Android 实现分享功能代码

首先新建share.xml布局文件 
[html]  
<?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" >  
  
    <Button  
        android:id="@+id/share"  
        android:layout_width="fill_parent"  
        android:layout_height="wrap_content"  
        android:text="分享" />  
  
</LinearLayout>    
然后是新建Activity 
[java]  
/** 
 * ShareActivity.java 
 * 版权所有(C) 2012  
 * 创建:cuiran 2012-10-17 上午9:23:05 
 */  
package com.cayden.citygirl.activity;  
  
import android.app.Activity;  
import android.content.Intent;  
import android.os.Bundle;  
import android.view.View;  
import android.widget.Button;  
  
/** 
 * TODO 
 * @author cuiran 
 * @version TODO 
 */  
public class ShareActivity extends Activity {  
  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        // TODO Auto-generated method stub  
        super.onCreate(savedInstanceState);  
          
        setContentView(R.layout.share);  
          
        Button share=(Button)this.findViewById(R.id.share);  
        share.setOnClickListener(new View.OnClickListener() {  
              
            @Override  
            public void onClick(View v) {  
                Intent intent=new Intent(Intent.ACTION_SEND);    
                intent.setType("image/*");    
                intent.putExtra(Intent.EXTRA_SUBJECT, "Share");    
                intent.putExtra(Intent.EXTRA_TEXT, "I have successfully share my message through my app (分享自city丽人馆)");    
                 
                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);    
                startActivity(Intent.createChooser(intent, getTitle()));    
                  
            }  
        });  
          
    }
