Question

我是Java新手。如您所见，此代码阻止了ui线程。当它运行时，应用程序冻结直到完成运行（它不会弹出ANR）我需要在此代码运行时为进度按钮设置动画。有什么想法吗？

 @RequiresApi(api = Build.VERSION_CODES.KITKAT)
    public void onSpeechButtonClicked (View v) {
        TextView outputMessage = this.findViewById(R.id.outputMessage);
        EditText speakText = this.findViewById(R.id.speakText);

        try {
            // Note: this will block the UI thread, so eventually, you want to register for the event
            SpeechSynthesisResult result = synthesizer.SpeakText(speakText.getText().toString());
            assert(result != null);

            if (result.getReason() == ResultReason.SynthesizingAudioCompleted) {
                ((LoadingButton) findViewById(R.id.button_test)).stopLoading("SPEAK");
                outputMessage.setText("Speech synthesis succeeded.");
                System.out.println("Synthesis succeeded.");}

            else if (result.getReason() == ResultReason.Canceled) {
                String cancellationDetails =
                        SpeechSynthesisCancellationDetails.fromResult(result).toString();
                ((LoadingButton)findViewById(R.id.button_test)).stopLoading("There was a problem...");
                outputMessage.setText("Error synthesizing. Error detail: " +
                        System.lineSeparator() + cancellationDetails +
                        System.lineSeparator() + "Did you update the subscription info?");
            }

            result.close();
        } catch (Exception ex) {
            Log.e("SpeechSDKDemo", "unexpected " + ex.getMessage());
            assert(false);
        }
    }

您可以在代码中使用asynctasks。另外，您可以在runOnUiThread（）中使用可运行线程或新线程。将不会提供任何代码，因为Internet中有很多示例。

感谢Johny Deph，这就是我修复代码的方式。希望其他人也能找到帮助。

 @RequiresApi(api = Build.VERSION_CODES.KITKAT)
    public void onSpeechButtonClicked (View v) {
        final TextView outputMessage = this.findViewById(R.id.outputMessage);
        final EditText speakText = this.findViewById(R.id.speakText);
        Thread t = new Thread(new Runnable() {
            @Override
            public void run() {
                synchronized (this){
                    try {
                        
                        SpeechSynthesisResult result = synthesizer.SpeakText(speakText.getText().toString());
                        assert(result != null);

                        if (result.getReason() == ResultReason.SynthesizingAudioCompleted) {
                            ((LoadingButton) findViewById(R.id.button_test)).stopLoading("SPEAK");
                            outputMessage.setText("Speech synthesis succeeded.");
                            System.out.println("Synthesis okuur started.");}

                        else if (result.getReason() == ResultReason.Canceled) {
                            String cancellationDetails =
                                    SpeechSynthesisCancellationDetails.fromResult(result).toString();
                            ((LoadingButton)findViewById(R.id.button_test)).stopLoading("There was a problem...");
                            outputMessage.setText("Error synthesizing. Error detail: " +
                                    System.lineSeparator() + cancellationDetails +
                                    System.lineSeparator() + "Did you update the subscription info?");
                        }

                        result.close();
                    } catch (Exception ex) {
                        Log.e("SpeechSDKDemo", "unexpected " + ex.getMessage());
                        assert(false);
                    }

                }
            }
        });
        t.start();

如何获得此代码以在单独的线程上运行？
