android - 如何将图像转换为位图

Question

嗨，我有这段代码，如何将图像转换为位图？我正在从画廊访问图像。

_GaleryButton.setOnClickListener(new View.OnClickListener()
 {

        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent intent=new Intent();

            intent.setAction(Intent.ACTION_PICK);

               intent.setData(android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI);

               startActivity(intent);
        }
    });

}
    protected void onGActivityResult(int GrequestCode, int GresultCode, Intent Gdata){

        super.onActivityResult(GrequestCode,GresultCode,Gdata);

        Uri uriimg = Gdata.getData();


    }

Answer 2

如果要将图像获取到 sd 卡，请使用此代码

//Get the root of your sd card
File sdcard = Environment.getExternalStorageDirectory();

//Folder from sd card
File storagePath = new File(sdcard.getAbsolutePath() + "/fb_image");

//Decode the file from the folder to bitmap
Bitmap bmp = BitmapFactory.decodeFile(storagePath + "/" + file_name+ ".jpg");
