Question

以下代码用于在我的Android应用上打开网页。我想在webview上打开市场：//链接。我尝试了一些在这里讨论的例子。但没跟我合作。如何允许以market：//开头的所有链接在点按时自动打开Google Play商店？

package my.webview.test.com.fragment;

import android.webkit.WebViewClient;
import android.widget.Button;
import android.webkit.DownloadListener;


public class WebFragment extends Fragment {
//Constant
private static final String TAG = "WebFragment";
// Member variables
private String mUrl;
private boolean mIsLoadFinish = false;

// View Member Variables
private WebView mWebView;
private WebViewClient mWebViewClient;
private Button mBtnBack;
private Button mBtnForward;
private Button mBtnRefresh;

@

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_web, null);

    // Init WebView
    initWebView(view);

    return view;
}

@
Override
public void onResume() {
    super.onResume();
    mWebView.loadUrl(mUrl);
    enableControllerButton();

    mWebView.setDownloadListener(new DownloadListener() {

        String contentDisposition, String mimetype,

            i.setData(Uri.parse(url));
            startActivity(i);
        }
    });
}



// Property access
public void setUrl(String url) {
    mUrl = url;
}

    webView.setWebViewClient(new WebViewClient()
    {

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url)
        { 
            if (url.contains("market://"))
            {
                    try
                    {
                        view.getContext().startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
                    } catch (android.content.ActivityNotFoundException e)
                    {
                        e.printStackTrace();
                    }
                    return true;
            }
            return super.shouldOverrideUrlLoading(view, url);
        }
    });
    webView.loadUrl(url);
