如何制作不同的按钮，不同的图像视图会受到影响

Question

我对这个编码很陌生，我希望你们中的任何人都可以帮助我解决这个问题。基本上我有三个具有不同图像视图的不同按钮，我想将它们上传到我的 MySQL。但是，当我在不同时间按下所有三个按钮时，它只会影响图像视图中的 1 个。如果您能提供帮助，不胜感激。

    public static final int resultloadimage = 1;
    private static final int RESULT_OK = -1;

    Button btnupadloadnric, btnuploaddl, btnuploadvl,updateButton;

    EditText fullanme, telephone;

我认为您应该在每次按钮点击时更改每个图库意图的请求代码。

btnuploadvl.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent gallery = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(gallery, "request code for btnuploadvl");
        }
    });
    btnuploaddl.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent gallery = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(gallery, "request code for btnuploaddl");
        }
    });
    btnupadloadnric.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent gallery = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(gallery, "request code for btnupadloadnric");

        }
    });

然后检查请求代码，检测onActivityResult上点击了哪个按钮。
