How to pass String value from one void method to another void method

Question

I have two void method in the same class. Method2 get data from textview and it stored in a string. I want to get Method2 string in Method1 string. Note: It is an android project. Code is here:

class MainActivity extends AppCompatActivity {
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
}

void Method2()
{
    //this place i want to get str1 value like this:
    // String str2=str1
}
void Method1(View view)
{
    String str1=textView.getText().toString();
}
}

Answer 1

try this code

   public class MainActivity extends AppCompatActivity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

public static String s1 ;
public static String s2 ;


    void Method1(View view) {
      s1 = textView.getText().toString();
    }
 void Method2() {
       s2 = s1 ;
    }
}

Learn and follow Java coding standards. This simple class fails the test.

Method 1 should not return void; it should return the String from the View.

Method 2 should not have an empty parameter list; it should have a String parameter that lets you pass in the value you want.

public class MainActivity extends AppCompatActivity {

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void method2(String s) {
        //this place i want to get str1 value like this:
        // String str2=str1
    }

    public String method1(View view) {
         return textView.getText().toString();
    }
}

You don't have an example of how method1 will get a reference to a View .

This implementation will allow you to get the String out of the View and pass it to method2 . Is that what you want?

Answer 3

A simple way is to add a parameter to method2()

void method2(String str1) {
    //this place i want to get str1 value like this:
    // String str2=str1
}

And call it from method1 .

Assuming you want both methods to be of void return type, you will need to use a class variable. In your code, str1 is local to Method1 , and cannot be accessed from outside Method1 . Using a class variable:

class MainActivity extends AppCompatActivity {
    String str1; 

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    void Method2() {
        String str2 = str1;
    }

    void Method1(View view) {
        str1 = textView.getText().toString();
    }
}

Alternatively, if Method2 should be executed after Method1 :

class MainActivity extends AppCompatActivity {
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    void Method2(String str) {
        String str2 = str1;
    }

    void Method1(View view) {
        String str1 = textView.getText().toString();
        Method2(str1); //pass the string to Method1
    }
}
