Android 根据View(布局) 生成图片(Bitmap)_android view.inflate生成长图bitmap

下面生成图片的方法我会引用一个布局,布局我就不贴了,我说一些大家要主要的地方

布局:
引用了R.layout.ll_bitmap这个xml文件的布局
这个id (R.id.ll_layout)是最外面的一个布局 最好是LayoutInflater ,如果有其他的都布局请在外面写一个.要不然很容易出问题(RelativeLayout)

生成图片

    private Bitmap getBitmap() {
            Bitmap bitmap = null;
            LayoutInflater factorys = LayoutInflater.from(this);
            final View textEntryView = factorys.inflate(R.layout.ll_bitmap, null);
            View ll = textEntryView.findViewById(R.id.ll_layout);

            TextView textView = (TextView) textEntryView.findViewById(R.id.tvbitmap_sfz);
            textView.setTypeface(Typeface.createFromAsset(getAssets(), "fonts/OCRB10N.TTF"));
            ll.setDrawingCacheEnabled(true);
            ll.measure(View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED),
                    View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
            ll.layout(0, 0, ll.getMeasuredWidth(), ll.getMeasuredHeight());
            bitmap = Bitmap.createBitmap(ll.getDrawingCache());
            ll.setDrawingCacheEnabled(false);

            return bitmap;
        }

这个是上面的Bitmap存到sd卡里面 大家自己根据情况写

权限:<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

        private void saveCroppedImage(Bitmap bmp) {
                File file = new File("/sdcard/myFolder");
                if (!file.exists())
                    file.mkdir();

                file = new File("/sdcard/temp.jpg".trim());
                String fileName = file.getName();
                String mName = fileName.substring(0, fileName.lastIndexOf("."));
                String sName = fileName.substring(fileName.lastIndexOf("."));

                // /sdcard/myFolder/temp_cropped.jpg
                String newFilePath = "/sdcard/myFolder" + "/" + mName + "_cropped" + sName;
                file = new File(newFilePath);
                try {
                    file.createNewFile();
                    FileOutputStream fos = new FileOutputStream(file);
                    bmp.compress(CompressFormat.JPEG, 50, fos);
                    fos.flush();
                    fos.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

            }
