android的分享功能

网上找了些例子 ，顺便写了个简单分享 留着以后自己看

package com.peng.share;

import java.util.List;

import android.app.Activity;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

public class ShareActivity extends Activity {
   
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
    
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
    // TODO Auto-generated method stub
    menu.addSubMenu(0, 0, 0, "分享");
    menu.addSubMenu(1, 1, 1, "查询");
    return true;
    }
    
    
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
    // TODO Auto-generated method stub
    switch (item.getItemId()) {
case 0:
Intent intent=new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_SUBJECT, "分享");
intent.putExtra(Intent.EXTRA_TEXT, "I would like to share this with you...");
startActivity(Intent.createChooser(intent, getTitle()));
return true;
case 1:
List list = getShareTargets();
break;
}
    return false;
    }
    
   
    private List getShareTargets(){
    Intent intent=new Intent(Intent.ACTION_SEND,null);
    intent.addCategory(Intent.CATEGORY_DEFAULT);
    intent.setType("text/plain");

    PackageManager pm=this.getPackageManager();

    return pm.queryIntentActivities(intent,
    PackageManager.COMPONENT_ENABLED_STATE_DEFAULT);
    }

}
