Android通知栏显示网络图片并点击跳转传值

Android通知栏显示网络图片并点击跳转传值

有时通知栏需要显示网络图片，新闻类或者音乐播放。不过越高的版本越难搞。

一、思路：

用NotificationCompat的.setLargeIcon

二、效果图：

也可以看视频直观点：

三、关键代码：

class MainActivity : AppCompatActivity() {override fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)setContentView(R.layout.activity_main)val imageNetUrl = "https://gimg2.baidu.com/image_search/src=http%3A%2F%2Fi0.hdslb.com%2Fbfs%2Farticle%2F845eb3dc0fdc4ad2f7a9fc11a43a50d956125e3f.jpg&refer=http%3A%2F%2Fi0.hdslb.com&app=2002&size=f9999,10000&q=a80&n=0&g=0n&fmt=jpeg?sec=1638346070&t=e6e4d52cdbc52ea2da6102a02bd73508"var imageBitmap : Bitmap? = nullGlide.with(this).asBitmap().load(imageNetUrl).apply(RequestOptions().circleCrop().autoClone()).into(object : SimpleTarget<Bitmap>(){override fun onResourceReady(resource: Bitmap?, transition: Transition<in Bitmap>?) {imageBitmap = resource}})val manager = getSystemService(Context.NOTIFICATION_SERVICE) asNotificationManagerif (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {val channel = NotificationChannel("important", "Important",NotificationManager.IMPORTANCE_HIGH)manager.createNotificationChannel(channel)}//Glide生成bitmap需要时间，这点要注意findViewById<View>(R.id.tv_click).setOnClickListener {val intent = Intent(this,NotificationToActivity::class.java)intent.putExtra("notify_msg","通知栏包括的信息")//这里requestCode参数不能为0，否则没法传值val pi = PendingIntent.getActivity(this,((Math.random() * 1000) + 1).toInt(),intent,PendingIntent.FLAG_IMMUTABLE)val notification = NotificationCompat.Builder(this, "important").setContentTitle("This is  title").setContentText("This is content text")
