Question

我是 Android 的新人，正在开发语音转文本应用程序。我正在使用 Google API。我想让用户只能说2秒。 2 秒后弹出 window 应该关闭。谁能给我一些提示？

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mic.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            promptSpeechInput();
        }
    });
}

public void promptSpeechInput()
{
    //This intent recognize the speech
    Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    i.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
    i.putExtra(RecognizerIntent.EXTRA_PROMPT, "Say Something");

    try {
        startActivityForResult(i, 100);
    }
    catch (ActivityNotFoundException a)
    {
        Toast.makeText(MainActivity.this,"Your device does not support",Toast.LENGTH_LONG).show();
    }
}

//For receiving speech input
public void onActivityResult(int request_code, int result_code, Intent i)
{
    super.onActivityResult(request_code, result_code, i);

    switch (request_code)
    {
        case 100: if(result_code == RESULT_OK && i != null)
        {
            ArrayList<String> result = i.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
            resultTEXT.setText(result.get(0));
        }
            break;
    }
}

Answer 1

您可以在要启动计时器的地方添加此代码，并且在方法中运行您必须编写关闭弹出窗口的代码

new java.util.Timer().schedule( 
    new java.util.TimerTask() {
        @Override
        public void run() {
            // your code here
        }
    }, 
    5000 
);

此处为 5 秒（5000 毫秒），您可以将其更改为您需要的任何时间段（以毫秒为单位）。

在 UIThread 中尝试 Handler 这可以让您在弹出窗口 window 关闭时延迟..添加代码以在运行():

中关闭弹出窗口

runOnUiThread(new Runnable() {
            @Override
            public void run() {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        //close the window pop-up here
                    }
                }, 2000);
            }
        });
