【JAVA UI】abilitySlice或ability以Action方式跳转

【JAVA UI】HarmonyOS 定位的功能基本实现

代码实现

• xml布局绘画

在xml布局绘制三个Text组件分别为“百度地图”，“腾讯地图”，“高德地图”，代码如下

<DirectionalLayout
    xmlns:ohos="http://schemas.huawei.com/res/ohos"
    ohos:height="match_parent"
    ohos:width="match_parent"
    ohos:alignment="center"
    ohos:orientation="vertical">
 
 
 
    <Text
        ohos:id="$+id:start_baidu1"
        ohos:height="100vp"
        ohos:width="match_parent"
        ohos:text_alignment="center"
        ohos:background_element="$graphic:background_ability_main"
        ohos:layout_alignment="horizontal_center"
        ohos:text="百度地图"
        ohos:text_size="40vp"
        />
 
    <Text
        ohos:id="$+id:start_tongxun"
        ohos:height="100vp"
        ohos:width="match_parent"
        ohos:text_alignment="center"
        ohos:background_element="#ed6161"
        ohos:layout_alignment="horizontal_center"
        ohos:text="腾讯地图"
        ohos:text_size="40vp"
        />
 
    <Text
        ohos:id="$+id:start_gaode"
        ohos:height="100vp"
        ohos:width="match_parent"
        ohos:text_alignment="center"
        ohos:background_element="$graphic:background_ability_main"
        ohos:layout_alignment="horizontal_center"
        ohos:text="高德地图"
        ohos:text_size="40vp"
        />
