+# QDrawGift
+
+## 简介：
+
+仿快手直播间手绘礼物，手绘+播放+底部礼物弹框，Demo非常完整，非常贴合实际开发场景 。
+A Gift Painter useful in Living Room. Support paint+play+bottomSheet
+
+## 安装体验：
+![](https://upload-images.jianshu.io/upload_images/26002059-83cf0b95754b2466.png)
+
+## 功能（优点）：
+- ✅Demo包含`手绘View`+`播放View`+`底部礼物弹框View`+转成json传给服务器+模拟服务器推送来json解析队列
+- ✅为了兼容底部礼物弹框是基于Dialog或者popupView做的，本Demo的`手绘View`是基于windowManager层
+- ✅`手绘View`可以单独撤销一笔
+- ✅`播放View`使用LinkedList做礼物队列，可以随意插入到列头或者列尾
+- ✅底部礼物弹框兼容手绘礼物和普通礼物，选择不同的礼物，手绘View层可以切换placeHolder
+- ✅每个模块都相互解耦，都可以自由替换，也都可以拉出来当做独立的模块
+- ✅采用SpareArray做Bitmap缓存，占用内存极低
+- ✅无内存泄漏。代码清晰明确，注释量比代码都多

+
+## 使用
+
+```java
+    //底部的礼物弹框
+    private BottomGiftSheetBuilder giftSheetBuilder;
+
+    //画礼物的背景View（透明的，并不是灰底）
+    private DrawGiftView drawGiftView;
+
+    //播放礼物动画的层
+    private DrawGiftPlayView playView;
+```
+
+```java
+    //初始化手绘礼物View
+    drawGiftView = new DrawGiftView(LiveActivity.this);
+    //设置当前要画的礼物
+    drawGiftView.setCurrentGift(giftid ,giftBitmap , giftPrice);
+    //正式显示手绘礼物View，添加它到windowManager层
+    drawGiftView.showInActivityWindow(LiveActivity.this, giftSheetBuilder.mDialog.getContentView().getHeight());
+```
+
+```java
+    //初始化播放View
+    playView = new DrawGiftPlayView(this);
+
+    //添加播放View到decorView
+    FrameLayout contentParent = (FrameLayout) getWindow().getDecorView().findViewById(android.R.id.content);
+    contentParent.addView(playView);
+
+    //开始播放礼物，insertToFirst = 是否插入到队列靠前位置
+    playView.addDrawGifts(allDrawGiftArray, insertToFirst);
+```
