android實習程序 ——短信

短信格式：

電話號碼：（3/4位）區號 + （7/8）號碼

中國電話號碼難以處理

短信的uri以content://sms開頭

短信

body //內容

type //類型（別人發給我或發給別人）1：接受，2：發出（除1以外的）

date //時間

id： //可能不準確

Thread_id//準確，短信會話的分組依據

read() //0表示未讀，1表示已讀

address //地址：電話號碼

O2O ：線上to線下

添加滾動條

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

android:layout_width="fill_parent"

android:layout_height="fill_parent">

添加在最外層

滾動條的高度

短信顯示的高度

android的屏幕也是有座標的

以左上角爲原點，向右爲X軸的正方向，向下爲Y軸的正方向

滾動條的高度最多隻能是屏幕的高度，但是短信顯示的高度可以超出屏幕

主線程也可稱爲UI線程，與界面的響應度有關

優先度從大到小的排列的線程

Activity運行在主線程中，創建也是這裏面

執行oncreate（）、onstart（）、onresume（）

查詢看看用戶是否有ontouch（）事件：觸摸事件也爲主線程

執行handler、service

主線程忙，須有優先度的排列

Ctrl + Shift + F ：java 中的格式化

注意把搜狗輸入法關掉，搜狗輸入法會佔用該快捷鍵

阿里雲的 android SDK

1、短信界面

2、在Log中查看短信

3、加滾動條的從下往上顯示短信

1、短信界面

sms_detail_layout.xml

===================================================-

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();

//讀出每個電話號碼，對應的最新一條短信//準備Uri 調用數據

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();

//查詢Thread_id對應的短信

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的爲.SmsActivity

創建sms_data 和 sms_detaildata 分別查看

=================================================================

3、加滾動條的從下往上顯示短信
