可以使用单个Drawable Xml文件显示不同的颜色边框吗？

我在单个布局中有多个相对布局，我想为指定的相对布局分配不同的颜色边界。我能够在RelativeLayout中为One提供特定颜色的边框。我可以在一个xml可绘制文件中指定不同的颜色边框吗？可以使用单个Drawable Xml文件显示不同的颜色边框吗？

这可以用不同的绘制对象的xml文件来实现，但是我想内同一绘制对象文件中的单绘制对象XML file.Is这可能实现内？

可以是显而易见的。为此使用'GradientDrawable'。 – Piyush

我会检查GradientDrawable @ Piyush.Id是无法识别的Drawable.How这可能是相关的piyush。我弄糊涂了 – Ghimire

和Java类中使用下面的代码

rl1 = (RelativeLayout) findViewById(R.id.rl_1); 
     rl2 = (RelativeLayout) findViewById(R.id.rl_2); 
     rl3 = (RelativeLayout) findViewById(R.id.rl_3); 

     ((GradientDrawable)rl1.getBackground()).setStroke(10,Color.parseColor("#FFEEDC")); 


     ((GradientDrawable)rl2.getBackground()).setStroke(10,Color.parseColor("#C7DCEF")); 


     ((GradientDrawable)rl3.getBackground()).setStroke(10,Color.parseColor("#D7EDD6"));

如果我的答案可以帮助你请upvote我 –

我收到空指针exception.editted请检查 – Ghimire

我已经检查过它，我已经分享了我的完整代码和输出。请使用我分享的整个代码。 –

是的，您可以通过使用下面的代码来实现此目的。

<RelativeLayout 
    android:id="@+id/rl" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:background="@drawable/your drawble" /> 

    ((GradientDrawable)rl.getBackground()).setColor(Color.parseColor("#F8981D"));

问题没有解决。 – Ghimire

我得到空指针异常 – Ghimire

可以使用单个Drawable Xml文件显示不同的颜色边框吗？
