Question

我是程序员的新手，我得到了简单的代码，但它不适合我。

我得到了带有列表的简单菜单，以及带有意图的功能来进行其他活动。

代码：

 @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle item selection
        switch (item.getItemId()) {
            case R.id.action_click:
                ClickerActivity();
                return true;
            case R.id.action_upgrades:
                UpgradesActivity();
                return true;
            case R.id.action_warehouse:
                WarehouseActivity();
                return true;
            case R.id.action_postservice:
                PostServiceActivity();
                return true;
            case R.id.action_shop:
                ShopActivity();
                return true;
            case R.id.action_market:
                //MarketActivity();
                return true;
            case R.id.action_garage:
                GarageActivity();
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }
    }

    public void ClickerActivity(View view){
        Intent intent = new Intent(this, MainActivity.class);
        startActivity(intent);
    }

    public void UpgradesActivity(View view){
        Intent intent = new Intent(this, UpgradesActivity.class);
        startActivity(intent);
    }

Answer 1

因为您的ClickerActivity函数需要View输入，在这种情况下不需要，所以删除它

如果您在使用ClickerActivity的{{1}}中使用XML，则更好的选择就是在切换案例中复制OnClick代码

使用此

intent

而不是

public void ClickerActivity(){
        Intent intent = new Intent(this, MainActivity.class);
        startActivity(intent);
    }

Answer 2

你也可以找到这样的方式..

 @Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle item selection
    switch (item.getItemId()) {
        case R.id.action_click:
            Intent intent = new Intent(this, Activity.class);
            startActivity(intent);
            return true;
        case R.id.action_upgrades:
            Intent intent = new Intent(this, UpgradesActivity.class);
            startActivity(intent);
            return true;
        case R.id.action_warehouse:
            WarehouseActivity();
            return true;
        case R.id.action_postservice:
            PostServiceActivity();
            return true;
        case R.id.action_shop:
            ShopActivity();
            return true;
        case R.id.action_market:
            //MarketActivity();
            return true;
        case R.id.action_garage:
            GarageActivity();
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}
