ANDROID监听home键的实现步骤
第一步 注册系统广播
registerReceiver(mHomeKeyEventReceiver, new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS));
第二步 建立广播接收器
private BroadcastReceiver mHomeKeyEventReceiver = new BroadcastReceiver() {
String SYSTEM_REASON = "reason";//参数key
String SYSTEM_HOME_KEY = "homekey";
String SYSTEM_HOME_KEY_LONG = "recentapps";
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)) { // 监听home键
String reason = intent.getStringExtra(SYSTEM_REASON);
Toast.makeText(InitActivity.this,reason,Toast.LENGTH_SHORT).show();
// 表示按了home键,程序到了后台
}
}
};
