Android：如何从 ImageView 上传照片？

Question

大家好，当我单击按钮rent 时，如何将图像上传到我的虚拟主机上的文件管理器？到目前为止，我还没有开始做任何事情，因为我尝试按照从画廊上传的方式上传它，但它没有用。你们能帮帮我吗？到目前为止，我清理了我的代码，就是这样

@Override
public void onClick(View v) {



    HashMap postData = new HashMap();

    postData.put("txtCarModel", tvCarModel.getText().toString());
    postData.put("txtCarType", tvCarType.getText().toString());
    postData.put("txtCapacity", tvCapacity.getText().toString());
    postData.put("txtPlateNumber", tvPlateNumber.getText().toString());
    postData.put("image", toString());
    postData.put("txtFuelType", tvFuelType.getText().toString());
    postData.put("txtOwner", tvPoster.getText().toString());


    if (TextUtils.isEmpty(etResDate.getText().toString())) {
        Toast.makeText(this, "Insert reservation date.", Toast.LENGTH_SHORT).show();
        return;
    }
    postData.put("txtResDate", etResDate.getText().toString());

    if (TextUtils.isEmpty(etResTime.getText().toString())) {
        Toast.makeText(this, "Insert reservation time.", Toast.LENGTH_SHORT).show();
        return;
    }
    postData.put("txtResTime", etResTime.getText().toString());

    if (TextUtils.isEmpty(etResLocation.getText().toString())) {
        Toast.makeText(this, "Insert pickup location.", Toast.LENGTH_SHORT).show();
        return;
    }
    postData.put("txtResLocation", etResLocation.getText().toString());


    postData.put("txtRenter",  pref.getString("username","").toString());


    PostResponseAsyncTask taskPost = new PostResponseAsyncTask(DetailActivity.this, postData, new AsyncResponse() {
        @Override
        public void processFinish(String s) {
            if (s.contains("New records created successfully")) {
                Log.d(TAG, s);
                Toast.makeText(DetailActivity.this, "Wait for owners approval", Toast.LENGTH_SHORT).show();
                Intent in = new Intent(DetailActivity.this, RenterTabs.class);
                startActivity(in);
                finish();
            } else {
                Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_SHORT).show();
            }

        }
    });

    taskPost.execute("http://carkila.esy.es/rent.php");
}

// *****只需调用方法 selectImage() ****** img_user_photo //图片查看
