Question

以下是我拍照的代码

            File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
            String name = imageFileName;
            File file = new File(path, name);
            Toast.makeText(getBaseContext(), file.toString(), Toast.LENGTH_LONG).show();
            outputFileUri = Uri.fromFile(file);
            Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
            startActivityForResult(cameraIntent, CAMERA_REQUEST); 


}

static final int REQUEST_IMAGE_CAPTURE = 1;
protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    this.imageView = (ImageView)this.findViewById(R.id.mImageView);
    if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {  
        Bitmap photo = (Bitmap) data.getExtras().get("data"); 
        imageView.setImageBitmap(photo);
    }  

    }

这样可以拍照并在图像视图中放置缩略图

问题是它将图片保存在SD卡上的DCIM卡中时应将其保存在图片文件夹中，文件名为“Imagefilename”

toast我已将完整路径报告为

storage / emulated / 0 / Pictures / filename.jpg但是图片没有保存在那里

我在清单

中设置了读写权限

任何我出错的想法

标记

你需要这个：

cameraIntent.putExtra( MediaStore.EXTRA_OUTPUT,outputFileUri );

在调用startActivityForResult之前..所以复制上面的代码：

        File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
        String name = imageFileName;
        File file = new File(path, name);
        Toast.makeText(getBaseContext(), file.toString(), Toast.LENGTH_LONG).show();
        outputFileUri = Uri.fromFile(file);
        Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 

        cameraIntent.putExtra( MediaStore.EXTRA_OUTPUT,outputFileUri );// add this

        startActivityForResult(cameraIntent, CAMERA_REQUEST);

android相机不保存图片
