Android SQLite:无法在索引1处绑定参数，因为该索引超出范围。该语句有0个参数

在尝试使数据库工作时遇到了几个问题现在我遇到了以下错误

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.stu54259.plan2cook/com.stu54259.plan2cook.Recipe}: java.lang.IllegalArgumentException: Cannot bind argument at index 1 because the index is out of range.  The statement has 0 parameters.

您的查询列名与您试图使用光标检索的列名不同

还要注意，游标区分大小写，因此列应该与物理表中的列完全相同

您还应该向查询中添加所需的where子句，如“%”？%”

这一问题现在已经解决，对toString和layout xml进行了调整，并结合此处提供的帮助解决了此问题。非常感谢，我相信我还会有更多的内容。

配方搜索查询不应该有一个where子句，其中包含要格式化的参数吗？

public void loadRecipe() {
    itemRecipe.clear();
    db = (new DatabaseManager(this).getWritableDatabase());
    String RECIPE_SEARCH = " SELECT A.recipe, A.ingredient_quantity, B.measurement_name, B.ingredient_name, B.description " +
            "FROM " + DatabaseManager.TABLE_QUANTITY + " AS A JOIN " + DatabaseManager.TABLE_INGREDIENTS +
            " AS B ON A.ingredient = B.ingredient_name";
    String selectQuery = "";
    selectQuery = RECIPE_SEARCH + " WHERE A.recipe LIKE ?";
    c = db.rawQuery(selectQuery, new String[]{"%" + search_name + "%"});
    if (c.moveToFirst()) {
        do {
            RecipeList recipeList = new RecipeList();
            recipeList.setId(c.getInt(c.getColumnIndex("COL_ID")));
            recipeList.setIngredient_amount(c.getString(c.getColumnIndex("COL_INGREDIENT_QUANTITY")));
            recipeList.setMeasurement_name(c.getString(c.getColumnIndex("COL_MEASUREMENT_NAME")));
            recipeList.setIngredient_name(c.getString(c.getColumnIndex("COL_INGREDIENT_NAME")));
            recipeList.setDescription(c.getString(c.getColumnIndex("COL_DESCRIPTION")));
            itemRecipe.add(recipeList);
        } while (c.moveToNext());
        c.close();
    }

}
