如何将主活动中的整数传递给自定义对话框

我想将主活动中的整数数据发送到自定义对话框，此整数将帮助选择文本视图和按钮

此代码在另一个活动中调用自定义对话框

主要活动

exit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                counter=1;
                CustomDialogClass cdd=new CustomDialogClass(MainActivity.this,getApplicationContext(),counter);
                try{
                    Toast.makeText(MainActivity.this,"ExitCounter",Toast.LENGTH_LONG).show();
                }catch (Exception e){
                    Toast.makeText(MainActivity.this,e.toString(),Toast.LENGTH_SHORT).show();
                }
                //cdd.show();
            }
        });
        hello = (Button) findViewById(R.id.test_hello);
        hello.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                counter=2;
                CustomDialogClass cdd=new CustomDialogClass(MainActivity.this,getApplicationContext(),counter);
                try{
                    Toast.makeText(MainActivity.this,"HelloCounter",Toast.LENGTH_LONG).show();
                }catch (Exception e){
                    Toast.makeText(MainActivity.this,e.toString(),Toast.LENGTH_SHORT).show();
                }
               // cdd.show();
            }
        });

这是自定义对话框的代码

package com.example.mhaad.test;

import android.app.Activity;
import android.app.Dialog;
import android.content.Context;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;

import android.util.Log;
import android.view.View;
import android.view.Window;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

class CustomDialogClass extends Dialog implements android.view.View.OnClickListener {

    public Activity c;
    public Button yes, no,ok;
    public TextView hello,exit;
    public int selection;
    Context context;

    public CustomDialogClass(Activity a, Context applicationContext,int con) {
        super(a);
        // TODO Auto-generated constructor stub
        this.c = a;
        this.context=applicationContext;
        selection=con;
        Toast.makeText(context,"Con",Toast.LENGTH_LONG).show();
        show();
    }
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        Toast.makeText(context,"onCreate",Toast.LENGTH_LONG).show();
        Toast.makeText(context,""+selection,Toast.LENGTH_LONG).show();
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_custom_dialog_box);
        yes = (Button) findViewById(R.id.btn_yes);
        no = (Button) findViewById(R.id.btn_no);
        ok=(Button)findViewById(R.id.btn_ok);
        exit = (TextView) findViewById(R.id.txt_dia);
        hello = (TextView) findViewById(R.id.txt_dia1);
        exit.setVisibility(View.INVISIBLE);
        hello.setVisibility(View.INVISIBLE);
        yes.setVisibility(View.INVISIBLE);
        no.setVisibility(View.INVISIBLE);
        ok.setVisibility(View.INVISIBLE);
        yes.setOnClickListener(this);
        no.setOnClickListener(this);
        ok.setOnClickListener(this);
    }
    @Override
    public void onClick(View v) {
        Toast.makeText(context,"Click",Toast.LENGTH_LONG).show();
        switch(selection){
            case 1:
                Log.e("asd",String.valueOf(selection));
                exit.setVisibility(View.VISIBLE);
                hello.setVisibility(View.INVISIBLE);
                yes.setVisibility(View.VISIBLE);
                no.setVisibility(View.VISIBLE);
                ok.setVisibility(View.INVISIBLE);
                switch (v.getId()) {
                    case R.id.btn_yes:
                        c.finish();
                        break;
                    case R.id.btn_no:
                        dismiss();
                        break;
                    case R.id.btn_ok:
                        dismiss();
                        break;
                    default:
                        break;
                }
                break;

            case 2:
                Log.e("asd",String.valueOf(selection));
                exit.setVisibility(View.INVISIBLE);
                hello.setVisibility(View.VISIBLE);
                yes.setVisibility(View.INVISIBLE);
                no.setVisibility(View.INVISIBLE);
                ok.setVisibility(View.VISIBLE);
                switch (v.getId()) {
                    case R.id.btn_yes:
                        c.finish();
                        break;
                    case R.id.btn_no:
                        dismiss();
                        break;
                    case R.id.btn_ok:
                        dismiss();
                        break;
                    default:
                        break;
                }
                break;

            default:
                break;
        }
        dismiss();
    }
}

这是清单

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

整数传递给自定义对话框，但整数在对话框结束后传递给onClick（），我已经尝试了所有东西，但onClick（）函数不能访问int值 . 需要帮忙！！
