如何一次请求多个权限？

Question

我有一个应用程序，该应用程序请求4个重要权限：阅读联系人，发送短信，录音，精确定位。使用我的代码，每次我的应用程序启动时，它都会请求四个权限之一，这意味着您必须打开该应用程序四次才能获得所有权限。

            if (ContextCompat.checkSelfPermission(this,
                Manifest.permission.READ_CONTACTS)
                != PackageManager.PERMISSION_GRANTED) {
            // No explanation needed; request the permission
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.READ_CONTACTS},
                    MY_PERMISSIONS_REQUEST_READ_CONTACTS);
        }

        if (ContextCompat.checkSelfPermission(this,
                Manifest.permission.RECORD_AUDIO)
                != PackageManager.PERMISSION_GRANTED) {
            // No explanation needed; request the permission
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.RECORD_AUDIO},
                    MY_PERMISSIONS_REQUEST_RECORD_AUDIO);
        }

        if (ContextCompat.checkSelfPermission(this,
                Manifest.permission.SEND_SMS)
                != PackageManager.PERMISSION_GRANTED) {
            // No explanation needed; request the permission
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.SEND_SMS},
                    MY_PERMISSIONS_REQUEST_SEND_SMS);
        }

        if (ContextCompat.checkSelfPermission(this,
                Manifest.permission.ACCESS_FINE_LOCATION)
                != PackageManager.PERMISSION_GRANTED) {
            // No explanation needed; request the permission
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                    MY_PERMISSIONS_REQUEST_FINE_LOCATION);
        }

当然，必须有一种方法可以将这些项目变成一堆权限。我该怎么做？
