Question

我有一个ScrollView，它具有大约13个EditText。我正在尝试将语音转换为文本，因此，当用户触摸任何EditText并单击“讲话”按钮并开始讲话时，它将转换为该EditText的文本，而当他再次触摸另一个EditText时，它将转换为该文本。我使用了循环，但在所有13个EditText中都发现了一个语音的结果。我还添加了一个break语句，但效果不佳。

 public void onResults(Bundle bundle) {
                //getting all the matches
                ArrayList<String> matches = bundle
                        .getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);


                if (matches != null) {
                    for (int j = 0; j < speEdtId.length; j++) {
                        eEdit = findViewById(speEdtId[j]);

                        if (speEdtId[j]==speEdtId[0]) {
                            eEdit.setText(matches.get(0));
                        } else if (speEdtId[j]==speEdtId[1]) {
                            eEdit.setText(matches.get(0));
                        } else if (speEdtId[j]==speEdtId[2]) {
                            eEdit.setText(matches.get(0));}

                                      .
                                      .
                                      .
break;
                    }
 }}

Answer 1

您正在为每个Edittext设置相同的值。您可以做的是：

                              if (speEdtId[j]==speEdtId[0]) {
                                eEdit.setText(matches.get(0));
                                matches.clear();
                            }

然后还将标记设置为每个Edittext，并在循环内使用标记查找。希望这会有所帮助

似乎您将有很多Speech EditText，但我不确定您希望程序如何与EditText一起使用，因此在解决方案中将使用TextView。我认为，使用RecyclerViews比手动创建13个EditText更好，更有效。

首先，我将创建一个Speech对象。您可以添加任意数量的变量，例如语音的时间戳记

Speech.java

public class Speech {
    private String speechInText;
    private String speech;

    public Speech(){

    }

    public Speech(String speechInText, String speech) {
        this.speechInText = speechInText;
        this.speech = speech;
    }

    public String getSpeechInText() {
        return speechInText;
    }

    public void setSpeechInText(String speechInText) {
        this.speechInText = speechInText;
    }

    public String getSpeech() {
        return speech;
    }

    public void setSpeech(String speech) {
        this.speech = speech;
    }

}

然后，我将为每个演讲创建一个适配器

SpeechAdapter.java

public class SpeechAdapter extends RecyclerView.Adapter<SpeechAdapter.ViewHolder>  {
    public static final String TAG = SpeechAdapter.class.getName();

    public interface OnItemClickListener {
        void onItemClick(Speech speech, int pos);
    }

    private List<Speech> speeches;
    private AppCompatActivity parentActivity;
    private final OnItemClickListener listener;

    public SpeechAdapter(AppCompatActivity parentActivity, List<Speech> speeches, OnItemClickListener listener) {
        this.parentActivity = parentActivity;
        this.speeches = speeches;
        this.listener = listener;
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        public TextView speechInTextTV;

        public ViewHolder(View v) {
            super(v);
            parentActivity.runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    speechInTextTV = itemView.findViewById(R.id.speechInTextTV);
                }
            });
        }

        public void bind(final Speech speech,final int pos, final OnItemClickListener listener) {
            itemView.setOnClickListener(new View.OnClickListener() {
                @Override public void onClick(View v) {
                    listener.onItemClick(speech, pos);
                }
            });
        }
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.adapter_speech_list, parent, false);

        return new ViewHolder(v);
    }

    @Override
    public void onBindViewHolder(@NonNull final ViewHolder holder, int pos) {
        final Speech speech = speeches.get(pos);
        holder.speechInTextTV.setText(speech.getSpeechInText());

        holder.bind(speech, pos, listener);
    }

    @Override
    public int getItemCount() {
        return speeches.size();
    }
}

接下来，我将为适配器创建一个XML文件

adapter_speech_list.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:background="@color/white">

    <TextView
        android:id="@+id/speechInTextTV"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        android:padding="20dp"/>

</android.support.constraint.ConstraintLayout>

最后，活动文件或片段文件

SpeechActivity.java

public class SpeechActivity extends AppCompatActivity{
    public static final String TAG = SpeechActivity.class.getName();

    private SpeechAdapter speechAdapter;
    private List<Speech> speeches = new ArrayList<>();
    private RecyclerView speechRV;
    private int selectedSpeechPosition;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_speech);

        speechRV = findViewById(R.id.speechRV);

        //I add 13 text views manually here (with empty data)
        for(int i = 0; i < 13; i++){
            speeches.add(new Speech("",""));
        }

        speechAdapter = new SpeechAdapter(this, speeches, new SpeechAdapter.OnItemClickListener() {
            @Override
            public void onItemClick(Speech speech, int position) {
                /*
                    you convert speech to text here
                 */
                selectedSpeechPosition = position;
            }
        });

        speechRV.setNestedScrollingEnabled(false);
        speechRV.setAdapter(speechAdapter);
        speechRV.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false));
    }

    public void onResults(Bundle bundle) {
        //getting all the matches
        ArrayList<String> matches = bundle
                .getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);

        /*here you get the result of the converted speech and update the speeches list and then update the adapter to refresh the view*/
        String convertedSpeech = "<PUT_YOUR_RESULT_HERE>";
        speeches.set(selectedSpeechPosition,new Speech(convertedSpeech,"user's original speech or something else?"));
        speechAdapter.notifyDataSetChanged();
    }
}

最后是活动的xml文件

activity_speech.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:background="@color/white"
    android:clickable="true">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/speechRV"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical"/>
</android.support.constraint.ConstraintLayout>

此解决方案仅是示例，如果我在您的位置，我的解决方法也是如此。您应该学习代码并自己进行操作以满足自己的要求。

基本上，您应该将某种类型的数据传递到语音列表中，并在onResult函数中更新适配器，然后将使用新数据刷新回收站视图。当我在活动文件中初始化适配器时，我已经实现了OnItemClick函数，因此当用户在“回收者”视图中单击某个项目时，它将保存所选语音的位置，以便将其保存在onResult函数中，您可以知道自己是哪种语音应该更新（通过使用selectedSpeechPosition）
