我有一种情况需要使用GPS技术.

当人走路时,我需要找到两点之间的距离.

当该人开始行走时,他将点击“开始”按钮,当他停止时,他点击停止按钮

在此之后它应该告诉他

1.时间
2.在Kms旅行.
3.从哪里到哪里(地名)例如：a到b

我需要谷歌地图吗？

我在这里看到了link的代码来获取当前位置,它给出了纬度经度.

请帮忙解决这个问题

这是我正在使用的代码

private EditText editTextShowLocation;
    private Button buttonGetLocation;
    private ProgressBar progress;

    private LocationManager locManager;
    private LocationListener locListener = new MyLocationListener();

    private boolean gps_enabled = false;
    private boolean network_enabled = false;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        editTextShowLocation = (EditText) findViewById(R.id.editTextShowLocation);

        progress = (ProgressBar) findViewById(R.id.progressBar1);
        progress.setVisibility(View.GONE);

        buttonGetLocation = (Button) findViewById(R.id.buttonGetLocation);
        buttonGetLocation.setOnClickListener(this);

        locManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
    }

    @Override
    public void onClick(View v) {
        progress.setVisibility(View.VISIBLE);
        // exceptions will be thrown if provider is not permitted.
        try {
            gps_enabled = locManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
        } catch (Exception ex) {
        }
        try {
            network_enabled = locManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
        } catch (Exception ex) {
        }

        // don't start listeners if no provider is enabled
        if (!gps_enabled && !network_enabled) {
            AlertDialog.Builder builder = new Builder(this);
            builder.setTitle("Attention!");
            builder.setMessage("Sorry, location is not determined. Please enable location providers");
            builder.setPositiveButton("OK", this);
            builder.setNeutralButton("Cancel", this);
            builder.create().show();
            progress.setVisibility(View.GONE);
        }

        if (gps_enabled) {
            locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locListener);
        }
        if (network_enabled) {
            locManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locListener);
        }
    }

    class MyLocationListener implements LocationListener {
        @Override
        public void onLocationChanged(Location location) {
            if (location != null) {
                // This needs to stop getting the location data and save the battery power.
                locManager.removeUpdates(locListener); 

                String londitude = "Londitude: " + location.getLongitude();
                String latitude = "Latitude: " + location.getLatitude();
                String altitiude = "Altitiude: " + location.getAltitude();
                String accuracy = "Accuracy: " + location.getAccuracy();
                String time = "Time: " + location.getTime();

                editTextShowLocation.setText(londitude + "\n" + latitude + "\n" + altitiude + "\n" + accuracy + "\n" + time);
                progress.setVisibility(View.GONE);
            } 
        }

        @Override
        public void onProviderDisabled(String provider) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onProviderEnabled(String provider) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {
            // TODO Auto-generated method stub

        }
    }

    @Override
    public void onClick(DialogInterface dialog, int which) {
        if(which == DialogInterface.BUTTON_NEUTRAL){
            editTextShowLocation.setText("Sorry, location is not determined. To fix this please enable location providers");
        }else if (which == DialogInterface.BUTTON_POSITIVE) {
            startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
        }
    }

它显示我从仿真器控件进入的Logitude Latitude.

在这里我手动输入经度和纬度的细节
通过转到window-> showview-> other->模拟器控件进行模拟器中的测试
但我需要的是我将有两个edittext,我输入地名(A)和(B)

它应该给我的距离

请帮忙

解决方法:

尝试使用Google Distance Matrix Api
