无法扩展可绘制与ScaleDrawable [英] Unable to scale Drawable with ScaleDrawable

问题描述

与ScaleDrawable不工作对我来说缩放。
提拉残留在相同的尺寸。

Scaling with ScaleDrawable is not working for me.
The drawable is remained in the same size.

LayerDrawable layerDrawable = new LayerDrawable(layers);        
Drawable d = layerDrawable.getCurrent();
ScaleDrawable sd = new ScaleDrawable(d, 0, 0.01f, 0.01f); 
return sd.getDrawable();

我需要做什么来解决呢？
谢谢你。

What i need to do to fix it?
Thanks.

推荐答案

您需要设置<一个href="http://developer.android.com/reference/android/graphics/drawable/Drawable.html#setLevel%28int%29"相对=nofollow>级别：

LayerDrawable layerDrawable = new LayerDrawable(layers);        
Drawable d = layerDrawable.getCurrent();
ScaleDrawable sd = new ScaleDrawable(d, 0, 0.01f, 0.01f); 
sd.setLevel(8000);
return sd;

该电平范围从0到10000：10000是全尺寸的，在0它不会出现在所有

The level ranges from 0 to 10000: at 10000 it is full size, at 0 it does not appear at all.
