java - 如何统计提问次数？

Question

我的这个 Activity 有问题和 4 个可能的答案，在每个用户回答后，它会重新加载另一个问题。我在右下角放置了一个 textView，起始值为 1/10 (rezultat.setText(counter+"/10");)。我想在每个问题之后将该值增加到 2/10、3/10 等等，但我不知道将 counter++ 放在哪里；在我的代码中，我到处都试过了。这是我的代码:

import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.graphics.Typeface;

import android.widget.TextView;

public class Kviz extends Activity implements View.OnClickListener{

    Runnable mLaunchTask = new Runnable() {
        public void run() {
            startActivity(getIntent());
        }
     };
     Runnable mLaunchTaskFinish = new Runnable() {
         public void run() {
            finish();
         }
      };

    Button bIzlazIzKviza, bOdgovor1, bOdgovor2, bOdgovor3, bOdgovor4;
    TextView question, proba, rezultat;
    int counter = 1;

    private class Answer {
        public Answer(String opt, boolean correct) {
            option = opt;
            isCorrect = correct;
        }

        String option;
        boolean isCorrect;
    }
    Handler mHandler = new Handler();

    final OnClickListener clickListener = new OnClickListener() {
        public void onClick(View v) {

            Answer ans = (Answer) v.getTag();
            if (ans.isCorrect) {
                mHandler.postDelayed(mLaunchTaskFinish, 1200);
                mHandler.postDelayed(mLaunchTask,1000);
                Intent i = new Intent("rs.androidaplikacijekvizopstekulture.TACANODGOVOR");
                startActivity(i);

            }else{

Answer 1

“每个用户回答它都会重新加载另一个问题”是什么意思。 ？您是否使用不同的 Activity 来解决差异问题？
您可以对所有问题使用相同的 Activity ，当用户按下任何答案按钮时，只需调用一个方法

public void nextQuestion() {
    counter++;
    question.setText("");
    bOdgovor1.setText("");
    bOdgovor2.setText("");
    bOdgovor3.setText("");
    bOdgovor4.setText("");
    //reset your next question and all four options here
    rezultat.setText(counter + "/10");
}
