android 通过wifi 获取经纬度和获取渠道号/屏幕宽高

1.通过wifi获取经纬度。

/**
* 通过wifi获取经纬度
*
* @return 经度，纬度
*/
private String getLocationInfo() {

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

Location location = locationManager

.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

return location.getLatitude() + "," + location.getLongitude();

}

别忘了在配置文件当中加入权限

2 判断是否联网

/**
* 判断是否有网络
*
* @return ture 为有网false为无网;
*/
private boolean isNetwork() {
  ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
  boolean bool = false;
  NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
  if (networkInfo == null || !networkInfo.isAvailable()) {
   // 当前有可用网络
   bool = false;
  } else {
   bool = true;
   // 当前无可用网络
  }
  return bool;

}

3 获取产品的渠道号

/**
* 获取产品渠道号
* @return String渠道号
*/
private String getQuDao() {

  ApplicationInfo info;
  String qudao = "";
  try {
   info = this.getPackageManager().getApplicationInfo(
     this.getPackageName(), PackageManager.GET_META_DATA);
   qudao = info.metaData.getString("PACKNAME");
  } catch (Exception e1) {
   // TODO Auto-generated catch block
   e1.printStackTrace();
  }
  return qudao;
}

需要现在配置文件中定义一个

android:name="PACKNAME"
android:value="{@market@}" />

4：android获取屏幕的高度和宽度用到WindowManager这个类，两种方法： 1 、WindowManager wm = (WindowManager) getContext() .getSystemService(Context.WINDOW_SERVICE); int width = wm.getDefaultDisplay().getWidth(); int height = wm.getDefaultDisplay().getHeight(); 2 、WindowManager wm = this .getWindowManager(); int width = wm.getDefaultDisplay().getWidth(); int height = wm.getDefaultDisplay().getHeight();
