copied!<p>You could use a custom <a href="http://developer.android.com/reference/android/webkit/WebViewClient.html" rel="nofollow"><code>WebViewClient</code></a> and implement the <code>shouldOverrideUrlLoading()</code> method to handle a click on your images in the activity. There, you can download the image and set it as a wallpaper.</p> <p>Here is an example for such a <code>WebViewClient</code>:</p> <pre><code>public class MyWebViewClient extends WebViewClient { private WallpaperManager mWallpaperManager; private Context mContext; public MyWebViewClient(Context context) { mContext = context; mWallpaperManager = WallpaperManager.getInstance(context); } @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { if (url.endsWith(".png") || url.endsWith(".jpg") || url.endsWith(".jpeg")) { new AsyncTask<String, Void, Bitmap>() { @Override protected Bitmap doInBackground(String... params) { try { return downloadImage(params[0]); } catch (IOException e) { e.printStackTrace(); } return null; } @Override protected void onPostExecute(Bitmap result) { if (result != null) { try { mWallpaperManager.setBitmap(result); Toast.makeText(mContext, "Done!!", Toast.LENGTH_SHORT).show(); } catch (IOException e) { e.printStackTrace(); } } } }.execute(url); return true; } return false; } private Bitmap downloadImage(String fileUrl) throws IOException { try { HttpGet httpRequest = new HttpGet(new URL(fileUrl).toURI()); HttpClient httpClient = new DefaultHttpClient(); HttpResponse response = (HttpResponse) httpClient.execute(httpRequest); BufferedHttpEntity buffer = new BufferedHttpEntity(response.getEntity()); return BitmapFactory.decodeStream(buffer.getContent()); } catch (IllegalArgumentException e) { e.printStackTrace(); } catch (URISyntaxException e) { e.printStackTrace(); } return null; } } </code></pre> <p>You add the WebViewClient to your WebView via <code>setWebClient(new MyWebViewClient(this))</code> in your activity.</p>
