Android如何查看设备是否有红外线？

Question

我如何实用地知道设备在 android 中是否有红外线硬件？

我想在此基础上做一些事情。我尝试使用类似下面的东西，但没有运气。

this.getPackageManager().hasSystemFeature( .. various constants ..)

Answer 1

Use ConsumerIrManager.hasIrEmitter()

Answer 2

尝试以下代码

科特林：

val irManager: ConsumerIrManager = getSystemService(CONSUMER_IR_SERVICE) as ConsumerIrManager

        // Check whether IrEmitter is available on the device.
        if (irManager.hasIrEmitter()) {
            Log.i("IR_Testing", "found IR Emitter")       
        }else{
            Log.i("IR_Testing", "Cannot found IR Emitter on the device")
        }

Java:

private ConsumerIrManager irManager ;
irManager = (ConsumerIrManager) getSystemService(CONSUMER_IR_SERVICE);
 if (irManager.hasIrEmitter()) {
           Log.i("IR_Testing", "found IR Emitter");
        } else {
             Log.i("IR_Testing", "Cannot found IR Emitter on the device");
        }
