I have some text that will be put in a TextView
. I did that using setText()
.
Now I need to find the number of lines or height the text occupies
Because this size is known only after the layout is finished, one way is to create a custom text view and use onSizeChanged method. Another way is this:
final TextView tv = (TextView) findViewById(R.id.myTextView);
ViewTreeObserver vto = tv.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
Toast.makeText(MyActivity.this, tv.getWidth() + " x " + tv.getHeight(), Toast.LENGTH_LONG).show();
tv.getViewTreeObserver().removeGlobalOnLayoutListener(this);
}
});
This code I've found here: How to retrieve the dimensions of a view?
