Android应用截图两种方法

view.setDrawingCacheEnabled(true);
view.buildDrawingCache();  //启用DrawingCache并创建位图
Bitmap bitmap = Bitmap.createBitmap(view.getDrawingCache()); //创建一个DrawingCache的拷贝，因为DrawingCache得到的位图在禁用后会被回收
view.setDrawingCacheEnabled(false);  //禁用DrawingCahce否则会影响性能

	private void layoutView(View v, int width, int height) {
		// validate view.width and view.height
		v.layout(0, 0, width, height);
		int measuredWidth = View.MeasureSpec.makeMeasureSpec(width, View.MeasureSpec.EXACTLY);
		int measuredHeight = View.MeasureSpec.makeMeasureSpec(height, View.MeasureSpec.EXACTLY);
		// validate view.measurewidth and view.measureheight
		v.measure(measuredWidth, measuredHeight);
		v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());i
	}

int viewWidth = webView.getMeasuredWidth();
int viewHeight = webView.getMeasuredHeight();
if (viewWidth > 0 && viewHeight > 0) {
	b = Bitmap.createBitmap(viewWidth, viewHeight, Config.ARGB_8888);
	Canvas cvs = new Canvas(b);
	webView.draw(cvs);
