SlidingDrawer 抽屉效果

一、简介　　SlidingDrawer隐藏屏外的内容，并允许用户通过handle以显示隐藏内容。它可以垂直或水平滑动，，它有俩个View组成，其一是可以拖动的handle,其二是隐藏内容的View.它里面的控件必须设置布局，在布局文件中必须指定handle和content.例如下面<SlidingDrawer android:layout_width="fill_parent" android:layout_height="fill_parent" android:handle="@+id/handle" android:content="@+id/content" android:orientation="vertical" android:id="@+id/slidingdrawer"> <ImageButton android:id="@id/handle" android:layout_width="50dip" android:layout_height="44dip" android:src="@drawable/up" /> <LinearLayout android:id="@id/content" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#ffffff"> <TextView android:text="这是一个滑动式抽屉的示例" android:id="@+id/tv" android:textSize="18px" android:textColor="#000000" android:gravity="center_vertical|center_horizontal" android:layout_width="match_parent" android:textStyle="bold" android:layout_height="match_parent"></TextView> </LinearLayout></SlidingDrawer>二、重要属性　　android:allowSingleTap：指示是否可以通过handle打开或关闭　　android:animateOnClick：指示是否当使用者按下手柄打开/关闭时是否该有一个动画。　　android:content：隐藏的内容　　android:handle：handle（手柄）三、重要方法　　animateClose()：关闭时实现动画。　　close()：即时关闭　　getContent()：获取内容　　isMoving()：指示SlidingDrawer是否在移动。　　isOpened()：指示SlidingDrawer是否已全部打开　　lock()：屏蔽触摸事件。　　setOnDrawerCloseListener(SlidingDrawer.OnDrawerCloseListener onDrawerCloseListener)：SlidingDrawer关闭时调用　　unlock()：解除屏蔽触摸事件。　　toggle()：切换打开和关闭的抽屉SlidingDrawer。四、完整实例1.布局文件slidingdrawer.xml<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android=""android:layout_width="fill_parent" android:layout_height="fill_parent"android:orientation="vertical" android:background="@drawable/default_bg"><SlidingDrawer android:layout_width="fill_parent" android:layout_height="fill_parent" android:handle="@+id/handle" android:content="@+id/content" android:orientation="vertical" android:id="@+id/slidingdrawer"> <ImageButton android:id="@id/handle" android:layout_width="50dip" android:layout_height="44dip" android:src="@drawable/up" /> <LinearLayout android:id="@id/content" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#ffffff"> <TextView android:text="这是一个滑动式抽屉的示例" android:id="@+id/tv" android:textSize="18px" android:textColor="#000000" android:gravity="center_vertical|center_horizontal" android:layout_width="match_parent" android:textStyle="bold" android:layout_height="match_parent"></TextView> </LinearLayout></SlidingDrawer></LinearLayout>2.Java代码package com.wjq;import android.app.Activity;import android.os.Bundle;import android.widget.ImageButton;import android.widget.SlidingDrawer;import android.widget.TextView;public class SlidingDrawerDemo extends Activity {private SlidingDrawer mDrawer;private ImageButton imbg;private Boolean flag=false;private TextView tv;/* (non-Javadoc) * @see android.app.Activity#onCreate(android.os.Bundle) */@Overrideprotected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.sildingdrawer); imbg=(ImageButton)findViewById(R.id.handle); mDrawer=(SlidingDrawer)findViewById(R.id.slidingdrawer); tv=(TextView)findViewById(R.id.tv); mDrawer.setOnDrawerOpenListener(new SlidingDrawer.OnDrawerOpenListener() { @Override public void onDrawerOpened() { flag=true; imbg.setImageResource(R.drawable.down); } }); mDrawer.setOnDrawerCloseListener(new SlidingDrawer.OnDrawerCloseListener(){ @Override public void onDrawerClosed() { flag=false; imbg.setImageResource(R.drawable.up); } }); mDrawer.setOnDrawerScrollListener(new SlidingDrawer.OnDrawerScrollListener(){ @Override public void onScrollEnded() { tv.setText("结束拖动"); } @Override public void onScrollStarted() { tv.setText("开始拖动"); } });}}
