通过UIAbility处理通知跳转事件时，可使用onCreate或onNewWant的LaunchParam.launchReasonMessage字段是否为'ReasonMessage_Notification'判断。
onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {
try {
this.context.getApplicationContext().setColorMode(ConfigurationConstant.ColorMode.COLOR_MODE_NOT_SET);
} catch (err) {
hilog.error(DOMAIN, 'testTag', 'Failed to set colorMode. Cause: %{public}s', JSON.stringify(err));
}
hilog.info(DOMAIN, 'testTag', '%{public}s', 'Ability onCreate');
if (launchParam.launchReasonMessage === 'ReasonMessage_Notification') {
// 识别为被通知拉起
console.info('被拉起原因：通知');
}
}
onNewWant(want: Want, launchParam: AbilityConstant.LaunchParam): void {
if (launchParam.launchReasonMessage === 'ReasonMessage_Notification') {
// 识别为被通知拉起
console.info('被拉起原因：通知');
}
} 完整示例参考如下：
EntryAbility:
import { AbilityConstant, ConfigurationConstant, UIAbility, Want } from '@kit.AbilityKit';
import { hilog } from '@kit.PerformanceAnalysisKit';
import { window } from '@kit.ArkUI';
const DOMAIN = 0x0000;
export default class EntryAbility extends UIAbility {
onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void {
try {
this.context.getApplicationContext().setColorMode(ConfigurationConstant.ColorMode.COLOR_MODE_NOT_SET);
} catch (err) {
hilog.error(DOMAIN, 'testTag', 'Failed to set colorMode. Cause: %{public}s', JSON.stringify(err));
}
hilog.info(DOMAIN, 'testTag', '%{public}s', 'Ability onCreate');
if (launchParam.launchReasonMessage === 'ReasonMessage_Notification') {
// 识别为被通知拉起
console.info('被拉起原因：通知');
}
}
onNewWant(want: Want, launchParam: AbilityConstant.LaunchParam): void {
if (launchParam.launchReasonMessage === 'ReasonMessage_Notification') {
// 识别为被通知拉起
console.info('被拉起原因：通知');
}
}
onDestroy(): void {
hilog.info(DOMAIN, 'testTag', '%{public}s', 'Ability onDestroy');
}
onWindowStageCreate(windowStage: window.WindowStage): void {
// Main window is created, set main page for this ability
hilog.info(DOMAIN, 'testTag', '%{public}s', 'Ability onWindowStageCreate');
windowStage.loadContent('pages/Index', (err) => {
if (err.code) {
hilog.error(DOMAIN, 'testTag', 'Failed to load the content. Cause: %{public}s', JSON.stringify(err));
return;
}
hilog.info(DOMAIN, 'testTag', 'Succeeded in loading the content.');
});
}
onWindowStageDestroy(): void {
// Main window is destroyed, release UI related resources
hilog.info(DOMAIN, 'testTag', '%{public}s', 'Ability onWindowStageDestroy');
}
onForeground(): void {
// Ability has brought to foreground
hilog.info(DOMAIN, 'testTag', '%{public}s', 'Ability onForeground');
}
onBackground(): void {
// Ability has back to background
hilog.info(DOMAIN, 'testTag', '%{public}s', 'Ability onBackground');
}
