以下為時間轉換成字串 的工具類，可直接引用：
public class ParamsUtils {
public final static int INVALID = -1;
public static int getInt(String str){
int num = INVALID;
try {
num = Integer.parseInt(str);
} catch (NumberFormatException e) {
}
return num;
}
public static String millsecondsToStr(int seconds){ //把時間轉換成字串
seconds = seconds / 1000;
String result = "";
int hour = 0, min = 0, second = 0;
hour = seconds / 3600;
min = (seconds - hour * 3600) / 60;
second = seconds - hour * 3600 - min * 60;
if (hour < 10) {
result += "0" + hour + ":";
} else {
result += hour + ":";
}
if (min < 10) {
result += "0" + min + ":";
} else {
result += min + ":";
}
if (second < 10) {
result += "0" + second;
} else {
result += second;
}
return result;

public static int dpToPx(Context context, int height){ //dp轉換成px
float density = context.getResources().getDisplayMetrics().density;
height = (int) (height * density + 0.5f);
return height;
