我创建了一个视频录制应用。在按钮上单击它将开始录制并结束。一旦它结束，我可以毫无问题地再次开始录制。
我的问题是在完成上一条记录之前单击按钮：应用程序获得强制关闭对话框。
如果在完成录制之前单击按钮，我想要停止录制。
这是我的代码
public void StrBtnClick1(View view) throws IOException
{
try {
startRecording();
new Thread(new Runnable() {
private int progressStatus = 0;
public void run() {
while (progressStatus < 100 ) {
progressStatus += 1;
// Update the progress bar and display the current value in the text view
handler.post(new Runnable() {
public void run() {
progressBar.setProgress(progressStatus);
}
});
try {
Thread.sleep(150);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
release();
flage = 2;
//releaseMediaRecorder();
}
}).start();
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Camera not available111!", Toast.LENGTH_LONG).show();
release1();
flage=2;
}
}
public void ChangeBtnClick(View view) throws IOException
{
//Changecamera();
}
protected void startRecording() throws IOException
{
mrec = new MediaRecorder(); // Works well
if (flage==1){
mCamera.unlock();
mrec.setCamera(mCamera);
}
mrec.setPreviewDisplay(surfaceHolder.getSurface());
mrec.setVideoSource(MediaRecorder.VideoSource.CAMERA);
mrec.setAudioSource(MediaRecorder.AudioSource.MIC);
mrec.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));
mrec.setPreviewDisplay(surfaceHolder.getSurface());
mrec.setMaxDuration(15000);
mrec.setOutputFile("/sdcard/Myvideo.MP4");
mrec.prepare();
mrec.start();
}

}

}
}

}
}
