Question

我使用闹钟服务来启动通知。我想根据pendingIntent调用它的通知中有不同的图像。我尝试通过意图传递此ID，但应用程序崩溃

        Intent myIntent = new Intent(AndroidAlarmService.this, MyAlarmService.class);
        //pass something to intent
        myIntent.putExtra("param", 999);

        pendingIntent = PendingIntent.getService(AndroidAlarmService.this, 0, myIntent, 0);

在服务类中，我通过

捕获它

int test =  intent.getExtras().getInt("param", -1);
Toast.makeText(this, test, Toast.LENGTH_SHORT).show();//the app crashes here!

然而，应用程序在标记的行中崩溃。

我应该如何将图片ID传递给服务，以便我可以使用此ID在规范中设置图片？

修改

这是发生错误时的logcat

Toast.makeText(this, test, Toast.LENGTH_SHORT).show();//the app crashes here!

表示您正在发送一个int作为消息。这反过来意味着您要告诉Android查找资源ID为999的String。 将其更改为：

Toast.makeText(this, String.valueOf(test), Toast.LENGTH_SHORT).show();//the app won't crash here
