android home 键的监听方法记录

（1）在activity里面重载这个方法

@Override
    protected void onUserLeaveHint() {
        Log.d("aeon","onUserLeaveHint");
        super.onUserLeaveHint();

}

（2）监听home键广播

public class HomeListener {
static final String TAG = "HomeListener";
private Context mContext;
private IntentFilter mFilter;
private OnHomePressedListener mListener;
private InnerRecevier mRecevier;

// 回调接口
public interface OnHomePressedListener {
public void onHomePressed();

public void onHomeLongPressed();
}

public HomeListener(Context context) {
mContext = context;
mFilter = new IntentFilter(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
}

/**
* 设置监听
*
* @param listener
*/
public void setOnHomePressedListener(OnHomePressedListener listener) {
mListener = listener;
mRecevier = new InnerRecevier();
}

/**
* 开始监听，注册广播
*/
public void startWatch() {
if (mRecevier != null) {
mContext.registerReceiver(mRecevier, mFilter);
}
}

/**
* 停止监听，注销广播
*/
public void stopWatch() {
if (mRecevier != null) {
mContext.unregisterReceiver(mRecevier);
}
}

/**
* 广播接收者
*/
class InnerRecevier extends BroadcastReceiver {
final String SYSTEM_DIALOG_REASON_KEY = "reason";
final String SYSTEM_DIALOG_REASON_GLOBAL_ACTIONS = "globalactions";
final String SYSTEM_DIALOG_REASON_RECENT_APPS = "recentapps";
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) {
// Log.e(TAG, "action:" + action + ",reason:" + reason);
if (mListener != null) {
if (reason.equals(SYSTEM_DIALOG_REASON_HOME_KEY)) {
// 短按home键
mListener.onHomePressed();
} else if (reason
.equals(SYSTEM_DIALOG_REASON_RECENT_APPS)) {
// 长按home键
mListener.onHomeLongPressed();
}
}
}
}
}
}

}

public class MainActivity extends Activity {
boolean mIsSupportedBade = true;
String tag="hyy";
private HomeListener mHomeWatcher;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mHomeWatcher = new HomeListener(this);
mHomeWatcher.setOnHomePressedListener(new OnHomePressedListener() {

}catch(Exception e){

}
}

@Override

mHomeWatcher.stopWatch();// 在onPause中停止监听，不然会报错的。
}
@Override

Log.e(tag, "onStop调用了");
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
