Question

我正在创建一款适用于Android的应用程序，只需点击一下，当我计算和打印并计算点数时，应用程序崩溃，我会给你错误和代码，但我找不到任何有趣的东西，所以我要求你的帮助^^

代码：

package com.example.fixe.sollsicesapp;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {



    int clicker = 1;
    int amount;
    int amount;

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

        AddListenerOnmb();

    }

    private void AddListenerOnmb() {
        Button button = (Button) findViewById(R.id.mb);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                TextView tx = (TextView) findViewById(R.id.textView2);
                amount = clicker + amount;
                tx.setText(amoun);
            }
        });






    }


}

错误：
