zxing条码扫描器需要向android清单文件添加什么？

冯德宇
2023-03-14
问题内容：

我已经使用Intent将zxing条形码扫描仪集成到我的应用程序中，但是我对清单中需要的内容一无所知。截至目前，当我单击按钮以启动相机时，它会导致强制关闭，当我单击强制关闭时，条形码扫描仪将在后面打开并起作用。链接到该按钮的代码如下：

    public void onClick(View v) {
    Intent intent = new Intent("com.google.zxing.client.android.SCAN");
    intent.setPackage("com.google.zxing.client.android");
    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) {
            contents = intent.getStringExtra("SCAN_RESULT");
            format = intent.getStringExtra("SCAN_RESULT_FORMAT");
            // Handle successful scan         
            } else if (resultCode == RESULT_CANCELED) {
                // Handle cancel          
            }
        }
}

这是android清单文件：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="andrew.markley.android.firstGame"

            </intent-filter> 
    </activity>         
    <activity android:name=".Scan" android:screenOrientation="landscape" android:configChanges="orientation|keyboardHidden"                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.LAUNCHER"/>        </intent-filter>        <intent-filter>          <action android:name="com.google.zxing.client.android.SCAN"/>          <category android:name="android.intent.category.DEFAULT"/>        </intent-filter>  </activity>
    </application>

  <uses-permission android:name="android.permission.CAMERA"/>
</manifest>

问题答案：

ZXing项目提供了一些通过其Wiki上的Intent调用XZing的代码：

http://code.google.com/p/zxing/source/browse/trunk/android-
integration/src/com/google/zxing/integration/android/IntentIntegrator.java

如果使用该代码，则无需在清单文件中添加任何内容。从您的活动中，您可以致电

IntentIntegrator.initiateScan(this);

这将确保您已安装ZXing，并提示用户通过Marketplace进行安装。
