如何使用XML形状drawable？(XML shape drawable not rendering desired color)

如何使用XML形状drawable？(XML shape drawable not rendering desired color)

我定义了一个drawable

<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http//schemas.android.com/apk/res/android" android:shape="rectangle"> <solid android:color="#ffffffff" /> <size android:width="60dp" android:height="40dp" /> </shape>

但是如何在layout定义中使用它？

<?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" > <ImageView android:src="@drawable/ic_title" android:layout_width="wrap_content" android:layout_height="fill_parent" /> </LinearLayout>

我仍然只看到黑色的背景。

编辑：

原来我错过了一个:在drawable xmlns声明中。 现在这个例子可以在Gingerbread设备中使用:)

I defined a drawable

<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http//schemas.android.com/apk/res/android" android:shape="rectangle"> <solid android:color="#ffffffff" /> <size android:width="60dp" android:height="40dp" /> </shape>

But how to use it in the layout definition?

<?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" > <ImageView android:src="@drawable/ic_title" android:layout_width="wrap_content" android:layout_height="fill_parent" /> </LinearLayout>

I still see only black background.

Edited:

It turned out I missed one : in the drawable xmlns declaration. Now this example works in the Gingerbread device :)

最满意答案

我有一个类似的问题，发现如果你删除大小的定义，它的工作原因有些。

去掉：

<size android:width="60dp" android:height="40dp" />

从形状。

让我知道如果这个工作！

I had a similar problem and found that if you remove the size definition, it works for some reason.

Remove:

<size android:width="60dp" android:height="40dp" />

from the shape.

Let me know if this works!
