IP拨号器的实现，broadcast receives广播接收器

一、广播接受者：
1、权限设置

<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>

2、action设置

<receiver     android:name=".CallReceiver">    <intent-filter>    <action android:name="android.intent.action.NEW_OUTGOING_CALL"    />    </intent-filter></receiver>

3、广播接受者代码

public void onReceive(Context context, Intent intent) {        // TODO: This method is called when the BroadcastReceiver is receiving        // an Intent broadcast.        System.out.println("拨号器接受信息");        //throw new UnsupportedOperationException("Not yet implemented");        String number = getResultData();        System.out.println(number);        SharedPreferences sp = context.getSharedPreferences("ip",context.MODE_PRIVATE);        String ipNumber = sp.getString("ipNumber","");        number = ipNumber + number;        setResultData(number);    }

二、IP拨号器代码

public void click(View v){        EditText et = (EditText) findViewById(R.id.et);        SharedPreferences sp = getSharedPreferences("ip",MODE_PRIVATE);        sp.edit().putString("ipNumber",et.getText().toString()).commit();    }
