今天学习了一下 TabHost以前也是一知半解 今天想系统了解下 JAVA代码非常简单 xml只是2个简单布局 这里就不列出了

学习过程中遇到了这样的错误 在setContent里 我添入的是 layout的ID 导致运行出错
Could not create tab content because could not find view with id 2130903041
这里是我的不仔细 查了很久发现原来 这里serContent()里边的要是视图的id，比如
LinearLayout的ID 这样的，结果把2个xml文件里的Layout加上id再载入就OK了，这里要
反思一下 为什么会出现这种细节错误
底部标签的实现：
其实也很简单，就是xml里改一下 2个属性
<span class="tag"><LinearLayout</span><span class="pln"> </span><span class="atn">android:layout_width</span><span class="pun">=</span><span class="atv">"match_parent"</span><span class="pln"> </span><span class="atn">android:layout_height</span><span class="pun">=</span><span class="atv">"match_parent"</span><span class="pln"> </span><span class="atn">android:orientation</span><span class="pun">=</span><span class="atv">"vertical"</span><span class="pln"> </span><span class="tag">></span><span class="pln"> </span><span class="tag"><FrameLayout</span><span class="pln"> </span><span class="atn">android:id</span><span class="pun">=</span><span class="atv">"@android:id/tabcontent"</span><span class="pln"> </span><span class="atn">android:layout_width</span><span class="pun">=</span><span class="atv">"match_parent"</span><span class="pln"> </span><span class="atn">android:layout_height</span><span class="pun">=</span><span class="atv">"match_parent"</span><span class="pln"> </span><span class="atn">android:layout_weight</span><span class="pun">=</span><span class="atv">"1"</span><span class="pln"> </span><span class="tag">/></span><span class="pln"> </span><span class="tag"><TabWidget</span><span class="pln"> </span><span class="atn">android:id</span><span class="pun">=</span><span class="atv">"@android:id/tabs"</span><span class="pln"> </span><span class="atn">android:layout_width</span><span class="pun">=</span><span class="atv">"match_parent"</span><span class="pln"> </span><span class="atn">android:layout_height</span><span class="pun">=</span><span class="atv">"wrap_content"</span><span class="pln"> </span><span class="tag">/></span><span class="pln"> </span><span class="tag"></LinearLayout></span> |
这里FrameLayout要写在上边 weight要设为1 然后还要在外边加一层垂直布局的LinearLayout
