Android中SlidingDrawer介绍【安卓进化三十四】

安卓中1.5后加入了SlidingDrawer【隐藏式抽屉】，设计原理在你的UI布局有限的情况下，放不下太多的控件的时候，可以考虑用这个隐藏式抽屉。用SlidingDrawer注意两点，一个是android：handle（委托要展开的图片加载Layout配置） 和android：content（要展开的Layout Content），转载请标明出处：

在SlidingDrawerActivity工程下：

一、在com.cn.daming包下的SlidingDrawerMainActivity.java类中的代码：

<span style="font-size: 16px;">package com.cn.daming;

import android.app.Activity;
import android.content.res.Configuration;
import android.os.Bundle;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.SlidingDrawer;

public class SlidingDrawerMainActivity extends Activity {

	private GridView gridView;
	private SlidingDrawer slidingDrawer;
	private ImageView imageView;
	private int[] icons={
		R.drawable.title1, R.drawable.title2,
		R.drawable.title3, R.drawable.title4,
		R.drawable.title5, R.drawable.title6
	};
	
	private String[] items={
		"Phone", "Message", "AddImage", "Music", "Telephone", "SMS"	
	};
	
	@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        gridView = (GridView)findViewById(R.id.mycontent);
        slidingDrawer = (SlidingDrawer)findViewById(R.id.sliding_drawer);
        imageView = (ImageView)findViewById(R.id.my_image);
        MyGridViewAdapter adapter = new MyGridViewAdapter(this, items, icons);
        gridView.setAdapter(adapter);
        slidingDrawer.setOnDrawerOpenListener(new SlidingDrawer.OnDrawerOpenListener() {
			
			public void onDrawerOpened() {
				imageView.setImageResource(R.drawable.right1);
			}
		});
        slidingDrawer.setOnDrawerCloseListener(new SlidingDrawer.OnDrawerCloseListener() {
			
			public void onDrawerClosed() {
				imageView.setImageResource(R.drawable.left1);
			}
		});
    }

	@Override
	public void onConfigurationChanged(Configuration newConfig) {
		super.onConfigurationChanged(newConfig);
	}
}</span>

二、在com.cn.daming包下的MyGridViewAdapter.java类中的代码：

<span style="font-size: 16px;">package com.cn.daming;

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 MyGridViewAdapter extends BaseAdapter{

	private Context context;
	private String[] items;
	private int[] icons;
	
	public MyGridViewAdapter(Context context, String[] items, int[] icons){
		this.context = context;
		this.items = items;
		this.icons = icons;
	}
	
	public int getCount() {
		return items.length;
	}

	public Object getItem(int arg0) {
		return items[arg0];
	}

	public long getItemId(int position) {
		return position;
	}

	public View getView(int position, View convertView, ViewGroup parent) {
		LayoutInflater layoutInflater = LayoutInflater.from(context);
		View view = (View)layoutInflater .inflate(R.layout.grid, null);
		ImageView imageView = (ImageView)view.findViewById(R.id.image_view);
		TextView textview = (TextView)view.findViewById(R.id.text_view);
		imageView.setImageResource(icons[position]);
		textview.setText(items[position]);
		return view;
	}

}
</span>

三、在res包下的layout下的main.xml中的代码：

<span style="font-size: 16px;"><?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
    <TextView
        android:id="@+id/text_view"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dip"
        android:text="@string/hello"
        android:textSize="10pt"
        android:gravity="center"
    />
    <SlidingDrawer
        android:id="@+id/sliding_drawer"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:handle="@+id/layout1"
        android:content="@+id/mycontent"
        android:orientation="horizontal"
    >
        <LinearLayout
           android:id="@id/layout1"
           android:layout_width="35px"
           android:layout_height="fill_parent"
           android:gravity="center"
           android:background="#00000000"
        >
           <ImageView
               android:id="@+id/my_image"
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:src="@drawable/left1"
           />
        </LinearLayout>
        <GridView
            android:id="@id/mycontent"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:paddingTop="20dip"
            android:numColumns="3"
            android:gravity="center"
            android:background="#ff000000"
        />
    </SlidingDrawer>
</RelativeLayout>
</span>

四、在res包下的layout下的grid.xml中的代码：

<span style="font-size: 16px;"><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    >
    <ImageView
        android:id="@+id/image_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="5dip"
    />
    <TextView
        android:id="@+id/text_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="15dip"
    />
</LinearLayout>
</span>

五、在AndroidManifest.xml中的代码：

<span style="font-size: 16px;"><?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.cn.daming"
      android:versionCode="1"
      android:versionName="1.0">
    <uses-sdk android:minSdkVersion="8" />

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".SlidingDrawerMainActivity"
                  android:label="@string/app_name"
                  android:configChanges="orientation|locale">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    </application>
</manifest></span>

补充说明：

也可以设置垂直的隐藏拉抽屉方式，设置SlidingDrawer中的android:orientation="vertical"。

看下截图效果：

修改下res包下的layout下的main.xml文件中的代码：

<span style="font-size: 16px;"><?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
   >
    <TextView
        android:id="@+id/text_view"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dip"
        android:text="@string/hello"
        android:textSize="10pt"
        android:gravity="center"
    />
    <SlidingDrawer
        android:id="@+id/sliding_drawer"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:handle="@+id/layout1"
        android:content="@+id/mycontent"
        android:orientation="vertical"
     >
        <LinearLayout
           android:id="@id/layout1"
           android:layout_width="fill_parent"
           android:layout_height="35px"
           android:gravity="center"
           android:background="#00000000"
        >
           <ImageView
               android:id="@+id/my_image"
               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:src="@drawable/up1"
           />
        </LinearLayout>
        <GridView
            android:id="@id/mycontent"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:paddingTop="20dip"
            android:numColumns="3"
            android:gravity="center"
            android:background="#ff000000"
        />
    </SlidingDrawer>
</RelativeLayout>
</span>

修改grid.xml文件中的代码：

<span style="font-size: 16px;"><?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    >
    <ImageView
        android:id="@+id/image_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="5dip"
        android:layout_marginLeft="27dip"
    />
    <TextView
        android:id="@+id/text_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="15dip"
        android:layout_marginLeft="27dip"
    />
</LinearLayout>
</span>
