Question

我想改变这个开关，以便不是点击按钮，而是通过说出相关水果的名称来启动我的活动。例如，Apple类将通过说出“Apple”这个词来发布。我该如何重写这个开关？到目前为止，我所做的所有尝试似乎都没有奏效。任何答案将不胜感激。谢谢！

                // create an intent indicating we want
                // to start the activity.

                            Intent i = new Intent(this, Apple.class);
                // start the activity based on the Intent

                    break;

            case R.id.five:
                    Intent m = new Intent(this, Strawberry.class);

                    // start the activity based on the Intent
                    startActivityForResult(m, 0);
                    finish();
                    break;

            case R.id.six:
                    Intent n = new Intent(this, Kiwi.class);

                    // start the activity based on the Intent
                    startActivity(n);
                    finish();
                    break;
                    default:
                    finish();
        }

    };
}

这是处理语音活动结果的正确方法吗？

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

            //If Voice recognition is successful then it returns RESULT_OK
            if(resultCode == RESULT_OK) {

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

                if (!textMatchList.isEmpty()) {
                    // If first Match contains the word 'apple'
                    // Then start the apple activity.
                    if (textMatchList.get(0).contains("apple")) {
                            // create an intent indicating we want
                // to start the activity.

                            Intent i = new Intent(this, Apple.class);
                // start the activity based on the Intent
                startActivity(i);
                finish();
                break;

我觉得这条线后有些东西不见了......

if (textMatchList.get(0).contains("apple")) {

Here是有关如何使用Android语音识别的示例教程。您需要在OnActivityResult中处理搜索结果并对apple，banana，grape等进行字符串匹配..如果找到字符串匹配，则启动相应的活动！
