Android-一段时间后终止意图

Question

I am new at Android and working on a speech to text app. I am using Google API. I want to allow users can only speak 2 seconds. After 2 seconds pop-up window should close. Can anyone give me some tips?

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

You can add this code where you want to start the timer and in method run you have to write the code for closing the pop up

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

Here it is 5 seconds (5000 milliseconds) you can change it to whatever time period you required in milliseconds.

Answer 2

Try Handler inside UIThread this lets you delay when the pop-up window closes..add the code to close the pop-up in run():

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

hope it helps
