在片段中显示TextView

Question

I'm trying to display text in Fragment41 automatically right after all rb are checked. How to make this text displayed in Fragment41 ? I tried several ways but I get confused about this implementation. And I know that method getIntent(). here is wrong but I don't know what to change it for). Please help with all this.

My Fragment41

    package make.appaplication;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

public class Fragment41 extends Fragment {


    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_41, container, false);

        TextView textViewDisplayResult = (TextView) getView().findViewById(R.id.text_view_display_result);

        textViewDisplayResult.setText(getIntent().getBooleanExtra("KEY_ANSWER", false)?R.string.Good_answer:R.string.Wrong_answer);
    }
}

Here is Fragment41 in FragmentList in MainActivity

fragmentList.add(new Fragment41());

And here is the code for checkButton

buttonCheckAnswer.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (checkAnswers())
                intent.putExtra("Key Answer", true);

            else
                intent.putExtra("Key Answer", false);
            startActivity(intent);
        }
    });

Just one more issue

I have two strings "Good answers" and "Wrong answers" and the code for them is

buttonCheckAnswer.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (checkAnswers())
                intent.putExtra("Key Answer", true);

            else
                intent.putExtra("Key Answer", false);
            startActivity(intent);
        }
    });

How to add to the above and below code, one more statement string "You haven't checked all answers"?

 textViewDisplayResult.setText(getActivity().getIntent().getBooleanExtra("Key Answer", false)?R.string.Good_answer:R.string.Wrong_answer);

Answer 1

Use same KEY "Key Answer" for both put and get extra data from Intent .

Update Fragment41 as below

package make.appaplication;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

public class Fragment41 extends Fragment {

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view =  inflater.inflate(R.layout.fragment_41, container, false);

        TextView textViewDisplayResult = (TextView) view.findViewById(R.id.text_view_display_result);

        boolean isAnswered = getIntent().getBooleanExtra("is_answered");
        if (isAnswered)
            textViewDisplayResult.setText(getIntent().getBooleanExtra("Key Answer", false)?R.string.Good_answer:R.string.Wrong_answer);
        else
            textViewDisplayResult.setText("You haven't checked all answers");

        return view;
    }

UPDATE:

Use a boolean variable isAnswered to check weather user answered or not. Pass this value to fragment using KEY is_answered .

buttonCheckAnswer.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            if (isAnswered)
                intent.putExtra("is_answered", true);
            else
            {
                if (checkAnswers())
                   intent.putExtra("Key Answer", true);
                else
                   intent.putExtra("Key Answer", false);

                intent.putExtra("is_answered", false);
                startActivity(intent);
            }
        }
    });

Answer 2

You need to use getActivity().getIntent().get... instead of just calling getIntent() . So the whole code in your fragment is:

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View view =  inflater.inflate(R.layout.fragment_41, container, false);

    TextView textViewDisplayResult = (TextView) view.findViewById(R.id.text_view_display_result);
    textViewDisplayResult.setText(getActivity().getIntent().getBooleanExtra("Key Answer", false)?R.string.Good_answer:R.string.Wrong_answer);

    return view;
}

I think I already answered in your previous post.

And, of course I think you did it (if you didn't please read first the documentation https://developer.android.com/guide/components/fragments.html#Adding ), you need to add your fragment to Activity:

getFragmentManager().beginTransaction().add(R.id.fragmentHolder, fragment_41_instance).addToBackStack(null).commit(); 

Another issues

buttonCheckAnswer.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if (!allAnswersChecked())
            intent.putExtra("Key Answer", 1);
        else if (checkAnswers()) 
            intent.putExtra("Key Answer", 2);
        else
            intent.putExtra("Key Answer", 3);
        startActivity(intent);
    }
});

And then:

int result = getActivity().getIntent().getIntExtra("Key Answer", 1);
textViewDisplayResult.setText(result == 1 ? R.string.text_not_checked : 
    result == 2 ? R.string.Good_answer : R.string.Wrong_answer);
