用逗号分隔所有具有非空值的 EditText

Question

我是 java 和 sql 的初学者，我想整理一些我的 table 的信息。我已将数据库连接到我的 java 项目。我想在我的 table 的一列中获取 EditText 的所有值。我想获取所有非空值并用逗号“,”分隔它们。问题是它会获取 EditText 的所有值，即使它们是空的。

我正在 table 中寻找这种结果：

Answer 1

您可以将所有 EditText 添加到一个数组中

EditText[] editTexts ={nb1,nb2,nb3...};
String content;

并循环数组检查项目内容是否为空将其添加到内容

for(EditText myEditText : editTexts){
    if(!myEditText.getText().toString().isEmpty()){
        content += myEditText.getText().toString() + ","
    }
}

用逗号分隔所有具有非空值的 EditText

Separate all EditText with non Empty value by a comma

java

android-edittext
