[英]Getting the value in EditText Android
我在獲取程序的editText中的值時遇到問題。 我在textView中設置了值,以便可以查看代碼是否得到它。 但不幸的是,它顯示如下內容:
android.widget.EditText@410e5a58-> @符號后的數字會更改模擬器中的每次運行
為什么會這樣? 這是我的代碼:
package com.example.ITax;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

使用netSalary
而不是net_salary
td = String.valueOf(netSalary);
在傳遞編輯文本而不是double變量時
您在td
中傳遞了EditText
( net_salary
)對象,因此td
將具有net_salary
對象的字符串表示形式。
您已將您的價值存儲在netSalary
,請通過傳遞它:
td = String.valueOf(netSalary);
並且供您參考:
android.widget.EditText@410e5a58
是您的EditText
對象的字符串表示形式(即,調用您的Edittext
對象的toString
方法將返回此字符串)。
@
之后的值是對象的內存地址。 每次更改時都是因為每次在不同的內存位置創建對象。
嘗試這個,
tax_due.setText( net_salary.getText().toString());
如果問題在這里:
td = String.valueOf(net_salary);
這是因為您試圖將net_salary
(其中設置了字符串值的小部件) net_salary
一個字符串來對待。 嘗試:
td = String.valueOf(net_salary.getText().toString());
