要是实现这样的功能很简单，就是SlidingDrawer的使用

效果如下图：手指按住Notification往上/往下拉动，显示/隐藏notification content

XML

<?xml version="1.0" encoding="utf-8"?><LinearLayout android:id="@+id/LinearLayout01"    android:layout_width="fill_parent" android:layout_height="fill_parent"    xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical" android:gravity="bottom">    <SlidingDrawer android:layout_width="wrap_content"        android:id="@+id/SlidingDrawer" android:handle="@+id/slideHandleButton"        android:content="@+id/contentLayout" android:padding="10dip"        android:layout_height="200dip">        <Button android:layout_width="wrap_content"            android:layout_height="wrap_content" android:id="@+id/slideHandleButton"            android:background="@drawable/arrowup"></Button>        <LinearLayout android:layout_width="wrap_content"            android:id="@+id/contentLayout" android:orientation="vertical"            android:gravity="center|top" android:padding="10dip"            android:background="#505050" android:layout_height="wrap_content">            <TextView android:id="@+id/TextView01" android:layout_width="wrap_content"                android:layout_height="fill_parent" android:layout_weight="8" android:text="Hello Slider"></TextView>            <Button android:id="@+id/Button02" android:layout_weight="2" android:layout_width="wrap_content"                android:layout_height="wrap_content" android:text="Do anything"></Button>        </LinearLayout>    </SlidingDrawer></LinearLayout>

activity

public class SliderActivity extends Activity {    Button slideHandleButton;    SlidingDrawer slidingDrawer;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        slideHandleButton = (Button) findViewById(R.id.slideHandleButton);        slidingDrawer = (SlidingDrawer) findViewById(R.id.SlidingDrawer);        slidingDrawer.setOnDrawerOpenListener(new OnDrawerOpenListener() {            @Override            public void onDrawerOpened() {                slideHandleButton.setBackgroundResource(R.drawable.arrowdown);            }        });        slidingDrawer.setOnDrawerCloseListener(new OnDrawerCloseListener() {            @Override            public void onDrawerClosed() {                slideHandleButton.setBackgroundResource(R.drawable.arrowup);            }        });    }}

不用讲解，layout.xml和java代码很清晰。
