如何使相机出现在特定的屏幕区域的Andr​​oid？

问题描述

我需要相机出现在这里的android特定的屏幕面积是code，我用相机活动

现在摄像头的工作，但它占据整个屏幕，我想相机出现在屏幕的particulat面积如何做到这一点？

 私人无效uploadPhoto（字符串名称）{
        意向意图=新意图（MediaStore.ACTION_IM​​AGE_CAPTURE）;
        档案文件=新的文件（Environment.getExternalStorageDirectory（），名称
                +.JPG）;
        mImageCaptureUri = Uri.fromFile（文件）;
        尝试{
            intent.putExtra（android.provider.MediaStore.EXTRA_OUTPUT，
                    mImageCaptureUri）;
            intent.putExtra（回归数据，真正的）;
            startActivityForResult（意向，PICK_FROM_CAMERA）;
        }赶上（例外五）{
            e.printStackTrace（）;
        }    }
 

解决方案

您不能使用此意图。如果您使用的意图，它西港岛线启动相机应用。相反，你需要使用一种叫做相机preVIEW。这将显示摄像头看到用户什么，然后你可以使用API​​的控制摄像头的动作。

在这里是一个非常好的教程，这从官方开发人员文档：

I need camera to appear in particular screen area in android here is the code that I use for camera activity

Now camera is working but it occupies whole screen I want camera to appear in particulat area of screen how to do this??

 private void uploadPhoto(String name) {
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        File file = new File(Environment.getExternalStorageDirectory(), name
                + ".jpg");
        mImageCaptureUri = Uri.fromFile(file);
        try {
            intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,
                    mImageCaptureUri);
            intent.putExtra("return-data", true);
            startActivityForResult(intent, PICK_FROM_CAMERA);
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

解决方案

You cannot use an intent for this. If you use an intent, it wil launch the camera app. Instead, you need to use something called a Camera Preview. This will show what the camera sees to the user and you can then use API's to control the camera actions.

here is a very nice tutorial for this from the official developer docs:https://developer.android.com/guide/topics/media/camera.html#custom-camera
