Android之——自动挂断电话的实现

通过《Android之——AIDL小结》与《Android之——AIDL深入》两篇博文,相信大家已经对Android AIDL有了一定的了解,下面,我们就利用Android的AIDL实现自动挂断电话的功能,好了,不多说了,我们直接进入主题。

1、准备AIDL文件

挂断电话的AIDL文件都是Android自带的文件,我们可以从Android的源代码中找到这两个文件,它们分别是NeighboringCellInfo.aidl和ITelephony.aidl

我把NeighboringCellInfo.aidl放在项目的android.telephony包下,将ITelephony.aidl放在com.android.internal.telephony包下

NeighboringCellInfo.aid具体内容如下:

Mostly this is used by the * TelephonyManager class. A few places are still using this directly. * Please clean them up if possible and use TelephonyManager insteadl. * * {@hide} */ interface ITelephony { /** * Dial a number. This doesn't place the call. It displays * the Dialer screen. * @param number the number to be dialed. If null, this * would display the Dialer screen with no number pre-filled. */ void dial(String number); /** * Place a call to the specified number. * @param number the number to be called. */ void call(String number); /** * If there is currently a call in progress, show the call screen. * The DTMF dialpad may or may not be visible initially, depending on * whether it was up when the user last exited the InCallScreen. * * @return true if the call screen was shown. */ boolean showCallScreen(); /** * Variation of showCallScreen() that also specifies whether the * DTMF dialpad should be initially visible when the InCallScreen * comes up. * * @param showDialpad if true, make the dialpad visible initially, * otherwise hide the dialpad initially. * @return true if the call screen was shown. * * @see showCallScreen */ boolean showCallScreenWithDialpad(boolean showDialpad); /** * End call or go to the Home screen * * @return whether it hung up */ boolean endCall(); /** * Answer the currently-ringing call. * * If there's already a current active call, that call will be * automatically put on hold. If both lines are currently in use, the * current active call will be ended. * * TODO: provide a flag to let the caller specify what policy to use * if both lines are in use. (The current behavior is hardwired to * answer incoming, end ongoing, which is how the CALL button * is specced to behave.) * * TODO: this should be a oneway call (especially since it's called * directly from the key queue thread). */ void answerRingingCall(); /** * Silence the ringer if an incoming call is currently ringing. * (If vibrating, stop the vibrator also.) * * It's safe to call this if the ringer has already been silenced, or * even if there's no incoming call. (If so, this method will do nothing.) * * TODO: this should be a oneway call too (see above). * (Actually *all* the methods here that return void can * probably be oneway.) */ void silenceRinger(); /** * Check if we are in either an active or holding call * @return true if the phone state is OFFHOOK. */ boolean isOffhook(); /** * Check if an incoming phone call is ringing or call waiting. * @return true if the phone state is RINGING. */ boolean isRinging(); /** * Check if the phone is idle. * @return true if the phone state is IDLE. */ boolean isIdle(); /** * Check to see if the radio is on or not. * @return returns true if the radio is on. */ boolean isRadioOn(); /** * Check if the SIM pin lock is enabled. * @return true if the SIM pin lock is enabled. */ boolean isSimPinEnabled(); /** * Cancels the missed calls notification. */ void cancelMissedCallsNotification(); /** * Supply a pin to unlock the SIM. Blocks until a result is determined. * @param pin The pin to check. * @return whether the operation was a success. */ boolean supplyPin(String pin); /** * Handles PIN MMI commands (PIN/PIN2/PUK/PUK2), which are initiated * without SEND (so dial is not appropriate). * * @param dialString the MMI command to be executed. * @return true if MMI command is executed. */ boolean handlePinMmi(String dialString); /** * Toggles the radio on or off. */ void toggleRadioOnOff(); /** * Set the radio to on or off */ boolean setRadio(boolean turnOn); /** * Request to update location information in service state */ void updateServiceLocation(); /** * Enable location update notifications. */ void enableLocationUpdates(); /** * Disable location update notifications. */ void disableLocationUpdates(); /** * Enable a specific APN type. */ int enableApnType(String type); /** * Disable a specific APN type. */ int disableApnType(String type); /** * Allow mobile data connections. */ boolean enableDataConnectivity(); /** * Disallow mobile data connections. */ boolean disableDataConnectivity(); /** * Report whether data connectivity is possible. */ boolean isDataConnectivityPossible(); Bundle getCellLocation(); /** * Returns the neighboring cell information of the device. */ List getNeighboringCellInfo(); int getCallState(); int getDataActivity(); int getDataState(); /** * Returns the current active phone type as integer. * Returns TelephonyManager.PHONE_TYPE_CDMA if RILConstants.CDMA_PHONE * and TelephonyManager.PHONE_TYPE_GSM if RILConstants.GSM_PHONE */ int getActivePhoneType(); /** * Returns the CDMA ERI icon index to display */ int getCdmaEriIconIndex(); /** * Returns the CDMA ERI icon mode, * 0 - ON * 1 - FLASHING */ int getCdmaEriIconMode(); /** * Returns the CDMA ERI text, */ String getCdmaEriText(); /** * Returns true if CDMA provisioning needs to run. */ boolean getCdmaNeedsProvisioning(); /** * Returns the unread count of voicemails */ int getVoiceMessageCount(); /** * Returns the network type */ int getNetworkType(); /** * Return true if an ICC card is present */ boolean hasIccCard(); } 准备好文件后,会在项目的gen目录下自动生成与两个文件所在包一样的包,同时会自动生成ITelephony.java文件

如下图:

2、新建PhoneUtils类,并写一个方法endCall()
