Android监听HOME按键

大家可能或多或少在开发过程中遇到过监听HOME键的需求，但是使出了浑身解数也不一定能够监听到，当然除开系统开发的童鞋哈，下面给大家介绍的方法我在项目中已经测试过了，是可行的，方法就是利用广播来实现。代码如下:

view plaincopy
to clipboardprint?

class HomeKeyEventBroadCastReceiver extends BroadcastReceiver {

static final String SYSTEM_REASON = "reason";

static final String SYSTEM_HOME_KEY = "homekey";//home key

static final String SYSTEM_RECENT_APPS = "recentapps";//long home key

@Override

public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

if (action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)) {

String reason = intent.getStringExtra(SYSTEM_REASON);

if (reason != null) {

if (reason.equals(SYSTEM_HOME_KEY)) {

// home key处理点

} else if (reason.equals(SYSTEM_RECENT_APPS)) {

// long home key处理点

}

}

}

}

}

然后当然需要在onCreate里面注册该广播：

view plaincopy
to clipboardprint?

receiver = new HomeKeyEventBroadCastReceiver();

registerReceiver(receiver, new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS));

也需要在onDestroy里面解除该广播哦！
