类型===========================================

标准模式=====

Intent intent = new Intent(Intent.ACTION_SEND); //启动分享发送的属性
intent.setType("text/plain"); // 分享发送的数据类型
String msg = "推荐给大家";
intent.putExtra(Intent.EXTRA_TEXT, msg); // 分享的内容
activity.startActivity(Intent.createChooser(intent,"选择分享"));// 目标应用选择对话框的标题 
标准模式========================================

举例说明======

1.发送文本

                  Intent sendIntent = new Intent();  sendIntent.setAction(Intent.ACTION_SEND);

                  sendIntent.putExtra(Intent.EXTRA_TEXT,"Mirror is a good application, let's share it");          sendIntent.setType("text/*");

                  startActivity(sendIntent);

2.发送图片

                  Intent sendIntent = new Intent();  sendIntent.setAction(Intent.ACTION_SEND);  File f = new File(Environment.getExternalStorageDirectory() + "/q.png");          Uri u = Uri.fromFile(f);

                  sendIntent.putExtra(Intent.EXTRA_STREAM, u);

                  sendIntent.setType("image/png");

                  startActivity(sendIntent);

举例说明========================================
特例===========
/** * 从Assets中读取图片 */private Bitmap getImageFromAssetsFile(String fileName) {Bitmap image = null;AssetManager am = getResources().getAssets();try {InputStream is = am.open(fileName);image = BitmapFactory.decodeStream(is);is.close();} catch (IOException e) {e.printStackTrace();}return image;}
从android eclipse工程中获取图片资源
注意： 调用系统默认分享，不能传工程中的图片资源，只能是再手机上存储的图片
特例===============================================
