使用 MainActivity 中 TextEdit 响应中 integer 变量的特定值，以在不同的 class 中使用？

Question

I'm attempting to code an app that takes the users numerical specifications from the main activity in the form of a TextEdit input, convert that to an integer and then use that specific value of the integer and use that value in a separate class file which I will use the result of the class in the main activity.

Is this possible? Here's what I've attempted in the global variables of the main activity:

deadzoneValue = findViewById(R.id.TextView_deadzoneInfo);
public EditText threshold, deadzone;

public String deadzoneString = deadzone.getText().toString(); //deadzone being the name of the 
public int timeLimit = Integer.parseInt(deadzoneString);

public String thresholdString = threshold.getText().toString();
public static int thresholdLimit = Integer.parseInt(thresholdString); 

I'm not sure how to use these in the Deadzone class, which I'm trying to take the specific value and use there.

EDIT : Deadzone.java isn't an activity but a class with functions that are called in the MainActivity .

Answer 1

Using of ClassicSingleton:

public class ClassicSingleton2 {
private static String instance = null;

protected ClassicSingleton2() {

}

public static String getInstance() {
    return instance;
}

public static void setInstance(String instance) {
    ClassicSingleton2.instance = instance;
}

}

You could change type of instance variable to int... And in target code you could get this data:

xRef = ClassicSingleton2.getInstance();

This is very simple.

2: And using of put (putExtra)

Intent oI = new Intent((FirstActivity)this,SecondActivity.class);
            oI.putExtra("XRefCaller",123);

And in target code(activity):

Bundle oBundle = getIntent().getExtras();
    if(oBundle != null){
        oXRefCaller = oBundle.getString("XRefCaller",-1);
        //checking with -1 if the parameter does not exist or is null 
    }
