Android抽屜(SlidingDrawer)的實現

mainActivity如下:

package c.c;import android.app.Activity;import android.os.Bundle;import android.widget.SlidingDrawer;import android.widget.SlidingDrawer.OnDrawerCloseListener;import android.widget.SlidingDrawer.OnDrawerOpenListener;import android.widget.SlidingDrawer.OnDrawerScrollListener;/** * 需求描述: * 實現一個很簡單的抽屜Demo * 注意的問題: * 1 開啟抽屜的表徵圖,開啟後的介面都是布局在<SlidingDrawer/>中 * 2 在<SlidingDrawer/>中 *   使用:android:handle="@+id/handle_layout" *   指定抽屜的把手 *   使用:android:content="@+id/content_layout" *   指定開啟抽屜後的View * 3 SlidingDrawer一共有三個監聽事件(見代碼) *   注意三者的執行順序,總的原則是: *   滑動完成後,開啟(或者關閉)抽屜 *   所以:執行的順序 *   //1 setOnDrawerScrollListener *   //2 setOnDrawerOpenListener *       或setOnDrawerCloseListener */public class MainActivity extends Activity {    private SlidingDrawer mSlidingDrawer;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        init();    }    //執行的順序    //1 setOnDrawerScrollListener    //2 setOnDrawerOpenListener(或者setOnDrawerCloseListener)    private void init(){    mSlidingDrawer=(SlidingDrawer) findViewById(R.id.slidingDrawer);    mSlidingDrawer.setOnDrawerScrollListener(new OnDrawerScrollListener() {public void onScrollStarted() {    System.out.println("-------->  開始滑動");}public void onScrollEnded() { System.out.println("-------->  滑動結束");}});    mSlidingDrawer.setOnDrawerOpenListener(new OnDrawerOpenListener() {public void onDrawerOpened() {               System.out.println("-------->  開啟抽屜");}});    mSlidingDrawer.setOnDrawerCloseListener(new OnDrawerCloseListener() {public void onDrawerClosed() { System.out.println("-------->  關閉抽屜");}});    }}

main.xml如下:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentTop="true"        android:layout_centerHorizontal="true"        android:text="測試抽屜效果" />    <SlidingDrawer        android:id="@+id/slidingDrawer"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:handle="@+id/handle_layout"        android:content="@+id/content_layout"        android:orientation="horizontal">        <LinearLayout            android:id="@+id/handle_layout"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:orientation="horizontal" >            <ImageView                android:id="@+id/imageView"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:src="@drawable/ic_launcher" />        </LinearLayout>        <LinearLayout            android:id="@+id/content_layout"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:orientation="horizontal" >            <Button                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:text="Button1" />            <Button                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:text="Button2" />            <Button                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:text="Button3" />        </LinearLayout>    </SlidingDrawer></RelativeLayout>
