Overview

这个仓库来自 [StickerView][https://github.com/wuapnjie/StickerView], 自己克隆了一份用于学习, 对于使用Matrix进行几何变换和手势检测很有学习的意义. 我在原始仓库的基础上升级了gradle和agp的版本,引入了kotlin, 进行了一些注释, 代码格式化和案例代码的书写.

StickerView

A view which can add sticker and zoom,drag,flip,delete it

I hope you can copy the source code to your project so you can design your own function.

Usage

Suggestion

copy the source code to your project so you can design your own function.

Tips:StickerView extends FrameLayout

In layout

<com.xiaopo.flying.sticker.StickerView
        android:id="@+id/sticker_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center">
    <!-- custom, maybe you will like to put an ImageView--> 
    <ImageView
        android:src="@drawable/haizewang_2"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</com.xiaopo.flying.sticker.StickerView>

Add sticker

If the sticker is drawable, it's intrinsic width and height can not be zero. If the sticker is text, you can set text color, font and alignment and the region which holds the text.

stickerView.addSticker(sticker)
stickerView.replace(sticker)
stickerView.remove(sticker)
stickerView.removeCurrentSticker()
stickerView.removeAllStickers()
stcikerView.setLocked(true)

Also you can custom the icon and icon event and position

 BitmapStickerIcon heartIcon =
        new BitmapStickerIcon(ContextCompat.getDrawable(this, R.drawable.ic_favorite_white_24dp),
            BitmapStickerIcon.LEFT_BOTTOM);
heartIcon.setIconEvent(new HelloIconEvent());

stickerView.setIcons(Arrays.asList(deleteIcon, zoomIcon, flipIcon, heartIcon));
