【问题描述】：

如何在不显示timePicker 对话框的情况下获取选定的时间值？

下图是我的报警设计布局。单击按钮时，我希望它显示所选值而不是弹出 timePicker 对话框。

 alarm.setOnClickListener(new View.OnClickListener() 
            @Override
            public void onClick(View v) 

                 showDialog(TIME_DIALOG_ID);
            
        );
    

    @Override
    protected Dialog onCreateDialog(int id) 
        switch (id) 
            case TIME_DIALOG_ID:

                // set time picker as current time
                return new TimePickerDialog(this, timePickerListener, hour, minute,
                        false);
        
        return null;
    

    private TimePickerDialog.OnTimeSetListener timePickerListener = new TimePickerDialog.OnTimeSetListener() 

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minutes) 
            // TODO Auto-generated method stub
            hour   = hourOfDay;
            minute = minutes;
            updateTime(hour,minute);
        
    ;

    // Used to convert 24hr format to 12hr format with AM/PM values
    private void updateTime(int hours, int mins) 

        String timeSet = "";
        if (hours > 12) 
            hours -= 12;
            timeSet = "PM";
         else if (hours == 0) 
            hours += 12;
            timeSet = "AM";
         else if (hours == 12)
            timeSet = "PM";
        else
            timeSet = "AM";


        String minutes = "";
        if (mins < 10)
            minutes = "0" + mins;
        else
            minutes = String.valueOf(mins);

        // Append in a StringBuilder
        String aTime = new StringBuilder().append(hours).append(':')
                .append(minutes).append(" ").append(timeSet).toString();

       Toast.makeText(getApplicationContext(),aTime,Toast.LENGTH_LONG).show();
    

我应该在哪里更改按钮单击？谢谢。

【参考方案1】：

内部按钮点击，删除

showDialog(TIME_DIALOG_ID); 并替换为

int hour = alarmTimePicker.getCurrentHour();
int min = alarmTimePicker.getCurrentMinute();
updateTime(hour,min); 

alarmTimePicker 遵循 timePicker 名称，用于初始化 timePicker。

例如：

TimePicker alarmTimePicker = (TimePicker) findViewById(R.id.timePicker);

删除下面的代码，因为不需要对话框。

@Override
    protected Dialog onCreateDialog(int id) 
        switch (id) 
            case TIME_DIALOG_ID:

                // set time picker as current time
                return new TimePickerDialog(this, timePickerListener, hour, minute,
                        false);
        
        return null;
    

    private TimePickerDialog.OnTimeSetListener timePickerListener = new TimePickerDialog.OnTimeSetListener() 

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minutes) 
            // TODO Auto-generated method stub
            hour   = hourOfDay;
            minute = minutes;
            updateTime(hour,minute);
        
    ;
