1这是完整的源代码。我试过但无法在logcat中显示json响应。如何获得ibm watson的完整回复以及如何在聊天机器人中显示它。
public class MainActivity extends AppCompatActivity {
TextView conversation;
EditText userInput;
Button btnSend;
JSONObject jsonObject;
Object object;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
conversation = (TextView)findViewById(R.id.conversation);
userInput = (EditText)findViewById(R.id.user_input);
btnSend=(Button) findViewById(R.id.sendbutton);
final ConversationService myConversationService =
new ConversationService(
"2017-05-26",
getString(R.string.username),
getString(R.string.password)
);
btnSend.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast.makeText(MainActivity.this, "working", Toast.LENGTH_SHORT).show();
final String inputText = userInput.getText().toString();
conversation.append(
Html.fromHtml("<p><b>You:</b> " + inputText + "</p>")
);
userInput.setText("");
MessageRequest request = new MessageRequest.Builder()
.inputText(inputText)
.build();
myConversationService
.message(getString(R.string.workspace), request)
.enqueue(new ServiceCallback<MessageResponse>() {
@Override
public void onResponse(MessageResponse response) {
final String outputText = response.getText().get(0);
runOnUiThread(new Runnable() {
@Override
public void run() {
conversation.append(
Html.fromHtml("<p><b>Bot:</b> " +outputText + "</p>")
);
}
});
}
@Override
public void onFailure(Exception e) {}
});
}
});}}

在IBM Watson中试用虚拟设备,它运行良好。
但是在我的Android应用中,它没有显示。我认为我的Android代码有问题,请帮忙。 [已编辑的代码图像]

基于Watson Assistant API的示例响应
{
"intents": [
{
"intent": "hello",
"confidence": 0.9755029201507568
}
],
"entities": [],
"input": {
"text": "Hello"
},
"output": {
"generic": [
{
"response_type": "text",
"text": "Hello! What can I do for you?"
}
],
"text": [
"Hello! What can I do for you?"
],

"greeting": {
"0": [
0,
0

}
},
"branch_exited": true,
"branch_exited_reason": "completed"
}
}
}
我认为问题在于这行Android代码
response.getText().get(0);
一旦收到响应,您将尝试读取getText.get(0)下的第一个元素。由于它可以是数组或数组的对象,因此应循环遍历以读取每个值。
替换
final String outputText = response.getText().get(0);
使用
String outputText = "";
int length=response.getText().size();
Log.i(TAG, "run: "+length);
if(length>1) {
for (int i = 0; i < length; i++) {
outputText += '\n' + response.getText().get(i).trim();
}
}
else
outputText = response.getText().get(0);
