Android编程之TimePickerDialog设置确定键导致OnTimeSetListener不响应问题
在调用TimePickerDialog时，如果要修改TimePickerDialog中确定键的名字，就需要调用setButton(int whichButton,CharSequence text,OnClickListener listener)方法，重新设置确定键的名字。但这样直接设置，例如下面的代码，就会造成OnTimeSetListener中onTimeSet不响应。
[java]
TimePickerDialog timePickerDialog = new TimePickerDialog(this,
new OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay,
int minute) {
System.out.println("time:" + hourOfDay + ":"
+ minute);
}
}, calendar.get(Calendar.HOUR_OF_DAY),
calendar.get(Calendar.MINUTE), false);
timePickerDialog.setTitle(R.string.title);
timePickerDialog.setButton(TimePickerDialog.BUTTON_POSITIVE,
getString(R.string.ok),
new DialogInte易做图ce.OnClickListener() {
public void onClick(DialogInte易做图ce dialog, int which) {
}
});
timePickerDialog.show();
所以，这里要改一下setButton(int whichButton, CharSequence text,OnClickListener listener)中，最后传入的参数，由OnClickListener listener改为TimePickerDialog对象本事，这样就可以响应OnTimeSetListener中onTimeSet的方法。代码如下：
[java]
TimePickerDialog timePickerDialog = new TimePickerDialog(this,
new OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay,
int minute) {
System.out.println("time:" + hourOfDay + ":"
+ minute);
}
}, calendar.get(Calendar.HOUR_OF_DAY),
calendar.get(Calendar.MINUTE), false);
timePickerDialog.setTitle(R.string.title);
timePickerDialog.setButton(TimePickerDialog.BUTTON_POSITIVE,
getString(R.string.ok), timePickerDialog);
timePickerDialog.show();
注意：setButton最后一个参数，不是OnClickListener对
