安卓——屏蔽陌生来电

我只能说网上代码坑惨我了,下载的案例有的都用不来,后来研究了一下,发现也是比较简单的。唯一有点特殊的就是那个aidl文件那里,第一次接触,问了毕业 的学长知道这回事……
一;
该案例就是两个关键类TelephonyManager(获取系统的TelephonyManager管理器)和PhoneStateListener(监听电话状态的)其中的onCallStateChanged((int state, String incomingNumber))就是当电话状态改变时会回调该方法。
接下来再程序中具体介绍一下吧
在oncreat方法中

        //获取系统的TelephonyManager管理器
        tManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
        //获取PhoneStateListener的实例
        pListener = new PhonecallListener();
        //为电话管理器添加监听事件
        tManager.listen(pListener, PhoneStateListener.LISTEN_CALL_STATE);

创建好这些变量

PhonecallListener为继承PhoneStateListener的内部类

//内部类,继承PhoneStateListener的子类
public class PhonecallListener extends PhoneStateListener {
        @Override
        //重写的方法,当电话状态改变时调用。state为改变后的状态....
        public void onCallStateChanged(int state, String incomingNumber) {
            System.out.println("监听开始");
            switch(state)
            {

            case TelephonyManager.CALL_STATE_IDLE:break;
            case TelephonyManager.CALL_STATE_OFFHOOK:break;
            //当有电话拨入时
            case TelephonyManager.CALL_STATE_RINGING:
                System.out.println("来电");
                if(isBlock(incomingNumber))
                {
                    System.out.println("挂电");
                    try
                    {
                        //反射
                        Method method = Class.forName("android.os.ServiceManager")
                                .getMethod("getService", String.class);
                        // 获取远程TELEPHONY_SERVICE的IBinder对象的代理
                        IBinder binder = (IBinder) method.invoke(null,
                            new Object[] { TELEPHONY_SERVICE });
                        // 将IBinder对象的代理转换为ITelephony对象
                        ITelephony telephony = ITelephony.Stub.asInterface(binder);
                        // 挂断电话
                        telephony.endCall();
                        System.out.println("挂断成功");
                    }catch(Exception e){e.printStackTrace();}
                }
                break;
            }
            super.onCallStateChanged(state, incomingNumber);
        }
    }

类的分布图
这里写图片描述
注意这个两个aidl文件以及所在的包
NeighboringCellInfo文件必须位于android.telephony;包中
其内容为

package android.telephony;

parcelable NeighboringCellInfo;

ITelephony文件必须位于com.android.internal.telephony包中
其内容为

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 <code>dial</code> 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<NeighboringCellInfo> getNeighboringCellInfo();

     int getCallState();
     int getDataActivity();
     int getDataState();
}

在eclipse中添加aidl文件的方法
先在这个包中新建.java然后到工作所在文件文件夹中吧java的后缀改成aidl即可.

还有一个重要的就是传限permission

<!-- 授予该应用控制通话的权限 -->
    <uses-permission android:name="android.permission.CALL_PHONE" />    
    <!-- 授予该应用读取通话状态的权限 -->
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <!-- 授予读联系人ContentProvider的权限 -->
    <uses-permission android:name="android.permission.READ_CONTACTS" />
    <!-- 授予写联系人ContentProvider的权限 -->
    <uses-permission android:name="android.permission.WRITE_CONTACTS" />
