android 监听去电实现ip拨号广播接收者

利用广播实现ip拨号

布局文件：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"              android:orientation="vertical"              android:layout_width="fill_parent"              android:layout_height="fill_parent"        >    <TextView            android:layout_width="fill_parent"            android:layout_height="wrap_content"            android:text="请输入ip号码前缀"            />            <EditText            android:id="@+id/phoneNum"            android:inputType="number"            android:layout_width="match_parent"            android:layout_height="wrap_content"/>    <Button            android:text="保存"            android:onClick="click"            android:layout_width="wrap_content"            android:layout_height="wrap_content"/></LinearLayout>

activity：

package com.heyiyong.ipdial;import android.app.Activity;import android.content.Context;import android.content.SharedPreferences;import android.os.Bundle;import android.view.View;import android.widget.EditText;public class MyActivity extends Activity {    EditText editText;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        this.editText = (EditText) findViewById(R.id.phoneNum);        SharedPreferences sharedPreferences = getSharedPreferences("config", Context.MODE_PRIVATE);        String number = sharedPreferences.getString("number", "");        editText.setText(number);    }    public void click(View view) {        SharedPreferences sharedPreferences = getSharedPreferences("config", Context.MODE_PRIVATE);        SharedPreferences.Editor editor = sharedPreferences.edit();        editor.putString("number", editText.getText().toString());        editor.commit();    }}

接收者：

package com.heyiyong.ipdial;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.content.SharedPreferences;/** * Created by Administrator on 14-1-2. */public class DialReceiver extends BroadcastReceiver {    public void onReceive(Context context, Intent intent) {        String currentNumber = getResultData();        //获取设置的ip号前缀        SharedPreferences sharedPreferences = context.getSharedPreferences("config", Context.MODE_PRIVATE);        String ipNumber = sharedPreferences.getString("number","");        String newNumber = ipNumber+currentNumber;        setResultData(newNumber);    }}

清单文件：
