Android錄制聲音文件（音頻），並播放

readme：1、這個demo中沒有對多次點擊同一個聲音文件做詳細處理，偶爾會有崩潰，用的時候需要注意。2、按住錄音按鈕錄音過程中，只對豎直方向處理了一下，水平方向沒寫；3、沒有做刪除某個聲音文件的操作，但是測試的時候實現了功能，需要用到的話，在MainActivity—>onItemClick中的TODO中有詳細說明；4、這只是個demo，如果要在項目中使用，先寫出demo，沒問題了，再引入項目，在寫成demo後，在真機上運行的時候，如果出現獲取錄音權限，最好選擇“允許”，如果拒絕，可能會崩潰。

記得打開手機運行錄音的權限
先來效果圖：

目錄結構：

1、添加權限：<喎?/kf/ware/vc/" target="_blank" class="keylink">vcD4NCjxwcmUgY2xhc3M9"brush:java;">

2、新建MediaRecorderUtils，復制以下源碼：

        }

    }

     */

}

6、activity_main布局

7、voice_popupwindow布局代碼：錄音的時候，會出現以下圖片中的popupwindow

8、還有一個動畫布局，播放聲音的時候，有個動畫效果

附錄：用到的圖片資源說明：如果手上沒有這樣的圖片，可以隨便用其他圖片代替，有效果，就算成功
