这篇文章主要为大家详细介绍了Android仿人人网滑动侧边栏效果，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
很多应用为了节省空间而又使界面能够充足的显示信息，大多数应用都采用了侧边栏的方式，如下图：
来说说它的思路，底下是两个或多个视图，分别通过控制它们的宽度、左边距来控制它们的显示，来看看代码
activity_main.xml
MainActivity.java
public class MainActivity extends Activity implements OnTouchListener { private LinearLayout menu; private LinearLayout content; private LayoutParams menuParams; private LayoutParams contentParams; // menu完全显示时，留给content的宽度值。 private static final int menuPadding = 80; // 分辨率 private int disPlayWidth; private float xDown; private float xMove; private boolean mIsShow = false; private static final int speed = 50; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_main); disPlayWidth = getWindowManager().getDefaultDisplay().getWidth(); menu = (LinearLayout) findViewById(R.id.menu); content = (LinearLayout) findViewById(R.id.content); menuParams = (LayoutParams) menu.getLayoutParams(); contentParams = (LayoutParams) content.getLayoutParams(); findViewById(R.id.layout).setOnTouchListener(this); menuParams.width = disPlayWidth - menuPadding; contentParams.width = disPlayWidth; showMenu(mIsShow); } @Override public boolean onTouch(View v, MotionEvent event) { switch (event.getAction()) { case MotionEvent.ACTION_DOWN: showMenu(!mIsShow); break; case MotionEvent.ACTION_MOVE: break; case MotionEvent.ACTION_UP: break; } return true; } private void showMenu(boolean isShow) { if (isShow) { mIsShow = true; menuParams.leftMargin = 0; } else { mIsShow = false; menuParams.leftMargin = 0 - menuParams.width; } menu.setLayoutParams(menuParams); } } 上述代码只是用两张图片代替了两个复杂的view(layout)，你会发现，两个视图虽然可以切换，但没有动画的感觉，再加上要有拖动效果，所以，我们再给它加个平移时间段，看起来有动画的效果
