SlideringDrawer的使用(抽屜效果)

一  SlidingDrawer 這個類，也就是所謂的"抽屜"類。它的用法很簡單，要包括handle ,和content .

handle 就是當你點擊它的時候，content 要么抽抽屜要么關抽屜。

這是上下拉抽屜的效果，將 SlidingDrawer屬性設置為android:orientation="vertical"即可

  

這是左右拉抽屜的效果，將 SlidingDrawer屬性設置為android:orientation="horizontal"即可。

二、重要屬性

　　android:allowSingleTap：指示是否可以通過handle打開或關閉

　　android:animateOnClick：指示是否當使用者按下手柄打開/關閉時是否該有一個動畫。

　　android:content：隱藏的內容

　　android:handle：handle(手柄)

　　三、重要方法

　　animateClose()：關閉時實現動畫。

     close()：即時關閉

　　getContent()：獲取內容

　　isMoving()：指示SlidingDrawer是否在移動。

　　isOpened()：指示SlidingDrawer是否已全部打開

　　lock()：屏蔽觸摸事件。

　　setOnDrawerCloseListener(SlidingDrawer.OnDrawerCloseListener onDrawerCloseListener)：SlidingDrawer關閉時調用

　　unlock()：解除屏蔽觸摸事件。

　　toggle()：切換打開和關閉的抽屜SlidingDrawer。

上面例子的布局文件：

<?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="效果顯示：" /> <SlidingDrawer android:id="@+id/drawer1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal" android:handle="@+id/layout1" android:content="@+id/mycontent1"> <LinearLayout android:id="@id/layout1" android:orientation="vertical" android:layout_width="35sp" android:layout_height="wrap_content" android:gravity="center"> <ImageView android:id="@+id/myImage" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/open" /> </LinearLayout> <GridView android:id="@id/mycontent1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:numColumns="2" android:gravity="center" /> </SlidingDrawer> </LinearLayout> </FrameLayout>

java文件：

import android.app.Activity; import android.os.Bundle; import android.widget.GridView; import android.widget.ImageView; import android.widget.SlidingDrawer; import android.widget.SlidingDrawer.OnDrawerCloseListener; import android.widget.SlidingDrawer.OnDrawerOpenListener; import android.widget.SlidingDrawer.OnDrawerScrollListener; public class SlidingDrawerActivity extends Activity { /** Called when the activity is first created. */ private SlidingDrawer sd; private GridView gv; private ImageView iv; private int [] itemIcons = new int [] { R.drawable.alarm, R.drawable.calendar, R.drawable.camera, R.drawable.clock, R.drawable.music, R.drawable.tv }; private String[] itemString = new String[]{"Alarm","Calendar","camera","clock","music","tv"}; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.slidrawer); init(); GridAdapter adapter = new GridAdapter(SlidingDrawerActivity.this,itemString,itemIcons); gv.setAdapter(adapter); /* 設定SlidingDrawer被打開的事件處理 */ sd.setOnDrawerOpenListener(new OnDrawerOpenListener() { @Override public void onDrawerOpened() { // TODO Auto-generated method stub iv.setImageResource(R.drawable.close); } }); /* 設定SlidingDrawer被關閉的事件處理 */ sd.setOnDrawerCloseListener(new OnDrawerCloseListener() { public void onDrawerClosed() { iv.setImageResource(R.drawable.open); } }); sd.setOnDrawerScrollListener(new OnDrawerScrollListener() { @Override public void onScrollStarted() { // TODO Auto-generated method stub System.out.println("start"); } @Override public void onScrollEnded() { // TODO Auto-generated method stub System.out.println("end"); } }); } private void init(){ sd = (SlidingDrawer) findViewById(R.id.drawer1); gv = (GridView) findViewById(R.id.mycontent1); iv = (ImageView) findViewById(R.id.myImage); } }

package com.shao.slider; import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.ImageView; import android.widget.TextView; public class GridAdapter extends BaseAdapter { private Context context; private String[] itemString; private int[] itemIcons; public GridAdapter(Context con,String[] itemString,int[] itemIcons){ context = con; this.itemString = itemString; this.itemIcons = itemIcons; } @Override public int getCount() { // TODO Auto-generated method stub return itemIcons.length; } @Override public Object getItem(int position) { // TODO Auto-generated method stub return itemString[position]; } @Override public long getItemId(int position) { // TODO Auto-generated method stub return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub LayoutInflater inflater = LayoutInflater.from(context); /* 使用item.xml為每幾個item的Layout */ View v = inflater.inflate(R.layout.item, null); /* 取得View */ ImageView iv = (ImageView) v.findViewById(R.id.item_grid); TextView tv = (TextView) v.findViewById(R.id.item_text); /* 設定顯示的Image與文? */ iv.setImageResource(itemIcons[position]); tv.setText(itemString[position]); return v; } }

還有注意的是：

SlidingDrawer should be used as an overlay inside layouts. This means SlidingDrawer should only be used inside of a FrameLayout or a RelativeLayout for       instance,如果顯示的時候不正常，考慮上面的原因。
