详细的聊天功能请查看Kotlin高仿微信-第8篇-单聊,这里是提取图片功能的部分实现。
实现代码:
显示图片:
<androidx.appcompat.widget.AppCompatImageViewandroid:id="@+id/chat_item_me_img"app:layout_constraintEnd_toStartOf="@+id/chat_item_me_avatar"app:layout_constraintTop_toTopOf="parent"android:layout_width="100dp"android:layout_height="200dp"android:scaleType="centerCrop"android:layout_marginEnd="10dp"android:src="@drawable/wc_loading_default"android:visibility="gone"/>
打开相册:
//单选 // 打开相册 ImageSelector.builder().useCamera(false) // 设置是否使用拍照.setSingle(true) //设置是否单选.canPreview(true) //是否点击放大图片查看,,默认为true.start(this,REQUEST_PICTURE_CODE)
