Android:以编程方式 ImageButton 的非按下状态颜色

Question

目前ImageButton设置了android:background="@drawable/mem_btn",

mem_btn.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_pressed="true" >         
        <shape xmlns:android="http://schemas.android.com/apk/res/android"> 
            <stroke android:width="0dp" android:color="@color/black" />
            <solid android:color="@color/pressed"/>
            <padding android:left="5dp" android:top="5dp" 
                android:right="5dp" android:bottom="5dp" /> 
            <corners android:radius="14dp" /> 
        </shape>    
    </item>

    <item>
        <shape xmlns:android="http://schemas.android.com/apk/res/android"> 
            <stroke android:width="0dp" android:color="@color/black" />
            <solid android:color="#3366CC"/>
            <padding android:left="5dp" android:top="5dp" 
                android:right="5dp" android:bottom="2dp" /> 
            <corners android:radius="14dp" /> 
        </shape>
    </item>

</selector>

以上内容完美无缺。

问题:

我想让用户更改背景颜色:即根据用户选择的其他颜色，但使用 pressed_color 时，半径保持不变。

在这种情况下，如何以编程方式设置 xml 中的信息，使非按下状态的颜色成为一个变量？

谢谢!

感谢 Ranjit Pati 的引用，让我可以在正确的轨道上进一步研究并找到 StateListDrawable，并且以下工作完美:

public void set_buttons(int t, int color_idd) 
{
    ShapeDrawable activeDrawable = new ShapeDrawable();
    ShapeDrawable inactiveDrawable = new ShapeDrawable();

    // The corners are ordered top-left, top-right, bottom-right, bottom-left. // For each corner, the array contains 2 values, [X_radius, Y_radius]

    float[] radii = new float[8];
    for (int i = 0; i <= 7; i++) 
    {
        radii[i] =  (int) getResources().getDimension(R.dimen.footer_corners);  
    }
    inactiveDrawable.setShape(new RoundRectShape(radii, null, null));
    inactiveDrawable.getPaint().setColor(color_idd);

    activeDrawable.setShape(new RoundRectShape(radii, null, null));
    activeDrawable.getPaint().setColor( (Color.parseColor ("#008B00")));

    StateListDrawable states = new StateListDrawable();
    states.addState(new int[] {-android.R.attr.state_enabled}, inactiveDrawable);
    states.addState(new int[] {android.R.attr.state_pressed}, activeDrawable);
    btns[t].setBackground(states);
}
