本文通过实例演示如何使用嵌套LinearLayout实现复杂的界面布局。详细介绍了水平和垂直布局中权重的应用，以及如何设置背景颜色和文字居中显示。

如果看了我上面的两个Layout布局的代码的话对这个肯定感觉不到什么难度，那我就先把结果图贴出来，我是先看了成果自己写的，嵌套中有三个LinearLayout。这个有点像Div+Css...不大复杂。贴图咯。

如果大家已经把上面的写出来就不要看下面的代码了。这一节只是一个总结，下一节比较精彩。

main.xml

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation = "vertical" android:layout_width = "fill_parent" android:layout_height = "fill_parent" > <LinearLayout android:orientation = "horizontal" android:layout_width = "fill_parent" android:layout_height = "fill_parent" android:layout_weight = "1"> <TextView android:text = "red" android:gravity = "center_horizontal" android:background = "#aa0000" android:layout_width = "wrap_content" android:layout_height = "fill_parent" android:layout_weight = "1"/> <TextView android:text = "green" android:gravity = "center_horizontal" android:background = "#00aa00" android:layout_width = "wrap_content" android:layout_height = "fill_parent" android:layout_weight = "1"/> <TextView android:text = "blue" android:gravity = "center_horizontal" android:background = "#0000aa" android:layout_width = "wrap_content" android:layout_height = "fill_parent" android:layout_weight = "1"/> <TextView android:text = "yellow" android:gravity = "center_horizontal" android:background = "#aaaa00" android:layout_width = "wrap_content" android:layout_height = "fill_parent" android:layout_weight = "1"/> </LinearLayout> <LinearLayout android:orientation = "vertical" android:layout_width = "fill_parent" android:layout_height = "fill_parent" android:layout_weight = "1"> <TextView android:text = "row one" android:textSize = "15pt" android:layout_width = "fill_parent" android:layout_height = "wrap_content" android:layout_weight = "1"/> <TextView android:text = "row two" android:textSize = "15pt" android:layout_width = "fill_parent" android:layout_height = "wrap_content" android:layout_weight = "1"/> <TextView android:text = "row three" android:textSize = "15pt" android:layout_width = "fill_parent" android:layout_height = "wrap_content" android:layout_weight = "1"/> <TextView android:text = "row four" android:textSize = "15pt" android:layout_width = "fill_parent" android:layout_height = "wrap_content" android:layout_weight = "1"/> </LinearLayout> </LinearLayout>
