Android 动态权限申请的封装

此模块基于AndPermission进行二次封装

为AndPermission加入依赖

implementation 'com.yanzhenjie:permission:2.0.3' //添加依赖

封装类CheckPermission

public class CheckPermission {

    private  Context context;
    private static CheckPermission checkPermission;
    private static final String PACKAGE_HEADER = "package:";


    public  CheckPermission(Context context) {
        this.context = context;
    }

    /**
     * 获取权限
     *
     * @param listener
     * @param permission
     */
    @SuppressLint("WrongConstant")
    public void requestPermission(String [] permission,final PermissionLinstener listener) {
        AndPermission.with(context)
                    .runtime()
                    .permission(permission)
//                    .rationale(context)//添加拒绝权限回调
                    .onGranted(new Action<List<String>>() {
                        @Override
                        public void onAction(List<String> data) {
                            // data.get(0);
                            Log.d("permission", data.get(0));
                            listener.onSuccess(context,data);
                        }
                    })
                    .onDenied(new Action<List<String>>() {
                        @Override
                        public void onAction(List<String> data) {
                            /**
                             * 当用户没有允许该权限时，回调该方法
                             */
                            listener.onFailed(context,data);
                            /**
                             * 判断用户是否点击了禁止后不再询问，AndPermission.hasAlwaysDeniedPermission(MainActivity.this, data)
                             * 如要引导用户跳转至应该权限设置页面，可用intent
                             */
                            if (AndPermission.hasAlwaysDeniedPermission(context, data)) {
                                //true，弹窗再次向用户索取权限
                                listener.onNotApply(context,data);
                            }
                        }
                    }).start();
    }

    /**
     * 引导用户到系统设置页面
     */
    public void GuidePermission(){
        Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
        intent.setData(Uri.parse(PACKAGE_HEADER + context.getPackageName()));
        context.startActivity(intent);

    }

    public interface PermissionLinstener {
        void onSuccess(Context context,List<String> data);
        void onFailed(Context context,List<String> data);
        void onNotApply(Context context,List<String> data);
    }

}

使用案例

final String [] strings = new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_EXTERNAL_STORAGE};

new CheckPermission(context).requestPermission(strings, new CheckPermission.PermissionLinstener() {
                    @Override
                    public void onSuccess(Context context, List<String> data) {
                        Toast.makeText(context, "申请成功", Toast.LENGTH_SHORT).show();

                    }

                    @Override
                    public void onFailed(Context context, List<String> data) {
                        Toast.makeText(context, "申请失败", Toast.LENGTH_SHORT).show();

                    }
              		/**
                 	 *  可在此调用，GuidePermission();引导用户前往系统设置页面获取权限
                     * @param context
                     * @param data
                     */
                    @Override
                    public void onNotApply(final Context context, List<String> data) {
                                            Toast.makeText(context, "用户点击了不再提示", Toast.LENGTH_SHORT).show();

                    }
                });

不要忘了在清单中，加入注册权限

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