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);
    }
}
