短信的收发简单Demo
短信的发送：
发送短信相当的简单，只需要几行代码，如下：
参数phoneNumber和MsgStr均是String类型，表示接收方的电话号码和短信内容

SmsManager sms = SmsManager.getDefault();
PendingIntent pi = PendingIntent.getBroadcast(this, 0, new Intent(), 0);
sms.sendTextMessage(phoneNumber, null, MsgStr, pi, null);

短信的接收：
MainActivity:

package com.amaker.sms;

import android.app.Activity;
import android.content.IntentFilter;
import android.os.Bundle;

public class MainActivity extends Activity {
    //接收短信的action
	public static final String MY_ACTION = "android.provider.Telephony.SMS_RECEIVED";
	MyReceiver receiver = new MyReceiver();
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
    
    
   /**
    * 注册接收短信的广播接收器
    * 这里采用了动态的方式注册，也可以在AndroidManifest.xml里静态注册
    */
    
    @Override
    protected void onResume() {
    	super.onResume();
    	
    	IntentFilter filter = new IntentFilter();
    	filter.addAction(MY_ACTION);
    	registerReceiver(receiver, filter);
    }
    /**
     * 取消接收短信的广播接收器
     */
    @Override
    protected void onPause() {
    	super.onPause();
    	unregisterReceiver(receiver);
    }
}

MyReceiver:

package com.amaker.sms;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.Toast;

public class MyReceiver extends BroadcastReceiver {

	@Override
	public void onReceive(Context context, Intent intent) {
		SmsMessage sm;
		Bundle bundle = intent.getExtras();
		Object[] pdus = (Object[]) bundle.get("pdus");
		SmsMessage[] messages = new SmsMessage[pdus.length];
		
		if(bundle!=null){
			for (int i = 0; i < pdus.length; i++) {
				messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
			}
		}
		for(SmsMessage currentMessage:messages){
			sm = currentMessage;
			
			String number = sm.getDisplayOriginatingAddress();
			String content = sm.getDisplayMessageBody();
			
			Toast.makeText(context, number+":"+content, Toast.LENGTH_LONG).show();
		}
	}

}

ubuntu-11.10-server-i386学习笔记-网络基本配置
1. 静态ＩＰ地址配置

配置文件路径：/etc/network/interfaces



auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.0.24
netmask 255.255.255.0
network 192.168.0.0
gateway 192.168.0.1
dns-nameservers 192.168.0.1  【不需要】

配置好后，重新启动网卡服务：sudo /etc/init.d/networking restart



  查看IP地址： ifconifg



检查网络通不通：ping 222.221.200.68（随便找个公网地址ping、ping测试哈）





配置DNS域名解析

vi /etc/resolv.conf





至此网络常见配置完毕

圆角图片的处理和圆角按钮的动画

当我们需要圆角的时候，调用这个方法，第一个参数是传入需要转化成圆角的图片，第二个参数是圆角的度数，数值越大，圆角越大

下面举个例子，有一个LinearLayout，想把它的背景图片设置成圆角

布局文件main.xml

1.<?xml version="1.0" encoding="utf-8"?>

2.<LinearLayout

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

4. android:id="@+id/layout" android:orientation="vertical"

5. android:layout_width="wrap_content"

6. android:layout_height="wrap_content">

7.</LinearLayout>
.mInflater = LayoutInflater.from(this);



Drawable drawable = getResources().getDrawable(R.drawable.icon);

BitmapDrawable bitmapDrawable = (BitmapDrawable) drawable;

Bitmap bitmap = bitmapDrawable.getBitmap();


View view = mInflater.inflate(

R.layout.share_xiaohua_revert_lv_item_top, null);

ImageView mImageView = (ImageView) view

.findViewById(R.id.lv_xiaohua_image);

mImageView.setImageBitmap(toRoundCorner(bitmap, 30));
