您好我正在开发一个项目,要求用户启用蓝牙,一旦用户回答是,它会运行另一种连接外部设备的方法。但是,当蓝牙已经启用时,代码可以正常工作,但是当必须要求用户启用蓝牙时,它不起作用。

这是我的代码:

检查蓝牙状态

void findBTdevice() throws IOException {


    if(mBluetoothAdapter == null)
    {
        bluetoothStatus = "No bluetooth adapter available";
    }


    if (mBluetoothAdapter.isEnabled()) {

    pairBTdevices();

    } else {
        Intent enableBluetooth = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
        startActivityForResult(enableBluetooth, 0);

    }
}

关于活动结果

protected void onActivityResult(int requestCode, int resultCode, Intent Intent) {

    if (requestCode == 0) {
        if (resultCode == 0) {
            bluetoothStatus = "Bluetooth Required";

        } else {
            try {
                pairBTdevices();

            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

如果有帮助,这是日志

D/BluetoothUtils﹕ isSocketAllowedBySecurityPolicy start : device null
W/BluetoothAdapter﹕ getBluetoothService() called with no BluetoothManagerCallback
D/BluetoothSocket﹕ connect(), SocketState: INIT, mPfd: {ParcelFileDescriptor: FileDescriptor[63]}
