监听屏幕唤醒,息屏,亮屏的

首先是一个封装类

public class ScreenObserver {
    private static String TAG = "ScreenObserver";
    private Context mContext;
    private ScreenBroadcastReceiver mScreenReceiver;
    private ScreenStateListener mScreenStateListener;
    private static Method mReflectScreenState;

    public ScreenObserver(Context context) {
        mContext = context;
        mScreenReceiver = new ScreenBroadcastReceiver();
        try {
            mReflectScreenState = PowerManager.class.getMethod("isScreenOn",
                    new Class[]{});
        } catch (Exception nsme) {
            Log.d(TAG, "API < 7," + nsme);
        }
    }

    /**  * screen状态广播接收者  */  private class ScreenBroadcastReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            if (Intent.ACTION_SCREEN_ON.equals(intent.getAction())) {
                mScreenStateListener.onScreenOn();
            } else if (Intent.ACTION_SCREEN_OFF.equals(intent.getAction())) {
                mScreenStateListener.onScreenOff();
            } else if (Intent.ACTION_USER_PRESENT.equals(intent.getAction())) {
                mScreenStateListener.onUserPresent();
            }
        }
    }

    /**  * 请求screen状态更新  */  public void requestScreenStateUpdate(ScreenStateListener listener) {
        mScreenStateListener = listener;
        startScreenBroadcastReceiver();
        firstGetScreenState();
    }

    /**  * 第一次请求screen状态  */  private void firstGetScreenState() {
        PowerManager manager = (PowerManager) mContext
                .getSystemService(Activity.POWER_SERVICE);
        if (isScreenOn(manager)) {
            if (mScreenStateListener != null) {
                mScreenStateListener.onScreenOn();
            }
        } else {
            if (mScreenStateListener != null) {
                mScreenStateListener.onScreenOff();
            }
        }
    }

    /**  * 停止screen状态更新  */  public void stopScreenStateUpdate() {
        mContext.unregisterReceiver(mScreenReceiver);
    }

    /**  * 启动screen状态广播接收器  */  private void startScreenBroadcastReceiver() {
        IntentFilter filter = new IntentFilter();
        filter.addAction(Intent.ACTION_SCREEN_ON);
        filter.addAction(Intent.ACTION_SCREEN_OFF);
        filter.addAction(Intent.ACTION_USER_PRESENT);
        mContext.registerReceiver(mScreenReceiver, filter);
    }

    /**  * screen是否打开状态  */  private static boolean isScreenOn(PowerManager pm) {
        boolean screenState;
        try {
            screenState = (Boolean) mReflectScreenState.invoke(pm);
        } catch (Exception e) {
            screenState = false;
        }
        return screenState;
    }

    // 外部调用接口
    public interface ScreenStateListener {
        public void onScreenOn();

        public void onScreenOff();

        public void onUserPresent();
    }

    public final static boolean isScreenLocked(Context c) {
        android.app.KeyguardManager mKeyguardManager = (KeyguardManager) c
                .getSystemService(c.KEYGUARD_SERVICE);
        return mKeyguardManager.inKeyguardRestrictedInputMode();
    }
}

用法::::::::::::::::::::::::::::::::::::::::::::::::::::::::::在主的界面上

//订阅
screenObserver.requestScreenStateUpdate(this);

实现接口

//亮屏
@Override
public void onScreenOn() {
    Log.d("xxxxx", "亮屏");
}

//息屏
@Override
public void onScreenOff() {
    Log.d("xxxxx", "息屏");

}

//锁屏
@Override
public void onUserPresent() {
    Log.d("xxxxx", "锁屏");

}
