然后简单说明一下，嫌我啰嗦的请跳过

request_icon_spacing，icon和文本之间的间隔默认0px

request_icon_color，icon的颜色默认白色

request_icon_size，画笔Paint的width默认5px

request_icon_style：

1.tick_start_circle，最后的画圈和打钩一起进行

2.tick_half_circle，最后的画圈画到一半开始打钩

3.tick_end_circle，最后的画圈画完之后再打钩，默认tick_start_circle

request_speed_multiplier，动画画圈和打钩的速度乘数0.5-2.0，默认1.8

text_default，按钮默认文本，默认“default”

text_progress，请求时文本，默认“progress”

text_success，成功时文本，默认“success”

text_failure，失败时文本，默认“failure”

text_color,文本字体颜色，默认黑色

text_size，文本字体尺寸，默认20px

text_width，文本宽度，默认wrap_content

end2.setOnRequestCallback(new OnRequestCallback() {    
    @Override
    public boolean beforeRequest() {
        return true;
    }
    @Override    
    public void onRequest() {        
        Toast.makeText(MainActivity.this, "request", Toast.LENGTH_SHORT).show();    
    }    
    @Override    
    public void onFinish(boolean isSuccess) {
        Toast.makeText(MainActivity.this, "finish", Toast.LENGTH_SHORT).show();    
    }
});

不需要自己设置OnClickListener，beforeRequest()返回true开始请求，返回false不进行请求。在onRequest()里进行请求，成功或失败后手动调用requestSuccess()或者requestFailure()，等到icon画完就会回调到onFinish()

end2.requestSuccess();
end2.requestFailure();
