短信监控器

-------------------------------------------------------短信监控---------------------------------------------------------------------------------

一、---框架---

（1）新建SmsListenerReceiver继承BroadcastReceiver类

（2）获取短信的信息的内容和发送者信息

（3）配置Receiver，以及action，打开短信权限

二、---布局创建---

短信监控器的显示结果如下，当有短信到来的时候打印一个吐司

三、---代码---

（1）如下是Rceiver的代码

package com.iigt.smslistener;

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

public class SmsListenerReceiver extends BroadcastReceiver{

@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Object[] objects = (Object[]) intent.getExtras().get("pdus");

for(Object pdu : objects){
//获取smsMessage的实例
SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) pdu);

//获取短信的发送内容
String messageBody = smsMessage.getMessageBody();

//获取短信的发送者
String originatingAddress = smsMessage.getOriginatingAddress();

//吐司处理
System.out.println("body:"+messageBody+"---"+originatingAddress);
Toast.makeText(context, originatingAddress+"发送的内容为:"+messageBody, Toast.LENGTH_LONG).show();

}
}

}

（2）如下是配置文件的源代码

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.iigt.smslistener"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.iigt.smslistener.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

<receiver android:name="com.iigt.smslistener.SmsListenerReceiver">
<intent-filter >
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
</application>
</manifest>

包括短信权限的打开和action代码的执行

-------------------------------------------------------对话框--------------------------------------------------------------------------

一、---效果---

如下是普通选型框：



下面这个是 单选框：

二、---代码---

package com.iigt.dialog;

import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.AlertDialog.Builder;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.view.Menu;
import android.view.View;
import android.widget.Toast;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}

//点击普通对话框
public void click1(View v){
AlertDialog.Builder builder = new Builder(this);
builder.setTitle("警告信息");
builder.setMessage("我是普通对话框");
builder.setPositiveButton("同意", new OnClickListener() {

public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "这家伙居然同意了", 1).show();
}
});

builder.setNegativeButton("否定", new OnClickListener() {

public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "这家伙居然否定了", 1).show();
}
});

// 最后一步一定要记得 show出来
builder.show();
}

// 下面是单选的对话框
public void click2(View v){
AlertDialog.Builder builder = new Builder(this);
builder.setTitle("这个是单选框");
final String items[] = {"苹果", "鸭梨", "橘子", "西红柿", "香蕉"};
builder.setSingleChoiceItems(items, -1, new OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
// 取出点中的条目
String item = items[which];
Toast.makeText(getApplicationContext(), item, 1).show();
// 关闭当前对话框
dialog.dismiss();
}
});
// 最后一步一定要记得 show出来
builder.show();
}
}

和上面的类似，如下是一个多选对话款和进度条对话框：



如下是进度条对话框：



以下是上面两个对话框的代码：

// 点击按钮 弹出一个多选对话框
public void click3(View v) {
// 构建AlertDialog
AlertDialog.Builder builder = new Builder(this);
builder.setTitle("请选择您喜欢吃的水果");
final String items[] = { "榴莲", "苹果", "葡萄", "香蕉", "黄瓜", "火龙果", "荔枝" };
final boolean[] checkedItems = { true, false, false, false, false,
false, true };
builder.setMultiChoiceItems(items, checkedItems,
new OnMultiChoiceClickListener() {

@Override
public void onClick(DialogInterface dialog, int which,
boolean isChecked) {

}
});
builder.setPositiveButton("确定", new OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {

StringBuffer sb = new StringBuffer();
// [1]把你选中的水果给取出来
for (int i = 0; i < checkedItems.length; i++) {
if (checkedItems[i]) {
// 就证明是选中的
String fruit = items[i];
sb.append(fruit + " ");

}

}

Toast.makeText(getApplicationContext(), sb.toString(), 1)
.show();
// 关闭对话框
dialog.dismiss();

}
});

// 最后一步一定要记得 show出来
builder.show();

}

//进度条对话框
public void click4(View v) {

//与进度相关的控件都可以直接在子线程更新ui
final ProgressDialog dialog = new ProgressDialog(this);
dialog.setTitle("正在玩命加载ing");
dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
dialog.show();
//设置进度条的最大值
dialog.setMax(100);
new Thread(){public void run() {
for (int i = 0; i <= 100; i++) {
//设置当前的进度

SystemClock.sleep(50);//睡眠50毫秒
dialog.setProgress(i);
}
//关闭对话框
dialog.dismiss();

};}.start();

}
}
