在 uni-app 中,可以通过 Native.js 实现安卓本地通知,具体步骤如下:
1. 在 App.vue 文件中,监听应用启动事件,调用 Native 模块中的 startForeground 方法开启前台服务:
```javascript
export default {
onLaunch() {
const nativeModule = uni.requireNativePlugin("NativeModule");
nativeModule.startForeground();
}
}
```
2. 在 Native 模块中,实现 startForeground 方法,并在该方法中创建通知渠道和通知:
```javascript
const Context = require("@android/context");
const Notification = require("@android/app/Notification");
const NotificationManagerCompat = require("@android/app/NotificationManagerCompat");
const NotificationChannel = require("@android/app/NotificationChannel");
function startForeground() {
const service = getContext().getService();
const channel = new NotificationChannel("channel_id", "channel_name", NotificationManagerCompat.IMPORTANCE_HIGH);
const notificationManager = NotificationManagerCompat.from(Context);
const notification = new Notification.Builder(Context, "channel_id")
.setSmallIcon(android.R.drawable.ic_dialog_info)
.setContentTitle("Foreground Service")
.setContentText("Service is running in foreground")
.build();
service.startForeground(1, notification);
}
```
3. 在 Native 模块中,实现 showNotification 方法,用于创建本地通知:
```javascript
function showNotification(title, content) {
const notificationManager = NotificationManagerCompat.from(Context);
const notification = new Notification.Builder(Context, "channel_id")
.setSmallIcon(android.R.drawable.ic_dialog_info)
.setContentTitle(title)
.setContentText(content)
.build();
notificationManager.notify(1, notification);
}
```
其中,第一个参数为通知的 ID,第二个参数为 Notification 对象。
4. 在 App.vue 文件中,调用 Native 模块中的 showNotification 方法创建本地通知:
```javascript
export default {
methods: {
showLocalNotification() {
const nativeModule = uni.requireNativePlugin("NativeModule");
nativeModule.showNotification("Local Notification", "This is a local notification");
}
}
}
```
这样就可以通过 Native.js 实现安卓本地通知了。
