# 仿即刻APP点赞桃心的效果
## 2016-12-5更新
- 修改测量逻辑
- 添加了对齐方式
- 添加了一个评论图形的GraphAdapter
- 修改了已知BUG
## 先看效果图
## 使用方法
### 布局配置
```
```
> 注意,一般不需要直接指定宽高,内部会根据字体大小自动测量
### 代码配置
```java
//点赞view的设置
holder.like.setActivated(entity.isLike);
holder.like.setNumber(entity.likeNum);
holder.like.setCallback(new LikeView.SimpleCallback() {
@Override
public void activate(LikeView view) {
Snackbar.make(view, "你觉得" + entity.name + "很赞!", Snackbar.LENGTH_SHORT).show();
}
@Override
public void deactivate(LikeView view) {
Snackbar.make(view, "你取消了对" + entity.name + "的赞!", Snackbar.LENGTH_SHORT).show();
}
});
//评论view的设置
holder.comment.setNumber(entity.commentNum);
//设置图形适配器
holder.comment.setGraphAdapter(CommentPathAdapter.getInstance());
holder.comment.setCallback(new LikeView.SimpleCallback(){
@Override
public boolean onClick(LikeView view) {
Snackbar.make(view, "你点击" + entity.name + "的评论按钮", Snackbar.LENGTH_SHORT).show();
//返回true代表拦截此次点击,不使用默认的点击事件
return true;
}
});
```
### 自定义图形适配器
```java
public class CommentPathAdapter implements LikeView.GraphAdapter {
private static CommentPathAdapter instance;
private static final float xOffsetScale = 0.06f;
private static final float yOffsetScale = 0.2f;
//可用单例模式
public static CommentPathAdapter getInstance() {
synchronized (CommentPathAdapter.class) {
if (null == instance) {
instance = new CommentPathAdapter();
}
}
return instance;
}
//这里绘制你想要的图形
@Override
public Path getGraphPath(LikeView view, int length) {
Path path = new Path();
int dx = (int) (length * xOffsetScale);
int dy = (int) (length * yOffsetScale);
int w = (int) (length * (1 - xOffsetScale * 2));
int h = (int) (length * (1 - yOffsetScale * 2));
path.moveTo(dx, dy);
path.lineTo(dx + w, dy);
path.lineTo(dx + w, dy + h);
path.lineTo(dx + (w * 0.35f), dy + h);
path.lineTo(dx + (w * 0.1f), dy + (h * 1.4f));
path.lineTo(dx + (w * 0.1f), dy + h);
path.lineTo(dx, dy + h);
path.lineTo(dx, dy);
return path;
}
}
```
## 自定义配置
```
```
## 接口
```java
/**
* 事件监听接口
*/
public interface Callback {
/**
* 点击事件监听
*
* @param view 当前View
* @return 返回true则代表不使用默认的点击事件
*/
boolean onClick(LikeView view);
/**
* 变为激活状态
*
* @param view 当前View
*/
void activate(LikeView view);
/**
* 变为不激活状态
*
* @param view 当前View
*/
void deactivate(LikeView view);
}
/**
* 获取图形Path接口
*/
public interface GraphAdapter {
/**
* 获取图形的Path
*
* @param view 当前View
* @param length 可绘制图形区域正方形的边长
* @return 带有图形的Path
*/
Path getGraphPath(LikeView view, int length);
}
```
