Android：无法从静态上下文引用非静态方法。困惑？

问题描述

我非常非常喜欢Java和编程。我写了一个基本程序，用来添加用户输入的2个数字并将它们添加起来并在输出框中显示它们，但是我得到非静态方法setText（java.lang.CharSequence）'无法引用来自静态上下文，但我不知道静态的东西是什么

I am extremely extremely new to Java and programming in general. I wrote this for a basic program to add 2 numbers input by the user and add them up and display them in the output box, however I'm getting "Non-static method 'setText(java.lang.CharSequence)' cannot be referenced from a static context", but I don't know what the static thing is

    private void onClick(View v){
    EditText input1 = (EditText) findViewById(R.id.input1);
    double calc1 =  Double.parseDouble(String.valueOf(input1));
    EditText input2 = (EditText) findViewById(R.id.input2);
    double calc2 = Double.parseDouble(String.valueOf(input2));
    double total = calc1 + calc2;
    String result = Double.toString(total);
    EditText output1 = (EditText)findViewById(R.id.output);
    EditText.setText(result);
    }

给出错误的行：

    EditText.setText(result);

很抱歉，如果我非常无能，但我搜索过，我真的不明白如何解决它。谢谢。

Sorry if I'm being extremely incompetent but I searched and I couldn't really understand how to fix it. Thanks.

推荐答案

在静态上下文中，您没有对象（类的实例），而是实例变量和方法依赖于它们。

In a static context, you don't have an object (instance of the class), but the instance variables and methods depend on them.

你有一个名为output1的实例，但你尝试通过类的名称调用你的方法'setText'（这是一种静态方法） 。

You have an instance, called output1, but you try to call your method 'setText' through the class's name (which is a static approach).

更改行

EditText output1 = (EditText)findViewById(R.id.output);
    EditText.setText(result);

到

EditText output1 = (EditText)findViewById(R.id.output);
    output1.setText(result);
