这是我的主要Activity首先由应用程序启动的XML代码：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".Menu"
    android:background="@drawable/bgmenu">

<TextView android:text="@string/hello_world" android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/title" />

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Play"
    android:id="@+id/play"
    android:layout_marginTop="93dp"
    android:layout_below="@+id/title"
    android:layout_centerHorizontal="true" />

<RadioGroup
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/play"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_marginTop="62dp">

    <RadioButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Easy"
        android:id="@+id/easy"
        android:layout_gravity="center_horizontal" />
    <RadioButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Medium"
        android:id="@+id/medium"
        android:layout_gravity="center_horizontal" />
    <RadioButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hard"
        android:id="@+id/hard"
        android:layout_gravity="center_horizontal" />
</RadioGroup>


</RelativeLayout>

这是应用程序的主要java代码：

package com.example.weihao.cannongame;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.RadioGroup;
import android.widget.TextView;

/**
 * Created by Wei Hao on 7/25/2015.
 */
public class Menu extends Activity implements View.OnClickListener, RadioGroup.OnCheckedChangeListener {

    TextView title;
    RadioGroup rg;
    Button play;
    String d;

    protected void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initialize();
    }

    private void initialize() {
        title=(TextView)findViewById(R.id.title);
        rg.setOnCheckedChangeListener(this);
        play=(Button)findViewById(R.id.play);
        play.setOnClickListener(this);
    }


    @Override
    public void onClick(View v) {
        Bundle basket=new Bundle();
        basket.putString("key",d);
        Intent a=new Intent(Menu.this,mbb.class);
        a.putExtras(basket);
        startActivity(a);
    }

    @Override
    public void onCheckedChanged(RadioGroup group, int arg1) {

        switch (arg1){
            case R.id.easy:
                d ="e";
                break;
            case R.id.medium:
                d ="m";
                break;
            case R.id.hard:
                d ="h";
                break;
        }
    }


}

有人可以告诉我导致此错误的XML代码有什么问题吗？感谢。

Answer 1

在你的xml中你必须使用一个根容器元素，如LinearLayout，RelativeLayout，FrameLayout等。

您的第一个元素是TextView，它不是其他UI项的有效容器元素。

Answer 2

我不认为这些是正确的xml文件。据我所知，大多数xml文件以

开头

？xml version =“1.0”encoding =“utf-8”？

LinearLayout xmlns：android =“http://schemas.android.com/apk/res/android”

这些但我在你的代码中看不到这样的东西。请尝试插入，然后检查可能会帮助你。

Answer 3

我其实已经明白了。这是由于各种原因。首先，我使用的背景图像可能太大而导致错误。其次，我没有通过用他们的ID识别它们来正确地声明RadioGroup。
