Get exact width of a textview in pixel programmatically (Android)

Question

Using android, does anybody know how to get the exact width of a textview, in pixel, before it's displayed on the screen ? (programmatically) I've search a lot on the internet but I didn't found anything working.

Thank you

Links of the post I tried :

With a Paint

With measure

With density

It was better that you had sent some code. Then we could help you more. But I think that you may use these methods:

yourText.measure(0, 0);

And then these codes:

int width = view.getMeasuredWidth();
int height = view.getMeasuredHeight();

Sorry, I just thought that this way didn't work but in fact my code was bad... Thank you very much for your quick answer – Kemix Jun 20 '16 at 19:39

I think that you should use OnGlobalLayoutListener which is usually used to find out the height and the width of views before they are drawn.

For example,

yourTextView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {

    @Override
    public void onGlobalLayout() {

      yourTextView.getWidth();

    }
});

try this.

textView.setText("your text");
textView.measure(0, 0);
textView.getMeasuredWidth();
textView.getMeasuredHeight();

As Nargess said you'd better use methods of measuring view's width and height, like code below:

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
view.measure(size.x, size.y);
int width = view.getMeasuredWidth();
int height = view.getMeasuredHeight();
