我想挽救AndroidPlot一个PNG图片 [英] I want to save a .png image from AndroidPlot

问题描述

我已经写了code这绘制的线图。
此图是采用Android绘制曲线..
我该如何拯救这个图作为PNG图片??

解决方案

  xyPlot.setDrawingCacheEnabled（真）;
        INT宽度= xyPlot.getWidth（）;
        INT高度= xyPlot.getHeight（）;
        xyPlot.measure（宽度，高度）;
        BMP位图= Bitmap.createBitmap（xyPlot.getDrawingCache（））;
        xyPlot.setDrawingCacheEnabled（假）;
        FOS的FileOutputStream =新的FileOutputStream（fullFileName，真）;
        bmp.com preSS（比较pressFormat.JPEG，100，FOS）;

解决方案

        xyPlot.setDrawingCacheEnabled(true);
        int width = xyPlot.getWidth();
        int height = xyPlot.getHeight();
        xyPlot.measure(width, height);
        Bitmap bmp = Bitmap.createBitmap(xyPlot.getDrawingCache());
        xyPlot.setDrawingCacheEnabled(false);
        FileOutputStream fos = new FileOutputStream(fullFileName, true);
        bmp.compress(CompressFormat.JPEG, 100, fos);
