您可以选择相机或画廊的图像 [英] Choose an image from camera or gallery

问题描述

我怎样才能为用户提供了选择从相机或画廊图像的选项和检索资源ID相关联的？

How can I offer the user the option of choosing an image from the camera or gallery and retrieve the Resource id associated?

推荐答案

试试这个作为一个意向

Intent i = new Intent(Intent.ACTION_PICK,
           android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, ACTIVITY_SELECT_IMAGE);

下面是你如何retreive返回的图像。

Here is how you retreive the returned image.

protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) { 
super.onActivityResult(requestCode, resultCode, imageReturnedIntent); 

switch(requestCode) { 
case REQ_CODE_PICK_IMAGE:
    if(resultCode == RESULT_OK){  
        Uri selectedImage = imageReturnedIntent.getData();
        String[] filePathColumn = {MediaStore.Images.Media.DATA};

        Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String filePath = cursor.getString(columnIndex);
        cursor.close();


        Bitmap yourSelectedImage = BitmapFactory.decodeFile(filePath);
    }
}
}
