这是它们

xml

<WebView
  android:id="@+id/web_view"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"      
  android:layout_weight="1.0" />

类

    WebView webview = (WebView) findViewById(R.id.web_view);
    webview.getSettings().setSupportZoom(true);
    webview.getSettings().setBuiltInZoomControls(true);
    webview.loadUrl("file:///android_asset/yourHtmlFile.html");
