android 监听wifi的开关状态实现代码
wifiswitch_presenter 源码:
package com.yiba.wifi.sdk.lib.presenter; import android.content.broadcastreceiver; import android.content.context; import android.content.intent; import android.content.intentfilter; import android.net.wifi.wifimanager; /** * created by ${zhaoyanjun} on 2017/3/29. * wifi 开关监听 */ public class wifiswitch_presenter { private context mcontext ; private receiver receiver ; private wifiswitch_interface minterface ; public wifiswitch_presenter( context context , wifiswitch_interface minterface ){ this.mcontext = context ; this.minterface = minterface ; observewifiswitch(); } private void observewifiswitch(){ intentfilter filter = new intentfilter(); filter.addaction(wifimanager.wifi_state_changed_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) { int wifistate = intent.getintextra(wifimanager.extra_wifi_state, 0); switch (wifistate) { case wifimanager.wifi_state_disabled: if (minterface != null){ minterface.wifiswitchstate(wifiswitch_interface.wifi_state_disabled); } break; case wifimanager.wifi_state_disabling: if (minterface != null){ minterface.wifiswitchstate(wifiswitch_interface.wifi_state_disabling); } break; case wifimanager.wifi_state_enabled: if (minterface != null){ minterface.wifiswitchstate(wifiswitch_interface.wifi_state_enabled); } break; case wifimanager.wifi_state_enabling: if ( minterface != null ) { minterface.wifiswitchstate(wifiswitch_interface.wifi_state_enabling); } break; case wifimanager.wifi_state_unknown: if ( minterface != null ){ minterface.wifiswitchstate( wifiswitch_interface.wifi_state_unknown ); } break; } } } }
wifiswitch_interface 源码
package com.yiba.wifi.sdk.lib.presenter; /** * created by ${zhaoyanjun} on 2017/3/29. * wifi 开关监听 */ public interface wifiswitch_interface { int wifi_state_enabling = 0 ; int wifi_state_enabled = 1 ; int wifi_state_disabling = 2 ; int wifi_state_disabled = 3 ; int wifi_state_unknown = 4 ; void wifiswitchstate( int state ); }
使用方式 mainactivity :
package com.yiba.core; import android.os.bundle; import android.support.v7.app.appcompatactivity; import android.widget.toast; public class mainactivity extends appcompatactivity implements wifiswitch_interface { private wifiswitch_presenter wifiswitch_presenter ; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); wifiswitch_presenter = new wifiswitch_presenter( this , this ) ; } @override public void wifiswitchstate(int state) { switch ( state ){ case wifiswitch_interface.wifi_state_disabled : toast.maketext(this, "wifi 已经关闭", toast.length_short).show(); break; case wifiswitch_interface.wifi_state_disabling: toast.maketext(this, "wifi 正在关闭", toast.length_short).show(); break; case wifiswitch_interface.wifi_state_enabled : toast.maketext(this, "wifi 已经打开", toast.length_short).show(); break; case wifiswitch_interface.wifi_state_enabling : toast.maketext(this, "wifi 正在打开", toast.length_short).show(); break; } } @override protected void ondestroy() { super.ondestroy(); //释放资源 if ( wifiswitch_presenter != null ){ wifiswitch_presenter.ondestroy(); } } }
