获取WheelView选定的值

我正在使用https://github.com/chemalarrea/Android-wheel。我使用的视图是Wheel2演示中的Time2。但是我无法获得所选项目的文本。我已经尽我的运气获取WheelView选定的值

Calendar calendar; 
ArrayList<TextView> tvlist; 

    @SuppressLint("SimpleDateFormat") 
@Override 
public View getItem(int index, View cachedView, ViewGroup parent) { 
    int day = -daysCount/2 + index; 
    Calendar newCalendar = (Calendar) calendar.clone(); 
    newCalendar.roll(Calendar.DAY_OF_YEAR, day); 

    View view = super.getItem(index, cachedView, parent); 
    TextView monthday = (TextView) view.findViewById(R.id.time2_monthday); 
    if (day == 0) { 
     DateFormat format = new SimpleDateFormat("MMM d"); 
     monthday.setText("Today"); 
     monthday.setTextColor(0xFF0000F0); 
    } else { 
     DateFormat format = new SimpleDateFormat("EEE, MMM d"); 
     monthday.setText(format.format(newCalendar.getTime())); 
     monthday.setTextColor(0xFF111111); 
     tvlist.add(monthday); 
    } 
    return view; 
} 

@Override 
public int getItemsCount() { 
    return daysCount + 1; 
} 

@Override 
public CharSequence getItemText(int index) { 
    return ""; 
} 

public String getText(int index){ 
    return tvlist.get(index).getText().toString(); 
}

在DayArrayAdapter然后在我的活动我叫：

String temp = this.dayarrayadapter.getText(this.w_date.getCurrentItem());

然而，问题是，当我tvlist添加TextView的，它是不是在正确的顺序，所以当我在索引上得到了它的基础，它为我返回了错误的值。我在这里和那里搜索了很多，但仍然没有运气。

这是我迄今所做的：

public class DayArrayAdapter extends AbstractWheelTextAdapter { 
    // Count of days to be shown 
    private final int daysCount = 40; 

    // Calendar 
    Calendar calendar; 

    ArrayList<String> daylist; 

    /** 
    * Constructor 
    */ 
    public DayArrayAdapter(Context context, Calendar calendar) { 
     super(context, R.layout.date, NO_RESOURCE); 
     this.calendar = calendar; 

     setItemTextResource(R.id.time2_monthday); 
     daylist = new ArrayList<String>(); 
    } 

    @SuppressLint("SimpleDateFormat") 
    @Override 
    public View getItem(int index, View cachedView, ViewGroup parent) { 
     int day = -daysCount/2 + index; 
     Calendar newCalendar = (Calendar) calendar.clone(); 
     newCalendar.roll(Calendar.DAY_OF_YEAR, day); 

     View view = super.getItem(index, cachedView, parent); 

     TextView monthday = (TextView) view.findViewById(R.id.time2_monthday); 
     if (day == 0) { 
      monthday.setText("Today"); 
      monthday.setTextColor(0xFF0000F0); 
     } else { 
      DateFormat format = new SimpleDateFormat("EEE, MMM d"); 
      monthday.setText(format.format(newCalendar.getTime())); 
      monthday.setTextColor(0xFF111111); 
      if(daylist.size()>0){ 
       for(int i=0; i<40; i++){ 
        daylist.add(format.format(newCalendar.getTime())); 
        for (int j = daylist.size(); j > 2; j--){ 
         if(daylist.get(daylist.size()-1).toString().equals(daylist.get(j-2).toString())){ 
          daylist.remove(daylist.size()-1); 
         } 
         else if (daylist.get(daylist.size()-1).toString().equals(daylist.get(1).toString()) 
           || daylist.get(daylist.size()-1).toString().equals(daylist.get(0).toString())){ 
          daylist.remove(daylist.size()-1); 
         } 
        } 
       } 
      } 
      else 
       daylist.add(format.format(newCalendar.getTime())); 
     } 

     return view; 
    } 

    @Override 
    public int getItemsCount() { 
     return daysCount + 1; 
    } 

    @Override 
    public CharSequence getItemText(int index) { 
     return ""; 
    } 

    public ArrayList<String> getText(){ 
     return daylist; 
    } 

}

和我daylist将返回：

所以你看，顺序错了，所以在我的活动，当我使用

ArrayList<String> tmp = this.dayarrayadapter.getText(); 
this.TextView.setText(tmp.get(this.w_date.getCurrentItem()));

则返回错误值

什么是“我”在你的getText（）方法，你是如何让您的daysCount？ –

对不起，我是索引。 daysCount是一个int变量，我将它设置为40，这样轮子将显示40天供用户选择。如果可能的话，我认为你应该首先看看GitHub上的项目，因为我不能在这里发布WheelView类和所有的代码，这可能太长了。抱歉给你带来不便。 – DucTran

在您的主要活动中试用此功能之前，请将wheelview课程与mainactivity课程一起使用，然后才能正常工作。

final WheelView country = (WheelView)v11.findViewById(R.id.country); 
country.setVisibleItems(3); 
country.setViewAdapter(new CountryAdapter(this)); 

country.addScrollingListener(new OnWheelScrollListener() 
{ 
public void onScrollingStarted(WheelView wheel) 
{ 
//scrolling = true; 
} 
public void onScrollingFinished(WheelView wheel) 
{ 
//scrolling = false 
//updateCities(city, cities, country.getCurrentItem()); 
//Toast.makeText(MainActivity.this, "wheel : "+wheel.getCurrentItem(), 120).show(); 

int wheel_item = wheel.getCurrentItem(); 

if (wheel_item == 0) { 
//Toast.makeText(MainActivity.this, "wheel_item : "+wheel_item, 30).show(); 

// do whatever you want here 
} 
else if (wheel_item == 1) { 
//Toast.makeText(MainActivity.this, "wheel_item : "+wheel_item, 30).show(); 
// do whatever you want here 
} 
else if (wheel_item == 2) { 
//Toast.makeText(MainActivity.this, "wheel_item : "+wheel_item, 30).show(); 
// do whatever you want here 
} 
else if (wheel_item == 3) 
{ 
// do whatever you want here  
} 
    }

嗨Harikrishnan，非常感谢您的回复。不过，正如我之前所说，我可以得到目前的项目顺序，但我不知道谁来得到它的文本。我在DayArrayAdapter和ArrayWheelTextAdapter中使用了Time2，它们与“城市中的适配器”活动有所不同。在NumericWheelAdapter它有getItemText（）方法，我尝试复制和修改它为我的用法，但仍然没有运气:( – DucTran

public AbstractWheel ringsize = (AbstractWheel)findViewById(R.id.ringsize);

设置在AbstractWheel适配器后。并设置addChangingListener事件

addChangingListener(ringsize, "ringsize"); 


private void addChangingListener(final AbstractWheel wheel, 
     final String label) { 
    wheel.addChangingListener(new com.theengager.spinnerwheel.OnWheelChangedListener() { 
     public void onChanged(AbstractWheel wheel, int oldValue, 
       int newValue) { 
      setData(rsizearr[newValue]); 
     } 
    }); 
}
