ImageButton的音板Android应用程序 [英] ImageButton Soundboard android app

问题描述

我刚刚开始我的第一个音板。基本上，这是我迄今为止（除非我有40个声音）。有谁知道一个更好的方式来做到这一点？我得去赴约，但我会回来的今天晚些时候做出回应。谢谢你，谁可以提供帮助。

I'm just starting out with my first soundboard. Basically this is what I have so far (except I have 40 sounds). Does anyone know a better way to do this? I have to go to an appointment, but I will be back later today to respond. Thank you, anyone who can help.

推荐答案

以40个按钮，你需要安排这种情况发生在一个循环。

With forty buttons you need to arrange for this to happen in a loop.

虽然还有更聪明的方法可以做到这一点，你可以通过构建启动地图：

Although there are even more clever ways to do this, you can start by building a Map:

Map<Integer, Integer> map = new HashMap<Integer, Integer>>();
map.put(R.id.button1, R.raw.sound1);
map.put(R.id.button2, R.raw.sound2);
   ...

和然后循环：

for (Map.Entry<Integer, Integer> entry : map.entrySet()) {
    final MediaPlayer sound = MediaPlayer.create(entry.getValue());
    Button button = (ImageButton) findViewById(entry.getKey());
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            sound.start();
        }
    });
}

这会给你的循环液的味道。您还需要考虑如何管理你的的MediaPlayer 实例。

This will give you a taste of a looping solution. You also need to consider how you manage your MediaPlayer instances.
