我一直在研究一个Android应用程序，它一直只包含1个屏幕，我决定在我的应用程序中添加一个菜单屏幕以进一步开发它，但是一旦我添加了菜单屏幕并尝试运行它，它在开场时坠毁了。

这是我的MainMenu.java文件：

package com.finalyearproject;

import android.app.Activity;
import android.os.Bundle;

public class MainMenu extends Activity
{
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mainmenu);
    }

}

这是我的'mainmenu.xml'文件：

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

    <ImageButton
        android:id="@+id/imageButton1"
        android:contentDescription="@string/app_name"
        android:layout_width="wrap_content"
        android:layout_height="453dp"
        android:maxHeight="150dp"
        android:maxWidth="150dp"
        android:scaleType="fitCenter"
        android:src="@drawable/guitarlogo" />

</LinearLayout>

最后我的AndroidManifest文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.finalyearproject"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="19"/>
    <uses-permission android:name="android.permission.RECORD_AUDIO"/>
    <uses-permission android:name="android.permission.WAKE_LOCK" />

    <application
        android:allowBackup="false"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name">

        <!-- Splash Screen Activity / Launcher -->
        <activity
            android:name="com.finalyearproject.MainMenu"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity
            android:name="com.finalyearproject.TunerActivity"
            android:label="@string/app_name" 
            android:screenOrientation="landscape" 
            android:theme="@android:style/Theme.NoTitleBar">
            </activity>
    </application>

</manifest>

如果我只保留顶级活动并将其作为“com.finalyearproject.TunerActivity”，那就打开了。只有在我尝试添加崩溃的第二个屏幕/活动时才会这样。这可能是我想念的东西，但我到处都寻求帮助！

logcat的：

logcat中的异常有点难以破译，但是当存在一组异常时，通常在Android上，最底层的是异常的根本原因。此log cat显示加载图像的OutOfMemory异常，它告诉您yoiu放在按钮上的图像太大。
