安卓获取手机经纬度

建立my application

*获取LocationManager实例，通过getSystemService方法，传入Context.LOCATION_SERVICE参数。
*获取可用的位置提供器，有GPS_PROVIDER、NETWORK_PROVIDER、PASSIVE_PROVIDER三种，前两种比较常用。
*将获取到的位置提供器传入LocationManager的方法getLastKnownLocation，即可获取Location信息。
如果移动设备地理位置不断发生变化，则实时更新需要进行如下步骤：
*调用LocationManager的requestLocationUpdates方法，第一个参数是位置提供器，第二个参数是监听位置变化的时间间隔（毫秒），第三个参数是监听位置变化的距离间隔（米），第四个参数是LocationListener监听器
*当位置发生变化后，就会调用监听器的onLocationChanged方法。
*为了省电，节约资源，当程序关闭后，调用LocationManager的removeUpdates方法移除监听器。

具体操作步骤如下

打开android studio,选择[close],

在AndroidManfest.xml中写下如下权限，注意在application上面。

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

3.在res下的layout里的activity_main.xml里写上如下代码

<TextView
    android:id="@+id/positionView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    />

MainActivity:

package com.example.myapplication;

    //获取显示地理位置信息的TextView
    postionView = (TextView) findViewById(R.id.positionView);
    //获取地理位置管理器
    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    //获取所有可用的位置提供器
    List<String> providers = locationManager.getProviders(true);
    if (providers.contains(LocationManager.GPS_PROVIDER)) {
        //如果是GPS
        locationProvider = LocationManager.GPS_PROVIDER;
    } else if (providers.contains(LocationManager.NETWORK_PROVIDER)) {
