代码示例来源：origin: airbnb/AirMapView

@Override public void getSnapshot(OnSnapshotReadyListener listener) {
  boolean isDrawingCacheEnabled = webView.isDrawingCacheEnabled();
  webView.setDrawingCacheEnabled(true);
  // copy to a new bitmap, otherwise the bitmap will be
  // destroyed when the drawing cache is destroyed
  // webView.getDrawingCache can return null if drawing cache is disabled or if the size is 0
  Bitmap bitmap = webView.getDrawingCache();
  Bitmap newBitmap = null;
  if (bitmap != null) {
   newBitmap = bitmap.copy(Bitmap.Config.RGB_565, false);
  }

  webView.destroyDrawingCache();
  webView.setDrawingCacheEnabled(isDrawingCacheEnabled);

  listener.onSnapshotReady(newBitmap);
 }
}

Sry replace the function with this code

public File getBitmapFromwebchartView(WebView view2) {
    if (view2 != null) {
      view2.setDrawingCacheEnabled(true);
      Bitmap b = view2.getDrawingCache();
      if (b != null) {

        try {

          fl = new File(Environment.getExternalStorageDirectory(),
              "Realitycheck" + ".jpg");

          // write the bytes in file
          FileOutputStream fo;

          fo = new FileOutputStream(fl);

          b.compress(CompressFormat.JPEG, 95, fo);
        } catch (Exception e) {
          e.printStackTrace();
        }
      }
    }
    return fl;
  }

代码示例来源：origin: stackoverflow.com

public File getBitmapFromwebchartView(WebView view2) {

  File fi;

  if (view2 != null) {
    view2.setDrawingCacheEnabled(true);
    Bitmap b = view2.getDrawingCache();
    if (b != null) {

      try {

        fi = new File(Environment.getExternalStorageDirectory(), "Screenshot" + ".jpg");
        //fi     = new File(Environment.getExternalStorageDirectory(),"Realitycheck" + ".jpg");

        // write the bytes in file
        FileOutputStream fo;

        fo = new FileOutputStream(fi);

        b.compress(CompressFormat.JPEG, 95, fo);
      } catch (Exception e) {
        e.printStackTrace();
      }
    }
  }
  return fi;

Use this Code to get the screen shot of web view

public File getBitmapFromwebchartView(WebView view2) {
    if (view2 != null) {
      view2.setDrawingCacheEnabled(true);
      Bitmap b = view2.getDrawingCache();
      if (b != null) {

        try {

          fl = new File(Environment.getExternalStorageDirectory(),
              "Realitycheck" + ".jpg");

          // write the bytes in file
          FileOutputStream fo;

          fo = new FileOutputStream(fl);

          newbitmap.compress(CompressFormat.JPEG, 95, fo);
        } catch (Exception e) {
          e.printStackTrace();
        }
      }
    }
    return fl;
  }
