Java 从两个计时器获取总小时数

有人能告诉我如何从两个时间选择器中获取总小时数吗？因为两个时间选择器实际上是从同一个函数中获取的，所以可以获取总小时数

WorkDetails.java

        EditText TimeIn = (EditText) findViewById(R.id.editText6);
        EditText TimeOut = (EditText) findViewById(R.id.editText7);
        TimeIn.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus) {
                    TimePick time = new TimePick(v);
                    FragmentTransaction ft = getFragmentManager().beginTransaction();
                    time.show(ft, "TimePicker");
                }
            }
        });


        TimeOut.setOnFocusChangeListener(new View.OnFocusChangeListener(){
            @Override
            public void onFocusChange(View v,boolean hasFocus) {
                if (hasFocus) {
                    TimePick time = new TimePick(v);
                    FragmentTransaction ft = getFragmentManager().beginTransaction();
                    time.show(ft, "TimePicker");

                }
            }
        });

public class TimePick extends DialogFragment implements TimePickerDialog.OnTimeSetListener {
   EditText time;

    public TimePick(View view)
    {
       time=(EditText)view;
    }

    public Dialog onCreateDialog(Bundle savedInstanceState)
    {
        final Calendar c= Calendar.getInstance();
        int hour=c.get(Calendar.HOUR_OF_DAY);
        int minute=c.get(Calendar.MINUTE);
        return new TimePickerDialog(getActivity(),this,hour,minute, DateFormat.is24HourFormat(getActivity()));
    }

    public void onTimeSet(TimePicker view,int hourofDay, int minute)
    {

        time.setText(Integer.toString(hourofDay) + ":" + Integer.toString(minute));
    }


}

TimePick.java

        EditText TimeIn = (EditText) findViewById(R.id.editText6);
        EditText TimeOut = (EditText) findViewById(R.id.editText7);
        TimeIn.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (hasFocus) {
                    TimePick time = new TimePick(v);
                    FragmentTransaction ft = getFragmentManager().beginTransaction();
                    time.show(ft, "TimePicker");
                }
            }
        });


        TimeOut.setOnFocusChangeListener(new View.OnFocusChangeListener(){
            @Override
            public void onFocusChange(View v,boolean hasFocus) {
                if (hasFocus) {
                    TimePick time = new TimePick(v);
                    FragmentTransaction ft = getFragmentManager().beginTransaction();
                    time.show(ft, "TimePicker");

                }
            }
        });

public class TimePick extends DialogFragment implements TimePickerDialog.OnTimeSetListener {
   EditText time;

    public TimePick(View view)
    {
       time=(EditText)view;
    }

    public Dialog onCreateDialog(Bundle savedInstanceState)
    {
        final Calendar c= Calendar.getInstance();
        int hour=c.get(Calendar.HOUR_OF_DAY);
        int minute=c.get(Calendar.MINUTE);
        return new TimePickerDialog(getActivity(),this,hour,minute, DateFormat.is24HourFormat(getActivity()));
    }

    public void onTimeSet(TimePicker view,int hourofDay, int minute)
    {

        time.setText(Integer.toString(hourofDay) + ":" + Integer.toString(minute));
    }


}

您可以使用（.）点>>计算一天中的小时数，然后将其解析为浮点>>并进行更改。下面是一个工作代码片段

        float end = Float.parseFloat("21.00");
        float start = Float.parseFloat("10.00");

        System.out.println(end-start);

更改您的方法，如：

public void onTimeSet(TimePicker view,int hourofDay, int minute)
    {

        time.setText(Integer.toString(hourofDay) + "." + Integer.toString(minute));
    }

然后从

editText.gettext（）获取值

编辑：

将您的
TimeIn
editText变量设置为静态，并在如下设置超时时获取其值

    public void onTimeSet(TimePicker view,int hourofDay, int minute)
        {

            time.setText(Integer.toString(hourofDay) + "." + Integer.toString(minute));

          if(time.getId==R.id.editText7){
            if(YourActivity.TimeIn !=null){
            String timeIn = YourActivity.TimeIn.getText().toString();

            float end = Float.parseFloat(time.getText().toString);
            float start = Float.parseFloat(timeIn);

            System.out.println(end-start);
           // do what you need with your calculated hours
         }
        }
        }

使用计时器选择器Id尝试开关和机箱

     public void onTimeSet(TimePicker view,int hourofDay, int minute)
                {
                  int start,end,remains;
                  switch(view.getId()){
                       case R.id.editText6: 
                                   time.setText(Integer.toString(hourofDay) + ":" + Integer.toString(minute));
                                   start=hourofDay;
                                   break;
                       case R.id.editText7: 
                                   time.setText(Integer.toString(hourofDay) + ":" + Integer.toString(minute));
                                   end=hourofDay;
                                   break;
                                    }
                        //Use can declare remains globlally and use where you want
                         remain=end-start;

                 }

使用（.）>>将小时和分钟转换为浮点>>执行计算。。注。。时间应该是24小时制。你能解释更多吗？谢谢，但是既然结束值和开始值在同一个函数（onTimeSet）中，我怎么才能得到它们呢。。。在某个按钮上单击？我希望它是自动的..在用户选择time in和time out之后，它将显示总小时数--假设我得到time in的一个值和time out的另一个值。如何将它们传递到一个函数中？在
YourActivity
中设置
EditText TimeIn
静态，并在
onTimeSet（）中获取
TimeIn
的值，同时设置
TimeOut
。。。查看编辑。如何从editText 6和editText 7获取总小时数？在版面中使用
Timepicker
，而不是
editText
，并在活动中初始化
