EDIT-Moderator,随时删除此问题。问题在于我的背景图片大小,而不是实际的方向更改。
请忍受我 - 我不相信这个问题/问题已经用这个简单的术语来回答。
我有一个应用程序,其中包含多个活动和2个布局资源,每个活动具有相同的XML文件名称,存储在res / layout-land和res / layout-port中。
问题在于,当我在Nexus One上启动应用程序(我使用的是Android 2.3)时,应用程序启动时没有任何问题,但如果我尝试旋转屏幕(更改方向),它就会崩溃。为了澄清,如果我启动持有手机横向样式的Activity,应用程序会显示res / layout-land资源布局,反之亦然,但如果我尝试在运行时更改方向,则会崩溃。
我相信如果有2个XML布局,保存在-port和-land文件夹中,那么Android应该销毁活动并使用相同名称的其他布局重新创建它,对吗?
这是我的清单,如果有必要,我很乐意粘贴更多代码。
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="dominion.game"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="9" />
<application android:icon="@drawable/icon" android:label="@string/app_name" debuggable="true">
<activity android:name="dominion.game.DominionMenu"
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="dominion.game.CreateMenu"
android:label="@string/app_name">
</activity>
<activity android:name="dominion.game.AdvancedMenu"
android:label="@string/app_name">
</activity>
<activity android:name="dominion.game.ShuffleResult"
android:label="@string/app_name">
</activity>
</application>
</manifest>
这是onCreate方法的开头:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainmenu);
//...Lots of onClick listeners for the 4 buttons...
}
其余部分是动作侦听器,如果单击每个按钮,它会启动另一个活动的意图。主菜单布局对应于res / layout-land / mainmenu&amp; res / layout-port / mainmenu,至少在理论上。
我查看了DDMS错误,但没有任何链接指向代码中存在错误的地方。

从本质上讲,我的问题是:为了使自动屏幕方向更改起作用,需要采取哪些步骤?我以为我做了所有这些...
非常感谢任何帮助或建议,谢谢!
@Rahul Sharma- 这停止了崩溃,但它不是切换到其他布局,而是在不同的方向使用相同的布局。
@Asynkronos 我在2.3而不是2.1,但这肯定是一个值得考虑的有趣bug。我不认为我正在使用这些对象。
好的 - 你们会生气,但问题是我的背景图像非常接近30英寸x 30英寸。所以我把它缩小到大约7x7英寸,没有问题......
答案 0 :(得分:4)
在AndroidManifest.xml中放置
所有活动标签中的android:configChanges =“orientation | keyboardHidden”
e.g。
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="dominion.game"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="9" />
<application android:icon="@drawable/icon" android:label="@string/app_name" debuggable="true">
<activity android:name="dominion.game.DominionMenu" android:label="@string/app_name" android:configChanges="orientation|keyboardHidden">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="dominion.game.CreateMenu"
android:label="@string/app_name" android:configChanges="orientation|keyboardHidden">
</activity>
<activity android:name="dominion.game.AdvancedMenu"
android:label="@string/app_name" android:configChanges="orientation|keyboardHidden">
</activity>
<activity android:name="dominion.game.ShuffleResult"
android:label="@string/app_name" android:configChanges="orientation|keyboardHidden">
</activity>
</application>
</manifest>
希望这会有所帮助: - )

也在我的应用上发生,检查是否未在Orientation更改上创建活动。它确实与活动生命周期有关
答案 2 :(得分:0)
我的Nexus One也有类似的屏幕方向更改问题。也许您遇到了这个记录的错误?
答案 3 :(得分:0)
在您的清单中插入android:configChanges =&#34; keyboardHidden | orientation | screenSize&#34;在应用程序标签中,以克服由于方向更改而导致的崩溃这有助于我的申请。
