我成功地使用zxing来扫描代码,通过调用安装的条形码读取器的意图,但是当它发出哔声并表示良好的扫描时,我期望zxing活动会返回控制,所以我可以处理结果,但是它坐在那里并尝试再次扫描.我必须按后退按钮,然后返回,我可以做下一步.当我打电话给扫描仪时,有没有一些明显的标志？
任何建议感激不尽.非常感谢.
这是我的代码：
public boolean onTouchEvent(final MotionEvent event) {
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("com.google.zxing.client.android.SCAN.SCAN_MODE","QR_CODE_MODE");
startActivityForResult(intent,0);
return true;
}
public void onActivityResult(int requestCode,int resultCode,Intent intent) {
super.onActivityResult(requestCode,resultCode,intent);
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
String contents = intent.getStringExtra("SCAN_RESULT");
String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
// Handle successful scan
String s = "http://www.google.com/search?q=";
s += contents;
Intent myIntent1 = new Intent(Intent.ACTION_VIEW,Uri.parse(s));
startActivity(myIntent1);
}
else
if (resultCode == RESULT_CANCELED) {
// Handle cancel
}
}
}
}
