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;
@Override
protected 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 {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
String 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"

android:versionCode="1"

<!-- 设置广播接受者,并指定接收拨打电话的动作 -->
