由于用户不说话而在RecognizerIntent完成时如何处理图像(ImageView)的可见性
if (RecognizerIntent.EXTRA_RESULTS == null){
image1.setVisibility(View.VISIBLE);///microphone icon
}
要么
if (RecognizerIntent.ACTION_RECOGNIZE_SPEECH == null){
image1.setVisibility(View.INVISIBLE);///microphone
}
n
最佳答案
在上面的代码中,您只是测试常量是否为null,否则是否为null。您必须通过以下方式在代码中的某处开始识别
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
//... put other settings in the Intent
startActivityForResult(intent, REQUEST_CODE);
并接收结果
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) {
ArrayList<String> results = data.getStringArrayListExtra(
RecognizerIntent.EXTRA_RESULTS);
//... do your stuf with results
}
super.onActivityResult(requestCode, resultCode, data);
}
一种更可定制的方法是直接使用SpeechRecognizer。参见例如this question。
