我有这个活动，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，但我不知道在哪里放置 counter++；在我的代码中，我到处尝试。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.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Window;
import android.view.WindowManager;
import android.widget.Button;
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{
                mHandler.postDelayed(mLaunchTaskFinish, 2200);
                mHandler.postDelayed(mLaunchTask,2000);
                Intent i = new Intent("rs.androidaplikacijekvizopstekulture.POGRESANODGOVOR");
                startActivity(i);
                }
            }
     };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        requestWindowFeature(Window.FEATURE_NO_TITLE);   //full screen
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

        setContentView(R.layout.kviz);

        Typeface dugmad = Typeface.createFromAsset(getAssets(), "Bebas.ttf");

        bIzlazIzKviza.setTypeface(dugmad);
        rezultat.setTypeface(dugmad);
        question.setTypeface(pitanje);

        TestAdapter mDbHelper = new TestAdapter(this);

“每个用户回答它都会重新加载另一个问题”是什么意思。? 您是否对差异问题使用不同的活动？
您可以对所有问题使用相同的活动，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");
}

从这里很难测试，但看起来像是counter++在行前添加

Answer ans = (Answer) v.getTag();

应该可以正常工作，因为counter只要单击似乎负责回答问题的按钮，它就会增加。请记住，您还需要致电

rezultat.setText(counter+"/10");

再次，更新文本以反映counter.

稍微扩展我的问题。我确实设法用计数器类计算问题，它达到 2/10，但因为我在每个问题后重新加载我的活动，我的 textView 也重新加载到 1/10。我认为这是我的问题的主要原因。
