android11监测两路HDMI输出信号代码实现

实现 Android 11 监测两路 HDMI 输出信号的代码如下：

private final BroadcastReceiver mHdmi1Receiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_HDMI_PLUGGED)) {
            int state = intent.getIntExtra(HdmiManager.EXTRA_HDMI_PLUG_STATE, -1);
            if (state == HdmiManager.HDMI_PLUGGED) {
                // HDMI 1 is plugged in
            } else if (state == HdmiManager.HDMI_UNPLUGGED) {
                // HDMI 1 is unplugged
            }
        }
    }
};

private final BroadcastReceiver mHdmi2Receiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_HDMI_PLUGGED)) {
            int state = intent.getIntExtra(HdmiManager.EXTRA_HDMI_PLUG_STATE, -1);
            if (state == HdmiManager.HDMI_PLUGGED) {
                // HDMI 2 is plugged in
            } else if (state == HdmiManager.HDMI_UNPLUGGED) {
                // HDMI 2 is unplugged
            }
        }
    }
};

private void registerHdmiReceivers() {
    IntentFilter hdmi1Filter = new IntentFilter(Intent.ACTION_HDMI_PLUGGED);
    IntentFilter hdmi2Filter = new IntentFilter(Intent.ACTION_HDMI_PLUGGED);

    hdmi1Filter.addAction(Intent.ACTION_HDMI_PLUGGED);
    hdmi2Filter.addAction(Intent.ACTION_HDMI_PLUGGED);

    hdmi1Filter.addCategory(Intent.CATEGORY_DEFAULT);
    hdmi2Filter.addCategory(Intent.CATEGORY_DEFAULT);

    hdmi1Filter.addDataScheme("hdmi");
    hdmi2Filter.addDataScheme("hdmi");

    registerReceiver(mHdmi1Receiver, hdmi1Filter);
    registerReceiver(mHdmi2Receiver, hdmi2Filter);
}

以上代码实现了注册两个 BroadcastReceiver 监听 HDMI 1 和 HDMI 2 的插拔事件，当 HDMI 1 或 HDMI 2 被插入或拔出时，会触发相应的回调函数，您可以在回调函数中执行相应的操作。请注意，此代码适用于 Android 11 及以上版本。
