Question

在TextView中使用文字转语音在方括号中显示识别文字。

如何删除它们？

例如：而不是：car - [car]

 public class MainActivity extends AppCompatActivity implements View.OnClickListener {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button recognizeButton = (Button)findViewById(R.id.button1);
        recognizeButton.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "You may speak!");
        intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.ENGLISH);
        startActivityForResult(intent, 1);
    }

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

        if (requestCode == 1 && resultCode == RESULT_OK) {
            ArrayList<String> results;
            results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
                TextView speechText = (TextView) findViewById(R.id.textView1);
                speechText.setText(results.toString());          
        }
    }
}

Answer 1

结果以ArrayList<String>的形式返回。如果您只想要返回列表的第一个元素，请按get(0)获取，请参阅http://developer.android.com/reference/java/util/ArrayList.html

如果您希望打印结果但不喜欢toString()的输出，请使用例如join

Answer 2

尝试关闭该行 //intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);

并将最后一个更改为 speechText.setText(results.get(0)); - 0返回ArrayList

中的第一个单词
