解决方案
这会将URL加载到webview中：
WebView webview =（WebView）findViewById （R.id.webView1）;
webview.setWebViewClient（新的WebViewClient（））;
webview.getSettings（）。setJavaScriptEnabled（true）;
webview.loadUrl（http://maps.google.com/maps？+saddr = 43.0054446，-87.9678884+& daddr = 42.9257104，-88.0508355）;

}
@Override
public boolean onCreateOptionsMenu（菜单菜单）{
//膨胀菜单;这会将项目添加到操作栏（如果存在）。
getMenuInflater（）。inflate（R.menu.main，menu）;
返回true;

I need the following code to load in webview.
final Intent intent = new Intent(Intent.ACTION_VIEW,
Uri.parse(
"http://maps.google.com/maps?" +
"saddr=43.0054446,-87.9678884" +
"&daddr=42.9257104,-88.0508355"));
intent.setClassName(
"com.google.android.apps.maps",
"com.google.android.maps.MapsActivity");
startActivity(intent);
How do I do this?
解决方案 This will load the URL to your webview:
WebView webview = (WebView) findViewById(R.id.webView1);
webview.setWebViewClient(new WebViewClient());
webview.getSettings().setJavaScriptEnabled(true);
webview.loadUrl("http://maps.google.com/maps?" + "saddr=43.0054446,-87.9678884" + "&daddr=42.9257104,-88.0508355");

}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
