Question

我已经在本网站上查看了几个关于我的问题的回答问题，但是无法让这个问题起作用。我试图让按钮在点击后播放声音。

Java代码：

package jg.AvengersSoundboard;

import android.app.Activity;
import android.os.Bundle;

public class Activity2 extends Activity {
    private Object mp;
    /** Called when the activity is first created. */
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main2);
    }
}

XML代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

Answer 1

您需要将声音文件存储在res / raw / beep.mp3

中

private MediaPlayer mp;

在按钮点击事件

上添加此项

    mp = MediaPlayer.create(this, R.raw.beep);
    mp.start();//to start playing the sound

停止

    mp.stop();

Answer 2

首先，您必须使用XML中的按钮ID创建按钮的Object 像这样的文件：

Button one = (Button)this.findViewById(R.id.button1);
Button two = (Button)this.findViewById(R.id.button2);
Button zero = (Button)this.findViewById(R.id.button3);

......对其他人来说......

现在创建一个media player的实例变量，如下所示：

MediaPlayer mp;

现在在你的OnCreate方法上写下这个：

mp = MediaPlayer.create(this, R.raw.mamacita_zero/*Your Sound file in raw folder*/);

现在为你的按钮设置一个onClickListener：

zero.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mp.start();
            }
        });

在每个按钮上，您可以使用相同的方法播放声音。

单击按钮播放声音
