Android EditText显示图标

实现了要给带清除按钮的ClearEditText，但是无法显示图标

<androidx.constraintlayout.widget.ConstraintLayout
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:layout_gravity="center">

       <ImageView
           android:id="@+id/iconImageViewKey"
           android:layout_width="24dp"
           android:layout_height="24dp"
           android:src="@drawable/ic_baseline_key_24"
           app:tint="@color/grid"
           android:contentDescription="Icon"
           app:layout_constraintStart_toStartOf="parent"
           app:layout_constraintTop_toTopOf="parent"
           app:layout_constraintBottom_toBottomOf="parent" />

       <com.tools.qrtestassist.component.ClearEditText
           android:id="@+id/password"
           android:layout_width="0dp"
           android:layout_height="wrap_content"
           android:hint="请输入密码"
           android:drawablePadding="8dp"
           android:inputType="text"
           android:maxLength="10"
           app:layout_constraintStart_toEndOf="@id/iconImageViewKey"
           app:layout_constraintEnd_toEndOf="parent"
           app:layout_constraintTop_toTopOf="parent"
           app:layout_constraintBottom_toBottomOf="parent"
           app:layout_constraintBaseline_toBaselineOf="@id/iconImageViewKey" /> <!-- 使用这个属性进行垂直对齐 -->
   </androidx.constraintlayout.widget.ConstraintLayout>

这样写图标在线外不太好看，从新修改ClearEditText

最终效果

同时支持x按钮
