android实习程序 ——短信

来源：互联网发布：alt 左键 ubuntu 编辑：程序博客网时间：2024/06/08 06:22

短信格式：

电话号码：（3/4位）区号 + （7/8）号码

中国电话号码难以处理

短信的uri以content://sms开头

短信

body //内容

type //类型（别人发给我或发给别人）1：接受，2：发出（除1以外的）

date //时间

id： //可能不准确

Thread_id//准确，短信会话的分组依据

read() //0表示未读，1表示已读

address //地址：电话号码

O2O ：线上to线下

中国工商银行 2303亿

添加滚动条

<ScrollViewxmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="fill_parent"

android:layout_height="fill_parent">

添加在最外层

滚动条的高度

短信显示的高度

android的屏幕也是有坐标的

以左上角为原点，向右为X轴的正方向，向下为Y轴的正方向

滚动条的高度最多只能是屏幕的高度，但是短信显示的高度可以超出屏幕

主线程也可称为UI线程，与界面的响应度有关

优先度从大到小的排列的线程

Activity运行在主线程中，创建也是这里面

执行oncreate（）、onstart（）、onresume（）

查询看看用户是否有ontouch（）事件：触摸事件也为主线程

执行handler、service

主线程忙，须有优先度的排列

Ctrl + Shift + F ：java 中的格式化

注意把搜狗输入法关掉，搜狗输入法会占用该快捷键

阿里云的 android SDK

1、短信界面

2、在Log中查看短信

3、加滚动条的从下往上显示短信

1、短信界面

2、在Log中查看短信

SmsActivity.java

package cpm.tarena.Phone;

import android.app.Activity;

import android.content.ContentResolver;

import android.database.Cursor;

import android.net.Uri;

import android.os.Bundle;

import android.util.Log;

public class SmsActivity extends Activity{

ContentResolver mContentResolver;

@Override

protected void onCreate(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

mContentResolver = this.getContentResolver();

//读出每个电话号码，对应的最新一条短信//准备Uri 调用数据

Uri smsTitle =Uri.parse("content://mms-sms/conversations");

Cursor mCursor = mContentResolver.query(smsTitle, null, null, null, "date desc");

String[] arrcols = mCursor.getColumnNames();

while(mCursor.moveToNext()){

for(int i = 0; i<arrcols.length; i++){

Log.i("sms_data", arrcols[i]+":"+mCursor.getString(i));

}

Log.i("sms_data", "-------------------------");

}

mCursor.close();

//查询Thread_id对应的短信

Uri smsdetaildata = Uri.parse("content://sms");

mCursor =mContentResolver.query(smsdetaildata, null, "thread_id=1", null, "date desc");

arrcols = mCursor.getColumnNames();

while(mCursor.moveToNext()){

for(int i = 0; i<arrcols.length; i++){

Log.i("sms_detaildata", arrcols[i]+":"+mCursor.getString(i));

}

Log.i("sms_detaildata", "************************");

}

mCursor.close();

}

在manifest 中修改name的为.SmsActivity

创建sms_data 和 sms_detaildata 分别查看

3、加滚动条的从下往上显示短信
