1、android程序查詢包含"*" "#"的號碼時出錯的解決辦法

代碼錯誤提示: E/AndroidRuntime(1145): Caused by: android.database.sqlite.SQLiteException: near "*": syntax error: , while compiling: SELECT numbertype, new, duration, _id, numberlabel, name, number, type, date FROM calls WHERE (number = **9) ORDER BY date desc  解決:        strQuery = "number = " + strQueryNumber;           callLogCursor = TApplication.nowTApplication.getContentResolver()                  .query(CallLog.Calls.CONTENT_URI, null, strQuery, null,                             "date desc");                                                         查詢代碼改成:                                                             strQuery = "number = " + "'strQueryNumber'";           callLogCursor = TApplication.nowTApplication.getContentResolver()                  .query(CallLog.Calls.CONTENT_URI, null, strQuery, null,                             "date desc");                                 總結:因為"*"為數據庫里的關鍵字(未經證實),所有查找是會報語法錯誤,只需要拼接字符串,把"*"改成非關鍵字即可

2、android通过查询电话号码获取联系人头像

// 取得Intent中的頭像            ivShowImage = (ImageView) findViewById(R.id.call_log_detail_contact_img);          //通话电话号码获取头像uri             Uri uriNumber2Contacts = Uri                   .parse("content://com.android.contacts/"                          + "data/phones/filter/" + strPhoneNumber);          Cursor cursorCantacts = SApplication.nowSApplication                   .getContentResolver().query(uriNumber2Contacts, null, null,                             null, null);            if (cursorCantacts.getCount() > 0) { //若游标不为0则说明有头像,游标指向第一条记录                cursorCantacts.moveToFirst();               Long contactID = cursorCantacts.getLong(cursorCantacts                         .getColumnIndex("contact_id"));               Uri uri = ContentUris.withAppendedId(                      ContactsContract.Contacts.CONTENT_URI, contactID);              InputStream input = ContactsContract.Contacts                      .openContactPhotoInputStream(                               SApplication.nowSApplication                                        .getContentResolver(), uri);                btContactImage = BitmapFactory.decodeStream(input);                Log.i("info", "bt======" + btContactImage);              ivShowImage.setImageBitmap(btContactImage);             } else {//么有头像设置默认头像                ivShowImage                         .setImageResource(R.drawable.call_log_contact_image2);              }
