我正在尝试从下面的图像在Android中构建Button。该按钮当前被实现为Button
,其中ImageView
内的ContraintLayout
可以正常工作。
我现在需要添加一个传递到子ImageView
的波纹效果。使用当前代码,每当我按下Button
时,涟漪效应都会使 + ImageView
消失并重新出现。我想要的是,当涟漪效应达到 + ImageView
时,它会进入元素并在那里传播。当前代码如下:
<android.support.constraint.ConstraintLayout
android:id="@+id/button_attach_camera"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/shape_card_header"
android:backgroundTint="@color/detailsCardBackground"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/finish_input_body_visit_attachments_header_card"
app:layout_constraintBottom_toTopOf="@+id/recycler_attachments">
<android.support.v7.widget.AppCompatButton
android:id="@+id/add_image_from_album"
android:layout_width="100dp"
android:layout_height="74dp"
android:layout_marginStart="40dp"
android:layout_marginEnd="36dp"
android:layout_marginTop="8dp"
android:background="@drawable/shape_status_card"
android:drawableTop="@drawable/ic_gallery"
android:fontFamily="@font/rubik"
android:foreground="?android:attr/selectableItemBackgroundBorderless"
android:paddingBottom="12dp"
android:paddingEnd="12dp"
android:paddingStart="12dp"
android:paddingTop="12dp"
android:text="@string/visit_finish_album_button"
android:textAppearance="@style/TextAppearance.AppCompat"
app:layout_constraintHorizontal_bias="0.0"
app:layout_constraintEnd_toEndOf="parent" />
<android.support.v7.widget.AppCompatImageView
android:id="@+id/add_from_album_button"
android:layout_width="24dp"
android:layout_height="24dp"
android:layout_marginStart="0dp"
android:layout_marginTop="48dp"
android:background="@drawable/shape_rounded_button_no_background"
android:clickable="true"
android:focusable="true"
android:elevation="2dp"
android:src="@drawable/ic_add_circle"
app:layout_constraintStart_toStartOf="@+id/add_image_from_album"
app:layout_constraintTop_toTopOf="@+id/add_image_from_album" />
</android.support.constraint.ConstraintLayout>
