我在android中制作了一个自定义日历，为此我使用了自定义网格视图，现在我想更改日历中所选日期的颜色，但是我不知道该怎么做，我的代码如下，我正在附上自定义网格项和Java代码。请提供帮助。谢谢。

Grid_item

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/calendar_cell"
    android:gravity="center"
    android:orientation="vertical"
    android:padding="2dip" >

    <TextView
        android:id="@+id/date"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#545454"
        android:textSize="16dip"
        android:textStyle="bold" >
    </TextView>

    <ImageView
        android:id="@+id/date_icon"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/dot"
        android:visibility="gone" />

</LinearLayout>

代码

gridview.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v,
                int position, long id) {

            ((CalendarAdapter) parent.getAdapter()).setSelected(v);
            selectedGridDate = CalendarAdapter.dayString.get(position);
            String[] separatedTime = selectedGridDate.split("-");
            String gridvalueString = separatedTime[2].replaceFirst("^0*",
                    "");// taking last part of date. ie; 2 from 2012-12-02.
            int gridvalue = Integer.parseInt(gridvalueString);
            // navigate to next or previous month on clicking offdays.
            if ((gridvalue > 10) && (position < 8)) {
                setPreviousMonth();
                refreshCalendar();
            } else if ((gridvalue < 7) && (position > 28)) {
                setNextMonth();
                refreshCalendar();
            }
            ((CalendarAdapter) parent.getAdapter()).setSelected(v);

            showToast(selectedGridDate);

        }
    });

private TextView txtDate;
....
gridview.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View v,
            int position, long id) {
            //add your code here
            if(txtDate!=null)
            {
              txtDate.setTextColor(Color.parseColor("#000000")); // the color you want for unselected date
            }
            txtDate = (TextView) v.findViewById(R.id.date);
            txtDate.setTextColor(Color.parseColor("#E5AC56")); // the color you want for selected date
            .....
            .....                   
        }
    });
