android 实现分享功能

1、新建share.xml布局文件

<?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>

2、新建ShareActivity

/**

 * 创建:cuiran 2015-7-29

package com.share.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 (By Dengao)");  

                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(Intent.createChooser(intent, getTitle()));  

            }
        });

    }

}
