AlertDialog with setView is too tall-CodePudding

I'm making an app and want to integrate donations since it's free and has no ads. I'm trying to add an AlertDialog with a QR code and a positive button. When I use this code, though, the AlertDialog is too tall (looks ugly), and you can't press the button. What can I do? Thanks.

            val inflater = this.layoutInflater
            val dialogView = inflater.inflate(R.layout.btc_layout, null)
            val builder: AlertDialog? =
                AlertDialog.Builder(this).setMessage("Click copy to copy the Bitcoin address to your clipboard")

                    .setPositiveButton("copy"){ dialog, which ->
                        val clipboardManager = getSystemService(Context.CLIPBOARD_SERVICE) as ClipboardManager
                        val address = ClipData.newPlainText("text", "3KekRCkMo7pC9Rd1u5JtQQPdxnXD1cUfnM")
                        clipboardManager.setPrimaryClip(address)

                        Toast.makeText(
                            this@donations,
                            "copied!",
                            Toast.LENGTH_SHORT
                        ).show()

                    }.setView(dialogView).show()

this is btc_layout:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/btc">
    </ImageView>

</androidx.constraintlayout.widget.ConstraintLayout>

I figured it out. I just set the layout_gravity in the XML file to center, and changed the width and height to match the AlertDialog.

CodePudding user response：

It is not your code, it is the ImageView by itself

A possible issue (I have personally had the same issue), I believe that the ImageView tends to set the height to be parent, no matter what is declared. I would try specify the height and width of the ImageView to something like like 100dp by 100dp or larger or to your specifications.
