一：点击事件防抖工具类：

public abstract class ThrottleClickListener implements View.OnClickListener {private long clickLastTimeKey = 0;private final long thresholdMillis = 500;//milliseconds@Overridepublic void onClick(View v) {long currentTime = SystemClock.elapsedRealtime();if (Math.abs(currentTime - clickLastTimeKey) >= thresholdMillis) {//Log.i("ygn","time-"+(currentTime - clickLastTimeKey));clickLastTimeKey = currentTime;onThrottleClick(v);} else {LogUtils.w( "click fast");}}public abstract void onThrottleClick(View v);
}二：判断经纬度是否合法，是否在指定范围内的工具类public class PoiUtil {/**只校验正数 0-90.000000 0-180.000000 范围内* 经纬度校验* 经度longitude: (?:[0-9]|[1-9][0-9]|1[0-7][0-9]|180)\\.([0-9]{6})* 纬度latitude：  (?:[0-9]|[1-8][0-9]|90)\\.([0-9]{6})* @return boolean*/public static boolean checkLoLa(String longitude,String latitude){String regLo = "(((?:[0-9]|[1-9][0-9]|1[0-7][0-9])\\.([0-9]{0,6}))|((?:180)\\.([0]{0,6}))|((?:[0-9]|[1-9][0-9]|1[0-7][0-9]))|(?:180))";String regLa = "(((?:[0-9]|[1-8][0-9]|90)\\.([0-9]{0,6}))|(?:[0-9]|[1-8][0-9]|90))";longitude = longitude.trim();latitude = latitude.trim();return longitude.matches(regLo)==true?latitude.matches(regLa):false;}/**只校验正数 0-90.000000 范围内* 纬度校验* 纬度latitude：  (?:[0-9]|[1-8][0-9]|90)\\.([0-9]{6})* @return boolean*/public static boolean checkLatitude(String latitude){String regLa ="(((?:[0-9]|[1-8][0-9]|90)\\.([0-9]{0,6}))|(?:[0-9]|[1-8][0-9]|90))";latitude = latitude.trim();return latitude.matches(regLa);}/**只校验正数 0-180.000000 范围内* 经度校验* 经度longitude: (?:[0-9]|[1-9][0-9]|1[0-7][0-9]|180)\\.([0-9]{6})* @return boolean*/public static boolean checkLongitude(String longitude){String regLo = "(((?:[0-9]|[1-9][0-9]|1[0-7][0-9])\\.([0-9]{0,6}))|((?:180)\\.([0]{0,6}))|((?:[0-9]|[1-9][0-9]|1[0-7][0-9]))|(?:180))";longitude = longitude.trim();return longitude.matches(regLo);}
