Echart在Android中的简单使用

没有找到相应的x与y轴单位的设置方法

• 将生成好的html文件放入到 assets目录下，记得导入相应的js库，因为Echart的实现是有js实现的。可以去官网去下载相应的js库
• 使用WebView加载我们生成的网页
• 具体的操作方法如下

        WebSettings webSettings = wvHdZxchart.getSettings();
        webSettings.setAllowFileAccess(true);
        webSettings.setSupportZoom(true);
//      webSettings.setCacheMode(WebSettings.LOAD_NO_CACHE);
        // 开启脚本支持
        webSettings.setJavaScriptEnabled(true);
        wvHdZxchart.setBackgroundColor(0);
        
        wvHdZxchart.loadUrl("file:///android_asset/echart/zx_line.html");
        
        wvHdZxchart.setWebViewClient(new WebViewClient(){
            @Override
            public void onPageFinished(WebView view, String url) {
                view.loadUrl("javascript:createMpieChart();");
            }
        });

这样，在Android客户端就可以轻松实现各种PC图表，也可以通过js对象，动态的切换图表中相应的数据源。

show:false : 鼠标悬浮上面不显示相应的数值信息
silent:true : 打开鼠标点击实事件，如果是空实现，没有任何效果（反之屏蔽掉所有的相应的鼠标滑过的事件，或者放大的效果等）
hoverAnimation:false ：鼠标悬浮放大的效果展示
