再此加上文件目录

MainActivity代码

 package com.example.call;

import java.lang.reflect.InvocationTargetException;

public class MainActivity extends Activity {

    private Method method;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        setContentView(R.layout.activity_main);
        //通过反射机制得到类

        try {
            //得到类

            //得到方法
            method = clazz.getMethod("getService", String.class);
            //调用方法(静态方法不用传对象)
            IBinder iBinder = (IBinder) method.invoke(null, Context.TELEPHONY_SERVICE);
            //得到远程服务接口
            ITelephony telePhone = ITelephony.Stub.asInterface(iBinder);
            //打电话功能
            telePhone.call("15686207622");
        } catch (ClassNotFoundException e) {
            //没有找到这个类

            e.printStackTrace();

            e.printStackTrace();
        } catch (RemoteException e) {

        }

    }
