我有以下问题:
我有一个列表视图,我想为此列表视图的项目分隔符(分隔符)指定渐变颜色.我使用以下代码:
list = (ListView) findViewById(R.id.list);
int[] colors = { 0, 0xffffff00, 0 };
list.setDivider(new GradientDrawable(Orientation.RIGHT_LEFT, colors));
list.setDividerHeight(4);

我从以下网站查找颜色代码(0xffffff00):http://developer.android.com/reference/android/graphics/Color.html
