我有一个带有提交按钮的loginActivity，其中包含onClick的sendMessage（），当我尝试在模拟器上运行应用程序时，我得到的结果是：找不到资源，这是我第二个活动布局的资源。 任何帮助，将不胜感激。我试图删除R.java并重建，但这“没有用。
loginActivity
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);
}

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是相同的）
<?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>
答案 0 :(得分：3)
因此，基于此线程上发生的讨论，问题是布局资源被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。
