Question

正如你在图片中看到的，我有一个黑色背景和白色文本的Android应用程序。然而实际上有一个＆＃34; Show Text＆＃34;看起来像眼睛的图标＆＃34;并且它也是黑色的:(。有没有办法改变它的颜色？

        <item name="android:textColorHint">#ffffff</item>

</resources>

Answer 1

Ok guys I found the right answer, there IS a way to customize the color of it. https://developer.android.com/reference/android/support/design/widget/TextInputLayout.html#attr_android.support.design:passwordToggleTint

setPasswordVisibilityToggleTintList(ColorStateList)

Update: You can directly add following attribute in the TextInputLayout:

app:passwordToggleTint="#FFF"

Answer 2

rapid3642的回答指出了正确的方向，但我仍然需要找出究竟会起作用的方法。

按照以下步骤更改切换画面的颜色：

在selector_password_visibility_toggle中创建~/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>

将passwordToggleTintMode和passwordToggleTint添加到您的TextInputLayout，如下所示：

<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">

现在您的TextInputLayout将更改其可绘制颜色。

Answer 3

在布局中添加以下xmlns：app。

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

现在相应地在EditText中设置 passwordToggleEnabled ＆amp; passwordToggleTint

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

Answer 4

这是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。

Answer 5

Create a custom Style.

<style name="PasswordText" parent="TextAppearance.AppCompat">
    <item name="android:textColor">@color/dt_login_text</item>
    <item name="android:textColorPrimary">@color/dt_login_text</item>
</style>

XML Code. // This will change the password mask color.

<android.support.v7.widget.AppCompatEditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="@dimen/padding_6"
            android:theme="@style/PasswordText"
            android:layout_margin="@dimen/margin_3"
            android:gravity="center"
            android:inputType="textPassword"
            android:text="Q"/>

Answer 6

添加可绘制文件selector.xml：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@color/dim_orange_btn_pressed" />
    <item android:state_focused="true" android:drawable="@color/dim_orange_btn_pressed" />
    <item android:drawable="@android:color/white" />
</selector>

将此行android:background="@drawable/selector"

添加到您的EditText中

    <LinearLayout
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
           <EditText android:id="@+id/txt_pass"
            android:theme="@style/MyEditTextTheme"
            android:layout_width="match_parent"
            android:background="@drawable/selector"
            android:layout_height="wrap_content"
           android:inputType="textPassword"
            android:hint="E-Mail Address"/>

        <ImageButton
        android:id="@+id/btn_eye"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:src="@drawable/eye"
        />
   </LinearLayout>

在您的代码中：

buttonEye.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_DOWN) {

            txt_pass.setInputType(InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);

        } else if (event.getAction() == MotionEvent.ACTION_UP) {

             txt_pass.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);
        }
    }
};

Answer 7

如果您使用edittext或texteditlayout的背景，则密码可见性切换隐藏在背景下。因此，删除背景或创建自定义样式，并将其作为xml布局中edittext的主题。

 <style name="EditText_theme" parent="">
        <item name="passwordToggleTintMode">src_over</item>
    </style>

如果你仍然面临问题或者你没有保留任何背景，那么改变应用程序本身的主题，因为那里确定了主要颜色。

这是其他不适用的解决方法。这是我从google docs本身获得的，

 <style name="EditText_theme" parent="">
        <item name="passwordToggleTint">@color/white</item>
    </style>

更改蒙版密码选择器的颜色
