在android中，如何在不重塑的情况下将线性布局转换为位图？

我正在为pax打印机开发一个应用程序，所以我需要将我的xml布局（线性、相对…）转换为位图，我的问题是，当我将任何布局转换为图像时，创建的位图宽度大小将被重新塑造。为什么会发生这种情况？我怎样才能解决这个问题？ 这是我的转换代码：

LayoutInflater lInflater = (LayoutInflater)getApplicationContext().getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
View view = lInflater.inflate(R.layout.testlayout, null);
view.setDrawingCacheEnabled(true);
view.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED),View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
view.buildDrawingCache(true);
Bitmap b = Bitmap.createBitmap(view.getDrawingCache());
view.setDrawingCacheEnabled(false); // clear drawing cache
imgview.setImageBitmap(b);
storeImage(b); 

我尝试了许多其他的转换方法，但我得到了同样的结果。 这是我的布局之一：

        </LinearLayout>

    </FrameLayout>

</LinearLayout>

请注意，无论布局、文本视图、图像视图，。。。或者我用的是哪种布局类型。都是同样的问题

感谢您的帮助

尝试一下：

public static Bitmap view2Bitmap(final FrameLayout view) {
        if (view == null) return null;
        boolean drawingCacheEnabled = view.isDrawingCacheEnabled();
        boolean willNotCacheDrawing = view.willNotCacheDrawing();
        view.setDrawingCacheEnabled(true);
        view.setWillNotCacheDrawing(false);
        Bitmap drawingCache = view.getDrawingCache();
        Bitmap bitmap;
        if (null == drawingCache) {
            view.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED),
                    View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
            view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
            view.buildDrawingCache();
            drawingCache = view.getDrawingCache();
            if (drawingCache != null) {
                bitmap = Bitmap.createBitmap(drawingCache);
            } else {
                bitmap = Bitmap.createBitmap(view.getMeasuredWidth(), view.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
                Canvas canvas = new Canvas(bitmap);
                view.draw(canvas);
            }
        } else {
            bitmap = Bitmap.createBitmap(drawingCache);
        }
        view.destroyDrawingCache();
        view.setWillNotCacheDrawing(willNotCacheDrawing);
        view.setDrawingCacheEnabled(drawingCacheEnabled);
        return bitmap;
    }

您好，我尝试了您的方法，但不起作用。结果相同。奇怪的是，我复制了您的代码，一切正常，我可以在

ImageView

中看到

bitmap

显示，您的意思是创建的位图可以吗？奇怪。我很困惑。这个代码有什么问题！是的，我试过使用

FrameLayout

引用的

printing

id
