手机照片上传

首先写好一个专门用于封装提交的信息的处理类

 

FormFile.java

package com.cnjmwl.util;

public class FormFile
{
  /* 上传文件的数据 */  
  private byte[] data;  
  /* 文件名称 */  
  private String filname;  
  /* 表单字段名称*/  
  private String formname;  
  /* 内容类型 */  
  private String contentType = "text/plain"; //需要查阅相关的资料  

  public FormFile(String filname, byte[] data, String formname, String contentType) {  
    this.data = data;  
    this.filname = filname;  
    this.formname = formname;  
    if(contentType!=null) this.contentType = contentType;  
  }  

  public byte[] getData() {  
    return data;  
  }  

  public void setData(byte[] data) {  
    this.data = data;  
  }  

  public String getFilname() {  
    return filname;  
  }  

  public void setFilname(String filname) {  
    this.filname = filname;  
  }  

  public String getFormname() {  
    return formname;  
  }  

  public void setFormname(String formname) {  
    this.formname = formname;  
  }  

  public String getContentType() {  
    return contentType;  
  }  

  public void setContentType(String contentType) {  
    this.contentType = contentType;  
  }  
}

  然后写android客户端提交到的方法

  String actionURl="http://192.168.1.79:6888/jmcustomer/placeOrderServlet";

 		   //String actionURl=HttpUtil.BASE_URL+"new";
		   Map<String, String> params=new HashMap<String, String>();
		   
		   //传个用户名
		   params.put("username", this.getIntent().getStringExtra("username"));
		   params.put("orderdesc", StringUtil.utf8ToUnicode(orderdesc.getText().toString()));
		   String contentType = "image/JPEG";
		   
		   
		 File file =new File("/data/data/test.jpg");
		byte[] buffer = new byte[1024];
		int len = -1;
		ByteArrayOutputStream outStream = new ByteArrayOutputStream();
		 BufferedInputStream bufferedInputStream;
		try {
			bufferedInputStream = new BufferedInputStream(new FileInputStream(file));
			while ((len = bufferedInputStream.read(buffer)) != -1)
			{
				outStream.write(buffer, 0, len);
			}
			 data = outStream.toByteArray();
			outStream.close();
			bufferedInputStream.close();
			
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
		
		//获取用户编辑照片的文件名
	    String   photoName=fileName.getText().toString();
	    if(photoName==null||photoName.trim().equals("")){
	    	photoName="default";
	    }
		// FormFile[] files=new FormFile[]{new FormFile("test.jpg",data,"file1",contentType)};
		 FormFile[] files=new FormFile[]{new FormFile(photoName+".jpg",mContent,"file1",contentType)};
		String result= post(actionURl, params, files);
		if(result.equals("1")){
			showAlert("提交成功！");
		}else{
			showAlert("提交失败！");
		}

【转】PendingIntent和Intent的区别

Notification n = new Notification(R.drawable.face_1, "Service启动", System.currentTimeMillis());  
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, TServiceHolder.class), 0);  
n.setLatestEventInfo(this, "任务标题", "任务内容", contentIntent);  
nManager.notify(NOTIFICATION_ID, n); // 任务栏启动 

PendingIntent和Intent的区别：An Intent is something that is used right now; a PendingIntent is something that may create an Intent in the future. You will use a PendingIntent with Notifications, AlarmManager, etc.
1. GSM网络中android发送短信示例
（1）代码节选

String msg ="你好，美女";  
String number = "135****6784";  
SmsManager sms = SmsManager.getDefault();  
  
PendingIntent pi = PendingIntent.getBroadcast(SmsActivity.this,0,new Intent(...),0);  
sms.sendTextMessage(number, null, msg, pi, null);  
Toast.makeText(SmsActivity.this,"发送成功",Toast.LENGHT_LONG).show();  

2）代码解释
      PendingIntent就是一个Intent的描述，我们可以把这个描述交给别的程序，别的程序根据这个描述在后面的别的时间做你安排做的事情 （By giving a PendingIntent to another application, you are granting it the right to perform the operation you have specified as if the other application was yourself，就相当于PendingIntent代表了Intent）。本例中别的程序就是发送短信的程序，短信发送成功后要把intent广播出去 。
      函数SmsManager.sendTextMessage(String destinationAddress, String scAddress, String text, PendingIntent sentIntent, PendingIntent deliveryIntent)中参数解释：
      1）PendingIntent sentIntent：当短信发出时，成功的话sendIntent会把其内部的描述的intent广播出去，否则产生错误代码并通过android.app.PendingIntent.OnFinished进行回调，这个参数最好不为空，否则会存在资源浪费的潜在问题；
      2）PendingIntent deliveryIntent：是当消息已经传递给收信人后所进行的PendingIntent广播。
      查看PendingIntent 类可以看到许多的Send函数，就是PendingIntent在进行被赋予的相关的操作。
