ip拨号器demo----BroadcastReceiver

新建一个class类，继承BroadcastReceiver

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class CallReceiver extends BroadcastReceiver {

	//收到广播时调用
	public void onReceive(Context context, Intent intent) {
		// 取出广播中的号码
		String number = getResultData();
		//添加新号码
		String newNumber = "17951" +number;
		//把修改后的号码放到广播中
		setResultData(newNumber);
	}

}

清单文件注册，并添加权限

            android:name=".MainActivity"
            android:label="@string/app_name" >
