Improve this questionDoes anyone know how to convert html code (with images within it) to image on Android? I know how to make it on Java using JLabel/JEditorPane and BufferedImage, but now should make the same with Android.
The answer of @Neo1975 is worked for me, but to avoid using deprecated method WebView.capturePicture() you could use the following method to capture content of WebView.
/**
* WevView screenshot
*
* @param webView
* @return
*/
private static Bitmap screenshot(WebView webView) {
webView.measure(View.MeasureSpec.makeMeasureSpec(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED),View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
webView.layout(0, 0, webView.getMeasuredWidth(),
webView.getMeasuredHeight());
webView.setDrawingCacheEnabled(true);
webView.buildDrawingCache();
Bitmap bitmap = Bitmap.createBitmap(webView.getMeasuredWidth(),
webView.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
Paint paint = new Paint();
int iHeight = bitmap.getHeight();
canvas.drawBitmap(bitmap, 0, iHeight, paint);
webView.draw(canvas);
return bitmap;
}
The idea behind it is using WebView.draw(Canvas) method.
For this task I use the follow trick: I used a webview to parse HTML and call the method capturePicture on WevView object to extract a Picture of HTML, so I can suggest you the follow sniplet:
WebView wv = new WebView(this);
wv.loadData("<html><body><p>Hello World</p></body></html>");
Picture p = wv.capturePicture();
I hope this can help, but if you foun a different way to solve it please post it.
