下面教你如何去实现android自动接听和挂断电话功能。代码如下:
添加权限<uses-permission android:name="android.permission.CALL_PHONE"/><uses-permission android:name="android.permission.MODIFY_PHONE_STATE"/>main.xml<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"androidrientation="vertical" android:layout_width="fill_parent"android:layout_height="fill_parent"><RadioGroup android:layout_height="wrap_content"android:layout_width="fill_parent" android:id="@+id/rGrpSelect"><RadioButton android:layout_height="wrap_content"android:layout_width="fill_parent" android:id="@+id/rbtnAutoAccept"android:text="所有来电自动接听"></RadioButton><RadioButton android:layout_height="wrap_content"android:layout_width="fill_parent" android:id="@+id/rbtnAutoReject"android:text="所有来电自动挂断"></RadioButton></RadioGroup><ToggleButton android:layout_height="wrap_content"android:layout_width="fill_parent" android:id="@+id/tbtnRadioSwitch"android:textOn="Radio已经启动" android:textOff="Radio已经关闭"android:textSize="24dip" android:textStyle="normal"></ToggleButton><ToggleButton android:layout_height="wrap_content"android:layout_width="fill_parent" android:id="@+id/tbtnDataConn"android:textSize="24dip" android:textStyle="normal" android:textOn="允许数据连接"android:textOff="禁止数据连接"></ToggleButton></LinearLayout>
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 blocke.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.util.Log;import android.view.View;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;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);telMgr= (TelephonyManager)getSystemService(TELEPHONY_SERVICE);100telMgr.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());}}/*** 来电时的操作* @author GV**/public class CheckEvent implements RadioGroup.OnCheckedChangeListener{@Overridepublic void onCheckedChanged(RadioGroup group, int checkedId) {testTelephony.this.checkedId=checkedId;}}/*** Radio和数据连接的开关* @author GV**/public class ClickEvent implements View.OnClickListener{@Overridepublic void onClick(View v) {if (v == tbtnRadioSwitch) {try {PhoneUtils.getITelephony(telMgr).setRadio(tbtnRadioSwitch.isChecked());} catch (Exception e) {Log.e("error", e.getMessage());}}else if(v==tbtnDataConn){try {if(tbtnDataConn.isChecked())PhoneUtils.getITelephony(telMgr).enableDataConnectivity();else if(!tbtnDataConn.isChecked())PhoneUtils.getITelephony(telMgr).disableDataConnectivity();} catch (Exception e) {Log.e("error", e.getMessage());}}}}/*** 监视电话状态* @author GV**/public class CallStateListener extends PhoneStateListener {@Overridepublic void onCallStateChanged(int state, String incomingNumber) {if(state==TelephonyManager.CALL_STATE_IDLE)//挂断{Log.e("IDLE",incomingNumber);}else if(state==TelephonyManager.CALL_STATE_OFFHOOK)//接听{Log.e("OFFHOOK",incomingNumber);}else if(state==TelephonyManager.CALL_STATE_RINGING)//来电{if(testTelephony.this.checkedId==R.id.rbtnAutoAccept){try {//需要<uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />PhoneUtils.getITelephony(telMgr).silenceRinger();//静铃PhoneUtils.getITelephony(telMgr).answerRingingCall();//自动接听} catch (Exception e) {Log.e("error",e.getMessage());}}else if(testTelephony.this.checkedId==R.id.rbtnAutoReject){try {PhoneUtils.getITelephony(telMgr).endCall();//挂断PhoneUtils.getITelephony(telMgr).cancelMissedCallsNotification();//取消未接显示} catch (Exception e) {Log.e("error",e.getMessage());}}}super.onCallStateChanged(state, incomingNumber);}}}
