SlidingDrawer類雖然已經不推薦使用了，但有時如果效果簡單的話用用也無妨，反正我有有點懷念，主要是它使用簡單，只能上下或者左右滑動，而且剛開始的時候，方向不能指定，

布局文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
??? android:layout_width="match_parent"
??? android:layout_height="match_parent" ?
??? android:orientation="vertical"
??? android:background="#000099">
?? ?
??? <SlidingDrawer
??????? android:id="@+id/slidingdrawer"
??????? android:layout_width="match_parent"
??????? android:layout_height="wrap_content"
??????? android:content="@+id/content"
??????? android:handle="@+id/handle"
??????? android:orientation="vertical" >
??????? <ImageView
??????????? android:id="@id/handle"
??????????? android:layout_width="wrap_content"
??????????? android:layout_height="wrap_content"
??????????? android:src="@drawable/lo19" >
??????? </ImageView>
??????? <LinearLayout
??????????? android:id="@id/content"
??????????? android:layout_width="match_parent"
??????????? android:layout_height="match_parent"
??????????? android:background="#008800">
??????????? <TextView
??????????????? android:layout_width="match_parent"
??????????????? android:layout_height="match_parent"
??????????????? android:text="隱藏的內容"/>
??????? </LinearLayout>
??? </SlidingDrawer>
??? <TextView
??????? android:layout_width="match_parent"
??????? android:layout_height="wrap_content"
??????? android:text="bottom textView"
??????? android:textAppearance="?android:attr/textAppearanceLarge"
??????? android:gravity="center_vertical|center_horizontal"/>
</LinearLayout>

在主界面中不寫什么代碼就可以滑了，

如果要寫一些方法，主要是下面幾個方法

SlidingDrawer sd = (SlidingDrawer)findViewById(R.id.slidingdrawer);?
?????????
??????? sd.setOnDrawerOpenListener(new OnDrawerOpenListener(){?
??????????? public void onDrawerOpened() {?
??????????????? // TODO Auto-generated method stub?
??????????? }?
??????? });?
??????? sd.setOnDrawerCloseListener(new OnDrawerCloseListener(){?
??????????? public void onDrawerClosed() {?
??????????????? // TODO Auto-generated method stub?
??????????? }?
??????? });?
??????? sd.setOnDrawerScrollListener(new OnDrawerScrollListener(){?
??????????? public void onScrollEnded() {?
??????????????? // TODO Auto-generated method stub?
??????????? }?
??????????? public void onScrollStarted() {?
??????????????? // TODO Auto-generated method stub?
??????????? }????
??????? });

下面這抽屜把手機上的應用程序的圖標在抽屜中以縮小的圖標來顯示，這是轉自網絡的， 我覺得可能以后有用就收藏到此了，如有侵僅，還請告知

操作上面配置的文件的Activity類

package com.example.t;

import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.SlidingDrawer;
//這個類把所有應用程序的圖標都縮小化了以抽屜的方式顯示
public class MainActivity extends Activity {

?? ?private GridView gv; ?
??? private SlidingDrawer sd; ?
??? private ImageView iv; ?
??? private List<ResolveInfo> apps; ?
?
