Answer 1

您必须先点击两个drawable，然后在点击按钮或下面的任何其他事件时动态更改drawable图片，您可以在drawable中设置EditText，如下所示：< / p>

Drawable img = getContext().getResources().getDrawable( R.drawable.smiley );
editText.setCompoundDrawablesWithIntrinsicBounds( null, null, img, null);

“材料成分”从 1.2.0-beta01 开始，这是默认行为：

使用以前的版本，您可以执行以下操作：

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

其中custom_password_eye.xml是：

<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_off"
        android:state_checked="true"/>

    <item
        android:id="@+id/masked"
        android:drawable="@drawable/design_ic_visibility"/>

    <transition
        android:drawable="@drawable/avd_hide_password"
        android:fromId="@id/masked"
        android:toId="@id/visible"/>

    <transition
        android:drawable="@drawable/avd_show_password"
        android:fromId="@id/visible"
        android:toId="@id/masked"/>

</animated-selector>

最新答案。
Probably, google decided to indicate state button instead of action button
因此，如果需要操作按钮，则只需使用xml布局即可自定义图标可绘制，而无需以编程方式进行更改。
将此添加到TextInputLayout：

app:passwordToggleDrawable="@drawable/eye_password"

或在使用material：1.1.0或更高版本时添加此

app:endIconDrawable="@drawable/eye_password"

然后为eye_password创建新的可绘制对象：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ic_eye_close" android:state_checked="true"/>
    <item android:drawable="@drawable/ic_eye_open"/>
</selector>

ic_eye_open的可绘制对象：

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportWidth="24.0"
    android:viewportHeight="24.0">
    <path
        android:fillColor="#FF000000"
        android:pathData="M12,4.5C7,4.5 2.73,7.61 1,12c1.73,4.39 6,7.5 11,7.5s9.27,-3.11 11,-7.5c-1.73,-4.39 -6,-7.5 -11,-7.5zM12,17c-2.76,0 -5,-2.24 -5,-5s2.24,-5 5,-5 5,2.24 5,5 -2.24,5 -5,5zM12,9c-1.66,0 -3,1.34 -3,3s1.34,3 3,3 3,-1.34 3,-3 -1.34,-3 -3,-3z"/>
</vector>

ic_eye_close的可绘制对象：

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="24dp"
    android:height="24dp"
    android:viewportWidth="24.0"
