Dialog Benutzerdefinierte Box kann nicht geschlossen werden

Question

Hier ist mein Code für eine Tätigkeit ist, die einen benutzerdefinierten Dialogfeld in sich einbettet:

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(){} 
} 

Hier ist meine customxml.xml Datei

<?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> 

Problem ist Wenn ich auf die Schaltfläche im benutzerdefinierten Dialogfeld klicke, wird meine App abrupt geschlossen. Die Entlassung() wird aus irgendeinem Grund nicht aufgerufen. Bitte helfen

android:onClick="rempopup"

Answer 2

Versuchen Sie folgendes:

Herausgegeben

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(); 
    } 
}); 

Und in der .xml-Datei

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

Hope this helfen :)

Answer 3

versuchen:

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