androidwebView截图的4种方法-创新互联

android 在webView里面截图大概有四种方式，具体内容如下

1.获取到DecorView然后将DecorView转换成bitmap然后写入到文件里面.

View view = getWindow().getDecorView();
  Bitmap bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), Bitmap.Config.ARGB_8888);
   Canvas canvas = new Canvas(bitmap);
    view.draw(canvas);
    Log.d(TAG,"bitmap--"+bitmap);
    try {
      String fileName = Environment.getExternalStorageDirectory().getPath()+"/webview_jietu.jpg";
      FileOutputStream fos = new FileOutputStream(fileName);
      //压缩bitmap到输出流中
      bitmap.compress(Bitmap.CompressFormat.JPEG, 70, fos);
      fos.close();
      Toast.makeText(WebviewFromGetDecorView.this, "截屏成功", Toast.LENGTH_LONG).show();

    } catch (Exception e) {
      Log.e(TAG, e.getMessage());
    }finally {
      if(bitmap!=null) {
     bitmap.recycle();
 }

}
