Did it! Thanks Romain! :)
For other people having the same trouble, the trick is to use the
onWindowFocusChanged(boolean hasWindowFocus) class like in this
example :
public void onWindowFocusChanged(boolean hasWindowFocus) {
int maxButton; // I save the biggest button width in this variable
Button testButton = (Button)findViewById(R.id.test); // button 1
Button testButton2 = (Button)findViewById(R.id.test2); // button 2
Button testButton3 = (Button)findViewById(R.id.test3); // button 3
maxButton=testButton.getWidth(); // I put button 1's width into
maxButton
if(testButton2.getWidth() > maxButton) { // If button 2's width is
bigger
maxButton = testButton2.getWidth(); // maxButton gets button 2's width
testButton3.setText("Button 2 is bigger than button 1!");
}
else
testButton3.setText("Button 1 is bigger than button 2!");
}
