if语句中的Android setContentView

Question

这是上一个问题的后续内容

Android setContentView not being applied

在这个if语句中我希望能够setContentView当我将它们都设置为R.layout.introact if语句有效但在else部分我希望它加载不同的布局但是当我将它更改为R. layout.introact2它强制关闭应用程序

继承人的代码

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        String leagueCount = getIntent().getStringExtra("leagueCount");
        Log.d("lc", "Received league count of:"+ leagueCount);

        if ("2".equals(leagueCount)){
            setContentView(R.layout.introact);
            Log.d("lc", "Using league count of 2 layout");
        }else{
            setContentView(R.layout.introact);
            Log.d("lc", "Using default layout");
        }
