动态更改操作栏分隔颜色(android:bottom用于以编程方式生成的ShapeDrawable)?

作者:互联网

我正在尝试以编程方式更改操作栏底部的分隔栏的颜色.我的策略是根据this XML将操作栏背景设置为包含ShapeDrawable矩形的以编程方式生成的LayerDrawable:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Bottom Line -->
    <item>
        <shape android:shape="rectangle">
            <solid android:color="@color/action_bar_line_color" />
        </shape>
    </item>

    <!-- Color of your action bar -->
    <item android:bottom="2dip">
        <shape android:shape="rectangle">
            <solid android:color="@color/action_bar_color" />
        </shape>
    </item>
</layer-list>

但是我遇到了障碍:我无法弄清楚如何以编程方式应用android:bottom属性(如< item android:bottom =“2dip”>).显然android:bottom是item标签的一个属性,(我认为)没有程序化的等价物,我无法找到看起来合适的ShapeDrawable的任何方法/属性.

代码到目前为止:

public LayerDrawable createABBackground(String color) {
    ShapeDrawable rect = new ShapeDrawable(new RectShape());
    rect.getPaint().setColor(Color.parseColor("#000000"));
    ShapeDrawable rect2 = new ShapeDrawable(new RectShape());
    rect2.getPaint().setColor(Color.parseColor(color));
    ShapeDrawable[] layers = {rect, rect2};
    LayerDrawable background = new LayerDrawable(layers);
    return background;
}

想法?如果它对替代解决方案很重要,我正在使用ActionBarSherlock.

编辑:

按照MH的建议,setLayerInset做了我想要的.这是使用它的函数的修改版本:

public LayerDrawable createABBackground(String color) {
    ShapeDrawable rect = new ShapeDrawable(new RectShape());
    rect.getPaint().setColor(Color.parseColor(color));
    ShapeDrawable rect2 = new ShapeDrawable(new RectShape());
    rect2.getPaint().setColor(Color.parseColor("#000000"));
    ShapeDrawable[] layers = {rect, rect2};
    LayerDrawable background = new LayerDrawable(layers);
    background.setLayerInset(0, 0, 3, 0, 0);
    background.setLayerInset(1, 0, 0, 0, 3);
    return background;
}

解决方法:

按照之前的评论:

你试试setLayerInset(int index, int l, int t, int r, int b)了吗?文档说:

Specify modifiers to the bounds for the drawable[index]. left += l top
+= t; right -= r; bottom -= b;
