我怎样才能挽救意图相机拍摄的图像被用作个人资料图片？ [英] How can i save the image taken from camera intent to be used as a profile image?

问题描述

在我的应用程序，用户可以从相机拍摄的图像并作为资料图片使用。一切正常，除了当用户离开应用程序，然后返回形象不存在了。所以，我怎么可以保存图像呆在那里，甚至当用户退出应用程序？

code相机意图：

 意图cameraIntent =新意图（android.provider.MediaStore.ACTION_IM​​AGE_CAPTURE）;
            startActivityForResult（cameraIntent，CAMERA_REQUEST）;
 

和的onActivityResult ：

 保护无效的onActivityResult（INT申请code，INT结果code，意图数据）{
    如果（要求code == CAMERA_REQUEST）{
        。位图的照片=（位图）data.getExtras（）获得（数据）;
        getLayoutInflater（）膨胀（R.layout.custon_header，NULL）;
        ImageView的profimg =（ImageView的）findViewById（R.id.roundedimg）;
        profimg.setImageBitmap（照片）;
 

可能有人请帮助我呢？

感谢

解决方案

  data.getExtras（）获得（数据）。
 

只返回这将是对低质量的图像的缩略图。你必须指定在您的相机的意图所在的图像将被保存在一个位置：

 文件OUTPUTFILE =新的文件（Environment.getExternalStorageDirectory（）+/ myOutput.jpg）;意图cameraIntent =新意图（android.provider.MediaStore.ACTION_IM​​AGE_CAPTURE）;
    cameraIntent.putExtra（Intent.EXTRA_OUTPUT，outputFile.getAbsolutePath（））;startActivityForResult（cameraIntent，CAMERA_REQUEST）;
 

和你activityResult，只需使用OUTPUTFILE您的位图：

  =位BitmapFactory.de codeFILE（outputFile.getAbsolutePath（））;
 

In my app the user can take an image from the camera and use as a profile picture. Everything works, except that when the user leaves the app and returns then the image isn't there anymore. So how can I save that image to stay there even when the user exits the app?

Code for camera intent:

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

And onActivityResult:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    if (requestCode == CAMERA_REQUEST) {  
        Bitmap photo = (Bitmap) data.getExtras().get("data"); 
        getLayoutInflater().inflate(R.layout.custon_header,null);
        ImageView profimg = (ImageView) findViewById(R.id.roundedimg);
        profimg.setImageBitmap(photo);

Could someone please assist me with this?

Thanks

解决方案

data.getExtras().get("data"); 

only returns the thumbnail of the image which would be on low quality. You have to specify on your camera intent a location where the image will be saved:

File outputFile = new File(Environment.getExternalStorageDirectory() +"/myOutput.jpg");

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
    cameraIntent.putExtra(Intent.EXTRA_OUTPUT,outputFile.getAbsolutePath());

startActivityForResult(cameraIntent, CAMERA_REQUEST);

and on your activityResult, simply use the outputfile for your bitmap:

bitmap = BitmapFactory.decodeFile(outputFile.getAbsolutePath());
