截取屏幕中WebView的图片。

//截取你的WebView图片
        private Bitmap takeWebViewShot(Activity activity){
            int width = webView.getMeasuredWidth();
            int height = webView.getMeasuredHeight();
            Bitmap bm = Bitmap.createBitmap(width,height,Bitmap.Config.ARGB_8888);
            Canvas canvas = new Canvas(bm);
            webView.draw(canvas);
            return bm;
        }

保存图片文件到你的本地相册。

public static void saveImageToGallery(Context context, Bitmap bmp) {
            // 首先保存图片
            File appDir = new File(Environment.getExternalStorageDirectory(), "DCIM");
            if (!appDir.exists()) {
                appDir.mkdir();
            }
            String fileName = System.currentTimeMillis() + ".jpg";
            File file = new File(appDir, fileName);
            try {
                FileOutputStream fos = new FileOutputStream(file);
                bmp.compress(Bitmap.CompressFormat.JPEG, 100, fos);
                fos.flush();
                fos.close();
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
    
            // 其次把文件插入到系统图库
            try {
                MediaStore.Images.Media.insertImage(context.getContentResolver(),
                        file.getAbsolutePath(), fileName, null);
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            }
            // 最后通知图库更新
            context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://" + file.getAbsolutePath())));
        }
