android 将View保存成Bitmap

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 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;
	}
