本文實例講述了Android實現將View保存成Bitmap的方法。分享給大家供大家參考，具體如下：
1、
public Bitmap convertViewToBitmap(View view){ Bitmap bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), Bitmap.Config.ARGB_8888); //利用bitmap生成畫布 Canvas canvas = new Canvas(bitmap); //把view中的內容繪制在畫布上 view.draw(canvas); return bitmap;}2、
/*** save view as a bitmap*/private Bitmap saveViewBitmap(View view) {// get current view bitmap view.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 cache view.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;}新聞熱點
