在函数 onRequestPermissionsResult 中的对话框生成器中按下是按钮后，我的代码陷入无限循环

Question

在 onRequestPermissionsResult 函数的对话框生成器中按下是按钮后，我的代码陷入无限循环。当我按下 yes.Also 后，生成器一次又一次地出现，我的应用程序退出但当我再次打开它时它显示对话框构建器

@Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull final int[] grantResults) {

        switch (requestCode) {
            case 0: {
                boolean anyPermissionDenied = false;
                boolean neverAskAgainSelected = false;
                for (int i = 0; i < grantResults.length; i++) {
                    if (grantResults[i] != PackageManager.PERMISSION_GRANTED) {
                        anyPermissionDenied = true;
                    }
                }
                if (!anyPermissionDenied)
                {
                    getConfigFromServer();
                } else {
                    String message = "";
                    if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_FINE_LOCATION) ||
                            ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)
                            || ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.WRITE_EXTERNAL_STORAGE))  {

                        requestPermission();
                    }
                    else
                    {
                        message = "You have to give all permission to continue";
                    }
                    AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
                    alertDialogBuilder.setMessage(message);
                            alertDialogBuilder.setPositiveButton("yes",
                                    new DialogInterface.OnClickListener() {
                                        @Override
                                        public void onClick(DialogInterface arg0, int arg1) {
                                        requestPermission();

                                        }
                                    });

                    alertDialogBuilder.setNegativeButton("No",new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            finish();
                        }
                    });

                    AlertDialog alertDialog = alertDialogBuilder.create();
                    alertDialog.show();
                }
            }
            break;
            default:
                super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }


    }

请求权限代码

    void requestPermission() {
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED
                || ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED
                || ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.CAMERA,
                    Manifest.permission.ACCESS_FINE_LOCATION}, 0);
        } else {

            getConfigFromServer();
            //navigateToNextActivity();
        }
    }

Answer 1

它在单击否后再次弹出，因为你没有在 onRequestPermissionsResult 中设置任何东西，你的 if-condition anyPermissionDenied 发生了，但是对于 alertDialogBuilder.setPositiveButton("yes",new DialogInterface.OnClickListener() 我认为如果你 post 你的 requestPermission mehtod 或者至少你应该调试它看看发生了什么

我测试了你的代码及其循环，所以已经编辑了你的代码，它会对你有所帮助。
