Android相机意图：如何获取全尺寸照片？

我正在使用意图来启动相机：

Intent cameraIntent = new Intent(
    android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
getParent().startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);

并使用：

Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
photoImage.setImageBitmap(thumbnail);
photoImage.setVisibility(View.VISIBLE);

但这只是一个缩略图，如何获得完整的位图？我知道我可以使用自己的 Activity 并使用：

Camera.PictureCallback()

但是有没有办法使用 Intent 来做到这一点呢？

Thanks!

edit:

我也尝试过：

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    Uri uri = data.getData();
    imageView.setImageURI(uri);
}

它适用于从图库中选择的照片，但对于相机意图，data.getData() 返回 null。

要获得全尺寸的相机图像，您应该将相机指向将图片保存在临时文件中，例如：

    private URI mImageUri;

    Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
    File photo;
    try
    {
        // place where to store camera taken picture
        photo = this.createTemporaryFile("picture", ".jpg");
        photo.delete();
    }
    catch(Exception e)
    {
        Log.v(TAG, "Can't create file to take picture!");
        Toast.makeText(activity, "Please check SD card! Image shot is impossible!", 10000);
        return false;
    }
    mImageUri = Uri.fromFile(photo);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, mImageUri);
    //start camera intent
    activity.startActivityForResult(this, intent, MenuShootImage);

private File createTemporaryFile(String part, String ext) throws Exception
{
    File tempDir= Environment.getExternalStorageDirectory();
    tempDir=new File(tempDir.getAbsolutePath()+"/.temp/");
    if(!tempDir.exists())
    {
        tempDir.mkdirs();
    }
    return File.createTempFile(part, ext, tempDir);
}

然后在图像捕获意图完成工作后 - 只需从imageUri使用以下代码：

public void grabImage(ImageView imageView)
{
    this.getContentResolver().notifyChange(mImageUri, null);
    ContentResolver cr = this.getContentResolver();
    Bitmap bitmap;
    try
    {
        bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr, mImageUri);
        imageView.setImageBitmap(bitmap);
    }
    catch (Exception e)
    {
        Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT).show();
        Log.d(TAG, "Failed to load", e);
    }
}


//called after camera intent finished
@Override
public void onActivityResult(int requestCode, int resultCode, Intent intent)
{
    //MenuShootImage is user defined menu option to shoot image
    if(requestCode==MenuShootImage && resultCode==RESULT_OK) 
    {
       ImageView imageView;
       //... some code to inflate/create/find appropriate ImageView to place grabbed image
       this.grabImage(imageView);
    }
    super.onActivityResult(requestCode, resultCode, intent);
}

P.S.需要针对 Android M 中应用的新安全限制修改代码 -文件提供者 https://developer.android.com/reference/android/support/v4/content/FileProvider.html: mImageUri必须装满FileProvider
