要使用Android的WiFi和蓝牙扫描来进行定位,您可以按照以下步骤进行操作:
private WifiManager wifiManager;
private BluetoothAdapter bluetoothAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// 初始化WiFi
wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(true); // 如果WiFi未启用,启用它
// 初始化蓝牙
bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (bluetoothAdapter == null || !bluetoothAdapter.isEnabled()) {
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}
}
private List wifiScanResults;
private List bluetoothDevices;
// 扫描WiFi
private void scanWifi() {
wifiManager.startScan();
wifiScanResults = wifiManager.getScanResults();
// 处理WiFi扫描结果
for (ScanResult result : wifiScanResults) {
String ssid = result.SSID;
String bssid = result.BSSID;
int level = result.level;
// 处理扫描结果
}
}
// 扫描蓝牙
private void scanBluetooth() {
BluetoothAdapter.LeScanCallback leScanCallback = new BluetoothAdapter.LeScanCallback() {
@Override
public void onLeScan(final BluetoothDevice device, int rssi, byte[] scanRecord) {
// 处理蓝牙扫描结果
bluetoothDevices.add(device);
}
};
bluetoothAdapter.startLeScan(leScanCallback);
}
// 根据WiFi扫描结果获取定位信息
private Location getLocationFromWifi() {
// 处理WiFi扫描结果
// 返回定位信息
}
// 根据蓝牙扫描结果获取定位信息
private Location getLocationFromBluetooth() {
// 处理蓝牙扫描结果
// 返回定位信息
}
请注意,WiFi和蓝牙扫描的准确性和可用性会受到设备硬件、操作系统版本和权限等因素的影响。因此,定位结果可能会有一定的误差。
