关于Ability的半屏、全屏等模式的配置请参考我另一篇文章：HarmonyOS(鸿蒙)应用/服务开发window_modal配置说明。这里就不在赘述了。
我在开发鸿蒙FA应用时遇到通过半屏Ability拉起全屏Ability时，如果window_modal为0，则全屏Ability会没有状态栏(状态栏为透明，能看到桌面壁纸)的情况。如果window_modal为2则会出现状态栏颜色无法自定义的问题(尤其是在dark模式下不能忍受)。
经过排查是由于需要全屏的Ability在config.json中没有配置metaData导致的：
原来的配置
{
"visible": true,
"name": "com.baidu.testApp.ConnectHelperAbility",
"configChanges": ["orientation"],
"icon": "$media:icon",
"description": "$string:empty_description",
"label": "$string:device_ConnectHelperAbility",
"type": "page",
"launchType": "standard"
}
增加
"metaData": {
"customizeData": [
{
"name": "hwc-theme",
"value": "androidhwext:style/Theme.Emui.Light.NoTitleBar"
}
]
}
最终为下面这样则可以解决
{
"visible": true,
"name": "com.baidu.testApp.ConnectHelperAbility",
"configChanges": ["orientation"],
"icon": "$media:icon",
"description": "$string:empty_description",
"label": "$string:device_ConnectHelperAbility",
"type": "page",
"launchType": "standard",
"metaData": {
"customizeData": [
{
"name": "hwc-theme",
"value": "androidhwext:style/Theme.Emui.Light.NoTitleBar"
}
]
}
}
