代码如下：

AndroidManifest.xml:

在</application>后面增加一行：

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

Activity_main.xml:

    <Button

       android:id="@+id/locationButtonId"

       android:layout_width="fill_parent"

       android:layout_height="wrap_content"

        android:text="绑定监听器"/>

MainActivity.java:

package leihu.location01;

import android.location.Location;

import android.location.LocationListener;

import android.location.LocationManager;

       button = (Button)findViewById(R.id.locationButtonId);

       button.setOnClickListener(new ButtonListener());

    }

    private class ButtonListener implements OnClickListener{

           //得到LocationManager对象

           LocationManager locationManager = (LocationManager)MainActivity.this.getSystemService(Context.LOCATION_SERVICE);

           //1.定义当前所使用的Location Provider     locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,0,0,newTestLocationListener());

       }

    }

    private class TestLocationListener implements LocationListener{
