Question

I have a main activity class and find class. I need to access variable of main activity variable’s that is “name” from find class. I tried to access with below snippet code but I get an error. How can I access main activity variables from another class ?

public class main extends Activity {

     public static String name=null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button button1=(Button)findViewById(R.id.button1);

        final EditText edittext = (EditText) findViewById(R.id.editText1);

        button1.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                name=edittext.getText().toString();

            }
        });                                                
}

My second class….

public class find {

public void finder(){

    main mainactivity=new main();
    String incoming_name =mainactivity.name;//I can not use like that ? 
            // do something 
}

}

Answer 1

1) You shouldn’t instantiate an activity, intents start activities

2) You have declared the variable public static, so you can simply reference it (without instantiating the class) by main.name…
