在eclipse下利用android开发插件,来写基于xml-based的图形界面很简单也很方便.

在outline或效果界面中选中所编辑的节点(View),接着在下边的Property窗口下其对应的属性列表中填写自定义的属性值.

结果出来的Layout文件如下(可以查看如下文件来填写节点属性值-在上面的步骤)

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    >    <TableLayout android:id="@+id/sTableLayout"    android:layout_width="wrap_content"    android:layout_height="wrap_content">    <TableRow >    <ImageView android:background="@drawable/bg1"/>    <EditText/>    </TableRow>    <TableRow>    <ImageView android:background="@drawable/bg2"/>    <EditText/>    </TableRow>    </TableLayout>    <Button android:id="@+id/exitButton"    android:text="退出"    android:layout_width="wrap_content"    android:layout_height="wrap_content"     android:layout_below="@+id/sTableLayout"     android:layout_marginTop="20sp"/></RelativeLayout>

相对布局的使用只有注意到控件ID就不难理解与编码

代码:
