Zxing扫描qr码时，它将恢复到菜单

Question

我将zxing库导入到我的项目中，扫描仪的工作原理类似于魅力，但是当我扫描qr码时，它说找到了qr码并返回到我设置的菜单有没有什么办法显示结果并将其设置为打开url

package com.Qrgolf.App; 

import java.util.regex.Pattern; 

import com.google.zxing.Result; 

import android.app.Activity; 
import android.content.Intent; 
import android.net.Uri; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.Button; 

public class MainActivity extends Activity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

    Button scan = (Button) findViewById(R.id.SCANBUTTON); 

    scan.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 
      // TODO Auto-generated method stub 
      Intent intent = new Intent("com.google.zxing.client.android.SCAN"); 
      intent.putExtra("SCAN_MODE", "QR_CODE_MODE"); 
      startActivityForResult(intent, 0); 
     } 
    }); 
    }; 

    public void onActivityResult(int requestCode, int resultCode, Intent intent) { 
     if (requestCode == 0) { 
      if (resultCode == RESULT_OK) { 
       String contents = intent.getStringExtra("SCAN_RESULT"); 
       String format = intent.getStringExtra("SCAN_RESULT_FORMAT"); 
       // Handle successful scan 
      } else if (resultCode == RESULT_CANCELED) { 
       // Handle cancel 
      } 
     } 
    } 
}

你应该考虑回到你的旧问题，并接受答案，如果他们是正确的。

此外，您还需要更改onActivityResult（）方法，以执行您想要对QR生成的字符串所做的任何操作。

这里有一个例子：

public void onActivityResult(int requestCode, int resultCode, Intent intent) { 
    if (requestCode == 0) { 
     if (resultCode == RESULT_OK) { 
      String contents = intent.getStringExtra("SCAN_RESULT"); 
      String format = intent.getStringExtra("SCAN_RESULT_FORMAT"); 
      // Handle successful scan 
      Intent intent = new Intent(); 
      intent.setAction(Intent.ACTION_VIEW); 
      intent.setData(android.net.Uri.parse(contents)); 
      startActivity(intent); 
     } else if (resultCode == RESULT_CANCELED) { 
      // Handle cancel 
     } 
    } 
}
