Android 监听手机GPS打开状态实现代码

GPS_Presenter

package com.yiba.core;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.location.LocationManager;

/**
* Created by ${zhaoyanjun} on 2017/3/29.
* GPS 开关监听
*/

public class GPS_Presenter {
 private Context mContext ;
 private Receiver receiver ;
 private GPS_Interface mInterface ;
 private String GPS_ACTION = "android.location.PROVIDERS_CHANGED" ;

public GPS_Presenter(Context context , GPS_Interface mInterface ){
   this.mContext = context ;
   this.mInterface = mInterface ;

observeWifiSwitch();
 }

private void observeWifiSwitch(){
   IntentFilter filter = new IntentFilter();
   filter.addAction( GPS_ACTION );
   receiver = new Receiver() ;
   mContext.registerReceiver(receiver, filter);
 }

/**
  * 释放资源
  */
 public void onDestroy(){
   if ( receiver != null ){
     mContext.unregisterReceiver( receiver );
   }
   if (mContext!=null){
     mContext = null;
   }
 }

class Receiver extends BroadcastReceiver {

@Override
   public void onReceive(Context context, Intent intent) {
     if (intent.getAction().matches( GPS_ACTION )) {
        if ( mInterface != null ){
          mInterface.gpsSwitchState( gpsIsOpen( context ));
        }
     }
   }
 }

/**
  * 判断GPS是否开启，GPS或者AGPS开启一个就认为是开启的
  * @param context
  * @return true 表示开启
  */
 public boolean gpsIsOpen(final Context context) {
   LocationManager locationManager
       = (LocationManager) context.getApplicationContext().getSystemService(Context.LOCATION_SERVICE);
   // 通过GPS卫星定位，定位级别可以精确到街（通过24颗卫星定位，在室外和空旷的地方定位准确、速度快）
   boolean gps = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
   // 通过WLAN或移动网络(3G/2G)确定的位置（也称作AGPS，辅助GPS定位。主要用于在室内或遮盖物（建筑群或茂密的深林等）密集的地方定位）
   boolean network = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
   if (gps || network) {
     return true;
   }

return false;
 }
}

GPS_Interface 回调接口

package com.yiba.core;

/**
* Created by ${zhaoyanjun} on 2017/3/29.
* gps 开关监听
*/

public interface GPS_Interface {
 void gpsSwitchState( boolean gpsOpen );
}

在 Activity 中使用

package com.yiba.core;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity implements GPS_Interface {

private GPS_Presenter gps_presenter ;

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

gps_presenter = new GPS_Presenter( this , this ) ;

}

@Override
 protected void onDestroy() {
   super.onDestroy();

//释放资源
   if ( gps_presenter != null ){
     gps_presenter.onDestroy();
   }
 }

@Override
 public void gpsSwitchState(boolean gpsOpen) {
   if ( gpsOpen ){
     Toast.makeText(this, " 手机GPS 打开", Toast.LENGTH_SHORT).show();
   }else {
     Toast.makeText(this, " 手机GPS 关闭", Toast.LENGTH_SHORT).show();
   }
 }
}
