具體代碼如下：

main.xml:

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:gravity="center"    android:orientation="vertical"    android:padding="5dip" >    <Button        android:id="@+id/btnSimpleToast"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="預設" >    </Button>    <Button        android:id="@+id/btnSimpleToastWithCustomPosition"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="自訂顯示位置" >    </Button>    <Button        android:id="@+id/btnSimpleToastWithImage"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="帶圖片" >    </Button>    <Button        android:id="@+id/btnCustomToast"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="完全自訂" >    </Button>    <Button        android:id="@+id/btnRunToastFromOtherThread"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="其他線程" >    </Button></LinearLayout>

 

custom.xml:
