Android - 如何在點擊時抓取網頁視圖的快照

Question

我想將網頁截圖截圖到SD卡。

我使用下列獲得網頁中的WebView

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    mService = new BluetoothService(this, mHandler); 
    setContentView(R.layout.main); 
    web = (WebView) findViewById(R.id.webView1); 
    setUpWebView(); 
    web.loadUrl("http://www.domain.com"); 
} 

我想在這裏把快照代碼在下面的點擊功能。

class ClickEvent implements View.OnClickListener { 
    public void onClick(View v) { 
     ??????????????????????? 
    }} 

請幫助我，我從最後兩天不同的代碼嘗試，但沒有運氣

特林我嘗試下面的代碼提示，但這逼搶應用。

w = new WebView(this); 
    w.setWebViewClient(new WebViewClient() 
    { 
     public void onPageFinished(WebView view, String url) 
     { 
       Picture picture = view.capturePicture(); 
       Bitmap b = Bitmap.createBitmap(picture.getWidth(), 
       picture.getHeight(), Bitmap.Config.ARGB_8888); 
       Canvas c = new Canvas(b); 

       picture.draw(c); 
       FileOutputStream fos = null; 
       try { 

        fos = new FileOutputStream("mnt/sdcard/yahoo.jpg"); 
         if (fos != null) 
         { 
          b.compress(Bitmap.CompressFormat.JPEG, 100, fos); 

          fos.close(); 
         } 
        } 
       catch(Exception e) 
       { 

       } 
     } 
    }); 

setContentView(w); 
w.loadUrl("http://search.yahoo.com/search?p=android"); 
} 
@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
getMenuInflater().inflate(R.menu.activity_main, menu); 
return true; 
}} 

感謝您的幫助。

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; 
    }

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; 
    } 
Use this code and get the required file stored in sdcard.

File file; 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    mService = new BluetoothService(this, mHandler); 
    setContentView(R.layout.main); 
    web = (WebView) findViewById(R.id.webView1); 
    setUpWebView(); 
    web.loadUrl("http://www.domain.com"); 
} 
class ClickEvent implements View.OnClickListener { 
    public void onClick(View v) { 
    file= getBitmapFromwebchartView(web); 
    }} 
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; 
    }
