Java android.content.res.Resources$NotFoundException:字符串资源ID 0x4

我一直在尝试制作一个计时器应用程序。用户将输入秒数，搜索栏以递减方式移动。但只要我点击按钮，进度条就会移动到该值，但应用程序崩溃。我认为在进度条更新之前，代码运行良好，但在更新之后，它崩溃了。我已经为这个代码挣扎了几个小时。请帮忙，我是android应用开发的新手

以下是日志：-

我认为问题在于：

textView.setText(secondsLeft);

尝试：

无法将整数值放入TextView。

单击“在后台线程上运行”，因此请通过runOnUIThread或使用视图处理程序运行

package com.example.timer;

import android.os.CountDownTimer;

import android.view.View;

import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

        final TextView textView = findViewById(R.id.textView2);
        final SeekBar seekBar = findViewById(R.id.seekBar);
        int timeGiven = Integer.parseInt(editText.getText().toString());
        seekBar.setMax(timeGiven);
        seekBar.setProgress(timeGiven);

        new CountDownTimer(timeGiven*1000, 1000){
            public void onTick(long millisecondsLeft){

                int secondsLeft = (int) millisecondsLeft/1000;
                seekBar.setProgress(secondsLeft);
                textView.setText(secondsLeft);

            public void onFinish(){

                Toast.makeText(getApplicationContext(),"BOOM",Toast.LENGTH_SHORT).show();
            }
        }.start();
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

textView.setText(secondsLeft);

textView.setText(String.valueOf(secondsLeft));
