Android仿微信发送语音消息的功能及示例代码

微信的发送语音是有一个向上取消的，我们使用ontouchlistener来监听手势，然后做出相应的操作就行了。

直接上代码：

//语音操作对象
private mediaplayer mplayer = null;
private mediarecorder mrecorder = null;
//语音文件保存路径
private string filename = null;
filename = environment.getexternalstoragedirectory().getabsolutepath() + "/soundrecord/amrsend.amr";

定义一个imageview，然后给它设置监听事件：

@override
public boolean ontouch(view view, motionevent motionevent) {
  switch (motionevent.getaction()) {
    case motionevent.action_down:
      beginx = motionevent.getx();
      beginy = motionevent.gety();
      log.e("mainactivity", "beginx:" + beginx);
      log.e("mainactivity", "beginy:" + beginy);
      log.e("mainactivity", "action_down");
      mrecorder = new mediarecorder();
      mrecorder.setaudiosource(mediarecorder.audiosource.mic);
      mrecorder.setoutputformat(mediarecorder.outputformat.three_gpp);
      mrecorder.setoutputfile(filename);
      mrecorder.setaudioencoder(mediarecorder.audioencoder.amr_nb);
      try {
        mrecorder.prepare();
      } catch (ioexception e) {
        log.e("mainactivity", "prepare() failed" + e);
      }
      mrecorder.start();
      break;
    case motionevent.action_up:
      finalx = motionevent.getx();
      finaly = motionevent.gety();
      log.e("mainactivity", "finalx:" + finalx);
      log.e("mainactivity", "finaly:" + finaly);
      log.e("mainactivity", "action_up");
      mrecorder.stop();
      mrecorder.release();
      mrecorder = null;
      if ((beginy - finaly) > 50) {
        log.e("mainactivity", "执行删除");
        new file(filename).delete();
        log.e("mainactivity", "执行删除后文件是否还存在：" + new file(filename).exists());
      }
      break;
    default:
      break;
  }
  return true;
}

然后在清单文件中加上需要的权限就行了：

<uses-permission android:name="android.permission.write_external_storage" />
<uses-permission android:name="android.permission.mount_unmount_filesystems" />
<uses-permission android:name="android.permission.read_external_storage" />
<uses-permission android:name="android.permission.record_audio" />

也可以在按下之后播放动画，显示正在录音，然后在抬起动作之后结束动画，这样就比较形象了。
