“Project”
窗口,点击 “entry > src > main > resources > base > layout”
,打开“ability_main.xml”
文件。“ability_main.xml”
文件中创建一个文本和一个按钮,示例代码如下:<?xml version="1.0" encoding="utf-8"?> <DependentLayout xmlns:ohos="http://schemas.huawei.com/res/ohos" ohos:width="match_parent" ohos:height="match_parent" ohos:background_element="#FFFFFF"> <Text ohos:id="$+id:text" ohos:width="match_content" ohos:height="match_content" ohos:text="Hello World" ohos:text_color="#000000" ohos:text_size="32fp" ohos:center_in_parent="true"/> <Button ohos:id="$+id:button" ohos:width="match_content" ohos:height="match_content" ohos:text="Next" ohos:text_size="19fp" ohos:text_color="#FFFFFF" ohos:top_padding="8vp" ohos:bottom_padding="8vp" ohos:right_padding="70vp" ohos:left_padding="70vp" ohos:background_element="$graphic:background_button" ohos:center_in_parent="true" ohos:align_parent_bottom="true" ohos:bottom_margin="40vp"/> </DependentLayout>
“background_button”
来显示的。右键点击“graphic”
文件夹,选择“New > File”
,命名为“background_button.xml”
。“background_button.xml”
的示例代码如下(如果DevEco Studio提示xmlns字段错误,请忽略,不影响后续操作):
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:ohos="http://schemas.huawei.com/res/ohos"
ohos:shape="rectangle">
<corners
ohos:radius="100"/>
<solid
ohos:color="#007DFF"/>
</shape>
“Project”
窗口,选择“entry > src > main > java > com.example.myapplication > slice”
,打开“MainAbilitySlice.java”
文件,使用setUIContent
方法加载XML
布局,示例代码如下:package com.example.myapplication.slice; import com.example.myapplication.ResourceTable; import ohos.aafwk.ability.AbilitySlice; import ohos.aafwk.content.Intent; public class MainAbilitySlice extends AbilitySlice { @Override public void onStart(Intent intent) { super.onStart(intent); super.setUIContent(ResourceTable.Layout_ability_main); // 加载XML布局 } @Override public void onActive() { super.onActive(); } @Override public void onForeground(Intent intent) { super.onForeground(intent); } }
说明:
如果DevEco Studio提示Layout_ability_main错误,点击菜单栏的“Build”,选择“Build App(s)/Hap(s) > Build Debug Hap(s) ”,即可消除报错。
