Question

大家好，基本上我将2个按钮转换为1。我有一个按钮用于将图像上传到数据库，另一个按钮用于将数据上载到数据库。这是我的代码：

public static final String UPLOAD_URL = "http://animotradings.000webhostapp.com/upload.php";
public static final String UPLOAD_KEY = "image";

//Categories Spinner
Spinner spinner;
ArrayAdapter<CharSequence> adapter;

//Meet-up Spinner
Spinner spinner2;
ArrayAdapter<CharSequence> adapter2;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_sell_activityy);

    //PhotoUpload
    buttonChoose = (Button) findViewById(R.id.buttonChoose);
    buttonUpload = (Button) findViewById(R.id.buttonUpload);

    imageView = (ImageView) findViewById(R.id.imageView);

    buttonChoose.setOnClickListener(this);
    buttonUpload.setOnClickListener(this);

    // Categories Spinner
    spinner = (Spinner)findViewById(sCategories);
    adapter = ArrayAdapter.createFromResource(this, R.array.category_types, android.R.layout.simple_spinner_item);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter);
    spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            Toast.makeText(getBaseContext(), parent.getItemAtPosition(position)+" selected", Toast.LENGTH_LONG).show();
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {

        }
    });

    // Meet-up Spinner
    spinner2 = (Spinner)findViewById(smeetup);
    adapter2 = ArrayAdapter.createFromResource(this, R.array.meetup_location, android.R.layout.simple_spinner_item);
    adapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner2.setAdapter(adapter2);
    spinner2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            Toast.makeText(getBaseContext(), parent.getItemAtPosition(position)+" selected", Toast.LENGTH_LONG).show();
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {
        }
    });

    final EditText etItemName = (EditText) findViewById(R.id.etItemName);
    final EditText etCondition = (EditText) findViewById(R.id.etCondition);
    final EditText etDescription = (EditText) findViewById(R.id.etDescription);
    final EditText etPrice = (EditText) findViewById(R.id.etPrice);
    final EditText etContact = (EditText) findViewById(R.id.etContact);
    final Spinner sCategories  = (Spinner) findViewById (R.id.sCategories);
    final Spinner smeetup = (Spinner) findViewById (R.id.smeetup);
    final Button bSubmit = (Button) findViewById(R.id.bSubmit);

    bSubmit.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            final String item_name = etItemName.getText().toString();
            final String conditionn = etCondition.getText().toString();
            final String description = etDescription.getText().toString();
            final int price = Integer.parseInt(etPrice.getText().toString());
            final double contact = Double.parseDouble(etContact.getText().toString());
            final String categories = sCategories.getSelectedItem().toString();
            final String meetup = smeetup.getSelectedItem().toString();


            // Data Upload...
            Response.Listener<String> responseListener= new Response.Listener<String>(){

                @Override
                public void onResponse(String response) {
                    try {
                        JSONObject jsonResponse = new JSONObject(response);
                        boolean success = jsonResponse.getBoolean("success");

                        if (success){
                            Intent intent =  new Intent(SellActivityy.this, NavigationDrawer.class);
                            SellActivityy.this.startActivity(intent);
                        } else{
                            AlertDialog.Builder builder = new AlertDialog.Builder(SellActivityy.this);
                            builder.setMessage("Ad posting failed!")
                                    .setNegativeButton("Retry", null)
                                    .create()
                                    .show();
                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                }
            };

            SellRequest sellRequest = new SellRequest(item_name, conditionn, description, price, contact, categories, meetup, responseListener);
            RequestQueue queue = Volley.newRequestQueue(SellActivityy.this);
            queue.add(sellRequest);
        }
    });
}

//PhotoUpload

private void showFileChooser() {
    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
}

private int PICK_IMAGE_REQUEST = 1;

private Button buttonChoose;
private Button buttonUpload;
private Button buttonView;

private ImageView imageView;

private Bitmap bitmap;

private Uri filePath;
@Override

    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {

        filePath = data.getData();
        try {

private void viewImage() {

我尝试在bsubmit.onclicklistener中传输代码，并尝试更改提交和上传按钮的代码，但到目前为止还没有成功。对不起那些noob问题的人，我实际上是Android Studio的新手，并且很难适应。我将继续尝试不同的代码，也许从头开始，但如果你们能帮助我，那就太好了。谢谢：D

Answer 1

在bSubmit.onClickListener（）中，只需添加

buttonUpload.performClick();

这将模仿按钮按下上传按钮并执行它的任务。

Android Studio上传按钮和提交按钮1
