Access programmatically generated CustomView objects by their ids

Question

I am trying to access an object of a custom View created in button1 from button2 this way:

final Button button1 = (Button) findViewById(R.id.generate);
button1.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {

        ObjectView object = new ObjectView(getApplicationContext());
        object.setLayoutParams(new ViewGroup.LayoutParams(
                ViewGroup.LayoutParams.WRAP_CONTENT,
                ViewGroup.LayoutParams.WRAP_CONTENT));
        object.setId(componentsIds);
        relativeLayout.addView(object);

    }
});

final Button button2 = (Button) findViewById(R.id.useComponent);
button2.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
       ObjectView object =  findViewById(componentsIds);
       object.bringToFront();
    }
});

But I get this error:

java.lang.ClassCastException: android.widget.Button cannot be cast to startup.project.views.ObjectView

Answer 1

You have added the custom view to relativeLayout. So, you have to use relativeLayout to get that custom view.

Try using

ObjectView object =  relativeLayout.findViewById(componentsIds);

Instead of

ObjectView object =  findViewById(componentsIds);
