如何以编程方式检查蓝牙是否已启用? [英] How to check if bluetooth is enabled programmatically?

问题描述

我想定期检查是否在任何 Android 设备上启用了蓝牙.我可以使用 BroadcastReceiver 捕获任何意图，或者有其他方法可以做到吗?

I would like to check if bluetooth is enabled on any Android device periodically. Is there any intents that I could catch using BroadcastReceiver to do so, or is there other ways to do it?

推荐答案

给你:

BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (mBluetoothAdapter == null) {
    // Device does not support Bluetooth
} else if (!mBluetoothAdapter.isEnabled()) {
    // Bluetooth is not enabled :)
} else {
    // Bluetooth is enabled 
}

使用 uses-permission

 <uses-permission android:name="android.permission.BLUETOOTH" android:required="false" />
