// Set the location listener
aMap.setLocationSource(this);
// set to true to show the location layer and trigger location, false to hide the location layer and not trigger location, default is false
aMap.setMyLocationEnabled(true);
// Set the location type to location mode, there are several types of location, follow or map rotation according to orientation
aMap.setMyLocationType(AMap.LOCATION_TYPE_LOCATE);

// Set the location listener
aMap.setLocationSource(this);
// set to true to show the location layer and trigger location, false to hide the location layer and not trigger location, default is false

// Set the location type to location mode, there are several types of location, follow or map rotation according to orientation
aMap.setMyLocationType(AMap.LOCATION_TYPE_LOCATE);

Step 2, initialize the positioning

aMap.setLocationSource(this) contains two callbacks, activate(OnLocationChangedListener) and deactivate().

In activate(), set the location initialization and start the location, and in deactivate(), write the calls related to stopping the location.
Java

OnLocationChangedListener mListener;
AMapLocationClient mlocationClient;
AMapLocationClientOption mLocationOption;
/**
 * Activate the location
 */
@Override
public void activate(OnLocationChangedListener listener) {
    mListener = listener;
    if (mlocationClient == null) {
        //initialize the location
        mlocationClient = new AMapLocationClient(this);
        //initialize location parameters
        mLocationOption = new AMapLocationClientOption();
        //Set the location callback listener
        mlocationClient.setLocationListener(this);
        //set to high accuracy positioning mode
        mLocationOption.setLocationMode(AMapLocationMode.Hight_Accuracy);
        //Set the positioning parameters
        mlocationClient.setLocationOption(mLocationOption);
        // This method will initiate a location request every fixed time, in order to reduce power consumption or network traffic consumption.
        // Be careful to set the appropriate location interval (minimum interval supported is 2000ms), and call the stopLocation() method at the appropriate time to cancel the location request
        // call the onDestroy() method at the appropriate lifecycle after the location is finished
        // In the case of a single location, there is no need to call the stopLocation() method to remove the request whether the location is successful or not, the location sdk will remove it internally
        mlocationClient.startLocation();// start location
    }
}
/**
 * stopLocation
 */
@Override
public void deactivate() {
    mListener = null;
    if (mlocationClient ! = null) {
        mlocationClient.stopLocation();
        mlocationClient.onDestroy();
    }
    mlocationClient = null;
}

@Override

    if (mListener ! = null&&amapLocation ! = null) {
        if (amapLocation ! = null
                &&amapLocation.getErrorCode() == 0) {
            mListener.onLocationChanged(amapLocation);// show system small blue dot
        } else {
