看到标题大家应该都知道了，本文主要实现android发送语音功能

前面几篇博客写的webSocket，notifaction和service，当然了既然是即时通讯，怎么能少了语音聊天呢。

下面先简单说下语音功能的描述，在android中针对语音功能的是通过录音发送，做过的童鞋都知道在android中录音的格式是arm，这个在android设备通讯是没有问题的，但在ios设备不能播放，因为ios设备不支持arm格式的播放，最好查了好几篇博客，最好的解决方案是转换成AAC格式，至于为什么选择aac格式，在此不做过多的解释，如果想了解的朋友可以看http://blog.csdn.net/kingkong1024/article/details/14004885

下面就直接说下aac格式：

既然要发送语音，那就比需要对录音各个方面进行处理

大家看的最多应该就是微信语音功能了

首先对button按钮进行处理和封装

import android.os.Environment;
import android.os.Handler;
import android.util.AttributeSet;
import android.view.MotionEvent;

            mDialog = null;
        }}/**
     * 通过Level更新Voice的图片：V1——V7
     * @param level
     */
    public void updateVoiceLevel(int level) {if (mDialog != null && mDialog.isShowing()) {int voiceResId=mContext.getResources().getIdentifier("v"+level, "mipmap", mContext.getPackageName());  //getIdentifier()获取应用包下指定资源的ID
            mVoice.setImageResource(voiceResId);
        }}
}

剩下的就是如何在activity中的应用和使用

主要调用封装button的回调

input_voice
                .setAudioFinishRecorderListenter(new AudioRecorderButton.AudioFinishRecorderListenter() {@Override
                    public void onFinish(float seconds, String FilePath) {                        System.out.println("======录音时间======="+seconds);
                        System.out.println("======录音acc地址===="+FilePath);
                        voiceSeconds= (int) seconds;

           //此处做的业务处理===发送语音

                        sendVoice(FilePath,1);
                    }});
