本文实例讲述了Android编程中黑名单的实现方法。分享给大家供大家参考，具体如下：
说明：由于挂断电话android api不是对外开放的，所以需要使用反射的方法得到拨打电话的服务。
1.将android源代码中的"aidl"文件拷贝到项目中
这样项目中会生成两个包：android.telephony；此包中文件为：NeighboringCellInfo.aidl
com.android.internal.telephony;此包中文件为：ITelephony.aidl
2.通过反射挂断电话；代码如下：

/*** 挂断电话*/public void endCall() { try { Method method = Class.forName("android.os.ServiceManager").getMethod("getService", String.class); IBinder binder = (IBinder) method.invoke(null, new Object[]{TELEPHONY_SERVICE}); ITelephony telephony = ITelephony.Stub.asInterface(binder); telephony.endCall(); } catch (Exception e) { e.printStackTrace(); }} |
3.删除通话记录中的记录

/*** 删除呼叫记录*/public void deleteCallLog(String incomingNumber) { ContentResolver resolver = getContentResolver(); Cursor cursor = resolver.query(CallLog.Calls.CONTENT_URI, null,"number=?", new String[]{incomingNumber}, null); if(cursor.moveToNext()){ String id = cursor.getString(cursor.getColumnIndex("_id")); resolver.delete(CallLog.Calls.CONTENT_URI, "_id=?", new String[]{id}); }} |
4.直接这样调用是不能删除电话记录的，因为生成电话记录的过程是一个异步的过程，在挂断电话之后不能立即删除电话记录，所以这里要使用ContentObserver（内容观察者）

private class MyObserver extends ContentObserver{ private String incomingNumber; public MyObserver(Handler handler,String incomingNumber) { super(handler); this.incomingNumber = incomingNumber; } @Override public void onChange(boolean selfChange) { super.onChange(selfChange); deleteCallLog(incomingNumber); getContentResolver().unregisterContentObserver(this); }} |
6.最后把整个service代码贴到下面
