Question

I am facing a problem when gets height/width of TextView.

My code :

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    TextView tv1 = (TextView)findViewById(R.id.textview1);
    int h1 = tv1.getHeight();
    TextView tv2 = (TextView)findViewById(R.id.textview2);
    int h2 = tv2.getHeight();
}

h1 is height of textview1
h2 is height of textview2

These h1 and h2 are always equal to 0.

What is wrong here ?

Please advice.

Thanks.

Answer 1

View.getWidth()/View.getHeight() won’t give you a meaningful answer until the view has been measured.
Read about how android draws views here.
See this thread to get an idea of when the measured dimensions will be available.
