在android studio中有没有扫描qrcode文件的方法？

implementation 'com.google.zxing:core:3.3.3'
implementation 'com.journeyapps:zxing-android-embedded:3.6.0'

import android.content.Intent;
import android.os.Bundle;
import android.widget.Toast;
import androidx.appcompat.app.AppCompatActivity;
import com.google.zxing.integration.android.IntentIntegrator;
import com.google.zxing.integration.android.IntentResult;

public class MainActivity extends AppCompatActivity {

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

        // 调用扫描方法
        scanQRCodeFile();
    }

    private void scanQRCodeFile() {
        // 创建IntentIntegrator对象
        IntentIntegrator integrator = new IntentIntegrator(this);

        // 设置自定义的扫描活动（可选）
        integrator.setCaptureActivity(CustomScannerActivity.class);

        // 设置提示信息
        integrator.setPrompt("将二维码对准摄像头进行扫描");

        // 开始扫描
        integrator.initiateScan();
    }

    // 接收扫描结果
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        // 获取扫描结果
        IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
        if (result != null && result.getContents() != null) {
            // 获取扫描的内容
            String scannedText = result.getContents();
            Toast.makeText(this, "扫描结果：" + scannedText, Toast.LENGTH_SHORT).show();
        } else {
            Toast.makeText(this, "扫描取消", Toast.LENGTH_SHORT).show();
        }
    }
}
