Android抽屉(SlidingDrawer)的实现
mainActivity如下:[java]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:* 实现一个很简单的抽屉Demo* 注意的问题:* 1 打开抽屉的图标,打开后的界面都是布局在<SlidingDrawer/>中* 2 在<SlidingDrawer/>中* 使用:android:handle="@+id/handle_layout"* 指定抽屉的把手* 使用:android:content="@+id/content_layout"* 指定打开抽屉后的View* 3 SlidingDrawer一共有三个监听事件(见代码)* 注意三者的执行顺序,总的原则是:* 滑动完成后,打开(或者关闭)抽屉* 所以:执行的顺序* //1 setOnDrawerScrollListener* //2 setOnDrawerOpenListener* 或setOnDrawerCloseListener*/public class MainActivity extends Activity {private SlidingDrawer mSlidingDrawer;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);init();}//执行的顺序//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("--------> 开始滑动");}public void onScrollEnded() {System.out.println("--------> 滑动结束");}});mSlidingDrawer.setOnDrawerOpenListener(new OnDrawerOpenListener() {public void onDrawerOpened() {System.out.println("--------> 打开抽屉");}});mSlidingDrawer.setOnDrawerCloseListener(new OnDrawerCloseListener() {public void onDrawerClosed() {System.out.println("--------> 关闭抽屉");}});}}main.xml如下:[html]<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" ><TextViewandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignParentTop="true"android:layout_centerHorizontal="true"android:text="测试抽屉效果" /><SlidingDrawerandroid: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"><LinearLayoutandroid:id="@+id/handle_layout"android:layout_width="wrap_content"android:layout_height="wrap_content"android:orientation="horizontal" ><ImageViewandroid:id="@+id/imageView"android:layout_width="wrap_content"android:layout_height="wrap_content"android:src="@drawable/ic_launcher" /></LinearLayout><LinearLayoutandroid:id="@+id/content_layout"android:layout_width="wrap_content"android:layout_height="wrap_content"android:orientation="horizontal" ><Buttonandroid:layout_width="wrap_content"android:layout_height="wrap_content"android:text="Button1" /><Buttonand补充:移动开发 , Android ,
上一个:android删除文件权限
下一个:android 的导航界面的设计与实现
