Question

我正尝试通过google TTS语音合成器大声朗读印地文文本，由于我已经手动安装了印地文语音数据，因此在我的设备上运行良好，但是在另一台不包含印地文语音的设备上进行测试时，它没有显示下载特定语音数据的提示。这是部分代码：

<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<style>
  i{color:#000;font-size:30px!important}
  .blueColor{color:#118de8}
</style>
<script>
$(document).ready(function(){
    $("i").click(function(){
        $(this).toggleClass("blueColor");
    });
});
</script>
</head>
<body>

<i class="fa fa-chain-broken" aria-hidden="true"></i>

</body>
</html>

因此，@Override protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) { if (requestCode == ACT_CHECK_TTS_DATA) { if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) { // Data exists, so we instantiate the TTS engine textToSpeech = new TextToSpeech(this, this); } else { // Data is missing, so we start the TTS // installation process Intent installIntent = new Intent(); installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA); startActivity(installIntent); } } }似乎无法正常工作，但是我不知道它到底在做什么，我相信其余的代码很好。我的问题有解决办法吗？

使用以下方法来检查是否安装了可用的语言。

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
   super.onActivityResult(requestCode, resultCode, data);

   if (requestCode == VOICE_DATA_CHECK) {
    ArrayList<String> availableLanguages = 
   data.getStringArrayListExtra(TextToSpeech.Engine.EXTRA_AVAILABLE_VOICES);

     if (availableLanguages.isEmpty()) {
      // no language data available, prompt for install
     Intent installIntent = new Intent();
      installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
      startActivity(installIntent);
     } else {
     // some language data is available, create TTS instance
      mTts = new TextToSpeech(this, this);
   }
  }
}
