WifiSwitch_Interface源码
packagecom.yiba.wifi.sdk.lib.presenter;

使用方式MainActivity：
packagecom.yiba.core;
importandroid.os.Bundle;
importandroid.support.v7.app.AppCompatActivity;
importandroid.widget.Toast;
publicclassMainActivityextendsAppCompatActivityimplementsWifiSwitch_Interface{
privateWifiSwitch_PresenterwifiSwitch_presenter;
@Override
protectedvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
wifiSwitch_presenter=newWifiSwitch_Presenter(this,this);
}
@Override
publicvoidwifiSwitchState(intstate){
switch(state){
caseWifiSwitch_Interface.WIFI_STATE_DISABLED:
Toast.makeText(this,"WiFi已经关闭",Toast.LENGTH_SHORT).show();
break;
caseWifiSwitch_Interface.WIFI_STATE_DISABLING:
Toast.makeText(this,"WiFi正在关闭",Toast.LENGTH_SHORT).show();
break;
caseWifiSwitch_Interface.WIFI_STATE_ENABLED:
Toast.makeText(this,"WiFi已经打开",Toast.LENGTH_SHORT).show();
break;
caseWifiSwitch_Interface.WIFI_STATE_ENABLING:
Toast.makeText(this,"WiFi正在打开",Toast.LENGTH_SHORT).show();
break;
}
}
@Override
protectedvoidonDestroy(){
super.onDestroy();
//释放资源
if(wifiSwitch_presenter!=null){
wifiSwitch_presenter.onDestroy();
}
