本文实例讲述了Android实现将View保存成Bitmap的方法。分享给大家供大家参考,具体如下:
1、
public Bitmap convertViewToBitmap(View view){Bitmap bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(),Bitmap.Config.ARGB_8888);//利用bitmap生成画布Canvas canvas = new Canvas(bitmap);//把view中的内容绘制在画布上view.draw(canvas);return bitmap;}2、
/*** save view as a bitmap*/private Bitmap saveViewBitmap(View view) {// get current view bitmapview.setDrawingCacheEnabled(true);view.buildDrawingCache(true);Bitmap bitmap = view.getDrawingCache(true);Bitmap bmp = duplicateBitmap(bitmap);if (bitmap != null && !bitmap.isRecycled()) { bitmap.recycle(); bitmap = null; }// clear the cacheview.setDrawingCacheEnabled(false);return bmp;}public static Bitmap duplicateBitmap(Bitmap bmpSrc){if (null == bmpSrc){ return null; }int bmpSrcWidth = bmpSrc.getWidth();int bmpSrcHeight = bmpSrc.getHeight();Bitmap bmpDest = Bitmap.createBitmap(bmpSrcWidth, bmpSrcHeight, Config.ARGB_8888); if (null != bmpDest) { Canvas canvas = new Canvas(bmpDest); final Rect rect = new Rect(0, 0, bmpSrcWidth, bmpSrcHeight);canvas.drawBitmap(bmpSrc, rect, rect, null); }return bmpDest;}更多关于Android相关内容感兴趣的读者可查看本站专题:《Android文件操作技巧汇总》、《Android编程开发之SD卡操作方法汇总》、《Android开发入门与进阶教程》、《Android资源操作技巧汇总》、《Android视图View技巧总结》及《Android控件用法总结》
