错误：-不幸的是应用程序停止了-android studio，运行时致命异常

Question

Whenever I run my application from Android Studio I get an error message

unfortunately, has stopped.

My code:

package com.example.codequiz;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    TextView header,Quetion,Score_view;
    Button True_btn,false_btn,webbutton,email_btn;
    boolean inter;
    int total =0;
    int index = 0;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        header = findViewById(R.id.header);
        Quetion = findViewById(R.id.Quetion);
        Score_view = findViewById(R.id.Score_view);
        True_btn = findViewById(R.id.True_btn);
        false_btn = findViewById(R.id.false_btn);
        webbutton = findViewById(R.id.webbutton);
        email_btn = findViewById(R.id.email_btn);

        String []qt_no = {"java is a object oriented programming.", "Java is the official language of android", "java is widely used by business", "java is made by Sachin", "java is best alternative of Kotlin" };
        Boolean []check = {true,true,true,false,true};

        Quetion.setText(qt_no[index]);

      True_btn.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
              inter= true;
              index++;
              Quetion.setText(qt_no[index]);

          }
      });

      false_btn.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
              inter = false;
              index++;
              Quetion.setText(qt_no[index]);
          }
      });

      if (inter==check[index]){
          total+=1;
      }

      Score_view.setText("Your Score is " +total);
    }
}

Answer 1

Convert qt_no[index] to string type before passing it as an argument to setText() function. This might be one of the reasons for the error Could not find class 'android.view.WindowInsets' .

You can refer to this documentation here
