Question

我创建了一个在WebView上启动网站的Activity，我添加了一些缩放支持和缩放控件。我的问题：当我想从网站缩放左侧部分时，通过使用捏缩放或控制，总是显示右侧而不是左侧，当我想要左侧scrool时，webview是“被阻止”我的意思是它只显示右侧就是它。我希望你理解我！这是我使用的代码：

mWebView = (WebView) findViewById(R.id.webview);

        mWebView.getSettings().setBuiltInZoomControls(true);
        mWebView.getSettings().setSupportZoom(true);

        mWebView.setInitialScale(65);
        mWebView.setWebChromeClient(new WebChromeClient() {
            public void onProgressChanged(WebView view, int progress)   
            {
             //Make the bar disappear after URL is loaded, and changes string to Loading...
            MyActivity.setTitle("Loading...");
             MyActivity.setProgress(progress * 100); //Make the bar disappear after URL is loaded

             // Return the app name after finish loading
                if(progress == 100)
                   MyActivity.setTitle(R.string.app_name);
              }
            });
        mWebView.setWebViewClient(new Manipulation());
        mWebView.getSettings().setJavaScriptEnabled(true);

        mWebView.loadUrl("myURL");

请问如何解决缩放问题？

Answer 1

    public class WebViewHelp extends Activity {
//specify url to open
    String url="";
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Uri uri=Uri.parse(url);
        Intent i=new Intent(Intent.ACTION_VIEW,uri);
        startActivity(i);
    }

   //xml file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"

  <WebView
    android:id="@+id/webView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
  />
</LinearLayout>


//Activity
 public class Main extends Activity {
//specify the url to open
String url="";
  private WebView myWebView;
  private static final FrameLayout.LayoutParams ZOOM_PARAMS =
new FrameLayout.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT,
Gravity.BOTTOM);

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.setContentView(R.layout.webview);
    this.myWebView = (WebView) this.findViewById(R.id.webView);

    FrameLayout mContentView = (FrameLayout) getWindow().
    getDecorView().findViewById(android.R.id.content);
    final View zoom = this.myWebView.getZoomControls();
    mContentView.addView(zoom, ZOOM_PARAMS);
    zoom.setVisibility(View.GONE);

    this.myWebView.loadUrl(url);
  }
}
