Password toggle button on TextInputEditText disapp

问题:

I have a TextInputEditText in conjunction with TextInputLayout with android:inputType="textPassword" using app:passwordToggleEnabled="true" to show password toggle button in the TextInputEditText like next image:


The problem is once I press the password toggle button, it disappears for ever.
It was working well in com.android.support:design:24.2.0 version.

am I missing something new? it's a bug?

Some gradle project's setup:
minSdkVersion 17
targetSdkVersion 25
compile 'com.android.support:support-v4:25.1.0'
compile 'com.android.support:appcompat-v7:25.1.0'
compile 'com.android.support:cardview-v7:25.1.0'
compile 'com.android.support:design:25.1.0'

Running in 2 different Android 6.0 (Marshmallow) devices.

XML:

<android.support.design.widget.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/TextLabelGray"
    app:passwordToggleEnabled="true">

    <android.support.design.widget.TextInputEditText
        android:id="@+id/profile_field_password"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/perfil_field_password"
        android:inputType="textPassword"
        android:maxLines="1"
        android:maxLength="100"
        android:imeOptions="actionNext"
        android:imeActionLabel="@string/perfil_field_tipo_documento"
        android:textColor="@color/colorAccent"
        android:textSize="@dimen/perfil_text_view_text_size"
        android:paddingStart="15dp"
        android:paddingEnd="5dp"/>
</android.support.design.widget.TextInputLayout>

If I use app:passwordToggleDrawable with a custom drawable in TextInputLayout it doesn't disappear.

The related style:

<style name="TextLabelGray" parent="TextAppearance.AppCompat">
    <!--//hint color And Label Color in False State-->
    <item name="android:textColorHint">@color/gray_text_color</item>
    <item name="android:textColorHighlight">@color/gray_text_color</item>
    <item name="android:textColorLink">@color/gray_text_color</item>
    <item name="colorAccent">@color/gray_text_color</item>
    <item name="colorControlNormal">@color/gray_text_color</item>
    <item name="colorControlActivated">@color/gray_text_color</item>
</style>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="colorControlNormal">@color/colorControlNormal</item>

    <item name="searchViewStyle">@style/AppTheme.MySearchViewStyle</item>
</style>

change gradle file by following dependency

compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:25.3.1'
compile 'com.android.support:support-v4:25.3.1'

In xml file, add following lines for toggle button in password field

 <android.support.design.widget.TextInputLayout
 android:id="@+id/text_input_layout_password"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:layout_marginTop="10dp"
 app:passwordToggleEnabled="true">

          <android.support.design.widget.TextInputEditText
          android:id="@+id/text_input_edit_text_password"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:hint="Enter Password"
          android:imeActionId="@+id/login"
          android:imeActionLabel="Login"
          android:imeOptions="actionUnspecified"
          android:inputType="textPassword"
          android:maxLines="1"
          tools:text="password" />

 </android.support.design.widget.TextInputLayout>

回答2:

Add

<item name="passwordToggleDrawable">@drawable/design_password_eye</item>
<item name="passwordToggleTint">@color/design_tint_password_toggle</item>
<item name="passwordToggleContentDescription">@string/password_toggle_content_description</item>

on your TextLabelGray style and it will show toggle button again.

            android:layout_marginBottom="16sp"
            app:passwordToggleEnabled="true"
            style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox">

            <android.support.design.widget.TextInputEditText
                android:id="@+id/password"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="@string/prompt_password"
                android:imeActionId="6"
                android:inputType="textPassword"
                android:maxLines="1"
                android:fontFamily="@font/product_regular"
                android:singleLine="true" />
