                recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
                recorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);

                recorder.setOutputFile(audiopath);

                    e.printStackTrace();
                }


                 recorder.start();   // Recording is now started

                 new RecordActivity().execute(); //waiting

                 recorder.stop();
                 recorder.reset();   
                 recorder.release(); 
            }
            stop_rec = false;
        }
    };

    //@Override
    OnClickListener stopRecord = new OnClickListener() {
        public void onClick(View v) {
            stop_rec = true; //for stop recording
        }
    };`

嗨，我的问题在 recorder.setAudioSource(MediaRecorder.AudioSource.MIC) 的行上，它会生成一些 RuntimeException。

更多细节我看不到，因为还有另一个错误：“类文件编辑器，找不到源：源附件不包含文件 InvocationTargetException.class 的源......”

有谁能够帮我？

有没有加

<uses-permission android:name="android.permission.RECORD_AUDIO"/>

在清单中？

不要忘记设置录制音频的权限

<uses-permission android:name="android.permission.RECORD_AUDIO"></uses-permission>
