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] 
/**

 * 版权所有(C) 2012

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()));   
                 
            } 
        }); 
         
    }
