使用意圖(Intent)啟動 Android 內建谷歌地圖的街景(StreetView)

啟動 Android 內建谷歌地圖的街景(StreetView), 可以使用:
"google.streetview:cbll=<lat>,<lon>

package com.AndroidIntentGoogleMaps;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class AndroidIntentGoogleMaps extends Activity {
 
 EditText inputLatitude, inputLongitude;
 Button buttonStartMaps;
 
 final static float DEFAULT_Latitude = (float) 40.75773;
 final static float DEFAULT_Longitude = (float) -73.985708;
 
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        inputLatitude = (EditText)findViewById(R.id.Latitude);
        inputLongitude = (EditText)findViewById(R.id.Longitude);
     buttonStartMaps = (Button)findViewById(R.id.startmaps);
     
     inputLatitude.setText(String.valueOf(DEFAULT_Latitude));
     inputLongitude.setText(String.valueOf(DEFAULT_Longitude));
     
     buttonStartMaps.setOnClickListener(new Button.OnClickListener(){

   @Override
   public void onClick(View arg0) {
    // TODO Auto-generated method stub
    String lat = inputLatitude.getText().toString();
    String lon = inputLongitude.getText().toString();

    String strUri = "google.streetview:cbll="+lat+","+lon;
    
    Toast.makeText(AndroidIntentGoogleMaps.this, strUri, Toast.LENGTH_LONG).show();

    Intent intent = new Intent(android.content.Intent.ACTION_VIEW, Uri.parse(strUri));
    startActivity(intent);
   }});
     
    }
}
