android Intent 参数传值实例

前端代码：

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">
	<Button android:id="@ id/button1" android:layout_width="wrap_content"
		android:layout_height="wrap_content" android:text="button1" />
	<Button android:id="@ id/button2" android:layout_width="wrap_content"
		android:layout_height="wrap_content" android:text="button2" />
	<Button android:id="@ id/button3" android:layout_width="wrap_content"
		android:layout_height="wrap_content" android:text="button3" />
</LinearLayout>

second.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="wrap_content" android:layout_height="wrap_content">
	<Button android:id="@ id/button2" android:layout_width="wrap_content"
		android:layout_height="wrap_content" android:text="button2" />
</LinearLayout>

third.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="wrap_content" android:layout_height="wrap_content">
	<Button android:id="@ id/button3" android:layout_width="wrap_content"
		android:layout_height="wrap_content" android:text="button3" />
</LinearLayout>
