Android webview 适合所有内容到屏幕上

Question

您好，我有一个 webview，我希望它适合屏幕，这样用户就不必水平或垂直滚动​​

我之前搜索过，很多人建议以下但它只限制宽度，用户仍然需要垂直滚动：

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

我尝试了另一种方法，使用缩放方法，但它不起作用.....我得到了窗口宽度（1024 像素），网页内容宽度也是 1024 像素！！所以缩放不起作用....有什么方法可以得到正确的缩放？

或者....还有其他方法吗？....谢谢！！

// 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);

只是一些注释：

缩放网页视图：

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

获取窗口宽度和高度：

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

Answer 1

使用以下方法。

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

Answer 2

要使 webview 扩展到整个屏幕，请在活动布局 xml 中添加 webview，并确保将 layout_width 和 layout_height 设置为 fill_parent。这是一个简单的例子：

  <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>
