问题 呼叫结束后从呼叫记录中删除呼叫

无论如何我使用4.2.2我必须修改aftab的代码，因为它不适合我。这可能是一个asych问题，我试图做的是在来电结束后立即更新通话记录。我想在删除条目之前我必须给O / S足够的时间更新表，否则它不存在：

private void deleteNumber(String phoneNumber) {

    try {
        Thread.sleep(4000);
        String strNumberOne[] = { phoneNumber };
        Cursor cursor = context.getContentResolver().query(
                CallLog.Calls.CONTENT_URI, null,
                CallLog.Calls.NUMBER + " = ? ", strNumberOne, "");
        boolean bol = cursor.moveToFirst();
        if (bol) {
            do {
                int idOfRowToDelete = cursor.getInt(cursor
                        .getColumnIndex(CallLog.Calls._ID));
                context.getContentResolver().delete(
                        CallLog.Calls.CONTENT_URI,
                        CallLog.Calls._ID + "= ? ",
                        new String[] { String.valueOf(idOfRowToDelete) });
            } while (cursor.moveToNext());
        }
    } catch (Exception ex) {
        Log.v("deleteNumber",
                "Exception, unable to remove # from call log: "
                        + ex.toString());
    }
}

并调用我在另一个线程上运行的函数（因为即时睡眠）：

  new Thread() {
 public void run() {
deleteNumber(incomingNumber);
    }
}.start();

添加睡眠后，在呼叫结束后立即尝试删除时似乎有效。

更新：在最后一条评论意识到我们可以在android提供者调用日志uri上设置contentobserver：

public class BlockerContentObserver extends ContentObserver{

private Context context;
private String phoneNumber;


public void setPhoneNumber(String phoneNumber) {
    this.phoneNumber = phoneNumber;
}

public BlockerContentObserver(Handler handler,Context context) {
    super(handler);
this.context=context;
}

 @Override
    public boolean deliverSelfNotifications() {
        return true;
    }

@Override
public void onChange(boolean selfChange) {
    // TODO Auto-generated method stub
    super.onChange(selfChange);
    Log.v(Consts.TAG,"has call log changed:"+selfChange);
    deleteNumber(phoneNumber);

}   

private void deleteNumber(String phoneNumber) {


    try {

        String strNumberOne[] = { phoneNumber };
        Cursor cursor = context.getContentResolver().query(
                CallLog.Calls.CONTENT_URI, null,
                CallLog.Calls.NUMBER + " = ? ", strNumberOne, "");
        boolean bol = cursor.moveToFirst();
        if (bol) {
            do {
                int idOfRowToDelete = cursor.getInt(cursor
                        .getColumnIndex(CallLog.Calls._ID));
                context.getContentResolver().delete(
                        CallLog.Calls.CONTENT_URI,
                        CallLog.Calls._ID + "= ? ",
                        new String[] { String.valueOf(idOfRowToDelete) });
            } while (cursor.moveToNext());
        }
    } catch (Exception ex) {
        Log.v(Consts.TAG,
                "Exception, unable to remove # from call log: "
                        + ex.toString());
    }
}

}

现在我们注册以使用以下方法监听呼叫日志数据库中的更改：

mContentObserver = new BlockerContentObserver（new Handler（），context）;

然后我们创建一个方法来注册事件或undeigster：

/*handles the registration of our content observer used for monitoring the call log*/
private void RegisterContentObserver(boolean shouldRegister){
    if(shouldRegister)
    {

        context.getContentResolver().registerContentObserver(
                android.provider.CallLog.Calls.CONTENT_URI,
                true,
                mContentObserver);

    }
else {

    try {  
        context.getContentResolver().unregisterContentObserver(mContentObserver);  
    } catch (IllegalStateException ise) {  
        // Do Nothing.  Observer has already been unregistered.  
    }  

}
    }

我只是尝试这种方法，它在我的HTC 4.0.3上工作得很好

private void deleteNumber() {
            try {
                String strNumberOne[] = { "00577698160" };
                Cursor cursor = getContentResolver().query(CallLog.Calls.CONTENT_URI, null, CallLog.Calls.NUMBER + " = ? ", strNumberOne, "");
                boolean bol = cursor.moveToFirst();
                if (bol) {
                    do {
                        int idOfRowToDelete = cursor.getInt(cursor.getColumnIndex(CallLog.Calls._ID));
                        getContentResolver().delete(Uri.withAppendedPath(CallLog.Calls.CONTENT_URI, String.valueOf(idOfRowToDelete)), "", null);
                    } while (cursor.moveToNext());
                }
            } catch (Exception ex) {
                System.out.print("Exception here ");
            }
        }

早期答案的修改版本。你真的不需要一个while循环。你也不需要 Thread.sleep(4000)，注册一个 ContentObserver 对于 CallLog.Calls.CONTENT_URI 并调用以下方法 onChange。但就在打电话之前，请确保取消注册 ContentObserver

public static void deleteLastCallLog(Context context, String phoneNumber) {

        try {
            //Thread.sleep(4000);
            String strNumberOne[] = { phoneNumber };
            Cursor cursor = context.getContentResolver().query(
                    CallLog.Calls.CONTENT_URI, null,
                    CallLog.Calls.NUMBER + " = ? ", strNumberOne, CallLog.Calls.DATE + " DESC");

            if (cursor.moveToFirst()) {
                    int idOfRowToDelete = cursor.getInt(cursor.getColumnIndex(CallLog.Calls._ID));                      
                    int foo = context.getContentResolver().delete(
                            CallLog.Calls.CONTENT_URI,
                            CallLog.Calls._ID + " = ? ",
                            new String[] { String.valueOf(idOfRowToDelete) });

            }
        } catch (Exception ex) {
            Log.v("deleteNumber",
                    "Exception, unable to remove # from call log: "
                            + ex.toString());
        }
    }
