Comment imprimer WebView entier (Scrollable)?

Question

Je veux imprimer le tout WebView sur Button Click.

J'ai utilisé l'imprimante Citizen. J'ai essayé ci-dessous.

private Bitmap CitizenWebPrint(WebView webView) { 
    Bitmap bitmapCitizen = null; 
    Picture capturePicture = webView.capturePicture(); 
    int width = capturePicture.getWidth(); 
    int height = capturePicture.getHeight(); 

    try { 
     bitmapCitizen = Bitmap.createBitmap(width, height, Bitmap.Config.RGB_565); 
    } catch (OutOfMemoryError e) { 
     Toast.makeText(getApplicationContext(),"2",Toast.LENGTH_LONG).show(); 
    } 
    capturePicture.draw(new Canvas(bitmapCitizen)); 

    return bitmapCitizen; 
} 

Mais le problème est, Cela peut imprimer seulement une partie visible de WebView.

Comment imprimer tout le WebView? Dessinez l'objet DecorView de la fenêtre en cours, puis dessinez l'objet Bitmap.

Answer 1

Et vous pouvez faire comme ça.

Avant de le faire, vous pouvez le faire.

WebSettings webSettings = webView.getSettings(); 
    webSettings.setJavaScriptEnabled(true); 
    webSettings.setSupportZoom(true); 
    webView.requestFocusFromTouch(); 
    webView.setWebViewClient(new WebViewClient() { 
     @Override 
     public boolean shouldOverrideUrlLoading(WebView view, String url) { 
      view.loadUrl(url); 
      return true; 
     } 
    }); 
    webView.loadUrl("your url"); 

Et vérifiez la version.

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    checkSdkVersion(); 
    setContentView(R.layout.activity_webview_capture); 
} 

// check version 
private void checkSdkVersion() { 
    if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.LOLLIPOP) { 
     WebView.enableSlowWholeDocumentDraw(); 
    } 
}

Way 1

private void getScreenshot() { 
    float scale = webView.getScale(); 
    int webViewHeight = (int) (webView.getContentHeight() * scale + 0.5); 
    Bitmap bitmap = Bitmap.createBitmap(webView.getWidth(), webViewHeight, Bitmap.Config.ARGB_8888); 
    Canvas canvas = new Canvas(bitmap); 
    webView.draw(canvas); 
    // save to the File 
    try { 
     String fileName = Environment.getExternalStorageDirectory().getPath() + "/webview_capture1.jpg"; 
     FileOutputStream fos = new FileOutputStream(fileName); 
     // Save 
     bitmap.compress(Bitmap.CompressFormat.JPEG, 70, fos); 
     fos.close(); 
     Toast.makeText(WebviewFromDraw.this, "Screenshot OK", Toast.LENGTH_LONG).show(); 
     bitmap.recycle(); 
    } catch (Exception e) { 
     e.getMessage(); 
    } 
} 

Way 2 utilisation

private void getScreenshot() { 

    bitmap = webView.getDrawingCache(); 
    try { 
     String fileName = Environment.getExternalStorageDirectory().getPath()+"/webview_capture2.jpg"; 
     FileOutputStream fos = new FileOutputStream(fileName); 
     bitmap.compress(Bitmap.CompressFormat.JPEG, 70, fos); 
     fos.close(); 
     Toast.makeText(WebviewFromDrawCache.this, "Screenshot OK", Toast.LENGTH_LONG).show(); 

    } catch (Exception e) { 
     Log.e("TAG", e.getMessage()); 
    } 
} 

@Override 
protected void onDestroy() { 
    super.onDestroy(); 
    //recycle 
    if(bitmap!=null) { 
     bitmap.recycle(); 
    } 
} 

Way 3 même à la vôtre, il fonctionne bien dans mon appareil.

private void getScreenshot() { 
    Picture picture = webView.capturePicture(); 
    int width = picture.getWidth(); 
    int height = picture.getHeight(); 
    if (width > 0 && height > 0) { 
     Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888); 
     Canvas canvas = new Canvas(bitmap); 
     picture.draw(canvas); 
     try { 
      String fileName = Environment.getExternalStorageDirectory().getPath()+"/webview_capture3.jpg"; 
      FileOutputStream fos = new FileOutputStream(fileName); 
      bitmap.compress(Bitmap.CompressFormat.JPEG, 70, fos); 
      fos.close(); 
      Toast.makeText(WebviewFromCapture.this, "Screenshot ok", Toast.LENGTH_LONG).show(); 
      bitmap.recycle(); 
     } catch (Exception e) { 
      Log.e(TAG, e.getMessage()); 
     } 
    } 
}
