所有你需要知道的:我有一个带有按钮的对话框.按下按钮时,我想在MainActivity中启动语音识别.(该对话框由另一个类创建,我通过界面处理点击).

所以这是相关的代码:(在MainActivity中)

public void speechToText(boolean isName) {

    this.isName = isName;

    Intent intent = new Intent(
            RecognizerIntent.ACTION_RECOGNIZE_SPEECH);

    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault().toString());
    //intent.putExtra(RecognizerIntent.EXTRA_PROMPT, getString(R.string.prompt));

    try {
        startActivityForResult(intent, RESULT_SPEECH);

        Toast.makeText(getApplicationContext(),
                "started acitvity for result",     //test toast
                Toast.LENGTH_SHORT).show();

    } catch (ActivityNotFoundException a) {
        Toast.makeText(getApplicationContext(),
                getString(R.string.speech_to_text_not_supported),
                Toast.LENGTH_SHORT).show();
    }
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    switch (requestCode) {
        case RESULT_SPEECH: {
            if (resultCode == RESULT_OK && null != data) {

                ArrayList<String> text = data
                        .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

                if(isName)
                    currentName = text.get(0);
                else …
