如何將圖像轉換為位圖

Question

嗨，我有這段代碼，如何將圖像轉換為位圖？ 我正在從畫廊訪問圖像。

_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

如果要將圖像保存到SD卡，請使用此代碼

//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");
