這是我的代碼我正在掃描使用資興市庫我能夠掃描，但問題是無法在我的actvity類掃描，然後成功的完成它應該當我想獲得價值QR碼打印吐司和掃描活動應完成。請幫助我如何實現這一點。下面獲取掃描的內容使用斑馬線 - Android電子

是我的清單文件：

<activity 
      android:name="com.example.zxing.MainActivity" 
      android:label="@string/app_name" > 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 
       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
     <activity 
      android:name="com.google.zxing.client.android.CaptureActivity" 
      android:configChanges="orientation|keyboardHidden" 
      android:screenOrientation="landscape" 
      android:theme="@android:style/Theme.NoTitleBar.Fullscreen" 
      android:windowSoftInputMode="stateAlwaysHidden" > 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 
       <category android:name="android.intent.category.DEFAULT" /> 
      </intent-filter> 
      <intent-filter> 
       <action android:name="com.google.zxing.client.android.SCAN" /> 
       <category android:name="android.intent.category.DEFAULT" /> 
      </intent-filter> 
     </activity>

有CaptureActivity我剛剛從谷歌斑馬線發現那位此manliest文件librabry請幫助。

上onActivityResult需要調用

IntentResult scanningResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);

使用範例

@Override 
    public void onActivityResult(int requestCode, int resultCode, Intent intent) { 
    IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent); 
    if (result != null) { 
     String contents = result.getContents(); 
     if (contents != null) { 
     Log.d(TAG, "Success"); 
     // result.toString() holds the result info 
     } else { 
     Log.d(TAG, "Failed"); 
     } 
    } 
    }

更新上的掃描按鈕，點擊就以下

Button scanner = (Button) findViewById(R.id.scanner); 
scanner.setOnClickListener(new OnClickListener() { 

    public void onClick(View v) { 
     IntentIntegrator integrator = new IntentIntegrator(MainActivity.this); 
     integrator.addExtra("SCAN_WIDTH", 800); 
     integrator.addExtra("SCAN_HEIGHT", 200); 
     integrator.addExtra("RESULT_DISPLAY_DURATION_MS", 3000L); 
     integrator.addExtra("PROMPT_MESSAGE", "Custom prompt to scan a product"); 
     integrator.initiateScan(IntentIntegrator.PRODUCT_CODE_TYPES); 

    } 

});

對於QR碼掃描做到這一點

IntentIntegrator integrator = new IntentIntegrator(MainActivity.this); 
integrator.initiateScan(IntentIntegrator.QR_CODE_TYPES);

按照test以獲得更多信息。

你可以做一些自定義的功能

private void showMsg(String msg) { 
    // TODO Auto-generated method stub 
    final AlertDialog build = new AlertDialog.Builder(this).create(); 
    build.setTitle("Scanning Result"); 
    build.setMessage(msg); 
    build.setCancelable(true); 
    build.setButton(AlertDialog.BUTTON_POSITIVE, " OK ", 
      new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 
        // TODO Auto-generated method stub 
        build.dismiss(); 
       } 
      }); 
    build.show(); 
}

然後調用函數代替麪包。

showMsg("Product get with " + res);
