A checkbox is a specific type of two-states button that can be either checked or unchecked. A example usage of a checkbox inside your activity would be the following:

public class MyActivity extends Activity {
    protected void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.content_layout_id);
        final CheckBox checkBox = (CheckBox) findViewById(R.id.checkbox_id);
        if (checkBox.isChecked()) {
            checkBox.setChecked(false);
        }
    }
}
