TimePicker仅分钟和setmaximum分钟，如果用户输入的时间与键盘 [英] TimePicker only show minutes and setmaximum minutes if the user enter a time with the keyboard
本文介绍了TimePicker仅分钟和setmaximum分钟，如果用户输入的时间与键盘的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这是我的timepicker期待的时刻。 我希望它只是显示分钟，分钟只有最多30个。 它工作正常，但是当u进入时间用键盘它设置的时间为0，但我想它去到最大。 如果用户输入50，就应该到30，我怎么能做到这一点？ 我怎么能隐藏timepicker的小时的原因，而是这里没有必要的。

};

INT nextHour = 0;
如果（分钟→30）{
的System.out.println（分+ 30）;
nextMinute = 30;
//设定分钟
timePicker.setCurrentMinute（nextMinute）;
}
其他 {
的System.out.println（分0）;
nextMinute = 0;
}
如果（hourOfDay！= 0）{
的System.out.println（小时大于0）;
nextHour = 24;
}
//删除ontimechangedlistener至prevent计算器/无限循环
timePicker.setOnTimeChangedListener（NullTimeChangedListener）;
//设定分钟
timePicker.setCurrentMinute（timePicker.getCurrentMinute（）+ nextMinute）;
//设置小时
timePicker.setCurrentHour（nextHour）;
//挂钩ontimechangedlistener再次
timePicker.setOnTimeChangedListener（StartTimeChangedListener）;
}
解决方案
这就是我做的最大，最小值以及5分钟步骤的一部分，也有对计算器的样本，但他们的方法你无法同时使用了和向下按钮，用我的方法，它的工作原理：
公共类的PowerNapTM延伸活动{
/ **第一次创建活动时调用。 * /
@覆盖
保护无效的onCreate（包savedInstanceState）{
的System.out.println（的PowerNapTM）;
super.onCreate（savedInstanceState）;
的setContentView（R.layout.powernap）;
TimePicker PN =（TimePicker）findViewById（R.id.tp_powernap）;
pn.setCurrentMinute（5）;
的System.out.println（timepicker erstellt）;
pn.setDescendantFocusability（TimePicker.FOCUS_BLOCK_DESCENDANTS）;
的System.out.println（Tastatur geblockt）;
pn.setOnTimeChangedListener（StartTimeChangedListener）;
的System.out.println（starttimechangedlistener）;
pn.setIs24HourView（真正的）;
}
私人TimePicker.OnTimeChangedListener StartTimeChangedListener =
新TimePicker.OnTimeChangedListener（）{
公共无效onTimeChanged（TimePicker观点，诠释hourOfDay，INT分钟）{
updateDisplay（查看，hourOfDay，分钟）;
}
};
私人TimePicker.OnTimeChangedListener NullTimeChangedListener =
新TimePicker.OnTimeChangedListener（）{
公共无效onTimeChanged（TimePicker观点，诠释hourOfDay，INT分钟）{
}
};
私人无效updateDisplay（TimePicker timePicker，诠释hourOfDay，INT分钟）{
//做下一次计算
INT nextMinute = 0;
INT nextHour = 0;
如果（分钟＆GT; = 30＆安培;＆安培;分钟＆LT; = 59）{
的System.out.println（分+ 30）;
nextMinute = 30;
}
否则，如果（分钟== 26）{
的System.out.println（分AUF 30）;
nextMinute = 30;
}
否则，如果（分钟== 25 ||分钟== 21 ||分钟== 29）{
的System.out.println（分AUF 25）;
nextMinute = 25;
}
否则，如果（分钟== 20 ||分钟== 16 ||分钟== 24）{
的System.out.println（分AUF 20）;
nextMinute = 20;
}
否则，如果（分钟== 15 ||分钟== 11 ||分钟== 19）{
的System.out.println（分AUF 15）;
nextMinute = 15;
}
否则，如果（分钟== 10 ||分钟== 6 ||分钟== 14）{
的System.out.println（分AUF 10）;
nextMinute = 10;
}
否则，如果（分钟== 5 ||分钟== 1 ||分钟== 9 ||分钟小于5）{
的System.out.println（分AUF 5）;
nextMinute = 5;
}
如果（hourOfDay！= 0）{
的System.out.println（小时大于0）;
nextHour = 24;
}
//删除ontimechangedlistener至prevent计算器/无限循环
timePicker.setOnTimeChangedListener（NullTimeChangedListener）;
//设定分钟
timePicker.setCurrentMinute（nextMinute）;
//设置小时
timePicker.setCurrentHour（nextHour）;
//挂钩ontimechangedlistener再次
timePicker.setOnTimeChangedListener（StartTimeChangedListener）;
}
This is how my timepicker looks at the moment. I want it to only display the minutes and the minutes only to maximum 30. It works fine but when u enter the time with the keyboard it sets the time to 0 but i want it to go to the maximum. so if a user enters 50 it should go to 30, how can i do this? and how can i hide the hour of the timepicker cause it's not needed here.
