以编程方式更改Android EditText的颜色 [英] Changing tint color of Android EditText programmatically

问题描述

我试图在运行时以编程方式更改 EditText 视图的着色颜色.基本上，我想更改通常用作?attr/colorControlNormal 的内容，例如 1中指定的Alpha开头是可见的.

这是仅在第一个 EditText 上设置色彩颜色的结果:

所以我的问题是:如何以编程方式将着色正确地应用于 EditText ?

解决方案

使用新引入的 android.support.v4.graphics.drawable.DrawableCompat#setTint 可以设置颜色.

I am trying to change the tinting color of an EditText View programmatically during runtime. Basically i want to change what you would usually apply as ?attr/colorControlNormal like in the default background drawable.

Changing the background tint does not correctly apply by just setting a new ColorsStateList with one color:

editText.setBackgroundTintList( ColorStateList.valueOf( color ) );

For one the result is applied to all EditText although the tint list is applied and internally mutates the drawable. Also the alpha as specified in the default background 1 is visible at the beginning.

Here is the outcome of setting the tint color on just the first EditText:

So my question would be: How can I properly apply the tint programmatically to an EditText?

解决方案

With the newly introduced android.support.v4.graphics.drawable.DrawableCompat#setTint setting the color is now possible.
