android锁屏软件打造

一、首先要创建一个Service保证Service一直开启，同时不被一键清理掉。

二、屏蔽掉系统的锁屏

三、创建锁屏的Activity，在Activity中屏蔽掉back,menu,home键

四、保证自己的进程不在最近任务中出现

一、创建一个Service名字为LockService

public class LockService extends Service{	private KeyguardManager km;	private KeyguardLock kk;	private BroadcastReceiver broadcastReceiver=new BroadcastReceiver() {				@Override		public void onReceive(Context context, Intent arg1) {			Log.e("-----可以跳到锁屏界面--------", "---------");			Intent intent=new Intent(context,LockActivity.class);			intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);			startActivity(intent);		}	};	@Override	public IBinder onBind(Intent arg0) {				return null;	}	@Override	public void onStart(Intent intent, int startId) {		super.onStart(intent, startId);				//服务里面收到关闭屏幕的动作就发送广播		IntentFilter iFilter=new IntentFilter(Intent.ACTION_SCREEN_OFF);		this.registerReceiver(broadcastReceiver, iFilter);	}	@Override	public void onCreate() {		super.onCreate();		//屏蔽掉系统的锁屏		km=(KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);		kk=km.newKeyguardLock("");		kk.disableKeyguard();	}		@Override	public void onDestroy() {		super.onDestroy();	}	}

三、锁屏界面中屏蔽掉menu,home,back

public class LockActivity extends Activity{	private  static final int FLAG_HOMEKEY_DISPATCHED = 0x80000000;	private Button btn_open;	@Override	protected void onCreate(Bundle savedInstanceState) {		// TODO Auto-generated method stub		super.onCreate(savedInstanceState);		this.getWindow().setFlags(FLAG_HOMEKEY_DISPATCHED, FLAG_HOMEKEY_DISPATCHED);//关键代码 		setContentView(R.layout.activity_main);		//解锁的按钮		btn_open=(Button) findViewById(R.id.open);				btn_open.setOnClickListener(new OnClickListener() {						@Override			public void onClick(View arg0) {				finish();			}		});	}	@SuppressWarnings("static-access")	@Override	public boolean onKeyDown(int keyCode, KeyEvent event) {		if(keyCode==event.KEYCODE_BACK){			return true;		}		if(keyCode==event. KEYCODE_HOME){			return true;		}		if(keyCode == KeyEvent.KEYCODE_MENU) {//MENU键	        //监控/拦截菜单键	         return true;	    }     		return super.onKeyDown(keyCode, event);	}}

       <activity            android:name="com.mm.wallpaper.LockActivity"           android:launchMode="singleInstance"           android:excludeFromRecents="true">		<intent-filter>                <category android:name="android.intent.category.LAUNCHER" />                <category android:name="android.intent.category.DEFAULT" />            </intent-filter>       </activity>

public class MainActivity extends Activity {	MyBroadcast receiveBroadCast;	@Override	protected void onCreate(Bundle savedInstanceState) {		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_main);		//注册广播		receiveBroadCast = new MyBroadcast();		IntentFilter filter = new IntentFilter();		filter.addAction("action"); // 只有持有相同的action的接受者才能接收此广播		registerReceiver(receiveBroadCast, filter);				//发送广播		Intent intent=new Intent();		intent.setAction("action");		this.sendBroadcast(intent);			}	public class MyBroadcast extends BroadcastReceiver{		@Override		public void onReceive(Context context, Intent intent) {			KeyguardManager km = (KeyguardManager)context.getSystemService(Context.KEYGUARD_SERVICE);			KeyguardLock kk = km.newKeyguardLock("");			kk.disableKeyguard();						//开始服务			Intent service=new Intent();			service.setClass(context,LockService.class);//稍后再定义			context.startService(service);		}			}	@Override	protected void onDestroy() {		// TODO Auto-generated method stub		super.onDestroy();		unregisterReceiver(receiveBroadCast);	}	}

在配置清单中MainActivity需要多一个属性来保证程序始终在

   <category android:name="android.intent.category.HOME"/>
