自定义对话框无法关闭

以下是我自己编写自定义对话框的活动代码：

package com.example.hotel_app_regularuser;

import android.animation.ObjectAnimator;
import android.app.ActionBar.LayoutParams;
import android.app.Activity;
import android.app.Dialog;
import android.content.Intent;
import android.graphics.Color;
import android.graphics.Typeface;
import android.os.Bundle;
import android.util.TypedValue;
import android.view.Menu;
import android.view.View;
import android.view.animation.AlphaAnimation;
import android.view.animation.Animation;
import android.view.animation.LinearInterpolator;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.PopupWindow;
import android.widget.TextView;
import android.widget.Toast;

public class GetUserPreference extends Activity implements Runnable {
    TextView tv,tr;
    Button bt;
    Thread t1;
    Dialog d;
    ObjectAnimator textColorAnim;
    LinearLayout lyt,lyt2; 
    PopupWindow popUp;
    LayoutParams params;
    Button cbutton;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_get_user_preference);
        tv=(TextView)findViewById(R.id.textView1);
        lyt= (LinearLayout) findViewById(R.id.LinearLayout1);
        lyt2=new LinearLayout(this);
        popUp = new PopupWindow(this);
        t1=new Thread(this);
        cbutton=(Button)findViewById(R.id.closebutton);
        Typeface type = Typeface.createFromAsset(getAssets(),"fonts/rs.ttf"); 
        Intent it=getIntent();
        String a=it.getStringExtra("username");
        tv.setText("Welcome"+"   "+a);
        tv.setTypeface(type);
        tv.setTextSize(TypedValue.COMPLEX_UNIT_SP,50);
        tv.setTextColor(Color.RED);
        d = new Dialog(this);
        bt=(Button)findViewById(R.id.button1);
        final Animation animation = new AlphaAnimation(1, 0); // Change alpha from fully visible to invisible
        animation.setDuration(500); // duration - half a second
        animation.setInterpolator(new LinearInterpolator()); // do not alter animation rate
        animation.setRepeatCount(Animation.INFINITE); // Repeat animation infinitely
        animation.setRepeatMode(Animation.REVERSE); // Reverse animation at the end so the button will fade back in
        // bt.startAnimation(animation);
        bt.startAnimation(animation);
        d.setContentView(R.layout.customxml);
        d.setTitle("welcome");
        TextView t = (TextView)d.findViewById(R.id.textView1);
        t.setText("hiii");
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.get_user_preference, menu);
        return true;
    }


    public void go(View vw)
    {
        d.show();   
    }

    public void rempopup(View v)
    {
        d.dismiss();
    }

    @Override
    public void run(){}
}

这是我的customxml.xml文件 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView" />

    <Button
        android:id="@+id/closebutton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button"
        android:onClick="rempopup"/>

</LinearLayout>

问题是，当我点击自定义对话框中的按钮时，我的应用程序突然关闭。由于某种原因，不会调用dismiss（）。请帮忙

这是我的崩溃日志

试试这个：

<强>被修改 

final Dialog d = new Dialog(this);
Button Button = (Button) d.findViewById(R.id.closebutton);

Button.setOnClickListener(new OnClickListener() {
   @Override
   public void onClick(View v) {
   d.dismiss();
  }
});

在您的.xml文件中

<Button
    android:id="@+id/closebutton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Button"/>

希望这会有所帮助：）

        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            // Inflate the menu; this adds items to the action bar if it is present.
            getMenuInflater().inflate(R.menu.get_user_preference, menu);

        }


        public void go(View vw) {
            d.show();
        }

//        public void rempopup(View v) {
//            d.dismiss();
//        }

        @Override
        public void run() {
        }
    }

也删除

android:onClick="rempopup"

试试这个：

public void rempopup(View v)
    {
     if(v.getId() == R.id.closebutton)
               d.dismiss();
    }
