我搜索了所有论坛和解决方案，但没有一个技巧。我有一个扫描文本并收到扫描文本并显示的应用程序。这是我获得扫描结果的文件：
@Override
public void extractData(RomaniaIdFrontRecognizer.Result result) {
super.extractData(result);
savePreferences("selected", result.getLastName());
add(R.string.PPLastName, result.getLastName());
add(R.string.PPFirstName, result.getFirstName());
add(R.string.PPIdentityCardNumber, result.getCardNumber());
add(R.string.PPSeries, result.getIdSeries());
add(R.string.PPCNP, result.getCnp());
add(R.string.PPNationality, result.getNonMRZNationality());
add(R.string.PPPlaceOfBirth, result.getPlaceOfBirth());
add(R.string.PPAddress, result.getAddress());
add(R.string.PPIssuingAuthority, result.getIssuedBy());
add(R.string.PPSex, result.getNonMRZSex());
add(R.string.PPValidFrom, result.getValidFrom());
add(R.string.PPValidUntil, result.getValidUntil());
}
private void savePreferences(String key, String value){
SharedPreferences sharedPreferences = mContext.getSharedPreferences("weightSetting", MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putString(key, value);
editor.commit();
}
该部分被执行，因为如果我放吐司，消息显示。这是我要接收带有共享preference的变量的文件：

带有共享首选项的发送接收变量可行，但是现在，我不知道原因，第一次获得空变量，如果我再次尝试，那么我先收到我先扫描的内容。因此，该变量仅在第一次使用值扫描的第二次显示。即使我尝试放置一个简单的文本并发送它，它也只会显示我第二次采取行动。但是我重复一遍，文件将被执行，因为如果我放烤面包，它将显示。我认为首先完成了共享首选项变量的接收，然后执行第一个文件中的代码。我试图将代码放入ongreate，on Resume中，但没有任何技巧。任何帮助将不胜感激。
我的解决方案是在接收索格（Thorugh）共享偏好的过程中延迟1秒钟。请参阅下面：
@Override

super.onResume();
// clear saved state to be sure that data is cleared from cache and from file when
// intent optimisation is used
Timer timer = new Timer();
timer.schedule(new TimerTask() {
@Override
public void run() {
// Your logic here...
// When you need to modify a UI element, do so on the UI thread.
// 'getActivity()' is required as this is being ran from a Fragment.
ResultActivity.this.runOnUiThread(new Runnable() {
@Override
public void run() {
// This code will always run on the UI thread, therefore is safe to modify UI elements.
