我是 Android 开发新手。

我需要在 Android 设备上录制视频。当我搜索它时，我没有找到任何有效的正确代码。即使android开发人员也没有提供清晰的代码..

如果有人有链接或代码，请与我分享..

谢谢..

在 xml 文件中放置一个按钮，在其中要打开相机进行视频录制。

我在这里放置了视频重新编码代码。

这将在您的 SD 卡/中创建一个文件夹，或者如果未插入 SD 卡，它将使用系统内存。希望你知道……我不需要对此做太多解释。

然后将下面的点击侦听器映射到您在 xml 中设计的按钮，

    Button recordButton = 
            (Button) findViewById(R.id.CaptureVid);
    recordButton.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View arg0) {

    String timestamp="1";
    String  timestamp = new SimpleDateFormat("MM-dd-yyyy_HH-mm-ss aa").format(Calendar.getInstance().getTime());
    File filepath = Environment.getExternalStorageDirectory();
    File dir = new File(filepath.getAbsolutePath()+ "/samplevideofolder/");
    dir.mkdirs();
    File mediaFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/samplevideofolder/Video_"+timestamp+".avi");  
    Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
    Uri fileUri = Uri.fromFile(mediaFile);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
    intent.putExtra(MediaStore.EXTRA_DURATION_LIMIT, 30); 
    startActivityForResult(intent, VIDEO_CAPTURE);
        }
    });

将此代码放在下面的某处，作为主类中的函数，

protected void onActivityResult(int requestCode, int resultCode, Intent data) {


    if (requestCode == VIDEO_CAPTURE) {
      if (resultCode == RESULT_OK) {



         Toast.makeText(this, "Video saved to:\n" +data.getData(), Toast.LENGTH_LONG).show();



      } else if (resultCode == RESULT_CANCELED) {
            Toast.makeText(this, "Video recording cancelled.",  Toast.LENGTH_LONG).show();
      } else {
         //Toast.makeText(this, "Failed to record video",                        Toast.LENGTH_LONG).show();
        }
    }
}

就是这样，您就完成了视频录制。

在上面的代码中，您可以找到这样的行。

intent.putExtra(MediaStore.EXTRA_DURATION_LIMIT, 30);

这将在 30 秒后自动停止视频,,,
如果你想录制超过这个时间的视频，无限时间..只需评论该行..好的

Put a button in xml file, where you want open the camera for video recording.

here by i put the video recoding code.

this will create a folder in your sdcard/ or if no sdcard inserted it will use sytem inbult memory. hope u ll know..i dont need to explain a lot on this.

then map the below on click listener to the button you designed in your xml

    Button recordButton = 
            (Button) findViewById(R.id.CaptureVid);
    recordButton.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View arg0) {

    String timestamp="1";
    String  timestamp = new SimpleDateFormat("MM-dd-yyyy_HH-mm-ss aa").format(Calendar.getInstance().getTime());
    File filepath = Environment.getExternalStorageDirectory();
    File dir = new File(filepath.getAbsolutePath()+ "/samplevideofolder/");
    dir.mkdirs();
    File mediaFile = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/samplevideofolder/Video_"+timestamp+".avi");  
    Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
    Uri fileUri = Uri.fromFile(mediaFile);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
    intent.putExtra(MediaStore.EXTRA_DURATION_LIMIT, 30); 
    startActivityForResult(intent, VIDEO_CAPTURE);
        }
    });

put this code somewhere below , as function inside the main class

protected void onActivityResult(int requestCode, int resultCode, Intent data) {


    if (requestCode == VIDEO_CAPTURE) {
      if (resultCode == RESULT_OK) {



         Toast.makeText(this, "Video saved to:\n" +data.getData(), Toast.LENGTH_LONG).show();



      } else if (resultCode == RESULT_CANCELED) {
            Toast.makeText(this, "Video recording cancelled.",  Toast.LENGTH_LONG).show();
      } else {
         //Toast.makeText(this, "Failed to record video",                        Toast.LENGTH_LONG).show();
        }
    }
}

thats it, you are done with video recording..

in the above code you can find a line like this.

intent.putExtra(MediaStore.EXTRA_DURATION_LIMIT, 30);

this will automatically stops the video after 30 seconds,,,
if you want to record the video for more than that, unlimietd time.. just comment that line.. ok
