问题描述

我有 TextView 和 drawableLeft &列表项中的 drawableRight.问题是，每当 TextView 的高度较大时，drawableLeft &drawableLeft 没有根据 TextView 的高度自动缩放.

I have TextView with drawableLeft & drawableRight in List item. The problem is, whenever the height of TextView is larger, drawableLeft & drawableLeft didn't automatically scale based on the height of the TextView.

drawableLeft & 的高度是否可以缩放?TextView 中的 drawableRight ?(我使用的是 9 个补丁图像)

Is it possible to scale the height of drawableLeft & drawableRight in TextView ? (I was using 9 patch image)

推荐答案

这可能会对您有所帮助.有两个属性 scaleX 和 scaleY

This might help you out. There are two properties scaleX and scaleY

下面的代码会将图片和文字缩小 30%.因此，您必须使用那么多sp"来增加字体大小，以便在重新调整大小(缩放)时适合您喜欢的sp".

The code below will scale down the image and the text with 30%. Therefore you have to increase the font size with that many "sp", so that when it get re-sized (scaled) it would fit the "sp" you prefer.

示例.如果我将字体设置为 18，那么 18 中的 30% 是 5.4sp，所以粗略地说，这就是我的目标值，因为当它被缩放时，它会变成 13sp

Example. If I set the font to 18, then 30% out of 18 is 5.4sp, so roughly, this is the value I am targeting at, because when it gets scaled, it would become 13sp

<TextView
        android:textSize="18sp"
        android:scaleX="0.7"
        android:scaleY="0.7"

最后要做的是设置 CompundDrawable.

The last thing to do is set the CompundDrawable.

tview.setCompoundDrawablesWithIntrinsicBounds(getResources().getDrawable(R.drawable.xxx), null, null, null);
