このSQLステートメントを機能させるのに問題があります。誰かが親切で私を助けてくれませんか?
public Cursor getContactMatches(String query, String[] columns)
{
String selection = COL_NAME + " LIKE " + "'%" + "%'"; <---- right here
Log.d("selection", selection);
String[] selectionArgs = new String[] {query+"*"};
return query(selection, selectionArgs, columns);
}
