I want to create simple app where I can take a photo and pass this photo and after that close camera and pass this photo to another activity. I don't know how can I start. Can you give me some examples how can I do that in easy way?

推荐答案

要捕捉图像：
    INT CAMERA_REQUEST = 1888;

To capture image: int CAMERA_REQUEST = 1888;

    Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    cameraIntent.putExtra("putSomething", true);
    startActivityForResult(cameraIntent, CAMERA_REQUEST);

获取图像焕的照片通过捕获的onActivityResult：

Get image whan photo captured through onActivityResult:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {  
        this.photo = (Bitmap) data.getExtras().get("data");
    }
}

您可以通过将照片转换成字节数组传递照片并通过意图

You can pass photo by converting photo into byte array and pass through intent

    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    photo.compress(Bitmap.CompressFormat.PNG, 90, stream);
    byte[] image = stream.toByteArray();

    Intent intent = new Intent(this, YourActivity.class);
    intent.putExtra("photo", image);
    startActivity(intent);
