同样的代码在eclipse下能执行LeScanCallback的onLeScan方法 而到了android studio 中就不执行了 权限都加了,是不是android studio中还有配置别的东西?
public class Blues {
Context con;
Blues.M_LeScanCallback_interface callback_interface;
private BluetoothAdapter mBluetoothAdapter;
private LeScanCallback mLeScanCallback = new LeScanCallback() {
public void onLeScan(BluetoothDevice device, int rssi, byte[] scanRecord) {
Blues.this.callback_interface.get_address(device.getAddress());
}
};
public Blues(Context con, Blues.M_LeScanCallback_interface callback_interface) {
//在eclipse中 就加执行到这里 在android studio中就不会
BluetoothManager bluetoothManager = (BluetoothManager)con.getSystemService("bluetooth");
this.mBluetoothAdapter = bluetoothManager.getAdapter();
this.con = con;
this.callback_interface = callback_interface;
}
public void scanLeDevice(boolean enable) {
if(enable) {
this.mBluetoothAdapter.startLeScan(this.mLeScanCallback);
} else {
this.mBluetoothAdapter.stopLeScan(this.mLeScanCallback);
}
}
public interface M_LeScanCallback_interface {
void get_address(String var1);
}
}
//下面是activity中的调用
public class MainActivity extends Activity implements Blues.M_LeScanCallback_interface {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
protected void onResume() {
super.onResume();
Blues blues = new Blues(this, this);
blues.scanLeDevice(true);
}
@Override
public void get_address(String str) {
Toast.makeText(getApplicationContext(), "" + str, Toast.LENGTH_SHORT).show();
}
}
