我将24小时格式转换为12小时格式时遇到问题.这是我的代码.
private TimePickerDialog.OnTimeSetListener mTimeSetListener =
new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view,int hourOfDay,int minute) {
// TODO Auto-generated method stub
ViewGroup vg=(ViewGroup) view.getChildAt(0);
hour = hourOfDay;
minutes = minute;
String am_pm = (hourOfDay < 12) ? "AM" : "PM";
SimpleDateFormat sdf = new SimpleDateFormat("hh:mm a",Locale.US);
String tme = hour +":"+ minutes+am_pm;
et1.setText(tme);
}
};
我从警报对话框切换到timepicker对话框,因为我不知道如何将24小时更改为12小时格式
et1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
new TimePickerDialog(MainActivity.this,mTimeSetListener,hour,minutes,false).show();
}
});
}
这证明我已经将布尔印象变为false.
解决方法
试试这个-
private TimePickerDialog.OnTimeSetListener mTimeSetListener =
new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view,int minute) {
// TODO Auto-generated method stub
hour = hourOfDay;
minutes = minute;
String timeSet = "";
if (hour > 12) {
hour -= 12;
timeSet = "PM";
} else if (hour == 0) {
hour += 12;
timeSet = "AM";
} else if (hour == 12){
timeSet = "PM";
}else{
timeSet = "AM";
}
String min = "";
if (minutes < 10)
min = "0" + minutes ;
else
min = String.valueOf(minutes);
// Append in a StringBuilder
String aTime = new StringBuilder().append(hour).append(':')
.append(min ).append(" ").append(timeSet).toString();
et1.setText(aTime);
}
};
