1. 我用扫描仪代码的用意启动z:
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
startActivityForResult(intent,REQUEST_QR_CODE);
但这只是回报内容/格式。 如果一对x条条条码扫描仪表扫描仪,它将确定其内容,如其URL或联系,并促使其采取适当行动,如在浏览器上增加联系或开放。
当使用意图触发同一目的时,如何做到相同
有一个文件解释将由谁获得的价值观。
itent.getStringExtra("SCAN_RESULT");
intent.getStringExtra("SCAN_RESULT_FORMAT");
i 希望了解为QR代码重新编号的不同内容
<代码>Intent机制是指,如果你想要提供某种不同于Barcode Scanner所能提供的行动。 在这种情况下,正如你希望用户开放和使用Barcode Scanner一样,这只是合理的。
You do that a little differently but it is also just a matter of sending the right Intent. Off the top of my head:
Intent intent = new Intent("android.intent.action.MAIN");
intent.addCategory("android.intent.category.LAUNCHER");
intent.setPackage("com.google.zxing.client.android");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
activity.startActivity(intent);
