Android 自定义锁屏(带页面切换)

我简单的了解一下自定义锁屏,顺便总结了一下思路顺便画个图帮助理解

我的效果图

代码思路
锁屏分为两块,一块是UI(自定义布局)另一块这就是服务了

自定义锁屏布局
ACTION_DOWN按下:中间的ImageView会变成另一种形态
ACTION_MOVE移动: 移动到左/右边,左/右ImageView形态也要发生变化,
ACTION_UP抬起:判断滑动到左/右那边,或者回到最初位置

*服务

 @Override    public void onCreate() {        super.onCreate();        mContext = getApplicationContext();        //管理打开的窗口程序        mWinMng = (WindowManager) mContext.getSystemService(Context.WINDOW_SERVICE);        i = new Intent(mContext, MyService.class);        i.setAction(MyService.LOCK_ACTION);        zdLockIntent = new Intent(MyService.this , MyService.class);        //设置此状态，首先会查找是否存在和被启动的Activity具有相同的亲和性的任务栈        zdLockIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);        /*注册广播*/        IntentFilter mScreenOnFilter = new IntentFilter("android.intent.action.SCREEN_ON");        MyService.this.registerReceiver(mScreenOnReceiver, mScreenOnFilter);        /*注册广播*/        IntentFilter mScreenOffFilter = new IntentFilter("android.intent.action.SCREEN_OFF");        MyService.this.registerReceiver(mScreenOffReceiver, mScreenOffFilter);    }

这个View 就是之前自定义的View,我只说说核心的代码 稍后上Demo

    @Override    public int onStartCommand(Intent intent, int flags, int startId) {        if(intent!=null){            String action = intent.getAction();            if(TextUtils.equals(action, LOCK_ACTION))                //锁屏添加view                addView();            else if(TextUtils.equals(action, UNLOCK_ACTION))            {    //解屏移除view                removeView();            }        }        return Service.START_STICKY;    }

当程序销毁的时候.服务要重新启动,不然这个app的锁屏,会随着app的销毁而被销毁

  @Override    public void onDestroy(){        super.onDestroy();        MyService.this.unregisterReceiver(mScreenOnReceiver);        MyService.this.unregisterReceiver(mScreenOffReceiver);        //在此重新启动        startService(new Intent(MyService.this, MyService.class));    }

当屏幕变量或者变暗的时候,要解除屏幕锁定的方法,如果不解除 那只能一直锁着了=_=

  //屏幕变亮的广播,我们要隐藏默认的锁屏界面    private BroadcastReceiver mScreenOnReceiver = new BroadcastReceiver(){        @Override        public void onReceive(Context context , Intent intent) {            Log.i(TAG, intent.getAction());            if(intent.getAction().equals("android.intent.action.SCREEN_ON")){                //键盘锁的服务                mKeyguardManager = (KeyguardManager)context.getSystemService(Context.KEYGUARD_SERVICE);                mKeyguardLock = mKeyguardManager.newKeyguardLock("zdLock 1");                mKeyguardLock.disableKeyguard();                startService(i);            }        }    };      //屏幕变暗/变亮的广播 ， 我们要调用KeyguardManager类相应方法去解除屏幕锁定    private BroadcastReceiver mScreenOffReceiver = new BroadcastReceiver(){        @Override        public void onReceive(Context context , Intent intent) {            String action = intent.getAction() ;            Log.i(TAG, intent.toString());            if(action.equals("android.intent.action.SCREEN_OFF")                    || action.equals("android.intent.action.SCREEN_ON") ){                mKeyguardManager = (KeyguardManager)context.getSystemService(Context.KEYGUARD_SERVICE);                mKeyguardLock = mKeyguardManager.newKeyguardLock("zdLock 1");                mKeyguardLock.disableKeyguard();                startService(i);            }        }    };

权限问题

  <uses-permission android:name="android.permission.DISABLE_KEYGUARD" /><!-- 屏蔽HOME键需要的权限 -->    <uses-permission android:name="android.permission.VIBRATE" />    <uses-permission android:name="android.permission.DISABLE_KEYGUARD" />    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />

这个锁屏Demo涉及到的东西有点多,我写的这个博客掐不住重点,写的繁琐反而浪费大家时间,什么也不说了全在代码中↓

补充一点
用小米手机当测试机，一定要把这个Demo锁屏权限打开，手机设置中找到app，打开锁屏。不然一运行就崩掉
