[英]How to set a shape's background in xml?
I just created a red circle using android shapes:我刚刚使用 android 形状创建了一个红色圆圈:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:innerRadiusRatio="4"
android:shape="ring"
android:thicknessRatio="9"
android:useLevel="false" >
<solid android:color="#FF0000" />
<size
android:height="48dip"
android:width="48dip" />
</shape>
This is really cool, but I cannot set the background color of the circle to my color.这真的很酷,但我无法将圆圈的背景颜色设置为我的颜色。 I tried android:background="#FFFFFF"
but it always appear to be black in my layout.我试过android:background="#FFFFFF"
但它在我的布局中总是看起来是黑色的。 How can I set the background of the above shape?如何设置上述形状的背景?
I think a layer-list
might help you:我认为layer-list
可能会帮助您:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" >
<solid android:color="#ffffff" />
</shape>
</item>
<item>
<shape
android:innerRadiusRatio="4"
android:shape="ring"
android:thicknessRatio="9"
android:useLevel="false" >
<solid android:color="#FF0000" />
<size
android:height="48dip"
android:width="48dip" />
</shape>
</item>
</layer-list>
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="12dp" />
<solid android:color="#ffffff" />
<stroke
android:width="1dp"
android:color="@android:color/black" />
</shape>
I am just adding helpful research as an answer.我只是添加有用的研究作为答案。 Let us suppose you have a shape
as the answer described by @GeneBo and you are looking forward to re-using that shape but with a different solid
color.让我们假设您有一个shape
作为@GeneBo所描述的答案,并且您期待重新使用该形状但具有不同的solid
。 So all you need to do in your widget is:所以你需要在你的小部件中做的是:
android:background="@drawable/your_shape_to_reuse"
android:backgroundTint="@color/new_background_color_you_need"
Ok, how about this?好的,这个怎么样?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linearLayout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#FFFFFF">
<TextView android:text="Foo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000000"
android:gravity="center"
android:background="@drawable/red_circle"/>
</LinearLayout>
</LinearLayout>
