以下是一段安卓BLE搜索蓝牙的代码:
```
private BluetoothAdapter mBluetoothAdapter;
private BluetoothLeScanner mBluetoothLeScanner;
private ScanCallback mScanCallback;
// 初始化蓝牙适配器和扫描回调
private void initBluetooth() {
mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
mBluetoothLeScanner = mBluetoothAdapter.getBluetoothLeScanner();
mScanCallback = new ScanCallback() {
@Override
public void onScanResult(int callbackType, ScanResult result) {
// 处理扫描结果
}
@Override
public void onScanFailed(int errorCode) {
// 处理扫描失败
}
};
}
// 开始扫描蓝牙设备
private void startScan() {
if (mBluetoothLeScanner != null) {
mBluetoothLeScanner.startScan(mScanCallback);
}
}
// 停止扫描蓝牙设备
private void stopScan() {
if (mBluetoothLeScanner != null) {
mBluetoothLeScanner.stopScan(mScanCallback);
}
}
```
这段代码可以通过调用`initBluetooth()`方法初始化蓝牙适配器和扫描回调,然后调用`startScan()`方法开始扫描蓝牙设备,调用`stopScan()`方法停止扫描。在扫描回调中,可以处理扫描结果和扫描失败的情况。
