自己新建一个项目弄弄吧：

    activity：

public class School_ggtz extends Activity {
	private WebView webView;
	private String url;
	private ImageView iv_school_title;
	private TextView tv_school_content;
	private ProgressDialog dialog;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_school_xxgk);
		iv_school_title = (ImageView) findViewById(R.id.iv_school_title);
		iv_school_title.setOnClickListener(new View.OnClickListener() {

			@Override
			public void onClick(View arg0) {
				finish();
			}
		});
		tv_school_content = (TextView) findViewById(R.id.tv_school_content);
		tv_school_content.setText(getResources().getString(
				R.string.school_ggtz_content));
		webView = (WebView) findViewById(R.id.id_webview);
		url = getResources().getString(R.string.school_ggtz);
		webView.loadUrl(url);
		webView.setWebViewClient(new WebViewClient() {
			@Override
			public boolean shouldOverrideUrlLoading(WebView view, String url) {
				view.loadUrl(url);
				return true;
			}
		});
		WebSettings settings = webView.getSettings();
		settings.setSupportZoom(true);
		settings.setBuiltInZoomControls(true);
		settings.setDisplayZoomControls(false); // 隐藏webview缩放按钮
		settings.setUseWideViewPort(true);
		settings.setLoadWithOverviewMode(true);
		settings.setJavaScriptEnabled(true);
		settings.setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
		webView.setWebChromeClient(new WebChromeClient() {

			@Override
			public void onProgressChanged(WebView view, int newProgress) {
				// TODO Auto-generated method stub
				// newProgress 1-100之间的整数
				if (newProgress == 100) {
					// 网页加载完毕，关闭ProgressDialog
					closeDialog();
				} else {
					// 网页正在加载,打开ProgressDialog
					openDialog(newProgress);
				}
			}

			private void closeDialog() {
				// TODO Auto-generated method stub
				if (dialog != null && dialog.isShowing()) {
					dialog.dismiss();
					dialog = null;
				}
			}

			private void openDialog(int newProgress) {
				// TODO Auto-generated method stub
				if (dialog == null) {
					dialog = new ProgressDialog(School_ggtz.this);
					dialog.setTitle("正在加载");
					dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
					dialog.setProgress(newProgress);
					dialog.show();

				} else {
					dialog.setProgress(newProgress);
				}

			}
		});
	}
}

    xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white"
    android:orientation="vertical" >

    <include layout="@layout/activity_school_title" />

    <WebView
        android:id="@+id/id_webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="none" />

</LinearLayout>

    效果图：PS：可以缩放，并且支持双击Max，支持脚本。
