Android通过GPS或NetWork获取当前位置信息

刚完成一个需要通过GPS获取位置信息的项目（内网项目），所以根据LocationManager获取Providers会出现依旧能判断有网络连接，debug获取providers为[passive, gps, network, local_database]。

下面贴出解决代码：

package com.src;

import java.text.SimpleDateFormat;
import java.util.List;

import android.Manifest;
import android.annotation.SuppressLint;

	String TAG = getClass().getSimpleName();

	private static final int NETWORK_NONE = -1;// 没有连接网络

	private static final int NETWORK_MOBILE = 0;// 移动网络

	private static final int NETWORK_WIFI = 1;// 无线网络

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		lon = (TextView) findViewById(R.id.lon);

	}

	@Override

		super.onDestroy();

		removeLocationUpdatesListener();
	}

	// 方法一
	/*private void getLocation() {

注意事项：

1. GPS获取位置信息需要在开阔地方才有GPS信号。

2.开启相对应的权限。
