PhoneUtils.java是手机功能类，从TelephonyManager中实例化ITelephony并返回，源码如下：

package com.testTelephony;  

  

import java.lang.reflect.Field;  

import java.lang.reflect.Method;  

import com.android.internal.telephony.ITelephony;  

import android.telephony.TelephonyManager;  

import android.util.Log;  

  

public class PhoneUtils {  

    /** 

     * 从TelephonyManager中实例化ITelephony，并返回 

     */  

    static public ITelephony getITelephony(TelephonyManager telMgr) throws Exception {  

        Method getITelephonyMethod = telMgr.getClass().getDeclaredMethod("getITelephony");  

        getITelephonyMethod.setAccessible(true);//私有化函数也能使用  

        return (ITelephony)getITelephonyMethod.invoke(telMgr);  

    }  

      

    static public void printAllInform(Class clsShow) {    

        try {    

            // 取得所有方法    

            Method[] hideMethod = clsShow.getDeclaredMethods();    

            int i = 0;    

            for (; i < hideMethod.length; i++) {    

                Log.e("method name", hideMethod.getName());    

            }    

            // 取得所有常量    

            Field[] allFields = clsShow.getFields();    

            for (i = 0; i < allFields.length; i++) {    

                Log.e("Field name", allFields.getName());    

            }    

        } catch (SecurityException e) {    

            // throw new RuntimeException(e.getMessage());    

            e.printStackTrace();    

        } catch (IllegalArgumentException e) {    

            // throw new RuntimeException(e.getMessage());    

            e.printStackTrace();    

        } catch (Exception e) {    

            // TODO Auto-generated catch block    

            e.printStackTrace();    

        }    

    }    

}  

testTelephony.java是主类，使用PhoneStateListener监听通话状态，以及实现上述4种电话控制功能，源码如下：

package com.testTelephony;  

  

import android.app.Activity;  

import android.os.Bundle;  

import android.telephony.PhoneStateListener;  

import android.telephony.TelephonyManager;

import android.widget.RadioGroup;  

import android.widget.ToggleButton;  

  

public class testTelephony extends Activity {  

    /** Called when the activity is first created. */  

    RadioGroup rg;//来电操作单选框  

    ToggleButton tbtnRadioSwitch;//Radio开关  

    ToggleButton tbtnDataConn;//数据连接的开关  

    TelephonyManager telMgr;  

    CallStateListener stateListner;  

    int checkedId=0;  

    @Override  

    public void onCreate(Bundle savedInstanceState) {  

        super.onCreate(savedInstanceState);  

        setContentView(R.layout.main);  

          

        telMgr= (TelephonyManager)getSystemService(TELEPHONY_SERVICE);  

        telMgr.listen(new CallStateListener(), CallStateListener.LISTEN_CALL_STATE);  

          

        PhoneUtils.printAllInform(TelephonyManager.class);  

          

        rg = (RadioGroup)findViewById(R.id.rGrpSelect);  

        rg.setOnCheckedChangeListener(new CheckEvent());  

        tbtnRadioSwitch=(ToggleButton)this.findViewById(R.id.tbtnRadioSwitch);  

        tbtnRadioSwitch.setOnClickListener(new ClickEvent());  

        try {  

            tbtnRadioSwitch.setChecked(PhoneUtils.getITelephony(telMgr).isRadioOn());  

        }  catch (Exception e) {  

            Log.e("error",e.getMessage());  

        }  

        tbtnDataConn=(ToggleButton)this.findViewById(R.id.tbtnDataConn);  

        tbtnDataConn.setOnClickListener(new ClickEvent());  

        try {  

            tbtnDataConn.setChecked(PhoneUtils.getITelephony(telMgr).isDataConnectivityPossible());  

        }  catch (Exception e) {  

            Log.e("error",e.getMessage());  

        }  

    }
