推荐答案

看来你已经在XML犯了一些错误：

It seems you have made a few mistakes in the XML:

<manifest package="com.tabwidget">
    <application>

        1) BELOW: starting the names by "." means that
        you are implicitely extending the package prefix defined in the package 
        attribute of the manifest XML tag. 
        For example, if your package is "com.tabwidget", defining".MyActivity"
        will be interpreted as "com.tabwidget.MyActivity"
        By removing the first ".", you use an explicit notation instead:
        whatever your package is, "com.tabwidget.MyActivity" is interpreted
        as "com.tabwidget.MyActivity"
        <activity android:name=".com.tabwidget.Tab"></activity>
        <activity android:name=".com.tabwidget.TabHostProvider"></activity>
        <activity android:name=".com.tabwidget.TabView"></activity>
    </application>
</manifest>                  

2) BELOW: a manifest file should only contain one manifest XML tag:
<manifest package="com.kpbird.tabbarcontrol">
    <application>

        3) BELOW: same mistake as 1)
        <activity android:name=".com.kpbird.tabbarcontrol.TabbarView"></activity>
    </application>
</manifest>

接下来应该工作。它修复了这3个错误：

What follows should work. It fixes these 3 mistakes:

<manifest package="com.kpbird.tabbarcontrol">
    <application>
        <activity android:name="com.tabwidget.Tab"></activity>
        <activity android:name="com.tabwidget.TabHostProvider"></activity>
        <activity android:name="com.tabwidget.TabView"></activity>
        <activity android:name=".TabbarView"></activity>
    </application>
</manifest>
