I cannot figure out why but I keep getting \[code\]E/AndroidRuntime(709): java.lang.NullPointerException\[/code\] at any point I try to call the buttons titled yes and no. The buttons are created in an xml layout and called using the \[code\]findViewById\[/code\] method, a similar technique I've used in several properly working buttons in the same program. The only difference between these buttons and the rest is that their xml code is kept in a separate layout file that is not the main.xml. If I only want to show the buttons and don't call them within the java code they will show up just as they should. The error occurs when I try to apply anything to them in the java code, such as \[code\]setClickable()\[/code\] and \[code\]setOnClickListener()\[/code\].The code below outlines the creation of the button and layout in the xml and the java code shows a method that creates a popup when called.Java Code:\[code\] private void getLogoutOption() { LayoutInflater layoutInflater = (LayoutInflater)getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE); View popupView = layoutInflater.inflate(R.layout.logoutoption, null); final PopupWindow logoutoption = new PopupWindow(popupView, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); Button yes = (Button) findViewById (R.id.yes); yes.setClickable(true); yes.setOnClickListener(new OnClickListener() { public void onClick(View arg0) { logoutoption.dismiss(); switchActivity(8); } }); Button no = (Button) findViewById (R.id.no); no.setClickable(true); no.setOnClickListener(new OnClickListener() { public void onClick(View arg0) { logoutoption.dismiss(); } }); logoutoption.showAsDropDown(search, 50, -30);}\[/code\]XML CODE:\[code\]<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@android:color/transparent" >" <RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/menu_default" > <TextView android:id="@+id/logoutmessage" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:text="Are you sure you would like to logout?" android:textColor="@color/gold" /> <Button android:id="@+id/yes" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/logoutmessage" android:layout_centerInParent="true" android:text="YES" android:textColor="@color/green" /> <Button android:id="@+id/no" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/logoutmessage" android:layout_toRightOf="@id/yes" android:text="NO" android:textColor="@color/red" /> </RelativeLayout></RelativeLayout>\[/code\]
