Android中使用時間選擇器TimePickerDialog時onTimeSet執行兩次的問題

在onTimeSet方法中的賦值語句會被執行兩次，后發現這個方法會被執行那個兩次

 

monthEnd = monthEnd+1;
Log.e("month==value", "month:"+monthEnd);

本來系統的月份比實際少一個月，加1就可以了，點一次執行兩次就相當於，我選的7月，而實際卻變成了9月。

onDateSet方法把month的值賦值給了成員monthMember即monthMember = month，在onTimeSet中把month+1設置給了textview，即textview.setText(month+1),這個時候就會自動加2，所以避免這種執行兩次的情況。

網上一搜，說這是android4.1和4.2存在的一個bug，點擊確定和取消按鈕時，會出發onTimeSet；在dialog的onStop（比如dialog dismiss時）中，也調用了onTimeSet方法。需要修改framework里的TimePickerDialog.java源文件

所以說復寫對話框注掉onStop就行了，

@Override
    protected void onStop() {
        // TODO Auto-generated method stub
        //super.onStop();
    
    }

 

我的解決辦法是

1：在onDateSet方法中monthMember = month+1;來完成賦值，然后再把monthMember設置給textview，onTimeSet中只是完成了textview.settext(monthMember);並沒有加1的操作，即使是onTimeSet執行兩次也無所謂，不會受到影響。

2：第二種解決辦法：

//復寫對話框注掉onStop就行了，
@Override
    protected void onStop() {
        // TODO Auto-generated method stub
        //super.onStop();
    
    }
