使用密码切换显示或隐藏文本

Question

我正在使用以下代码显示或隐藏密码

pwdLayout.setEndIconMode(TextInputLayout.END_ICON_PASSWORD_TOGGLE);

我可以实现显示或隐藏密码。但是带叉号的眼睛图标显示密码，没有叉号的眼睛图标隐藏密码。我需要反转这个逻辑怎么办？

Answer 1

从 1.2.0 开始，这是默认行为：

如果你想反转图标，你可以使用类似的东西：

    <com.google.android.material.textfield.TextInputLayout
        app:endIconDrawable="@drawable/custom_password_eye"

与：

    <animated-selector xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        tools:ignore="NewApi">
    
        <item
            android:id="@+id/visible"
            android:drawable="@drawable/design_ic_visibility"
            android:state_checked="true"/>
    
        <item
            android:id="@+id/masked"
            android:drawable="@drawable/design_ic_visibility_off"/>
    
        <transition
            android:drawable="@drawable/avd_show_password"
            android:fromId="@id/masked"
            android:toId="@id/visible"/>
    
        <transition
            android:drawable="@drawable/avd_hide_password"
            android:fromId="@id/visible"
            android:toId="@id/masked"/>
    
    </animated-selector>

默认密码应该被隐藏所以 design_ic_visibility_off 应该排在第一位。

<!-- your TextInputLayout -->
<com.google.android.material.textfield.TextInputLayout
    app:endIconDrawable="@drawable/my_custom_password_eye"

Answer 3

最简单的方法。

<com.google.android.material.textfield.TextInputLayout
            android:id="@+id/text_input_password"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:errorEnabled="true"
            app:passwordToggleEnabled="true">

            <com.google.android.material.textfield.TextInputEditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="Password"
                android:inputType="textPassword"
                android:backgroundTint="@color/colorPrimary"
                android:textColor="@color/colorPrimaryDark"/>

</com.google.android.material.textfield.TextInputLayout>
