Hi,
As you can see in above image, I created a custom view as as item of my calendar. In code i have repeat it for example 50 times to create calendar.

服务器给我发送一个旗帜, 显示其中哪个应该选中( 在此情况下, 选择了 09 Jun ) 。

我的问题是当服务器发送一个不在屏幕上的一天( 例如 25 Jun) 时, 日期会被选中( 25 Jun 更改的背景), 但是在屏幕上我可以看到图像( 但现在 9 Jun 的背景已变换为白色 ) 。

我要找的就是在屏幕中间显示 6月25日的项目。我不知道它是如何可能的。

请提出任何建议。 Mu 习惯观点(widget)的代码是这样的:

public class Calendar_Item extends RelativeLayout {

    private LayoutInflater mInflater;
    private RelativeLayout rlContainer;
    private TextView tvMonth;
    private TextView tvDay;
    private ImageView imDot;

    public Calendar_Item(Context context) {
        super(context);
        init(context);
    }

    public Calendar_Item(Context context, AttributeSet attrs) {
        super(context, attrs);
        init(context);
    }

    public Calendar_Item(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init(context);
    }


    private void init(Context context) {
        mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        RelativeLayout calendarView = (RelativeLayout) mInflater.inflate(R.layout.calendar_item, null);
        addView(calendarView);

        rlContainer = (RelativeLayout)  calendarView.findViewById(R.id.cal_rlContainer);
        tvMonth     = (TextView)        calendarView.findViewById(R.id.cal_month);
        tvDay       = (TextView)        calendarView.findViewById(R.id.cal_date);
        imDot       = (ImageView)       calendarView.findViewById(R.id.cal_dot);
    }



    public void setMonth(String month) {
        tvMonth.setText(month);
    }

    public void setMonth(int resId) {
        tvMonth.setText(resId);
    }

    public CharSequence getMonth() {
        return tvMonth.getText();
    }

    public void setDay(String day) {
        tvDay.setText(day);
    }

    public void setDay(int resId) {
        tvDay.setText(resId);
    }

    public CharSequence getDay() {
        return tvDay.getText();
    }

    public void showDot() {
        imDot.setVisibility(View.VISIBLE);
    }

    public void hideDot() {
        imDot.setVisibility(View.INVISIBLE);
    }

    public void setTextColor(int color) {
        tvDay.setTextColor(color);
    }

    public void setBackgroundResource(int resid) {
        rlContainer.setBackgroundResource(resid);
    }

    public void setBackgroundDrawable(Drawable d) {
        rlContainer.setBackgroundDrawable(d);
    }

    public void setBackgroundColor(int color) {
        rlContainer.setBackgroundColor(color);
    }
}

XML 代码布局 :

    <?xml version="1.0" encoding="utf-8"?>

<HorizontalScrollView 
   xmlns:android            = "http://schemas.android.com/apk/res/android"
   android:layout_width     = "fill_parent" 
   android:layout_height    = "wrap_content"
   android:layout_below     = "@id/header"
   android:fadingEdgeLength = "30dip"
   android:fadingEdge       = "horizontal"
   android:scrollbars       = "none" >

   <LinearLayout 
        android:id              = "@+id/llCalendarItems"
        android:layout_width    = "wrap_content" 
        android:layout_height   = "wrap_content"
        android:orientation     = "horizontal" >

    </LinearLayout>
</HorizontalScrollView>

所有日历项目都位于LinearLayout内。
