无法在文本视图中显示翻译后的文本

Question

我正在使用ML工具包的设备上翻译API来翻译文本。虽然翻译工作非常好，但我无法在文本视图中显示翻译后的文本。我尝试使用setText方法，但文本视图中没有显示任何内容。所有内容都显示在logcat中。

我在安卓工作室工作

编辑：这显示了正在下载的模型

TranslatorOptions options =
new TranslatorOptions.Builder()
.setSourceLanguage(TranslateLanguage.ENGLISH)
.setTargetLanguage(TranslateLanguage.BENGALI)
.build();
final Translator englishBengaliTranslator =
Translation.getClient(options);
//DOWNLOAD THE MODEL
DownloadConditions conditions = new DownloadConditions.Builder()
.requireWifi()
.build();
englishBengaliTranslator.downloadModelIfNeeded(conditions)
.addOnSuccessListener(
new OnSuccessListener() {
@Override
public void onSuccess(Object o) {
}
//@Override
public void onSuccess(Void v) {
// Model downloaded successfully. Okay to start translating.
// (Set a flag, unhide the translation UI, etc.)
Toast.makeText(getApplicationContext(), "Model Downloaded.Translation will start ", Toast.LENGTH_SHORT).show();
}
})
.addOnFailureListener(
new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
// Model couldn’t be downloaded or other internal error.
// ...
Toast.makeText(getApplicationContext(), "Model could not be Downloaded. ", Toast.LENGTH_SHORT).show();
}
});

在这段代码中，我调用了translate函数(因为现在已经下载了模型(

englishBengaliTranslator.translate(stringResult)
.addOnSuccessListener(
new OnSuccessListener() {
@Override
public void onSuccess(Object o) {
}
//@Override
public void onSuccess(@NonNull String translatedText1) {
textViewTranslatedText.setText(translatedText1);
}
})
.addOnFailureListener(
new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
// Error.
// ...
Toast.makeText(getApplicationContext(), "Text could not be translated. ", Toast.LENGTH_LONG).show();
}
});

我使用了setText函数，但翻译后的文本仍然显示在logcat中，而不是显示在textview中(翻译效果很好(。我如何在textview中而不是logcat中显示它？任何线索都会有帮助！

这是显示翻译文本的logcat的图像：在此处输入图像描述

试试这个代码，

englishBengaliTranslator.downloadModelIfNeeded(conditions)
.addOnSuccessListener(new OnSuccessListener<Void>() {
@Override
public void onSuccess(Void aVoid) {
// Model downloaded successfully. Okay to start translating.
// (Set a flag, unhide the translation UI, etc.)
Toast.makeText(getApplicationContext(), "Model Downloaded.Translation will start ", Toast.LENGTH_SHORT).show();
}
})
.addOnFailureListener(
new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
// Model couldn’t be downloaded or other internal error.
// ...
Toast.makeText(getApplicationContext(), "Model could not be Downloaded. ", Toast.LENGTH_SHORT).show();
}
});

上面的代码没有任何作用。我刚刚删除了不必要的接口。

但是下面的代码起了一些作用。我的意思是它指定了返回类型。

englishBengaliTranslator.translate(stringResult)
.addOnSuccessListener(new OnSuccessListener<String>() {
@Override
public void onSuccess(String s) {
if(textViewTranslatedText!=null)
textViewTranslatedText.setText(translatedText1);
else
Log.d(TAG, "onSuccess: translation Done but text view null");
}
})
.addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
//Handle onFailure
}
});
