我正在尝试实现导航抽屉这是我的代码，我在运行应用程序时遇到错误。
这是日食问题的错误。
描述资源路径位置类型 FragmentTransaction类型中的方法replace（int，Fragment）不适用于参数（int，Fragment）MainActivity.java / NavigationDrawer / src / com / example / navigationdrawer line 198 Java Problem。

这是片段
package com.example.testnav;
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class FragmentOne extends Fragment {
public FragmentOne(){}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_one, container, false);
return rootView;
}
}
这是我的xml
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- The main content view -->
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- The navigation drawer -->
<ListView android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="#666"
android:dividerHeight="1dp"
android:background="#333"
android:paddingLeft="15sp"
android:paddingRight="15sp"
/>
</android.support.v4.widget.DrawerLayout>

尝试使用FragmentActivity代替Activity
public class MainActivity extends FragmentActivity
和
default:
fragment = new FragmentOne();
break;
答案 1 :(得分：0)
我得到了同样的错误。需要修改拖曳地点，如下所示。
首先，使用FragmentActivity
public class MainActivity extends FragmentActivity
其次，将getFragmentManager更改为getSupportFragmentManager：
FragmentManager fragmentManager = getSupportFragmentManager();
