看代码：

import com.ucoupon.uplus.MyApplication;
    import com.ucoupon.uplus.utils.LogUtils;
    
    import android.content.BroadcastReceiver;
    import android.content.Context;
    import android.content.Intent;
    /**
     * Home键和锁屏监听
     * Title: HomeWatcherReceiver.java
     * @author wang
     * 2016年4月25日
     * @version 1.0
     */
    public class HomeWatcherReceiver extends BroadcastReceiver {
    //	private static final String LOG_TAG = "HomeReceiver";
    	private static final String SYSTEM_DIALOG_REASON_KEY = "reason";
    	private static final String SYSTEM_DIALOG_REASON_RECENT_APPS = "recentapps";
    	private static final String SYSTEM_DIALOG_REASON_HOME_KEY = "homekey";
    	private static final String SYSTEM_DIALOG_REASON_ASSIST = "assist";
    
    	@Override
    	public void onReceive(Context context, Intent intent) {
    		String action = intent.getAction();
    		LogUtils.log_e("action......", action);
    		
    		if (action.equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)) {
    			
    			String reason = intent.getStringExtra(SYSTEM_DIALOG_REASON_KEY);
    			LogUtils.log_e("reason......", reason);
    			if (SYSTEM_DIALOG_REASON_HOME_KEY.equals(reason)) {
    				// 短按Home键
    				MyApplication.setUpMap = true;
    				LogUtils.log_e("home", "短按Home键");
    			} else if (SYSTEM_DIALOG_REASON_RECENT_APPS.equals(reason)) {
    				// 长按Home键 或者 activity切换键
    				LogUtils.log_e("home", "长按Home键");
    			} else if (SYSTEM_DIALOG_REASON_ASSIST.equals(reason)) {
    				// samsung 长按Home键
    				LogUtils.log_e("home", "samsung长按Home键");
    			}
    
    		}
    		if(action.equals(Intent.ACTION_SCREEN_ON)){
    			LogUtils.log_e("lock", "Screen is on");
    		}else if(action.equals(Intent.ACTION_SCREEN_OFF)){
    			LogUtils.log_e("lock", "Screen is off");
    			MyApplication.setUpMap = true;
    		}
    	}
    
    }

在MainActivity中添加代码：

private HomeWatcherReceiver receiver;
    
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.activity_main);
    		
    		
    		registerHomeKeyReceiver();
    	}

// 注册锁屏监听
    	private void registerHomeKeyReceiver() {
    		receiver = new HomeWatcherReceiver();
    		final IntentFilter filter = new IntentFilter();
    		filter.addAction(Intent.ACTION_SCREEN_ON);
        	filter.addAction(Intent.ACTION_SCREEN_OFF);
        	filter.addAction(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
    		registerReceiver(receiver, filter);
    		LogUtils.log_e("注册监听", "注册监听");
    	}
    
    	// 取消锁屏监听
    	private void unregisterHomeKeyReceiver() {
    		if (null != receiver) {
    			unregisterReceiver(receiver);
    		}
    		LogUtils.log_e("取消注册监听", "取消注册监听");
    	}

销毁

@Override
    	protected void onDestroy() {
    		super.onDestroy();
    		unregisterHomeKeyReceiver();
    	}
