Question

Bassicly my aim is too extend a activity so when the user presses Next how many times he wants to , i want to be able to display the value in the Activity2.
I want to somehow still keep the values stored into the variables even when i go into a new activity – im not too sure if thats possible. Any help would be appreciated

1st class

public class Activity extends Activity1 implements OnClickListener {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

}
public void onClick(View v) {
    // TODO Auto-generated method stub
     switch(v.getId()){
        case R.id.Next:

            if (value==0) {
              value=1;
            } 
              else if(value==1){
                  value=2
                 break;
}
               case R.id.one:
                Intent i1 = new Intent(this, Form.class);
            startActivity(i1);
}
}
}

2nd Class

public class Activityv2 extends Activity1 implements OnClickListener {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

}
public void onClick(View v) {
    // TODO Auto-generated method stub
     switch(v.getId()){
        case R.id.button:
            if(value==1){
display.setText("1");


}
else if(value==2)
{
display.setText("2");
}
    }
 }
}

Answer 1

you can store the value in a public static field.

Edit: or you can save it in SharedPreferences, or pass this value through the activity using the bundle

For instance you can save it in this way:

  private void savePreferences(String key, String value){
    SharedPreferences sharedPreferences = getSharedPreferences(PREFS_NAME, 0);
    SharedPreferences.Editor editor = sharedPreferences.edit();
    editor.putString(key, value);
    editor.commit();
   }

  private String loadPreferences(String key, String value){
     SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
     return settings.getString("silentMode", "");
  }
