仿照网易云和QQ音乐的锁屏效果

音乐app锁屏效果

参考网址:http://www.android100.org/html/201509/01/178176.html

使用三方侧滑库: https://github.com/ikew0ng/SwipeBackLayout

自己实现代码:

public class MyService extends Service {

@Nullable

@Override

public IBinder onBind(Intent intent) {

return null;

}@Override

public int onStartCommand(Intent intent, int flags, int startId) {

return super.onStartCommand(intent, flags, startId);

}

@Override

public void onCreate() {

super.onCreate();

ScreenReceiver screenReceiver = new ScreenReceiver();

IntentFilter filter = new IntentFilter();

filter.addAction(Intent.ACTION_SCREEN_OFF);

filter.addAction(Intent.ACTION_SCREEN_ON);

registerReceiver(screenReceiver, filter);

}

public class ScreenReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

if (Intent.ACTION_SCREEN_OFF.equals(action)) {

Log.e("tzhhh","锁屏了");

} else if (Intent.ACTION_SCREEN_ON.equals(action)) {

Intent lockscreen = new Intent(MyService.this, LockScreenActivity.class);

lockscreen.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

startActivity(lockscreen);

System.out.println("屏幕开启了");

}

}

}

}

public class LockScreenActivity extends SwipeBackActivity {

@Override

protected void onCreate(@Nullable Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

this.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD | WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);

setContentView(R.layout.activity_lock);

SwipeBackLayout swipeBackLayout = getSwipeBackLayout();

swipeBackLayout.setEdgeTrackingEnabled(SwipeBackLayout.EDGE_LEFT);

}

}

android:name=".LockScreenActivity"

android:excludeFromRecents="true"

android:exported="false"

android:launchMode="singleInstance"

android:screenOrientation="portrait"

android:taskAffinity="com.package.name.lockscreen"
