mediaPlayer不播放

Question

我想在后台创建一个带有音乐的闪屏，但音乐不播放。

这里是我的代码：

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(); 
    } 

没有之前或在运行该应用程序后显示的错误信息。

Answer 1

LOL，你创建的MP：

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

但从来没有发挥它：

logoMusic.play(); 

Answer 2

更好地从视频削减特定部分的闪屏，并使用它像GIF图片，将工作

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 
    } 


}
