好吧，终于我找到了可行的解决方案。
这个想法：用户在800x800像素大小的图像上添加文本视图，用它做点什么，然后我需要获得相同的图像，但像素为2000x2000像素。问题是-
调整大小后，文本模糊且嘈杂。但是，我该如何截取屏幕尺寸大于屏幕的未渲染视图的屏幕截图？
我在这里使用的代码工作得很好，我得到相同的图像，相同位置的文本，相同的大小等，但没有调整大小的噪音，文本看起来清晰且不模糊。另外，此代码保存的位图比屏幕大小大得多，并且没有向用户显示。
private Bitmap makeTextLayer(int maxWidth, int maxHeight, ImageObject imageObject) { Context c = mContext; View v = LayoutInflater.from(c).inflate(R.layout.text_view_generator, new LinearLayout(c), false); RelativeLayout editTexts = (RelativeLayout) v.findViewById(R.id.editTexts); initView(v, maxWidth, maxHeight); for (int i = 0; i < imageObject.getEditTexts().size(); ++i) { ImageObject.TextInImage textInImage = imageObject.getEditTexts().get(i); //text view in relative layout - init his size, in my case it's as big as image CustomEditText editText = new CustomEditText(c); RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT, RelativeLayout.LayoutParams.FILL_PARENT); params.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE); // don't forget to add your view to layout, this view will be saved as screenshot editTexts.addView(editText, params); editText.getLayoutParams().width = maxWidth; editText.getLayoutParams().height = maxHeight; editText.loadTextParams(textInImage); editText.loadSizeAndRotation(textInImage); // this is important, without new init - position of text will be wrong initView(v, maxWidth, maxHeight); // and here i configure position editText.loadPosition(); } Bitmap result = getViewBitmap(v, maxWidth, maxHeight); return result; } Bitmap getViewBitmap(View v, int maxWidth, int maxHeight) { //Get the dimensions of the view so we can re-layout the view at its current size //and create a bitmap of the same size int width = v.getWidth(); int height = v.getHeight(); int measuredWidth = View.MeasureSpec.makeMeasureSpec(width, View.MeasureSpec.EXACTLY); int measuredHeight = View.MeasureSpec.makeMeasureSpec(height, View.MeasureSpec.EXACTLY); //Cause the view to re-layout v.measure(measuredWidth, measuredHeight); v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight()); //Create a bitmap backed Canvas to draw the view into Bitmap b = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888); Canvas c = new Canvas(b); //Now that the view is laid out and we have a canvas, ask the view to draw itself into the canvas v.draw(c); return b; } private void initView(View view, int maxWidth, int maxHeight){ ViewGroup.LayoutParams vParams = view.getLayoutParams(); //If the View hasn't been attached to a layout, or had LayoutParams set //return null, or handle this case however you want if (vParams == null) { return; } int wSpec = measureSpecFromDimension(vParams.width, maxWidth); int hSpec = measureSpecFromDimension(vParams.height, maxHeight); view.measure(wSpec, hSpec); int width = view.getMeasuredWidth(); int height = view.getMeasuredHeight(); //Cannot make a zero-width or zero-height bitmap if (width == 0 || height == 0) { return; } view.layout(0, 0, width, height); } private int measureSpecFromDimension(int dimension, int maxDimension) { switch (dimension) { case ViewGroup.LayoutParams.MATCH_PARENT: return View.MeasureSpec.makeMeasureSpec(maxDimension, View.MeasureSpec.EXACTLY); case ViewGroup.LayoutParams.WRAP_CONTENT: return View.MeasureSpec.makeMeasureSpec(maxDimension, View.MeasureSpec.AT_MOST); default: return View.MeasureSpec.makeMeasureSpec(dimension, View.MeasureSpec.EXACTLY); } }如果我的解决方案对您不起作用，我在阅读它们时会找到解决方案-请查看此信息。
