强制关闭标签应用程序中的消息

我正在使用此tutorial制作标签应用程序。当我在设备上运行我的应用时，它会给我强制关闭消息。这是我的主要活动代码，我的logcat如下。我不知道我在哪里犯错。这里是代码强制关闭标签应用程序中的消息

public class TabLayoutActivity extends TabActivity { 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    Resources res = getResources(); // Resource object to get Drawables 
    TabHost tabHost = getTabHost(); // The activity TabHost 
    TabHost.TabSpec spec; // Resusable TabSpec for each tab 
    Intent intent; // Reusable Intent for each tab 

    //Artist Tab 
    intent = new Intent(this, Artists.class); 
    spec = tabHost.newTabSpec("artists").setIndicator("Artist", res.getDrawable(R.drawable.tab_icon)).setContent(intent); 
    tabHost.addTab(spec); 

    //Songs 
    intent = new Intent(this, Songs.class); 
    spec = tabHost.newTabSpec("songs").setIndicator("Songs", res.getDrawable(R.drawable.tab_icon)).setContent(intent); 
    tabHost.addTab(spec); 

    //Albums 
    intent = new Intent(this, Album.class); 
    spec = tabHost.newTabSpec("artists").setIndicator("Artist", res.getDrawable(R.drawable.tab_icon)).setContent(intent); 
    tabHost.addTab(spec); 

    tabHost.setCurrentTab(1); 
} 
}

这里是我的logcat

更新

这是我main.xml中tabhost

<TabHost xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/tabHost" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:orientation="vertical" >

第二次更新

改变tabHost到tabhost

在你main.xml，是什么的的ID TabHost？

它必须是android:id="@android:id/tabhost"。

编辑

你TabWidget必须被定义为：

<TabWidget 
     android:id="@android:id/tabs" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" />

它实际上是很容易从logcat中看到：“你TabHost必须有一个TabWidget其id属性为“android.R .id.tabs'”。

如果您发布了整个xml布局文件，这样会更容易，因此我们可以看到所有可能的错误。

您添加正确的ID在main.xml中的tabhost后logcat的？

<TabHost xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@android:id/tabhost" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent">

你misscalled该ID的问题，你必须使用@android，只需更换线

android:id="@+id/tabHost"

与

android:id="@android:id/tabhost"

我张贴的主要xml的一部分，请参阅我的更新 – 2619

我做了然后我得到了这个错误'错误：错误：没有资源发现匹配给定的名称（'id'值'@android：id/tabHost'）。 – 2619

@ al0ne我不确定id是否区分大小写，是否使用tabhost代替tabHost – Wizche

你必须导入你的package name.R;像

import package.R;

也insted这种方式我宁愿使用它来获取标签主机。就像是。 `

TabHost th = (TabHost)findViewbyid(R.id.tabhost);

和发扬其没有帮助

解决方案

问题是main.xml中的文件。在main.xml中，我应该在任何地方都使用@android:id/idname。但我用@+id/idname这是错误的。它正在工作。

你需要遵循一些主要的事情..

1.需要在manifestfile中给予权限。 2.some时间布局的高度和宽度太大，当你比较当前的模拟器或屏幕
