MainActivity代码
static final String TAG = "MainActivity"; private TextView locationTV; private LocationManager locationManager; private String provider; ArrayListdataList = new ArrayList (); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // initView(); locationTV = (TextView) findViewById(R.id.locaiton_tv); locationManager = (LocationManager) getSystemService(this.LOCATION_SERVICE); // 获取所有可用的位置提供器 List providerList = locationManager.getProviders(true); if (providerList.contains(LocationManager.GPS_PROVIDER)) { provider = LocationManager.GPS_PROVIDER; } else if (providerList.contains(LocationManager.NETWORK_PROVIDER)) { provider = LocationManager.NETWORK_PROVIDER; } else { // 当没有可用的位置提供器时,弹出Toast提示用户 Toast.makeText(this, "No location provider to use", Toast.LENGTH_SHORT).show(); return; } Location location = locationManager.getLastKnownLocation(provider); if (location != null) { // 显示当前设备的位置信息 showLocation(location); } if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { // TODO: Consider calling // ActivityCompat#requestPermissions // here to request the missing permissions, and then overriding // public void onRequestPermissionsResult(int requestCode, String[] permissions, // int[] grantResults) // to handle the case where the user grants the permission. See the documentation // for ActivityCompat#requestPermissions for more details. return; } locationManager.requestLocationUpdates(provider, 5000, 1, locationListener); } private void showLocation(Location location) { String currentPosition = "latitude is " + location.getLatitude() + "\n"+ "longitude is " + location.getLongitude(); locationTV.setText(currentPosition); } @Override protected void onDestroy() { super.onDestroy(); if (locationManager != null) { if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { // TODO: Consider calling // ActivityCompat#requestPermissions // here to request the missing permissions, and then overriding // public void onRequestPermissionsResult(int requestCode, String[] permissions, // int[] grantResults) // to handle the case where the user grants the permission. See the documentation // for ActivityCompat#requestPermissions for more details. return; } // 关闭程序时将监听器移除 locationManager.removeUpdates(locationListener); } } LocationListener locationListener = new LocationListener() { @Override public void onLocationChanged(Location location) { Toast.makeText(MainActivity.this,"onLocationChanged",Toast.LENGTH_SHORT).show(); } @Override public void onStatusChanged(String s, int i, Bundle bundle) { Toast.makeText(MainActivity.this,"onStatusChanged",Toast.LENGTH_SHORT).show(); } @Override public void onProviderEnabled(String s) { Toast.makeText(MainActivity.this,"onProviderEnabled",Toast.LENGTH_SHORT).show(); } @Override public void onProviderDisabled(String s) { Toast.makeText(MainActivity.this,"onProviderDisabled",Toast.LENGTH_SHORT).show(); } };
