我有一个 sqlite 语句，但它在 where 子句中给了我错误，并且 where 子句中的函数“sres.getsrthreadid”最后返回给我带有某个数字的 mac 地址。我的功能是：

SResponses sres=new SResponses();
String queryz = "SELECT " + MySQLiteHelper.COLUMN_ID + "," + MySQLiteHelper.COLUMN_MESSAGE+","+MySQLiteHelper.COLUMN_THREADID+","+MySQLiteHelper.COLUMN_POSITION + " FROM " + MySQLiteHelper.TABLE_NAME + " WHERE "+MySQLiteHelper.COLUMN_THREADID+ "="+sres.getsrthreadid();

Log.e("datasource", sres.getsrthreadid());
cursors = database.rawQuery(queryz, null);

Logcat 是：

引用您的输入值，以便 SQLite 可以正确获取它：

String queryz = "SELECT " + MySQLiteHelper.COLUMN_ID + "," + MySQLiteHelper.COLUMN_MESSAGE+","+MySQLiteHelper.COLUMN_THREADID+","
+MySQLiteHelper.COLUMN_POSITION + " FROM " + MySQLiteHelper.TABLE_NAME + " WHERE "
+MySQLiteHelper.COLUMN_THREADID+ "='"+sres.getsrthreadid() + "'; // Here

只需用此替换您的代码

SResponses sres=new SResponses();
String queryz = "SELECT " + MySQLiteHelper.COLUMN_ID + "," + MySQLiteHelper.COLUMN_MESSAGE+","+MySQLiteHelper.COLUMN_THREADID+","+MySQLiteHelper.COLUMN_POSITION + " FROM " + MySQLiteHelper.TABLE_NAME + " WHERE "+MySQLiteHelper.COLUMN_THREADID+ "='" + sres.getsrthreadid() + "'";

Log.e("datasource", sres.getsrthreadid());
cursors = database.rawQuery(queryz, null);
