如何在webview中显示谷歌地图导航地址android

Question

我需要下面的代码在webview中加载。

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); 

我该怎么做？

这将URL加载到您的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");

活动：

package com.example.webview; 

import android.app.Activity; 
import android.os.Bundle; 
import android.view.Menu; 
import android.webkit.WebView; 
import android.webkit.WebViewClient; 

public class MainActivity extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     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; 
    } 
} 

布局：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
tools:context="com.example.webview.MainActivity$PlaceholderFragment" > 

    <WebView 
     android:id="@+id/webView1" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentTop="true" /> 

</RelativeLayout>
