public class MyGrideView extends GridView {
public MyGrideView(Context context) {
super(context);
}

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

public MyGrideView(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
}

//该自定义控件只是重写了GridView的onMeasure方法，使其不会出现滚动条，ScrollView嵌套ListView也是同样的道理，不再赘述。
@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    int expandSpec = MeasureSpec.makeMeasureSpec(
            Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
    super.onMeasure(widthMeasureSpec, expandSpec);
}

/**
 * 重绘分割线
 */

@Override
protected void dispatchDraw(Canvas canvas) {
    // TODO Auto-generated method stub
    super.dispatchDraw(canvas);

    View localView1 = getChildAt(0);
    int column = getWidth() / localView1.getWidth();
    int childCount = getChildCount();
    Paint localPaint;
    localPaint = new Paint();
    localPaint.setStyle(Paint.Style.STROKE);
    localPaint.setStrokeWidth(2);
    localPaint.setColor(getContext().getResources().getColor(R.color.gray001));
    for(int i = 0;i < childCount;i++){
        View cellView = getChildAt(i);
        if((i + 1) % column == 0){
            if (i != childCount -1){
                canvas.drawLine(cellView.getLeft(), cellView.getBottom(), cellView.getRight(), cellView.getBottom(), localPaint);
            }
        }else if((i + 1) > (childCount - (childCount % column))){
            canvas.drawLine(cellView.getRight(), cellView.getTop(), cellView.getRight(), cellView.getBottom(), localPaint);
        }else{
            canvas.drawLine(cellView.getRight(), cellView.getTop(), cellView.getRight(), cellView.getBottom(), localPaint);
            if (i != childCount -2 && i != childCount -3){
                canvas.drawLine(cellView.getLeft(), cellView.getBottom(), cellView.getRight(), cellView.getBottom(), localPaint);
            }
        }
    }
    if(childCount % column != 0){
        for(int j = 0 ;j < (column-childCount % column) ; j++){
            View lastView = getChildAt(childCount - 1);
            canvas.drawLine(lastView.getRight() + lastView.getWidth() * j, lastView.getTop(), lastView.getRight() + lastView.getWidth()* j, lastView.getBottom(), localPaint);
        }
    }
}
