Android打电话，挂电话

100%运行通过，有图有真相！！！

Android打电话，挂电话_第1张图片

第一步：布局文件

第二步：权限

<?xml version="1.0" encoding="utf-8"?>

第三步：实现代码

package com.example.crazycall;import java.lang.reflect.InvocationTargetException;import java.lang.reflect.Method;import android.net.Uri;import android.os.Bundle;import android.os.RemoteException;import com.android.internal.telephony.ITelephony;import android.app.Activity;import android.app.Service;import android.content.Intent;import android.telephony.TelephonyManager;import android.view.Menu;import android.view.View;import android.widget.Button;import android.widget.EditText;import android.widget.Toast;public class MainActivity extends Activity {private Button start_btn;private Button end_btn;private EditText phone_number;private ITelephony iTelephony;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);start_btn=(Button)findViewById(R.id.start_btn);end_btn=(Button)findViewById(R.id.end_btn);phone_number=(EditText)findViewById(R.id.phone_number);start_btn.setOnClickListener(new Button.OnClickListener() {@Overridepublic void onClick(View arg0) {// TODO Auto-generated method stubString phonenumber=phone_number.getText().toString();callPhoneNumber(phonenumber);}});end_btn.setOnClickListener(new Button.OnClickListener() {@Overridepublic void onClick(View arg0) {// TODO Auto-generated method stubclosePhone();}});}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}private void callPhoneNumber(String string) {if (string.trim().length()!=0) {Intent intent=new Intent(Intent.ACTION_CALL,Uri.parse("tel:"+string));startActivity(intent);} else {Toast.makeText(MainActivity.this, "不能为空", Toast.LENGTH_LONG).show();}}private void closePhone() {try {getTelephony();iTelephony.endCall();} catch (RemoteException e) {// TODO: handle exceptione.printStackTrace();}}public void getTelephony() {TelephonyManager telephonyManager=(TelephonyManager)getSystemService(Service.TELEPHONY_SERVICE);Class class1=TelephonyManager.class;Method getITelephonyMethod=null;try {getITelephonyMethod=class1.getDeclaredMethod("getITelephony", (Class[])null);getITelephonyMethod.setAccessible(true);} catch (SecurityException e) {// TODO: handle exceptione.printStackTrace();} catch (NoSuchMethodException e) {// TODO: handle exceptione.printStackTrace();}try {iTelephony=(ITelephony)getITelephonyMethod.invoke(telephonyManager, (Object[])null);} catch (IllegalArgumentException e) {// TODO: handle exceptione.printStackTrace();} catch (IllegalAccessException e) {// TODO: handle exceptione.printStackTrace();} catch (InvocationTargetException e) {// TODO: handle exceptione.printStackTrace();}}}

注意：挂电话需要用到系统的ITelephony类，但是Google从Android2.1 SDK版本后，屏蔽了ITelephony类，在此附上此类代码，自行创建记事本，然后改文件名和扩展名。
