我有以下代码,这是一个使用ZXing库的条形码扫描应用程序。
txtoperatrice.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
IntentIntegrator integrator = new IntentIntegrator(activity);
integrator.setDesiredBarcodeFormats(IntentIntegrator.ALL_CODE_TYPES);
integrator.setPrompt("Scannez le code à barres SVP");
integrator.setCameraId(0);
integrator.setBeepEnabled(true);
integrator.setBarcodeImageEnabled(false);
integrator.initiateScan();
}
});
}
txtoperatrice
是EditText,应在其中显示条形码结果。结果是通过以下代码获得的:
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if (result!=null){
if(result.getContents()==null){
Toast.makeText(this, "Erreur de Scan", Toast.LENGTH_LONG).show();
}
else{
///////// DISPLAY THE CODE IN THE EDITTEXT txtoperatrice
}
}
else{
super.onActivityResult(requestCode, resultCode, data);
}
}

将txtoperatrice
设置为全局变量,然后通过findViewById
方法上的onCreate
对其进行分配
和onActivityResult使用以下代码将其文本设置为结果
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if (result!=null){
if(result.getContents()==null){
Toast.makeText(this, "Erreur de Scan", Toast.LENGTH_LONG).show();
}
else{
txtoperatrice.setText(result.getContents());
}
}
else{
super.onActivityResult(requestCode, resultCode, data);
}
}

如果EditText txtoperatrice对象在您的类中是全局对象,并在活动的onCreate函数中使用findViewById(R.id.yourEditText)给出XML组件的ID。
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if (result!=null){
if(result.getContents()==null){
Toast.makeText(this, "Erreur de Scan", Toast.LENGTH_LONG).show();
}
else{
//you should have a string to put in this argument
//get your result in a string for example resultStr
String resultStr = result.getContents().tostring();
//the above line is just to clear what to do. it may not work exacly
// and then...
txtoperatrice.setText(resultStr);
}
}
else{
super.onActivityResult(requestCode, resultCode, data);
}
}
