Java 错误：android.view.InflateException:二进制XML文件行#8:二进制XML文件行#8:膨胀类片段时出错

我正在尝试创建一个游戏，在这个游戏中，你可以与连接到一个房间的一群人聊天。我想在片段中进行聊天，我希望它在横向模式下位于UI（实际游戏活动）的右侧。我在片段布局和EditText中使用ListView。我看到了各种各样的答案，但找不到解决办法。 我正在使用firebase实时数据库在listview中插入数据。 感谢您的帮助

主要游戏活动：

package com.example.lrmah.rajaranichorpolice;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import com.example.lrmah.rajaranichorpolice.Chat.chatFragmentActivity;

public class mainGameActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main_game);

        Bundle bundle=new Bundle();
        bundle.putString("name", "From Activity");
        //set Fragmentclass Arguments
        chatFragmentActivity fragobj=new chatFragmentActivity();
        fragobj.setArguments(bundle);
    }
}

您应该首先对布局进行

充气

以获得片段的视图，然后尝试在

onCreateView

中访问视图

initViews（）

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {

    getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    final View view = inflater.inflate(R.layout.chat_fragment_layout, container, false);
    initViews(view);
    return view;
}

因此，请尝试将其修改为：

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.chat_fragment_layout, container, false);
    initViews();
    getActivity().setRequestedOrientation(
            ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    return rootView;
}

---

在

chatFragmentActivity

中，在

onCreateView

方法完成之前，您不能调用

initViews（）

，因为

getView（）

将返回

null

。您可以重写

onCreateView

方法，并将视图传递给

initViews

类似的内容：

public void initViews(final View view) {
    mProgressBar = (ProgressBar) view.findViewById(R.id.progressBar);
    mPhotoPickerButton = (ImageButton) view.findViewById(R.id.photoPickerButton);
    mMessageEditText = (EditText) view.findViewById(R.id.messageEditText);
    mSendButton = (Button) view.findViewById(R.id.sendButton);
    mProgressBar.setVisibility(ProgressBar.INVISIBLE);
}

然后将视图传递到

onCreateView

中的

initViews

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {

    getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    final View view = inflater.inflate(R.layout.chat_fragment_layout, container, false);
    initViews(view);
    return view;
}

根据我的说法，你可以尝试用其他方法来膨胀你的碎片，比如：

在主活动布局中为片段添加容器。你可以简单地用这个替换

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/black">

<FrameLayout
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />


<Button
    android:layout_width="50dp"
    android:layout_height="50dp" />
</RelativeLayout>

而且你还面临着列表id的问题，你可以参考这个

希望这会有所帮助。

那么可能是因为

rootView

在

getView（）方法中不可用，直到
onCreateView
返回。我建议尝试上面的@MarkusPenguin解决方案谢谢您的快速响应。容器属于哪个类？（在container=（FrameLayout）findViewById（R.id.container）中；此onCreate（）方法属于代码中作为mainGameActivity的main活动。我按照您的建议执行了操作，并收到一条错误消息：“java.lang.RuntimeException:内容具有id属性为'android.R.id.list'的视图，它不是ListView类”我在我的回答的最后一行提到了这个错误的解决方案“而且你还面临列表id的问题，你可以参考这个链接”检查链接……我用fragment only扩展了我的片段，而不是ListFragment，你可以根据你的要求选择。谢谢你Raghav Sharma。它很有魅力。我把它改为fragment only，然后初始化了我的列表，解决了这个问题。谢谢你的快速响应。我已经完成了你说的，我正在准备g同样的错误。
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {

    getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    final View view = inflater.inflate(R.layout.chat_fragment_layout, container, false);
    initViews(view);
    return view;
