利用广播实现ip拨号——示例

1、创建activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="请输入设置的ip电话号码" />

    <EditText
        android:id="@+id/editText1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="phone" >
    </EditText>

    <Button
        android:id="@+id/button1"
        android:onClick="click"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="确定" />

</LinearLayout>

2、创建MainActivity.java类

package com.example.ipdail;

import android.os.Bundle;
import android.app.Activity;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends Activity {

    private EditText et_number;
    private SharedPreferences sp;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        et_number = (EditText) findViewById(R.id.editText1);
        
        sp=getSharedPreferences("config", MODE_PRIVATE);
        String ipNumber=sp.getString("number", "");
        et_number.setText(ipNumber);

    }

    public void click(View view) {
        Editor editor=sp.edit();
        editor.putString("number", et_number.getText().toString().trim());
        editor.commit();
        Toast.makeText(this, "设置完成", 0).show();
        
    }

}

3、编写OutCallReceiver.java类

/**
 * 
 */
package com.example.ipdail;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.graphics.AvoidXfermode.Mode;

/**
 * @author hyzhou
 *
 * 2013-12-5
 */
public class OutCallReceiver extends BroadcastReceiver {

    /* (non-Javadoc)
     * @see android.content.BroadcastReceiver#onReceive(android.content.Context, android.content.Intent)
     */
    @Override
    public void onReceive(Context context, Intent intent) {
        // 获得外拨电话号码
        String number=getResultData();
        SharedPreferences sp=context.getSharedPreferences("config",context.MODE_PRIVATE);
        String ipnumber=sp.getString("number", "");
        
        String newnumber=ipnumber+number;
        setResultData(newnumber);
        
    }

}

4、注册广播AndroidManifest.xml

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

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />
    <!-- 添加外拨权限 -->>
    <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.example.ipdail.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>
    <!-- 定义一个广播接收者 new 设置action -->
        <receiver android:name="com.example.ipdail.OutCallReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
            </intent-filter>
        </receiver>
    </application>

</manifest>
