1、
<include layout="@layout/main_header" />
<net.oschina.app.widget.ScrollLayout
android:id="@+id/main_scrolllayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1">
<include layout="@layout/frame_news" />
<include layout="@layout/frame_question" />
<include layout="@layout/frame_tweet" />
<include layout="@layout/frame_active" />
</net.oschina.app.widget.ScrollLayout>
通过include其他的layout拆分了设计
是如何在自定义控件里又包含了其他的layout？
android:layout_weight="1" 的作用是指定控件所占空间的权重，默认为0，即为怎么设定怎么显示
而设为1说明是平摊控件，这样两个android:layout_width="fill_parent" 的控件会左右各占一半空间
2.
<Button
android:id="@+id/frame_btn_news_lastest"
style="@style/frame_button"
android:text="@string/frame_title_news_lastest"/>
<style name="frame_button">
<item name="android:layout_width">fill_parent</item>
<item name="android:layout_height">fill_parent</item>
<item name="android:layout_weight">1</item>
<item name="android:background">@drawable/frame_button_bg</item>
<item name="android:textColor">@color/frame_button_text_light</item>
</style> <selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="true" android:drawable="@drawable/frame_button_n" />
<item android:state_enabled="false" android:drawable="@drawable/frame_button_p" />
</selector> <selector
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="true" android:color="@color/frame_button_text_nor" />
<item android:state_enabled="false" android:color="@color/frame_button_text_select" />
<item android:color="@color/frame_button_text_nor" />
</selector> 对用一些多次重用的属性（比如在一组按钮中），可以设为一个style供调用style="@style/frame_button" ，
按钮的背景可以设置为一个selector，使其在不同的状态下有不同的图像，文字的颜色也可以这样
3.
<ImageView android:layout_width="wrap_content" android:layout_height="fill_parent" android:background="@drawable/frame_button_cutline"/>
仿TAB按钮之间的分隔效果是通过贴图实现的
4，
工具栏的TAB效果是用按钮模拟出来的（这里用RadioButton不知道有何深意，但是却没用RadioButtonGroup）
通过数组来操作，统一操作
/**
* 初始化水平滚动翻页
*/
private void initPageScroll()
{
mScrollLayout = (ScrollLayout) findViewById(R.id.main_scrolllayout);
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.main_linearlayout_footer);
mHeadTitles = getResources().getStringArray(R.array.head_titles);
mViewCount = mScrollLayout.getChildCount();
mButtons = new RadioButton[mViewCount];
for(int i = 0; i < mViewCount; i++)
{
mButtons[i] = (RadioButton) linearLayout.getChildAt(i*2);
获取底部工具栏的单选按钮，存入数组中，所以通过private RadioButton fbNews一直无法找到处理操作的函数）
mButtons[i].setTag(i);
mButtons[i].setChecked(false);
