如何采取QR扫描结果，并把它变成一个字符串？ [英] How to take the QR scanner result and make it into a string?

问题描述

我如何走'这个'值（6号线），并把它变成一个字符串？

  @覆盖
保护无效的onCreate（捆绑savedInstanceState）{
    super.onCreate（savedInstanceState）;
    的setContentView（R.layout.activity_qrscanner）;
    片段=（酒吧codeFragment）getSupportFragmentManager（）findFragmentById（R.id.sample）。
    fragment.setScanResultHandler（本）;
    BTN =（（按钮）findViewById（R.id.scan））;
    btn.setEnabled（假）;}
 

例如，而不是仅仅敬酒的价值，我可以使用的价值，使之成为一个字符串，然后将其携带到另一个活动。

  @覆盖
公共无效scanResult（ScanResult结果）{
    btn.setEnabled（真）;
    意向意图=新意图（QrscannerActivity.this，ProductInfoActivity.class）;
    startActivity（意向）;
    Toast.makeText（此，result.getRawResult（）的getText（），Toast.LENGTH_LONG）.show（）;}
 

解决方案

您应该使用谷歌ZXing酒吧code扫描仪库，以及低于code：

 延伸活动{
    @覆盖
    公共无效的onCreate（捆绑savedInstanceState）{
        super.onCreate（savedInstanceState）;
        的setContentView（R.layout.main）;
        HandleClick HC =新HandleClick（）;
        findViewById（R.id.butQR）.setOnClickListener（HC）;
        findViewById（R.id.butProd）.setOnClickListener（HC）;
        findViewById（R.id.butOther）.setOnClickListener（HC）;
    }
    私有类HandleClick实现OnClickListener {
        公共无效的onClick（查看为arg0）{
        意向意图=新意图（com.google.zxing.client.android.SCAN）;
        开关（arg0.getId（））{
            案例R.id.butQR：
                intent.putExtra（SCAN_MODE，QR_ code_MODE）;
                打破;
            案例R.id.butProd：
                intent.putExtra（SCAN_MODE，PRODUCT_MODE）;
                打破;
            案例R.id.butOther：
                intent.putExtra（SCAN_FORMATS，code_39，code_93，code_128，DATA_MATRIX，ITF，CODABAR）;
                打破;
        }
        startActivityForResult（意向，0）; //酒吧code扫描仪来扫描我们
        }
    }
    公共无效的onActivityResult（INT申请code，INT结果code，意图意图）{
        如果（要求code == 0）{
            TextView的tvStatus =（的TextView）findViewById（R.id.tvStatus）;
            TextView的tvResult =（的TextView）findViewById（R.id.tvResult）;
            如果（结果code == RESULT_OK）{
                tvStatus.setText（intent.getStringExtra（SCAN_RESULT_FORMAT））;
                tvResult.setText（intent.getStringExtra（SCAN_RESULT））;
            }否则如果（结果code == RESULT_CANCELED）{
                tvStatus.setText（preSS按钮开始扫描。）;
                tvResult.setText（扫描取消。）;
            }
        }
    }
}
 

How do I take the 'this' value ( from the 6th line) and make it into a string?

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_qrscanner);
    fragment = (BarcodeFragment)getSupportFragmentManager().findFragmentById(R.id.sample);
    fragment.setScanResultHandler(this);
    btn = ((Button)findViewById(R.id.scan));
    btn.setEnabled(false);

}

For example instead of just toasting the value, can I use the value and make it into a string and then carrying it into another activity.

@Override
public void scanResult(ScanResult result) {
    btn.setEnabled(true);
    Intent intent = new Intent(QrscannerActivity.this,ProductInfoActivity.class);
    startActivity(intent);
    Toast.makeText(this, result.getRawResult().getText(), Toast.LENGTH_LONG).show();



}

解决方案

You should use the Google ZXing Barcode Scanner library and with the below code:

extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        HandleClick hc = new HandleClick();
        findViewById(R.id.butQR).setOnClickListener(hc);
        findViewById(R.id.butProd).setOnClickListener(hc);
        findViewById(R.id.butOther).setOnClickListener(hc);
    }    
    private class HandleClick implements OnClickListener{
        public void onClick(View arg0) {
        Intent intent = new Intent("com.google.zxing.client.android.SCAN");     
        switch(arg0.getId()){
            case R.id.butQR:
                intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
                break;
            case R.id.butProd:
                intent.putExtra("SCAN_MODE", "PRODUCT_MODE");
                break;
            case R.id.butOther:
                intent.putExtra("SCAN_FORMATS", "CODE_39,CODE_93,CODE_128,DATA_MATRIX,ITF,CODABAR");
                break;
        }
        startActivityForResult(intent, 0);  //Barcode Scanner to scan for us
        }
    }
    public void onActivityResult(int requestCode, int resultCode, Intent intent) {
        if (requestCode == 0) {
            TextView tvStatus=(TextView)findViewById(R.id.tvStatus);
            TextView tvResult=(TextView)findViewById(R.id.tvResult);
            if (resultCode == RESULT_OK) {
                tvStatus.setText(intent.getStringExtra("SCAN_RESULT_FORMAT"));
                tvResult.setText(intent.getStringExtra("SCAN_RESULT"));
            } else if (resultCode == RESULT_CANCELED) {
                tvStatus.setText("Press a button to start a scan.");
                tvResult.setText("Scan cancelled.");
            }
        }
    }
}
