mediaPlayer无法播放

Question

我正在尝试在背景音乐中构建启动画面，但是音乐无法播放。

这是我的代码：

    package com.example.thebasicseries;

import android.support.v7.app.ActionBarActivity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;  

public class MainActivity extends ActionBarActivity {
    MediaPlayer logoMusic;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);

        logoMusic = MediaPlayer.create(MainActivity.this,R.raw.techno );
        Thread logoTimer = new Thread(){
            public void run(){
                try{
                    sleep(5000);
                    Intent menuIntent = new Intent("com.example.thebasicseries.MENU");
                    startActivity(menuIntent);
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                finally{
                    finish();
                }
            }

        };
        logoTimer.start();
        logoMusic.release();
    }

在运行该应用程序之前或之后，没有任何错误消息显示。

Answer 1

大声笑，您创建了MP：

logoMusic = MediaPlayer.create(MainActivity.this,R.raw.techno ) ;

但是不要玩：

logoMusic.play(); 

Answer 2

更好的是，从视频中为启动画面剪切特定部分，并像gif图像一样使用它，它将起作用

Answer 3

我有它的工作！

    package com.example.thebasicseries;


import android.support.v7.app.ActionBarActivity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;


public class MainActivity extends ActionBarActivity {
    MediaPlayer logoMusic;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash);

        logoMusic = MediaPlayer.create(MainActivity.this,R.raw.techno );
        logoMusic.start();
        Thread logoTimer = new Thread(){
            public void run(){
                try{
                    sleep(5000);
                    Intent menuIntent = new Intent("com.example.thebasicseries.MENU");
                    startActivity(menuIntent);
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                finally{
                    finish();
                }
            }

        };
        logoTimer.start();

    }
    @Override //so i just create an onPause method and release my song

    protected void onPause() {
        // TODO Auto-generated method stub
        super.onPause();
        logoMusic.release(); //while it is onPause i release the song
    }


}
