android - 菜单打开错误的活动

Question

我的问题是当我点击程序员它打开推特！

{见 main java 的结尾；这是我的菜单}

当我在模拟器上点击 twitter 时，它会打开程序员，反之亦然。

哪里有问题 ？

Answer 1

您最近更改了 id 吗？有时 IDE 会混淆并混淆 ID。解决这个问题的方法是清理项目并重建。

public boolean onOptionsItemSelected(MenuItem item){
    switch (item.getItemId()){
    case R.id.menunews:
        String url = "http://j.mp/rumnw";
        Intent i = new Intent(Intent.ACTION_VIEW);
        i.setData(Uri.parse(url));
        startActivity(i);
         break;

        case R.id.menutwitter:
        String rb6 = "https://twitter.com/#!/Rum_City";
        Intent r = new Intent(Intent.ACTION_VIEW);
        r.setData(Uri.parse(rb6));
        startActivity(r);
        break;

        case R.id.menuhwl:
            startActivity(new Intent("com.rum.city.HWL"));
      break;

    }


    }
return true;
