Android以編程方式將Shape設置爲ShapeDrawable

Question

我可以以編程方式將Shape設置爲ShapeDrawable嗎？

Answer 1

你可以這樣說：

public static void customView(View v, int backgroundColor, int borderColor) 
{ 
    GradientDrawable shape = new GradientDrawable(); 
    shape.setShape(GradientDrawable.RECTANGLE); 
    shape.setCornerRadii(new float[] { 8, 8, 8, 8, 0, 0, 0, 0 }); 
    shape.setColor(backgroundColor); 
    shape.setStroke(3, borderColor); 
    v.setBackgroundDrawable(shape); 
} 

您可以使用此功能在您的應用程序，並可以把邊框和背景顏色你的選擇。

試試這個：

 LayerDrawable bgDrawable = (LayerDrawable) btnCallnow.getBackground(); 
     final GradientDrawable shape = (GradientDrawable) bgDrawable.findDrawableByLayerId(R.id.shape_id); 
     shape.setCornerRadius(5.0f);
