推荐答案
您还可以通过扩展CaptureActivity做的。
You can also do by extending CaptureActivity.
public void onClick(View v) {
Intent intent=new Intent(A.this,ScannerActivity.class);
startActivity(intent);
}
ScannerActivity：
ScannerActivity:
public class ScannerActivity extends CaptureActivity {
/** The barcode format. */
String barcodeFormat;
/**
* Called when the activity is first created.
*
* @param savedInstanceState
* the saved instance state
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.barcode_scan);
}
/*
* (non-Javadoc)
*
* @see
* com.google.zxing.client.android.CaptureActivity#handleDecode(com.google
* .zxing.Result, android.graphics.Bitmap)
*/
@Override
public void handleDecode(Result rawResult, Bitmap barcode) {
String barcodeType = rawResult.getBarcodeFormat().toString();
String productId = rawResult.getText();
Toast.makeText(getApplicationContext(),"Contents"+productId +"Format"+barcodeType ,Toast.LENGTH_LONG).show();
//handle intent by sending product id as your wish...
}
}
酒吧code_scan.xml：（不要忘了包括capture.xml）
barcode_scan.xml:(don't forget to include capture.xml)
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<include layout="@layout/capture"/>
</LinearLayout>
