andriod6.0下webview的定位

今天試了下webview裡面的定位，找了好多資料，由於同事和我的手機基本上是andriod6.0的了，我測試了好幾次，老是顯示未授權，明明已經給它授權了，後來我才想到andriod6.0是有授權問題的，下面上代碼，先是webview下gps定位的：

public class MainActivity extends AppCompatActivity {
/**

 * See https://g.co/AppIndexing/AndroidStudio for more information.
 */

EditText mText;
private LocationManager lm;
private static final String TAG = "MainActivity";
String bestProvider;
String provider;
private WebView webView;

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    Log.e(TAG, "onRequestPermissionsResult");

    //requestpermisiion result , permission
}

@Override
protected void onDestroy() {
    super.onDestroy();
    if (lm != null) {
        lm.removeGpsStatusListener(listener);
    }
}

//位置監聽
public LocationListener locationListener = new LocationListener() {

    /**
     * 位置信息變化時觸發
     */
    @Override
    public void onLocationChanged(Location location) {
        updateView(location);
        Log.e(TAG, "時間：" + location.getTime());
        Log.e(TAG, "經度：" + location.getLongitude());
        Log.e(TAG, "緯度：" + location.getLatitude());
        Log.e(TAG, "海拔：" + location.getAltitude());
    }

    /**

    @Override

        Log.e(TAG, "onStatusChanged status=" + status);
        switch (status) {
            //GPS狀態為可見時
            case LocationProvider.AVAILABLE:
                Log.i(TAG, "當前GPS狀態為可見狀態");

gps室內定位不是很靈敏不過可以網絡定位
