Getting the value in EditText Android

Question

I am having a problem getting the value in the editText of my program. I set the value in a textView so that I can see if the code gets it. But unfortunately it displays something like this:

android.widget.EditText@410e5a58 -> the number after @ sign changes every run in the emulator

Why this happens? This is my code:

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;

    setContentView(R.layout.annual_computation);

    Bundle extras = getIntent().getExtras();

    if(extras != null)
    {
        civil_status2 = extras.getString("user_status");
    }

    final Button btn_compute = (Button) findViewById(R.id.btn_compute_from_annual);
    final Button btn_back = (Button) findViewById(R.id.btn_back_from_annual_computation);

    btn_back.setOnClickListener(new Button.OnClickListener()
    {
        @Override

Answer 1

use netSalary instead of net_salary

td = String.valueOf(netSalary);

As you are passing the edit text instead of the double variable

Answer 2

You are passing an object of EditText ( net_salary ) in td so td will have the the string representation of your net_salary object.

You have stored your value in netSalary varibale so pass that instead :

td = String.valueOf(netSalary);

And for your information :

android.widget.EditText@410e5a58 is the string representation of your EditText object (ie calling toString method of your Edittext object will return this string) .

And value after @ is the memory address of your object. And every time it changes because every time your object is created at different memory locations.

Answer 3

尝试这个，

tax_due.setText( net_salary.getText().toString());

Answer 4

If the problem is here:

td = String.valueOf(net_salary);

Then it is because you are trying to treat net_salary , a widget with a string value set in it, as if it were just a string. Try:

td = String.valueOf(net_salary.getText().toString());
