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@Overridepublic void onScreenOn() {    Log.d("xxxxx", "亮屏");}//息屏@Overridepublic void onScreenOff() {    Log.d("xxxxx", "息屏");}//锁屏@Overridepublic void onUserPresent() {    Log.d("xxxxx", "锁屏");}
