解决方案
你在比较int。所以只需使用
if (wicketsIndia == 10) {
btnWicketIndia.setEnabled(false);
}
编辑：
int wicketsSA = 0;
Button btnWicketIndia; // DECLARE IT HERE
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
...
btnWicketIndia = findViewById(R.id.wicketIndia); // ASSIGN HERE
...
}
