Android 动态获取权限类 PermissionUtils

1、导入第三方库：

api 'com.yanzhenjie:permission:2.0.3'

2、使用Java8

compileOptions {
   sourceCompatibility JavaVersion.VERSION_1_8
   targetCompatibility JavaVersion.VERSION_1_8
}

3、新建PermissUtils类：

import com.yanzhenjie.permission.AndPermission;

/**
 * Android权限申请工具类
 */
public class PermissionUtils {

    public static final String PERMISSION_RECORD_AUDIO = Manifest.permission.RECORD_AUDIO;
    public static final String PERMISSION_GET_ACCOUNTS = Manifest.permission.GET_ACCOUNTS;
    public static final String PERMISSION_READ_PHONE_STATE = Manifest.permission.READ_PHONE_STATE;
    public static final String PERMISSION_CALL_PHONE = Manifest.permission.CALL_PHONE;
    public static final String PERMISSION_CAMERA = Manifest.permission.CAMERA;
    public static final String PERMISSION_ACCESS_FINE_LOCATION = Manifest.permission.ACCESS_FINE_LOCATION;
    public static final String PERMISSION_ACCESS_COARSE_LOCATION = Manifest.permission.ACCESS_COARSE_LOCATION;
    public static final String PERMISSION_WRITE_SEIINGS = Manifest.permission.WRITE_SETTINGS;
    public static final String PERMISSION_READ_EXTERNAL_STORAGE = Manifest.permission.READ_EXTERNAL_STORAGE;
    public static final String PERMISSION_WRITE_EXTERNAL_STORAGE = Manifest.permission.WRITE_EXTERNAL_STORAGE;

    /**
     * 注释：权限申请回调
     */
    public interface PermissionListener {
        void onSuccess(Context context);
        void onFailed(Context context);
    }

    /**
     * 注释：应用相关组权限
     */
     public static void applicationPermissions(Context context, PermissionListener listener, String[]... permissions) {
        if (Build.VERSION.SDK_INT > Build.VERSION_CODES.M) {
            if (!AndPermission.hasPermissions(context, permissions)) {
                AndPermission.with(context)
                        .runtime()
                        .permission(permissions)
                        .onGranted((permission) -> {
                            listener.onSuccess(context);
                        })
                        .onDenied((permission) -> {
                            listener.onFailed(context);
                        })
                        .start();
            } else {
                listener.onSuccess(context);
            }
        } else {
            listener.onSuccess(context);
        }
    }

    /**
     * 注释：应用相关单个权限
     */
    @SuppressLint("WrongConstant")
    public static void applicationPermissions(Context context, PermissionListener listener, String... permissions) {
        if (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP_MR1) {
            if (!AndPermission.hasPermissions(context, permissions)) {
                AndPermission.with(context)
                        .runtime()
                        .permission(permissions)
                        .onGranted((permission) -> {
                            listener.onSuccess(context);
                        })
                        .onDenied((permission) -> {
                            listener.onFailed(context);
                        })
                        .start();
            } else {
                listener.onSuccess(context);
            }
        } else {
            listener.onSuccess(context);
        }
    }

}

4、使用方法：

 private void  requestCameraPermission(){
        PermissionUtils.applicationPermissions(this, new PermissionUtils.PermissionListener() {
            @Override
            public void onSuccess(Context context) {
                //已获取权限
            }

            @SuppressLint("ShowToast")
            @Override
            public void onFailed(Context context) {
                //未获取权限，需要获取权限
                if (AndPermission.hasAlwaysDeniedPermission(context, PermissionUtils.PERMISSION_CAMERA)
                        && AndPermission.hasAlwaysDeniedPermission(context, PermissionUtils.PERMISSION_READ_EXTERNAL_STORAGE)
                            && AndPermission.hasAlwaysDeniedPermission(context, PermissionUtils.PERMISSION_WRITE_EXTERNAL_STORAGE)) {
                    AndPermission.with(context).runtime().setting().start(PERMISSION_MEDIA_REQUEST_CODE);
                }else {
                    Toast.makeText(context, "拒绝授权,请授权使用",Toast.LENGTH_SHORT);
                }
                finish();
            }
        },PermissionUtils.PERMISSION_CAMERA,PermissionUtils.PERMISSION_READ_EXTERNAL_STORAGE,PermissionUtils.PERMISSION_WRITE_EXTERNAL_STORAGE);
    }
