我是Android新手,正在处理语音应用程序。我使用的是Google API。我想让用户只能说2秒钟。 2秒后弹出窗口应该关闭。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;
    }
}

您可以将此代码添加到要启动计时器的位置,在方法运行中,您必须编写用于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 
);

这是5秒(5000毫秒),您可以将其更改为您所需的任何时间段(以毫秒为单位)。

在UIThread中尝试使用Handler,这可以让你在弹出窗口关闭时延迟..添加代码以关闭run()中的弹出窗口:

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