Post 15: Media Player Android App

Today I want to present you a Vietnamese dialect game. If you press the "Play" Button you'll hear a short sentence in one of Vietnamese dialect.

 

In the spinner below you choose one of the options and then press the "Submit" Button. If it is true it will add up to your score, other wise not.

 

Here's an example on how to use it:

 

This App will use among other the MediaPlayer and the spinner feature. In this Blog post, I'll only talk about these features because I haven't talked about them in any of my post yet.The activation of Buttons I have explained earlier in this post already.

First create a folder "raw" in the "res" folder. In the "raw" folder put all of your audio files:

In the MainActivity.java file put the following code (as you can see I didn't include all variables, because I wanted to keep the code short and concentrate on the featuares I haven't talked about in my Blog):

    public void onCreate(Bundle savedInstanceState) {
        try{
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

// Set the ClickListener:
        play_button.setOnClickListener(this);
        pause_button.setOnClickListener(this);
        btnSubmit.setOnClickListener(this);
// Set path to media 
        player = MediaPlayer.create(this, R.raw.v01);

seek_bar.setMax(player.getDuration());       
        }catch(NullPointerException e){
            Log.v(getString(R.string.app_name), e.getMessage());
        }
    }

Runnable run = new Runnable() {
 
        @Override
        public void run() {
            seekUpdation();
        }
    };

public void seekUpdation() {
        seek_bar.setProgress(player.getCurrentPosition());
        seekHandler.postDelayed(run, 1000);
    }
 

public void onClick(View view) {
        Intent serv=new Intent(this,MuzakService.class);
       
        switch (view.getId()) {
        case R.id.play_button:
            text_shown.setText("Playing...");
            player.start();
            startService(serv);           
            break;
        case R.id.pause_button:
            player.pause();
            text_shown.setText("Paused...");
            break;
        case R.id.btnSubmit:
            tries++;
         String item = spinner1.getSelectedItem().toString();
         if (item.equals(dialect)){
          score++;
          quota=(float) (score/(tries*1.0))*100;
          text_score.setText("Accurate! New Score: "+quota+"% accuracy out of "+tries+" trials.");
          }
         else{
          quota=(float) (score/(tries*1.0))*100;
          text_score.setText("Are you deaf?! New Score: "+quota+"% accuracy"+tries+" trials.");
         }
         btnSubmit.setEnabled(false);
         break; }
