您好我有一個網頁視圖,我希望它適合屏幕,使得用戶不必之前滾動水平或垂直的Android的WebView適合所有的內容篩選

我已搜查,許多建議以下,但它只限制了寬度,用戶仍然有垂直滾動:

engine = (WebView) (findViewById(R.id.webView1)); 
engine.loadUrl(www.example.com); 
engine.getSettings().setLoadWithOverviewMode(true); 
engine.getSettings().setUseWideViewPort(true); 

我嘗試另一種方法,使用縮放方法,但它不會工作.....我得到的窗口寬度(1024個像素)而網頁內容的寬度也是1024像素!所以縮放不起作用....是否有任何方法來獲得正確的比例?

或....還有其他方法嗎?......謝謝!

// get the window width and height 
    Point outSize = new Point(); 
    getWindowManager().getDefaultDisplay().getSize(outSize); 
    width = outSize.x; 
    height = outSize.y; 
    Log.i("Menuboard", "width: " + Integer.toString(width) + ", height: " 
      + Integer.toString(height)); 

WebViewClient client = new WebViewClient() { 

     public void onPageFinished(WebView view, String url) { 
      int x = engine.getWidth(); 
      int y = engine.getHeight(); 

      Log.i("Menuboard", "web width: " + Integer.toString(x) 
        + ", height: " + Integer.toString(y)); 

      int scale1 = width * 100/x; 
      int scale2 = height * 100/y; 

      Log.i("Menuboard", "Scale1: " + Integer.toString(scale1) 
        + ", Scale2: " + Integer.toString(scale2)); 

      if (scale1 < scale2) { 
       engine.setInitialScale(scale1); 
       Log.i("Menuboard", "scale1"); 
      } else if (scale1 > scale2) { 
       engine.setInitialScale(scale2); 
       Log.i("Menuboard", "scale2: " + Integer.toString(scale2)); 
      } 
     } 
    }; 

    engine = (WebView) (findViewById(R.id.webView1)); 
    engine.loadUrl(string); 
    engine.getSettings().setBuiltInZoomControls(true); 
    engine.setPadding(0, 0, 0, 0); 
      engine.setWebViewClient(client); 

只是一些注意事項:

要縮放網頁視圖:

engine = (WebView) (findViewById(R.id.webView1)); 
engine.loadUrl(www.example.com); 
engine.getSettings().setBuiltInZoomControls(true); 
engine.setPadding(0, 0, 0, 0); 
engine.setInitialScale(50); // 0 - 100 where 100 is full scale 

爲了得到窗口的寬度和高度:

Point outSize = new Point(); 
getWindowManager().getDefaultDisplay().getSize(outSize); 
width = outSize.x; 
height = outSize.y; 
+0

爲了使web視圖擴展到整個屏幕,請將webview添加到您的活動佈局xml中,並確保您設置了layout_widthlayout_heightfill_parent。下面是一個簡單的例子:

<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"> 
    <WebView 
     android:id="@+id/webview" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent"/> 
    </LinearLayout>

使用以下方法。

webview.getSettings().setUseWideViewPort(true); 
webview.getSettings().setLoadWithOverviewMode(true);
