如何在下载通知的contentView中添加动画图标？

// Step 1: 创建自定义布局文件 custom_notification_layout.xml

<!-- custom_notification_layout.xml -->
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    
    <!-- 其他通知内容组件 -->

    <ImageView
        android:id="@+id/animation_icon"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/animation_frame_1"
        android:visibility="gone" />

</RelativeLayout>

// Step 2-10: 在代码中实现添加动画图标的通知

// 获取通知的 RemoteViews 对象
RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.custom_notification_layout);

// 设置初始状态下动画图标不可见
remoteViews.setViewVisibility(R.id.animation_icon, View.GONE);

// 设置初始帧的图像
Bitmap initialFrameBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.animation_frame_1);
remoteViews.setImageViewBitmap(R.id.animation_icon, initialFrameBitmap);

// 设置动画图标可见
remoteViews.setViewVisibility(R.id.animation_icon, View.VISIBLE);

// 使用 Handler 或 TimerTask 等机制，定时更新动画图标的显示帧
final Handler handler = new Handler();
Timer timer = new Timer();
TimerTask task = new TimerTask() {
    int currentFrameIndex = 1;

    @Override
    public void run() {
        // 更新动画图标的显示帧
        Bitmap frameBitmap = BitmapFactory.decodeResource(getResources(), getAnimationFrameResource(currentFrameIndex));
        remoteViews.setImageViewBitmap(R.id.animation_icon, frameBitmap);
        currentFrameIndex = getNextAnimationFrameIndex(currentFrameIndex);

        // 刷新通知
        handler.post(new Runnable() {
            @Override
            public void run() {
                NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                notificationManager.notify(notificationId, notificationBuilder.build());
            }
        });
    }
};
timer.schedule(task, 0, 100); // 每 100 毫秒更新一次帧

// 将自定义布局设置为通知的 contentView
notificationBuilder.setCustomContentView(remoteViews);
