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

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.

(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.

}

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" />
