Get Measure Height Of A Textview Without Add To The View Hierarchy

I get following requirement. I need to build a tree with leaves placed left and right, from the screen top to the bottom. I can not put the leaves in a ListView because tow leaves

Solution 1:

Create textView, set LayoutParams, set text, call it's measure method and read measured values. BTW you can measure text, not textView (see StaticLayout).

I think you better create your custom layout where you can implement all your "leaves measument" algorithms. Check this lesson. Custom layout is very easy )

Solution 2:

Use this for calculate height and width your textview

    textView.getViewTreeObserver().addOnGlobalLayoutListener(
            new OnGlobalLayoutListener() {
                publicvoidonGlobalLayout() {
                 h=textView.getHeight();
                 w=textView.getWidth();
        textView.getViewTreeObserver()
                            .removeGlobalOnLayoutListener(this);
    }

But in xml do not assign textview as a wrap content. Because it will give you value 0.
