如果 EditText inside 被禁用，如何更改 TextInputLayout 的浮动提示颜色

问题描述

我将 EditText 与 TextInputLayout 一起使用.如果 EditText 被禁用，我只想更改 TextInputLayout 的浮动提示颜色.我尝试使用选择器它不起作用.

I am using EditText with TextInputLayout. I just want to change the floating hint color of TextInputLayout if the EditText is disabled. I tried with selector it is not working.

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_enabled="false" android:textColor="@color/darkGray" />
    <item android:state_pressed="false" android:state_focused="false" android:textColor="@color/lightGray"/>
</selector>

推荐答案

在 TextInputLayout 类中有一个名为 setHintTextAppearance(int styleId) 的方法.您可以使用此方法根据启用/禁用状态设置不同的颜色以提示文本.

There's one method called setHintTextAppearance(int styleId) in TextInputLayout class. You can use this method to set difference colors to hint text on basis of enabled/disabled state.

例子:

//for disabled editText
mEditText.setEnabled(false);
mTextInoutLayout.setHintTextAppearance(R.style.CustomHintDisabled);

//for enablededitText
mEditText.setEnabled(true);
mTextInoutLayout.setHintTextAppearance(R.style.CustomHintEnabled);

在你的 styles.xml

<style name="CustomHintDisabled" parent="YourBaseTheme.TextAppearance">
    <item name="textColor">@color/gray</item>
</style>

<style name="CustomHintEnabled" parent="YourBaseTheme.TextAppearance">
    <item name="textColor">@color/black</item>
</style>
