LinearLayout使用不带XML的Java代码动态设置边框颜色

本文介绍了LinearLayout使用不带XML的Java代码动态设置边框颜色的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我已经对该问题进行了一些研究，但是我还没有发现类似的东西.

I have done some research on that issue , but I have not found anything similar just yet.

首先，我使用ShapeDrawable制作Linear Layout的边框，然后尝试在LinearLayout上设置背景颜色，但未设置颜色，然后注释了ShapeDrawable的两行，然后在设置Linear Layout的背景颜色后出现了问题边框颜色.

First I make a border of Linear Layout using ShapeDrawable then I have try to set background color on LinearLayout but color is not set then I have comment two line of ShapeDrawable then after I have set the background color of Linear Layout but problem occur in border color.

这是我通过背景色和边框色的JSON获得的价值.

That's value I have got through JSON of background color and border color.

我想通过Java代码动态设置该值.

I want to set that value dynamically Background color and border color of Linear Layout through java code.

请引导我.

谢谢

LinearLayout linearToAdd = new LinearLayout(getActivity()); linearToAdd.setOrientation(VERTICAL); float d = getActivity().getResources().getDisplayMetrics().density; linearToAdd.setBackgroundColor(Color.parseColor((String)(mPod.getBackground()))); switch(parentType){ case LINEAR_LAYOUT: LinearLayout.LayoutParams linearParams = new LinearLayout.LayoutParams((int)(mPod.getWidth()*d),(int)(mPod.getHeight()*d)); Log.d(TAG,"LinLay, W,H,T,L: "+mPod.getWidth()+", "+mPod.getHeight()+", "+mPod.getLeft()+", "+mPod.getTop()); linearParams.setMargins(mPod.getLeft(), mPod.getTop(), 0,0); linearToAdd.setLayoutParams(linearParams); ShapeDrawable rectShapeDrawable1 = new ShapeDrawable(); Paint paint1 = rectShapeDrawable1.getPaint(); // paint1.setColor(Color.rgb(0, 0, 0)); paint1.setStyle(Paint.Style.STROKE); paint1.setStrokeWidth(3); // linearToAdd.setBackgroundDrawable(rectShapeDrawable1); break; }

推荐答案

您可以尝试通过GradientDrawable进行操作.我尝试了这个.希望对您有帮助.

You can try doing it by GradientDrawable. I tried this one. Hope it might help you.

GradientDrawable drawable = new GradientDrawable(); drawable.setShape(GradientDrawable.RECTANGLE); drawable.setStroke(3, Color.BLACK); drawable.setCornerRadius(8); drawable.setColor(Color.BLUE); linearToAdd.setBackgroundDrawable(drawable);

在您的XML布局中，将android:padding ="1dp"设置为linearToAdd.

In your XML layout give android:padding="1dp" to linearToAdd.
