harmonyos鸿蒙,HarmonyOS鸿蒙之设置圆角
1、同时设置四个角
a、静态设置
graphic下新建 background_supertext_red.xml
ohos:shape="rectangle">
ohos:color="$color:white"/>
ohos:width="2"
ohos:color="$color:red"/>
ohos:radius="20"/>
layout.xml中引用
ohos:height="50vp"
ohos:width="match_parent"
ohos:background_element="$graphic:background_supertext_red"
ohos:margin="20vp"
ohos:text="按钮"
ohos:text_size="20fp"/>
b、动态设置，不在layout.xml中通过ohos:background_element引用，通过代码动态设置
Button button = (Button) findComponentById(ResourceTable.Id_btn);
button.setBackGround(ResourceTable.Graphic_background_supertext_red);
或者
Button button = (Button) findComponentById(ResourceTable.Id_btn);
ShapeElement element = new ShapeElement(getContext(),
ResourceTable.Graphic_background_supertext_red);
button.setBackground(element);
2、单独设置四个角中的某个圆角
element.setCornerRadiiArray(new float[]{
tlRadius, tlRadius,
trRadius, trRadius,
brRadius, brRadius,
blRadius, blRadius
});
举个例子吧(设置左上与右上圆角)：
ohos:height="50vp"
ohos:width="match_parent"
ohos:background_element="$graphic:background_supertext_red"
ohos:margin="20vp"
ohos:text="按钮"
ohos:text_size="20fp"/>
background_supertext_red.xml中不在使用corners圆角属性
ohos:shape="rectangle">
ohos:color="$color:white"/>
ohos:width="2"
ohos:color="$color:red"/>
然后通过代码动态设置单独圆角，比如上圆角
Button button = (Button) findComponentById(ResourceTable.Id_btn);
ShapeElement element = new ShapeElement(getContext(),
ResourceTable.Graphic_background_supertext_red);
element.setCornerRadiiArray(new float[]{
20f, 20f,
20f, 20f,
0f, 0f,
0f, 0f
});
button.setBackground(element);
