Android: Non-static method cannot be referenced from static context. Confused? [duplicate]

Question

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);
}

The line giving the error:

EditText.setText(result);

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

Answer 1

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

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

Change your lines

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

to

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

Answer 2

Change

EditText.setText(result);

to

output1.setText(result);
