如何在单击按钮时开始活动以生成喷气背包的结果

Question

实现在Java，想在Jetpack这个实现上写一个图标点击。按钮单击以显示语音到文本对话框：

mVoiceBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            speak();
        }
    });

主要问题是在compose中创建这个特定的Intent：

private void speak() {
        //intent to show speech to text dialog
        Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        intent.putExtra(
                RecognizerIntent.EXTRA_LANGUAGE_MODEL
                , RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
        intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Hi Speak Somethimh");

        //start intent
        try {
            //in there was no error
            //show dialog
            startActivityForResult(intent, REQUEST_CODE_SPEECH_INPUT);
        } catch (Exception e) {

            //IF THERE WERE SOME ERROR
            //GET MESSAGE OF ERROR AND SHOW
            Toast.makeText(this, "" + e.getMessage(), Toast.LENGTH_SHORT).show();
        }
    }

    //receive voice input and handle it
    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        switch (requestCode) {
            case REQUEST_CODE_SPEECH_INPUT: {
                if (resultCode == RESULT_OK && null != data) {
                    //GET TEXT ARRAY FROM VOICE INTENT
                    ArrayList<java.lang.String> result;
                    result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
                    // SRT TO TEXT VIEW
                    mTextTv.setText(result.get(0));
                }
                break;
            }
            default:
        }
    }

记住结果的启动器活动和启动未决意图是我能找到的解决方案，可能有更好的方法。

        val intent = Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH)
        intent.putExtra(
            RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM
        )
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault())
        intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Hi Speak Somethimh")
        val context = LocalContext.current

        val pendIntent = PendingIntent.getActivity(context, 0, intent, 0)
        var code by remember {
            mutableStateOf("")
        }
        val launcher = rememberLauncherForActivityResult(
            contract = ActivityResultContracts.StartIntentSenderForResult()
        ) {
            if (it.resultCode != RESULT_OK) {
                return@rememberLauncherForActivityResult
            }

            //GET TEXT ARRAY FROM VOICE INTENT
            val result = it.data?.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS)

            if (result !== null) {
                code = result[0] ?: ""

            }
        } 

Button(onClick = {
                launcher.launch(
                    IntentSenderRequest.Builder(pendIntent)
                        .build()
                )
            }) {
                
 }
