Android HOME键那些事

app中对于HOME键广播事件的接收
首先，自定义一个BroadcastReceiver：
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
}
}
}
}
}

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