使用自定义数组适配器进行文本转语音 Android

Question

我制作了一个自定义适配器，现在我想在其构造函数中向语音添加一个文本，但我不知道该怎么做。

MainActivity

ArrayList<Word> numbers = new ArrayList<Word>(); //Initializing numbers.add(new Word("one", "uno", R.drawable._nmbericon)); //this is how i want to pass my Pronunciation as the fourth parameter // numbers.add(new Word("one", "onu", R.drawable._nmbericon,"unoo")); WordAdapter adapter = new WordAdapter(this, numbers); ListView listView = (ListView) findViewById(R.id.listview); listView.setAdapter(adapter); //->> TEXT TO SPEECH STARTS HERE listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { textToSpeech = new TextToSpeech(NumbersActivity.this, new TextToSpeech.OnInitListener() { @Override public void onInit(int status) { if (status == TextToSpeech.SUCCESS){ result = textToSpeech.setLanguage(Locale.ENGLISH); String toSpeak = "ONUU"; Toast.makeText(getApplicationContext(), toSpeak, Toast.LENGTH_SHORT).show(); textToSpeech.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null); }else{ Toast.makeText(getApplicationContext(), "Not Supported in your Device", Toast.LENGTH_SHORT).show(); } } }); } }); //->> TEXT TO SPEECH ENDSHERE

WordAdapter

public class WordAdapter extends ArrayAdapter<Word> { //Constructor public WordAdapter(Activity context, ArrayList<Word> word) { super(context, 0, word); } public View getView(int position, View convertView, ViewGroup parent) { // Check if the existing view is being reused, otherwise inflate the view View listItemView = convertView; if(listItemView == null) { listItemView = LayoutInflater.from(getContext()) .inflate(R.layout.item_list, parent, false); } Word CurrentWord = getItem(position); TextView spanish_text_view = (TextView) listItemView .findViewById(R.id.spanish_text_view); TextView default_text_view = (TextView) listItemView .findViewById(R.id.default_text_view); default_text_view.setText(CurrentWord.getEnglishWords()); ImageView icon = (ImageView) listItemView.findViewById(R.id.icon); icon.setImageResource(CurrentWord.getImageResourceid()); View textContainer = listItemView.findViewById(R.id.textContainer); return listItemView; } }

字

public class Word { //Varibles private String SpanishWords; //Spanish Word private String EnglishWords; //English translation of the Spanish word private int imageResourceid; private String pronunciation; public Word(String SpanishWords, String EnglishWords, int imageResourceid, String pronunciation) { this.SpanishWords= SpanishWords; //Since the name is the same use the this keyword this.EnglishWords = EnglishWords; this.imageResourceid = imageResourceid; this.pronunciation = pronunciation; } //getters public String getPronunciation() { return pronunciation; } }

所以当我点击 TextContainer 时，应该说西班牙语（这是 MainActivity class 中的第四个参数）。

这就是我目前所拥有的，但我无法让它发挥作用。每当我尝试播放该应用程序时，该应用程序都会崩溃。我真的不知道如何通过自定义 arrayAdapter 使用 Text to Speech。如果有人能指出正确的方向，我将不胜感激。我想让它直接从 MainActivity Initializing 地方的第四个参数
抓取文本

这应该有效。如果您对语言有疑问，请查看 official docs。

 textoSpeech=new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
         @Override
         public void onInit(int status) {
            if(status != TextToSpeech.ERROR) {
               textoSpeech.setLanguage(Locale.ES);
            }
         }
      });

      TextContainer.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            String toSpeak = TextContainer.getText().toString();
            Toast.makeText(getApplicationContext(),toSpeak,Toast.LENGTH_SHORT).show();
            textoSpeech.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null);
         }
      });

希望我有所帮助。

所以我设法修复了它，我所要做的就是编辑 MainActivity Java 文件像这样

MainActivity

  final ArrayList<Word> numbers = new ArrayList<Word>(); //edited this

  numbers.add(new Word("one", "onu", R.drawable._nmbericon,"unoo"));

                    WordAdapter adapter = new WordAdapter(this, numbers);
                    ListView listView = (ListView) findViewById(R.id.listview);

                    listView.setAdapter(adapter);
    //->> TEXT TO SPEECH STARTS HERE
          listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                    @Override
                    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                        textToSpeech = new TextToSpeech(NumbersActivity.this, new TextToSpeech.OnInitListener() {
                            @Override
                            public void onInit(int status) {
                                  //And edited Here
                                if (status == TextToSpeech.SUCCESS){
                                    result = textToSpeech.setLanguage(Locale.ENGLISH);
                        Word num = numbers.get(position);
                        result = textToSpeech.setLanguage(Locale.ENGLISH);
                        String toSpeak = num.getPronunciation();
                        Toast.makeText(getApplicationContext(), toSpeak, Toast.LENGTH_SHORT).show();
                        textToSpeech.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null);
                                }else{
                                    Toast.makeText(getApplicationContext(), "Not Supported in your Device", Toast.LENGTH_SHORT).show();
                                }
                            }
                        });

                    }
                });
                  //->> TEXT TO SPEECH ENDSHERE