protected void onCreate(Bundle savedInstanceState) {
System.out.println("Powernap");
super.onCreate(savedInstanceState);
setContentView(R.layout.powernap);
TimePicker pn = (TimePicker) findViewById(R.id.tp_powernap);
pn.setOnTimeChangedListener(StartTimeChangedListener);
pn.setIs24HourView(true);
}
private TimePicker.OnTimeChangedListener StartTimeChangedListener =
new TimePicker.OnTimeChangedListener() {
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
updateDisplay(view, hourOfDay, minute);
}
};
private TimePicker.OnTimeChangedListener NullTimeChangedListener =
new TimePicker.OnTimeChangedListener() {
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
}
};
private void updateDisplay(TimePicker timePicker, int hourOfDay, int minute) {
// do calculation of next time
int nextMinute = 0;
int nextHour = 0;
if (minute > 30){
System.out.println("Minute+30");
nextMinute = 30;
// set minute
timePicker.setCurrentMinute(nextMinute);
}
else {
System.out.println("minute 0");
nextMinute = 0;
}
if (hourOfDay != 0){
System.out.println("hour>0");
nextHour = 24;
}
// remove ontimechangedlistener to prevent stackoverflow/infinite loop
timePicker.setOnTimeChangedListener(NullTimeChangedListener);
// set minute
timePicker.setCurrentMinute(timePicker.getCurrentMinute()+nextMinute);
//set hour
timePicker.setCurrentHour(nextHour);
// hook up ontimechangedlistener again
timePicker.setOnTimeChangedListener(StartTimeChangedListener);
}
解决方案
that's how i did the part with the maximum and minimum and the 5mins steps, there are samples on stackoverflow but with their methods u can't use both the up and the down button, with my method it works:
public class Powernap extends Activity {
/** Called when the activity is first created. */
@Override
protected void onCreate(Bundle savedInstanceState) {
System.out.println("Powernap");
super.onCreate(savedInstanceState);
setContentView(R.layout.powernap);
TimePicker pn = (TimePicker) findViewById(R.id.tp_powernap);
pn.setCurrentMinute(5);
System.out.println("timepicker erstellt");
pn.setDescendantFocusability(TimePicker.FOCUS_BLOCK_DESCENDANTS);
System.out.println("Tastatur geblockt");
pn.setOnTimeChangedListener(StartTimeChangedListener);
System.out.println("starttimechangedlistener");
pn.setIs24HourView(true);
}
private TimePicker.OnTimeChangedListener StartTimeChangedListener =
new TimePicker.OnTimeChangedListener() {
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
updateDisplay(view, hourOfDay, minute);
}
};
private TimePicker.OnTimeChangedListener NullTimeChangedListener =
new TimePicker.OnTimeChangedListener() {
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
}
};
private void updateDisplay(TimePicker timePicker, int hourOfDay, int minute) {
// do calculation of next time
int nextMinute = 0;
int nextHour = 0;
if (minute >= 30 && minute <= 59){
System.out.println("Minute+30");
nextMinute = 30;
}
else if(minute == 26){
System.out.println("Minute auf 30");
nextMinute = 30;
}
else if(minute == 25 || minute == 21 || minute == 29){
System.out.println("Minute auf 25");
nextMinute = 25;
}
else if(minute == 20 || minute == 16 || minute == 24){
System.out.println("Minute auf 20");
nextMinute = 20;
}
else if(minute == 15 || minute == 11 || minute == 19){
System.out.println("Minute auf 15");
nextMinute = 15;
}
else if(minute == 10 || minute == 6 || minute == 14){
System.out.println("Minute auf 10");
nextMinute = 10;
}
else if(minute == 5 || minute == 1 || minute == 9 || minute < 5){
System.out.println("Minute auf 5");
nextMinute = 5;
}
if (hourOfDay != 0){
System.out.println("hour>0");
nextHour = 24;
}
// remove ontimechangedlistener to prevent stackoverflow/infinite loop
timePicker.setOnTimeChangedListener(NullTimeChangedListener);
// set minute
timePicker.setCurrentMinute(nextMinute);
//set hour
timePicker.setCurrentHour(nextHour);
// hook up ontimechangedlistener again
timePicker.setOnTimeChangedListener(StartTimeChangedListener);
}
