我的应用程序在应该请求许可时没有响应

Question

我正在编写一个 instagram 克隆代码，我必须请求外部存储许可，但是当我单击 imageView 时我的应用程序没有响应，我设置了 onClick 方法 (fotoSec) 以从图库中获取图像。

   fun fotoSec (view: View) {

    // Önce izin istenecek. İzin verilirse galeriye gidecek verilmezse uyarı mesajı gösterecek.
    // İzini bir kere verdiyse tekrar istenmeyecek direkt galeriye gidecek.
    if (ContextCompat.checkSelfPermission(this,android.Manifest.permission.READ_EXTERNAL_STORAGE)!=PackageManager.PERMISSION_GRANTED) {
        //İzin verilmemiş.
        ActivityCompat.requestPermissions(this, arrayOf(android.Manifest.permission.READ_EXTERNAL_STORAGE),1)
    } else {
        //İzin verilmiş.
        val galeriIntent = Intent(Intent.ACTION_PICK,MediaStore.Images.Media.EXTERNAL_CONTENT_URI)
        startActivityForResult(galeriIntent,2)
    }
}

override fun onRequestPermissionsResult(
    requestCode: Int,
    permissions: Array<out String>,
    grantResults: IntArray
) {
    if (requestCode==1) {
        if(grantResults.size>0 &&grantResults[0]== PackageManager.PERMISSION_GRANTED) {

            val galeriIntent = Intent(Intent.ACTION_PICK,MediaStore.Images.Media.EXTERNAL_CONTENT_URI)
            startActivityForResult(galeriIntent,2)
        }
    }

    super.onRequestPermissionsResult(requestCode, permissions, grantResults)
}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {

    if ( requestCode==2 &&  resultCode== Activity.RESULT_OK && data!=null) {
        secilenGorsel=data.data

        if (secilenGorsel!=null) {

            if (Build.VERSION.SDK_INT>= 28) {
                val source = ImageDecoder.createSource(this.contentResolver,secilenGorsel!!)
                secilenBitmap=ImageDecoder.decodeBitmap(source)
                image!!.setImageBitmap(secilenBitmap)


            }else {
                secilenBitmap= MediaStore.Images.Media.getBitmap(this.contentResolver,secilenGorsel)

                image!!.setImageBitmap(secilenBitmap)
            }

        }
    }

    super.onActivityResult(requestCode, resultCode, data)
}

logcat也没有例外。另外我是初学者，请见谅。

提前致谢。

确保您已在 AndroidManifest.xml 中添加相同的权限，如下所示。
