推荐答案

您首先需要启动一个活动询问用户选择一个图片。接下来需要处理的选择的结果。

You first need to start an Activity which asks the user to pick a picture. You next need to handle the result of that choice.

1：选择图片

Intent choosePictureIntent = new Intent(MediaStore.ACTION_PICK, Images.Media.INTERNAL_CONTENT_URL);
startActivityForResult(choosePictureIntent, REQUEST_CHOOSE_IMAGE);

2：处理活动的结果

2: Handle the result of the Activity

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CHOOSE_IMAGE) {
        if (resultCode == RESULT_OK) {
            // send picture to Internet
        }
    }
}

究竟如何你发送的图片是一个完全独立的问题。

How exactly you send the picture is a completely separate question.
