我正在创建一个android移动应用程序，用户可以在其中上传自己的简历(PDF表单或字词表单)，然后将其发送到服务器.

I am creating an android mobile application in which user can upload his CV (PDF form or word form) and which can be then sent to the server.

我已经使用此代码来附加/上传PDF或Word文件，但是当我在Android Studio中运行该应用程序时，无法单击附件按钮.我该怎么解决?

I have used this code to attach/upload PDF or word file, but when I run the application in Android Studio, the attachment button can't be clicked. How can I solve it?

public class RegisterActivity extends AppCompatActivity {
    ImageButton btnAttach;

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

        getSupportActionBar().setTitle("Registeration");

        btnAttach = (ImageButton) findViewById(R.id.attachImageButton);

        // view products click event
        btnAttach.setOnClickListener(new View.OnClickListener() {

            @Override
