布局文件中定义一下UI,虽然没什么UI.....

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:orientation="vertical"    android:layout_height="match_parent"    tools:context=".MainActivity" >    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/hello_world" /><EditText     android:id="@+id/et_number"    android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:inputType="phone"    /><Button     android:layout_height="wrap_content"    android:layout_width="fill_parent"    android:text="保存ip号码"    android:onClick="save"    /></LinearLayout >

在mainactivity中实现部分代码

package com.wzw.ipdial;import android.app.Activity;import android.content.SharedPreferences;import android.content.SharedPreferences.Editor;import android.os.Bundle;import android.text.TextUtils;import android.view.View;import android.widget.EditText;import android.widget.Toast;public class MainActivity extends Activity {private EditText etNumber;private SharedPreferences sp;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);etNumber=(EditText) findViewById(R.id.et_number);sp=getSharedPreferences("config", MODE_PRIVATE);}public void save(View v){String ipnumber=etNumber.getText().toString().trim();if(TextUtils.isEmpty(ipnumber)){Toast.makeText(this, "清除IP号码成功", 0).show();}else{Toast.makeText(this, "设置IP号码成功", 0).show();}Editor editor=sp.edit();editor.putString("ipnumber", ipnumber);editor.commit();}}

新建一个类继承广播接收者

package com.wzw.ipdial;/** * 定义一个收音机 */import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.content.SharedPreferences;import android.util.Log;public class Ipdial extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubString number=getResultData();SharedPreferences sp=context.getSharedPreferences("config", context.MODE_PRIVATE);String ipnumber=sp.getString("ipnumber", "");setResultData(ipnumber+number);}}

清单文件中给权限

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.wzw.ipdial"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="8"        android:targetSdkVersion="17" />    <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity            android:name="com.wzw.ipdial.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>        <!-- 设置广播接受者，并指定接收拨打电话的动作 -->        <receiver android:name="com.wzw.ipdial.Ipdial">            <intent-filter >                <action android:name="android.intent.action.NEW_OUTGOING_CALL"/>                </intent-filter>        </receiver>    </application></manifest>
