如何在webview android中显示谷歌地图导航网址

Question

我需要在webview中加载以下代码。

   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？

这会将网址加载到您的网页视图：

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");

修改

以下是使用上述代码的一些截图。网络视图中的Google地图导航：

修改

的活动：

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>

清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.webview"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="19" />

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

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.webview.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>
