在片段内使用Mediaplayer [英] Using Mediaplayer within a Fragment

问题描述

我仍在尝试理解片段及其工作方式.我有一个使布局夸大的片段.按按钮时，我试图播放声音，但遇到媒体播放器的一些问题.

I'm still trying to understand fragments and how they work. I have a fragment that inflates a layout. I am trying to play a sound when a button is pushed but I am coming across some problems with the mediaplayer.

代码是:

private void playSound(int resId) {
    MediaPlayer mp = MediaPlayer.create(Tab1Fragment.this, resId);
    mp.setOnCompletionListener(Tab1Fragment.this);
    mp.start();
}

错误是: MediaPlayer类型的create(Context，int)方法不适用于参数(Tab1Fragment，int)

我尝试使用 getApplicationContext()无济于事.

感谢您的帮助谢谢

推荐答案

在您的片段类的onCreateView方法中使用此代码，它将可以正常工作.

Use this code in onCreateView method of your fragment class and it will be working fine.

mp = MediaPlayer.create(getActivity, R.raw.songname);

现在，您可以在按钮单击侦听器上将其称为start方法.确保将 MediaPlayer mp; 设为片段类的全局变量，以便以后使用.

Now you can call it's start method on your button click listener. Make sure to make the MediaPlayer mp; global for fragment class so you can use it afterwards.
