android 来电自动接听和自动挂断
android 来电自动接听和自动挂断
注意:android2.3版本不支持下面的自动接听方法。(会抛异常:java.lang.SecurityException: Neither user xxxxx nor current process has android.permission.MODIFY_PHONE_STATE.)
第一步:准备应用环境需要的系统包和aidl文件。
(1)在应用中创建包:android.telephony
将android系统框架下的\framework\telephony\java\android\telephony目录中的NeighboringCellInfo.aidl文件复制到上面创建的包(android.telephony )中;
(2)在应用中创建包:com.android.internal.telephony
将android系统框架下的\framework\telephony\java\com\android\internal\telephony目录中的ITelephony.aidl文件复制到上面创建的包(com.android.internal.telephony )中;
第二步:创建一个获取ITelephony的方法
PhoneUtils.java
package com.zhouzijing.android.demo; import java.lang.reflect.Method; import com.android.internal.telephony.ITelephony; import android.telephony.TelephonyManager; public class PhoneUtils { /** * 根据传入的TelephonyManager来取得系统的ITelephony实例. * @param telephony * @return 系统的ITelephony实例 * @throws Exception */ public static ITelephony getITelephony(TelephonyManager telephony) throws Exception { Method getITelephonyMethod = telephony.getClass().getDeclaredMethod("getITelephony"); getITelephonyMethod.setAccessible(true);//私有化函数也能使用 return (ITelephony)getITelephonyMethod.invoke(telephony); } }
第三步:创建电话广播拦截器
MyPhoneBroadcastReceiver.java
package com.zhouzijing.android.demo; import com.android.internal.telephony.ITelephony; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.telephony.TelephonyManager; import android.util.Log; public class MyPhoneBroadcastReceiver extends BroadcastReceiver { private final static String TAG = MyPhone.TAG; @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); Log.i(TAG, "[Broadcast]"+action); //呼入电话 if(action.equals(MyPhone.B_PHONE_STATE)){ Log.i(TAG, "[Broadcast]PHONE_STATE"); doReceivePhone(context,intent); } } /** * 处理电话广播. * @param context * @param intent */ public void doReceivePhone(Context context, Intent intent) { String phoneNumber = intent.getStringExtra( TelephonyManager.EXTRA_INCOMING_NUMBER); TelephonyManager telephony = (TelephonyManager)context.getSystemService( Context.TELEPHONY_SERVICE); int state = telephony.getCallState(); switch(state){ case TelephonyManager.CALL_STATE_RINGING: Log.i(TAG, "[Broadcast]等待接电话="+phoneNumber); try { ITelephony iTelephony = PhoneUtils.getITelephony(telephony); iTelephony.answerRingingCall();//自动接通电话 //iTelephony.endCall();//自动挂断电话 } catch (Exception e) { Log.e(TAG, "[Broadcast]Exception="+e.getMessage(), e); } break; case TelephonyManager.CALL_STATE_IDLE: Log.i(TAG, "[Broadcast]电话挂断="+phoneNumber); break; case TelephonyManager.CALL_STATE_OFFHOOK: Log.i(TAG, "[Broadcast]通话中="+phoneNumber); break; } } }
第四部:注册电话广播拦截器
MyPhone.java
package com.zhouzijing.android.demo; import android.app.Activity; import android.content.IntentFilter; import android.os.Bundle; import android.telephony.TelephonyManager; import android.util.Log; import android.view.View; public class MyPhone extends Activity { public final static String TAG = "MyPhone"; public final static String B_PHONE_STATE = TelephonyManager.ACTION_PHONE_STATE_CHANGED; private MyPhoneBroadcastReceiver mBroadcastReceiver; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.my_phone); } //按钮1-注册广播 public void registerThis(View v) { Log.i(TAG, "registerThis"); mBroadcastReceiver = new MyPhoneBroadcastReceiver(); IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction(B_PHONE_STATE); intentFilter.setPriority(Integer.MAX_VALUE); registerReceiver(mBroadcastReceiver, intentFilter); } //按钮2-撤销广播 public void unregisterThis(View v) { Log.i(TAG, "unregisterThis"); unregisterReceiver(mBroadcastReceiver); } }
第5步:在AndroidManifest.xml配置权限
iTelephony.answerRingingCall();//自动接通电话
必须有权限 android.permission.MODIFY_PHONE_STATE
iTelephony.endCall();//自动挂断电话
必须有权限 android.permission.CALL_PHONE
