Pop-Up Window class

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_insert);

        DisplayMetrics dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);

        int width = dm.widthPixels;
        int height = dm.heightPixels;

        getWindow().setLayout((int)(width),(int)(height*.4));

        WindowManager.LayoutParams params = getWindow().getAttributes();
        params.gravity = Gravity.BOTTOM;
       
        getWindow().setAttributes(params);

PopupWindow popup = new PopupWindow(
         popupView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
/** ... **/
popup.showAtLocation(this, Gravity.CENTER, 0, 0);

Then the only thing you need is a Listener for the Keyboard (or more general: For Window Height changes). This was actually easier than I thought - and it didn't require any special access like an Activity-object or similar. Even in my independent View-class which only knows the Context (which I didn't want to cast), I was able to accomplish that. Everything you need is only one View-object which has already been added to the layout.

final View root = this.getRootView();
root.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
    public void onGlobalLayout() {
        Rect r = new Rect();
        root.getWindowVisibleDisplayFrame(r);

        // Calculate the difference between the original height and the new height
        int heightDiff = r.height() - root.getHeight();

        // Now update the Popup's position
        // The first value is the x-axis, which stays the same.
        // Second value is the y-axis. We still want it centered, so move it up by 50% of the height
        // change
        // The thir`enter code here`d and the fourth values are default values to keep the width/height
        popup.update(0, heightDiff / 2, -1, -1);
    }
});
