谷歌地图没有显示

Question

在我的应用程序中，当我打开谷歌链接时，我将使用谷歌导航

这是我的代码：

public class FullscreenActivity extends Activity {
private WebView webView;
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_fullscreen);
    webView = (WebView) findViewById(R.id.webView);
    webView.setWebViewClient(new myWebClient());
    webView.loadUrl("http://www.mywebsite.nl/");
    webView.setVerticalScrollBarEnabled(false);
    WebSettings webSettings = webView.getSettings();
    webSettings.setJavaScriptEnabled(true);
}

public class myWebClient extends WebViewClient
{
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
    // TODO Auto-generated method stub
    super.onPageStarted(view, url, favicon);
}
@Override
 public boolean shouldOverrideUrlLoading(WebView view, String url) {
 if (url.startsWith("tel:")) { 
         Intent intent = new Intent(Intent.ACTION_DIAL,
                 Uri.parse(url)); 
         startActivity(intent); 
 }else if(url.startsWith("http:") || url.startsWith("https:")) {
     view.loadUrl(url);
 }
 return true;
    }
}
    public static void maps(Activity activity, String address) {
   try {
    Intent intent = new Intent(Intent.ACTION_VIEW,         Uri.parse("http://maps.google.com/maps?q=" + address));
    activity.startActivity(intent);
} catch (ActivityNotFoundException e) {
    Toast.makeText(activity, activity.getString(R.id.webView), Toast.LENGTH_SHORT).show();
}
public static void navigation(Activity activity, String address) {
try {
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("google.navigation:q=" + address));
    activity.startActivity(intent);
} catch (ActivityNotFoundException e) {
    Toast.makeText(activity, activity.getString(R.id.webView), Toast.LENGTH_SHORT).show();
}
 }
public boolean onKeyDown(int keyCode, KeyEvent event)
{
    if ((keyCode == KeyEvent.KEYCODE_BACK) && webView.canGoBack()) {
        webView.goBack();
        return true;
    }
    return super.onKeyDown(keyCode, event);
}
   }

我忘了什么吗？当我点击谷歌时。导航？q=鹿特丹，它什么都不做。我希望任何人都能帮助我。

您应该在清单中添加密钥：

<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="xxxxxxxxxxxxxxxxxxxx"/>

并添加权限

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
