Description

How to reproduce:

Create a LinearLayout and set it as content view of an Activity
Add an android.widget.Button to the Layout.
Instantiate a QtQuickView, set layout params and loadComponent(). The component may have any kind of component that handles touch inputs. (MouseArea, Button, ...)
Add the QtQuickView to the same layout

Expected behavior:

The user touches an area that is intended to handle user inputs, and see UI changes or log outputs.

Actual behavior:

The component does not react to user inputs.

Environment:

Android 13 emulator, x86_64

More info:

If the QtQuickView gets added to the layout before the Button, the QtQuickView gets touch inputs as expected. The Button also reacts to touch inputs.

 // Create a LinearLayout
        layout = new LinearLayout(this);
        layout.setOrientation(LinearLayout.VERTICAL);        
        TextView textView = new TextView(this);
        textView.setText("Hello World");        
        Button button = new Button(this);
        
        quickView = new QtQuickView(this);
        mainQml = new Main();
        quickView.loadComponent(mainQml);        
        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(400, 400);
        
        //in the following order it can handle touches
        //layout.addView(quickView, params);
        //layout.addView(textView);
        //layout.addView(button);
        //layout.addView(new Button(this)); 

 //but not the following order it can handle touches         
layout.addView(textView);
layout.addView(button);
layout.addView(new Button(this)); 
layout.addView(quickView, params);
