CodePudding user response：

It seems you're not Overriding the onCreate method. Try this:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.relative_layout);

You should try to read the warning of the xml file maybe that will help you to understand your problem, sometimes that's also happened with me but I solve these UI problems by looking and reading warning.

You should also add your code of the activity in the questions its easy to read and understand.
