Answer 1

好吧,我找到了正确的答案,有一种方法可以自定义它的颜色. https://developer.android.com/reference/android/support/design/widget/TextInputLayout.html#attr_android.support.design:passwordToggleTint

setPasswordVisibilityToggleTintList(ColorStateList)

更新:您可以在TextInputLayout中直接添加以下属性:

app:passwordToggleTint="#FFF"

Answer 2

rapid3642的答案指向正确的方向,但我仍然需要找出究竟会起作用的方法.

请按照以下步骤更改切换画面的颜色:

1. 创建selector_password_visibility_toggle于~/res/color/:

   <?xml version="1.0" encoding="utf-8"?>
   <selector xmlns:android="http://schemas.android.com/apk/res/android">
       <!-- When password is shown as text, the drawable will be off_white coloured -->
       <item android:color="@color/off_white" android:state_checked="true"/>
       <item android:color="@android:color/white"/>
   
   </selector>
   

2. 添加passwordToggleTintMode和passwordToggleTint你的TextInputLayout,如下:

   <android.support.design.widget.TextInputLayout
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       app:passwordToggleTintMode="src_atop"
       app:passwordToggleTint="@color/selector_password_visibility_toggle"
       app:passwordToggleEnabled="true">
   

现在你的TextInputLayout遗嘱颜色会改变.

Answer 3

在您的布局中添加以下xmlns：app。

xmlns:app="http://schemas.android.com/apk/res-auto"

现在在EditText中相应地设置passwordToggleEnabled 和 passwordToggleTint

app:passwordToggleEnabled = "true"
app:passwordToggleTint="#FFFFFF"

Answer 4

这是一种以编程方式执行此操作的好方法：

setPasswordVisibilityToggleTintList(AppCompatResources.getColorStateList(context, R.color.white));

在TextInputLayout对象上调用此方法。
