錄音時間過短顯示不正常
為什么顯示“錄音時間過短”有問題呢？求解，謝謝了！log執(zhí)行到了，就是對話框顯示不正常，顯示的是Normal狀態(tài)

你好，看完了你的代碼沒有發(fā)現(xiàn)問題，建議再次檢查下布局文件和代碼。
2015-09-02
isReady聲明時初始化為false就行了
2015-06-20
你在prepareAudio()里面少一行代碼。沒i有設(shè)置文件輸出 ??mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
//設(shè)置輸出文件
mMediaRecorder.setOutputFile(file.getAbsolutePath());
