动态权限申请
 */
public class PermissionHelper {
    private Activity mActivity;
    private PermissionInterface mPermissionInterface;

    public PermissionHelper(@NonNull Activity activity, @NonNull PermissionInterface permissionInterface) {
        mActivity = activity;
        mPermissionInterface = permissionInterface;
    }

    /**
     * 开始请求权限。
     * 方法内部已经对Android M 或以上版本进行了判断，外部使用不再需要重复判断。
     * 如果设备还不是M或以上版本，则也会回调到requestPermissionsSuccess方法。
     */
    public void requestPermissions(){
        String[] deniedPermissions = PermissionUtil.getDeniedPermissions(mActivity, mPermissionInterface.getPermissions());
        if(deniedPermissions != null && deniedPermissions.length > 0){
            //弹出申请全新框
            PermissionUtil.requestPermissions(mActivity, deniedPermissions, mPermissionInterface.getPermissionsRequestCode());
        }else{
            mPermissionInterface.requestPermissionsSuccess();
        }
    }

    /**
     * 在Activity中的onRequestPermissionsResult中调用
     * @param requestCode
     * @param permissions
     * @param grantResults
     * @return true 代表对该requestCode感兴趣，并已经处理掉了。false 对该requestCode不感兴趣，不处理。
     */

        if(requestCode == mPermissionInterface.getPermissionsRequestCode()){
            boolean isAllGranted = true;//是否全部权限已授权
            for(int result : grantResults){
                if(result == PackageManager.PERMISSION_DENIED){
                    isAllGranted = false;
                    break;

五:调用,开始动态申请权限

package com.vitamio.dome;

    //直播 rtmp 流视频
    private VideoView vitamio_videoview;
    private String path;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        permissionPageUtils = new PermissionPageUtils(this.getApplicationContext());
        setContentView(R.layout.activity_main);
        permissionHelper.requestPermissions();

    }

    //onRequestPermissionsResult

   //权限申请回调
    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        permissionHelper.requestPermissionsResult(requestCode, permissions, grantResults);
    }

    /**
     * 设置播放视频
     */
    private void settingVoide() {

        path = "rtmp://202.69.69.180:443/webcast/bshdlive-pc";
        //放入地址
        vitamio_videoview.setVideoPath(path);

        //设置控制栏

    }
    
    //设置申请权限请求返回码
    @Override

    }

    //设置要申请的权限 
    @Override
    public String[] getPermissions() {
        return new String[]{
                //读取设备外部存储空间权限
                Manifest.permission.READ_EXTERNAL_STORAGE
        };

    }

    //获取权限成功执行的方法
    @Override
    public void requestPermissionsSuccess() {
        settingVoide();
    }

    //获取权限失败执行的方法
    @Override
    public void requestPermissionsFail() {
        //android.permission.READ_EXTERNAL_STORAGE
        String[] permissionAry = new String[]{Manifest.permission.READ_EXTERNAL_STORAGE};
        //获取被拒绝的权限
        String[] juPermission = PermissionUtil.getDeniedPermissions(this, permissionAry);
        //打开权限设置
        permissionPageUtils.OpenPermissionPage();

    }
}
