Welche capturePicture Funktion ersetzen kann

Question

Ich habe eine Frage. Zu diesem Zeitpunkt ist capturePicture von WebView veraltet.

Ich möchte fragen, ob es eine Möglichkeit gibt, die Funktion zu ersetzen. Ich meinte, es kann Capture gesamte von dem Webansicht (nicht nur die Ansicht angezeigt wird)

Dank

Answer 1

Ich fand schließlich die Lösung aus.

Einige Codes

public class WebViewActivity extends Activity { 

    private static WebView webView; 

    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.webview); 

     webView = (WebView) findViewById(R.id.webView1); 
     webView.loadUrl("http://developer.android.com/reference/packages.html"); 
//  webView.loadUrl("http://developer.android.com/training/basics/firstapp/creating-project.html"); 

     webView.setWebViewClient(new WebViewClient() { 

      public void onPageFinished(WebView view, String url) { 
       // do your stuff here 
       webView.measure(MeasureSpec.makeMeasureSpec(
         MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED), 
         MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED)); 
       webView.layout(0, 0, webView.getMeasuredWidth(), 
         webView.getMeasuredHeight()); 
       webView.setDrawingCacheEnabled(true); 
       webView.buildDrawingCache(); 
       Bitmap bm = Bitmap.createBitmap(webView.getMeasuredWidth(), 
         webView.getMeasuredHeight(), Bitmap.Config.ARGB_8888); 

       Canvas bigcanvas = new Canvas(bm); 
       Paint paint = new Paint(); 
       int iHeight = bm.getHeight(); 
       bigcanvas.drawBitmap(bm, 0, iHeight, paint); 
       webView.draw(bigcanvas); 
       System.out.println("1111111111111111111111=" 
         + bigcanvas.getWidth()); 
       System.out.println("22222222222222222222222=" 
         + bigcanvas.getHeight()); 

       if (bm != null) { 
        try { 
         String path = Environment.getExternalStorageDirectory() 
           .toString(); 
         OutputStream fOut = null; 
         File file = new File(path, "/aaaa.png"); 
         fOut = new FileOutputStream(file); 

         bm.compress(Bitmap.CompressFormat.PNG, 50, fOut); 
         fOut.flush(); 
         fOut.close(); 
         bm.recycle(); 
        } catch (Exception e) { 
         e.printStackTrace(); 
        } 
       } 
      } 
     }); 
    } 
} 

Die layout.xml

<?xml version="1.0" encoding="utf-8"?> 
<WebView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/webView1" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
/> 

Answer 2

Verwendung draw() Methode der WebView

Beispiel:

ImageView imageview; 
WebView webview; 
class Background extends AsyncTask<Void, Void, Bitmap> 
{ 
    @Override 
    protected Bitmap doInBackground(Void... params) 
    { 
     try 
     { 
      Thread.sleep(2000); 
      Bitmap bitmap = Bitmap.createBitmap(webview.getWidth(), webview.getHeight(), Config.ARGB_8888); 
      Canvas canvas = new Canvas(bitmap); 
      webview.draw(canvas); 
      return bitmap; 
     } 
     catch (InterruptedException e){} 
     catch (Exception e){} 
     return null; 
    } 
    @Override 
    protected void onPostExecute(Bitmap result) 
    { 
     imageview.setImageBitmap(result); 
    } 
} 


webview.setWebChromeClient(new WebChromeClient() 
{ 
    public void onProgressChanged(WebView view, int progress) 
    { 
     if(progress==100) 
      new Background().execute(); 
    } 
});
