ButtonClikListner事件未在Custom_dialogue中触发| Android

Question

在我的一个活动Surah.java中，我使用了custom_dialogue和custom_dialog.xml来提示用户。该对话框包含两个按钮。我只想处理这两个按钮的click events。我已经写过custom_dialog.java的处理程序，但这没有什么区别。

custom_dialog.xml

<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/text" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:text="" 
    android:textAppearance="?android:attr/textAppearanceMedium" 
    android:textColor="#FFFFFF" /> 

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:gravity="center" 
    android:orientation="horizontal" > 

    <Button android:id="@+id/ok" 
    android:layout_width="90dp" 
    android:layout_height="40dp" 
    android:layout_alignParentBottom="true" 
    android:text="OK" /> 
<Button android:id="@+id/cancel" 
    android:layout_width="90dp" 
    android:layout_height="40dp" 
    android:layout_alignParentBottom="true" 
    android:text="Cancel" /> 
</LinearLayout> 

    </LinearLayout> 

custom_dialog.java

package com.quran.peacequran; 

import android.app.Activity; 

import android.os.Bundle; 
import android.view.View; 
import android.widget.Button; 
import android.widget.Toast; 

public class custom_dialog extends Activity { 


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


     Button button= (Button) findViewById(R.id.cancel); 
      button.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        Toast.makeText(getApplicationContext(), "No stores", 5000).show(); 
       } 
      }); 

    } 

}

public class Surah extends Fragment { 

.... 
public void onActivityCreated(Bundle savedInstanceState) { 
    super.onActivityCreated(savedInstanceState); 

    MyAdapter adapter = new MyAdapter(getActivity(), generateData()); 

    // 2. Get ListView from activity_main.xml 
    ListView listView = (ListView) getView().findViewById(R.id.listView1); 



    listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() { 
     public boolean onItemLongClick(AdapterView<?> arg0, View v,int index, long arg3) { 
         Toast.makeText(getActivity(),"thul thuk!",Toast.LENGTH_SHORT).show(); 
        Dialog dialog = new Dialog(getActivity()); 
        dialog.setContentView(R.layout.custom_dialog); 
        dialog.setTitle("BookMark Surah?"); 
        dialog.show(); 
       return false; 
        } 
     }); 
    } 
... 
} 

Answer 1

use the below code to get the onclick in Surah.java inside the listView.setOnItemLongClickListener(....... after you create the dialog object 


dialog.findViewById(R.id.ok).setOnClickListener(new OnClickListener() { 

         @Override 
         public void onClick(View v) { 
          // TODO Auto-generated method stub 
          Toast.makeText(getApplicationContext(), "it works", 2000).show(); 
         } 
        });
