一、监听home键盘,Android Home键系统负责监听,捕获后系统自动处理。有时候,我们需要监听home键处理自己的逻辑,监听方法如下:
/** * 监听home键广播 */ private final static BroadcastReceiver homeListenerReceiver = new BroadcastReceiver() { final String SYSTEM_DIALOG_REASON_KEY = "reason"; final String SYSTEM_DIALOG_REASON_HOME_KEY = "homekey"; @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_DIALOG_REASON_KEY); if (reason != null && reason.equals(SYSTEM_DIALOG_REASON_HOME_KEY)) { // 处理自己的逻辑 } } } };
在创建View时注册Receiver IntentFilter homeFilter = new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS); context.registerReceiver(homeListenerReceiver, homeFilter);
在View消失时反注册Receiver // 反注册home监听 if (homeListenerReceiver != null) { context.unregisterReceiver(homeListenerReceiver); }
二、WindowManager view中监听返回及menu键
重写dispatchKeyEvent @Override public boolean dispatchKeyEvent(KeyEvent event) { switch (event.getKeyCode()) { case KeyEvent.KEYCODE_BACK: case KeyEvent.KEYCODE_MENU: // 处理自己的逻辑break; default: break; } return super.dispatchKeyEvent(event); }
