如何在Android中扫描QRCode
我找到了有关如何扫描条形码的教程。但是在我的应用程序中,我必须扫描QR码。如何在Android中扫描QR码?
回答:
try { Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "QR_CODE_MODE"); // "PRODUCT_MODE for bar codes
startActivityForResult(intent, 0);
} catch (Exception e) {
Uri marketUri = Uri.parse("market://details?id=com.google.zxing.client.android");
Intent marketIntent = new Intent(Intent.ACTION_VIEW,marketUri);
startActivity(marketIntent);
}
和在 onActivityResult():
@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0) {
if (resultCode == RESULT_OK) {
String contents = data.getStringExtra("SCAN_RESULT");
}
if(resultCode == RESULT_CANCELLED){
//handle cancel
}
}
}
