I'm on a simple project. I have one activity which contains one fragment (fragment attached using java). The Fragment has 2 Textview which takes integer and string to change dynamically, but while rotating the screen, fragment not working for restoring or continuing the dynamic change. Even my button click stop working. But onSaveInstanceState(Bundle outState) should work properly, where is the bug. My code below:
Activity java code:
package com.blogspot.imti.mygame;
import android.app.FragmentManager;
import android.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.Toast;
public class FragmentHolder extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fragment_holder);
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
GameA gamea = new GameA();
fragmentTransaction.add(R.id.holder_rl1, gamea, "gameATag");
fragmentTransaction.commit();
}
}
Fragment java code:
package com.blogspot.imti.mygame;
import android.os.Bundle;
import android.app.Fragment;
import android.support.v7.app.AppCompatActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;
/**

public class GameA extends Fragment implements View.OnClickListener{
TextView a_tv2;
EditText a_et1;
Button a_b1;
int stepClickCounter;
String [] stepDescriptions = {"Step 1 working",
"Step 2 working",
"Step 3 working",
"Step 4 working",
"Step 5 working",
