android - 尝试切换到选项卡式 fragment Activity 时出现布局 "resource not found"异常

Question

我有一个带有提交按钮的登录 Activity ，该按钮具有用于 onClick 的 sendMessage() ，当我尝试在模拟器上运行该应用程序时，我得到的原因是:找不到资源，这是我的第二个 Activity 的布局的资源。 任何帮助，将不胜感激。我尝试删除 R.java 并重建，但这没有帮助。

登录 Activity

public class Login extends Activity {
    public final static String USERNAME = "com.example.seattleivg.USERNAME";

    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);
    }

    public void sendMessage(View view) {
        Intent intent = new Intent(this, TabActionBarHomeActivity.class);
        //get username from usernameText field
        //EditText editText = (EditText) findViewById(R.id.usernameText);
        //String message = editText.getText().toString();
        //key-value pair to pass between activities
        //intent.putExtra(USERNAME, message);
        startActivity(intent);
    }

清理项目后更新了 LogCat 文件

编辑 AndrologyHomeFragment.java(EmbryologyHomeFragment.java与各自的xml相同)

public class AndrologyHomeFragment extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState){
        return (LinearLayout) inflater.inflate(R.layout.andrology_home, container, false);
    }
}

andrology_home.xml(embryology_home.xml 相同)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/andrology_home"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <TextView
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:text="andrology layout" />


</LinearLayout>

因此，根据此线程上发生的讨论，问题是布局资源放置在错误的文件夹中，这是开发人员网站中解释如何为特定设备配置提供资源的部分。
