XML/Java - Creating Two OnClick Methods and RadioButton Writing to Specific Values

This is a Noob question. I am sorry if it has been answered. I have been searching but either could not find or understand the answer. Anyway, I am trying to write a simple weight and balance program for a fleet of aircraft but I'm not sure how to proceed.
I'm trying to figure out how to have the program write to a specific field while a certain radio button is checked.
Could anyone be of any assistance? Thank you!

Android ListView onScroll Fires Multiple Times

I have two views in my fragment. In the first view, I have a linear layout, which holds some controls and in the second view, I have a listview.
I want the linear layout in the first view to be collapsed / expand when I scroll up / down listview.
I tried to handle scroll up / down events of listview in the OnScrollListener and collapse / expand the listview.
But there is a problem with the onScroll method,i.e, when I scroll the listview, it fires many times when I scroll the listview one time. So expanding and collapsing process of linear layout is going crazy.
Here is - what is happening on the screen.

What am I doing wrong?
What is the best way to handle scrol up / down events of listview and collapse / expand linear layout?

expand(mTransactionsFilterLinearLayout);
} else {

collapse(mTransactionsFilterLinearLayout);
}
mInitialScroll = scrolledOffset;
}
}
});

I think the solution is not possible with the classic ListView of Android SDK.
I found a custom ListView called Android-ObservableScrollView and implemented it in my project and the result is success.
You can find it from here
https://github.com/ksoichiro/Android-ObservableScrollView/

try setting a booolean value like this as global.
boolean flag = true;
then
if (scrollUp) {
if(flag == false){
Log.d("Scroll", "Up");
expand(mTransactionsFilterLinearLayout);
}
flag = true;
} else {
if(flag == true){
Log.d("Scroll", "Down");
collapse(mTransactionsFilterLinearLayout);
}
flag = false;
}

Show/Hide top bar like chrome, but with some static content and a listview

First let me give a short introduction and then show you what end goal looks:
So far I've added a scrolllistener to my listactivity, so that I can detect scrolling, though it does not give me any animation on android:animateLayoutChanges="true". So when i change the margin's of the view programmatically, it just does these changes instantly, and not that well, any help is most welcomed.
As you can see in my xml, i place the item I'm going to hide slowly first so other will be above it on the Z-axis.

How to add a view to the bottom of android drawer

While designing the UI for an android app I faced the following problem. I wanted to align the item in the ListView of the drawer to the bottom. I am new to android development. Any help will be appreciated.
This is my drawer code
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#E0E0E0" >
<!-- Your main screen -->
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/tvLocation"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginTop="10dp"
android:text="Location: "
android:textAppearance="?android:attr/textAppearanceSmall" />
<TextView
android:id="#+id/tvLocInfo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="Rajeev Chowk, Block A, Connaught Place"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textStyle="bold" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/tvTime"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginTop="10dp"
android:text="Time: "
android:textAppearance="?android:attr/textAppearanceSmall" />
<TextView
android:id="#+id/tvTimeInfo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="9:30 PM"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textStyle="bold" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.79"
android:orientation="vertical" >
<ImageView
android:id="#+id/ivMap"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_marginTop="10dp"
android:layout_weight="0.85"
android:scaleType="fitXY"
android:src="#drawable/map" />
<Button
android:id="#+id/btnPanic"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.1"
android:background="#drawable/red_button"
android:text="Panic Button"
android:textColor="#FFFFFF" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_marginTop="10dp"
android:layout_weight="0.010"
android:background="#drawable/top_border" >
</LinearLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="5dp" >
<TextView
android:id="#+id/tvDeviceStatus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:text="Device Status: Working"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textStyle="bold" />
<TextView
android:id="#+id/tvDeviceStatus1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/tvDeviceStatus"
android:layout_marginLeft="20dp"
android:layout_marginTop="10dp"
android:text="Battery: 91%(~11 months)"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textStyle="bold" />
</RelativeLayout>
</LinearLayout>
<!-- left drawer -->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
<ListView
android:id="#+id/left_drawer"
android:layout_width="380dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#E0E0E0"
android:choiceMode="singleChoice"
android:dividerHeight="1dp" />
</android.support.v4.widget.DrawerLayout>
These are the three xml file that I inflate in the ListView
1) profile_view.xml
<ImageView
android:id="#+id/ivProfile"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingRight="10dp"
android:src="#drawable/sneha_lata" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:orientation="vertical" >
<TextView
android:id="#+id/tvName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Sneha Lata"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textStyle="bold" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:orientation="horizontal" >
<TextView
android:id="#+id/tvEdit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Edit Profile"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textStyle="" />
<ImageView
android:id="#+id/ivForward"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/forward" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
2) emergency_view.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="20dp"
android:paddingTop="20dp" >
<TextView
android:id="#+id/tvManage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="40dp"
android:text="Manage Emergency Contacts"
android:textAppearance="?android:attr/textAppearanceMedium" />
<ImageView
android:id="#+id/ivForward"
android:layout_toRightOf="#id/tvManage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/forward" />
<TextView
android:id="#+id/tvManageText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/tvManage"
android:layout_alignParentLeft="true"
android:layout_alignRight="#id/tvManage"
android:layout_marginLeft="40dp"
android:fontFamily="sans-serif-light"
android:text="#string/tvManageText"
android:textAppearance="?android:attr/textAppearanceSmall" />
</RelativeLayout>
3) logout view
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/logout_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<Button
android:id="#+id/btnLogout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#drawable/red_button"
android:text="Log Out"
android:textColor="#FFFFFF" />
</RelativeLayout>
Even if I used android:layout_alignParentBottom="true" in my logout_view.xml still it does not align at the bottom in the drawer but it does in logout_view.xml
This is the code for the DrawerAdapter
package com.majhe.android.adapter;
import com.majhe.android.LoginActivity;
import com.majhe.android.R;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.view.ViewGroup.LayoutParams;
import android.webkit.WebView.FindListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.RelativeLayout;
public class DrawerAdapter extends ArrayAdapter<String> implements OnClickListener {
Context context;
Button btnLogout;
public DrawerAdapter(Context context) {
super(context, android.R.layout.simple_list_item_1, new String[] {
"Profile View", "Emergency View", "Logout View" });
this.context = context;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = ((Activity) context).getLayoutInflater();
switch (position) {
case 0:
convertView = inflater.inflate(R.layout.profile_view, null, true);
return convertView;
case 1:
convertView = inflater.inflate(R.layout.emergency_view, null,true);
return convertView;
case 2:
convertView = inflater.inflate(R.layout.logout_view, null, true);
btnLogout=(Button)convertView.findViewById(R.id.btnLogout);
btnLogout.setOnClickListener(this);
return convertView;
}
return super.getView(position, convertView, parent);
}
#Override
public void onClick(View v) {
context.startActivity(new Intent(context,LoginActivity.class));
((Activity)context).finish();
}
}

I think you dont need to use ListView at all if I am right? replace your listview with something like this might help
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#fff"
android:orientation="vertical"
android:paddingEnd="10dp" android:gravity="bottom">
<include layout="#layout/profile_view"/>
<include layout="#layout/emergency_view"/>
<include layout="#layout/logout_view"/>
</LinearLayout>
set layout_height 0 dp and layout_weight to 1 of the view to fill the remaining space ( most probably emergency_view ) so that your logot_view will alwyas stick to bottom

this is what the logcat shows

use
Context mContext = v.getApplicationContext();
instead of
Context mContext = getApplicationContext();
or
builder = new AlertDialog.Builder(StartMoving.this);
EDIT :
You are reading button
todo = (Button) findViewById(R.id.bgoto); <-----------
^^^^^
todo.setOnClickListener(this);

AlertDialog.Builder diag = new AlertDialog.Builder(this);
diag.setTitle("DIALOG TITLE")
.setMessage("YOUR MESSAGE")
.setCancelable(false)
.setNegativeButton("WHAT EVER THE BUTTON TEXT",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//enter code here
//do what ever the button in the dialog is clicked
dialog.cancel();
}
});
diag.show();
Easiest way to have a alert dialog
and dont forget to change the Button id in java to R.id.goto

if your are using alertDialog in TabHost then you have to write..
final AlertDialog alertDialog = new AlertDialog.Builder(**getParent()**).create();
//alertDialog.setTitle("Alert....");
alertDialog.setMessage("Your Text");
alertDialog.setButton("OK", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface arg0, int arg1)
{
finish();
}
});
alertDialog.show();

It seems that I've been reading the button from the Context and not from the alertDialog. The solution was to create a View that will be set as View for the AlertDialog and declare a button and set it as a child for the View.
final View view;
LayoutInflater inf = LayoutInflater.from(StartMoving.this);
view = inf.inflate(R.layout.rename, null);
final EditText newname = (EditText) view.findViewById(R.id.etNewRoomName);
final Button todo = (BUtton) view.findViewById(R.id.bTodo);
new AlertDialog.Builder(StartMoving.this)
.setView(view)
.setTitle("Rename")
.setMessage("Enter new name for room " + currentRoom)
.show();
