Swipeleft to delete not working in expandable height listview

The application which i am creating has an expandable list view in which i have added the option of swipe to edit and delete.I have added those option but when i run the application it doesn't shows the swipe option even i have tried with another list view but there it works fine.
I have used the swipe option inside the base adapter can anyone tell me why the swipe functionality doesn't works in expandable list view.

Android: Hidden part of view doesn't show after drag it up

I'm trying to use ViewDragHelp to implement draggable panel but the problem is the hidden part of panel isn't shown. Picture what i meant

Encounter Range-seek-bar runtime error in android

I have used this tutorial https://code.google.com/p/range-seek-bar/#Example_usage_as_Integer_range?.
Encountered runtime error of my activity stopped. Would like to seek help from you. I attempted to correct the following compile errors as listed below.
RangeSeekBar<Integer> seekBar = new RangeSeekBar<Integer>(20, 75, context);
Context cannot be resolved to a variable
I tried adding changing context to this.
Log.i(TAG, "User selected new range values: MIN=" + minValue + ", MAX=" + maxValue);
TAG cannot be resolved to a variable.
I tried adding "protected static final String TAG = null;" to main activity.
ViewGroup layout = (ViewGroup) findViewById(<your-layout-id>)
Does the layout id refer to my main_activity.xml in my layout?
Really grateful for your feedback.

Edited Code to allow TextView to display range.

seekBar.setOnRangeSeekBarChangeListener(new OnRangeSeekBarChangeListener<Integer>() {
#Override
public void onRangeSeekBarValuesChanged(RangeSeekBar<?> bar, Integer minValue, Integer maxValue) {
// handle changed range values
String powerranger = "User selected new range values: MIN=" + minValue + ", MAX=" + maxValue;
Log.i(TAG, powerranger);
textview.setText(powerranger);
}
});
// add RangeSeekBar to pre-defined layout
LayoutInflater inflater = (LayoutInflater)getApplicationContext().getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
ViewGroup layout = (ViewGroup) inflater.inflate(R.layout.activity_main,null);
layout.addView(seekBar);
setContentView(layout);
}

RangeSeekBar seekBar = new RangeSeekBar(20, 75, context); 1. Context cannot be resolved to a variable
this must work:
RangeSeekBar seekBar = new RangeSeekBar(20, 75, this);
Log.i(TAG, "User selected new range values: MIN=" + minValue + ", MAX=" + maxValue); 2. TAG cannot be resolved to a variable. I tried adding "protected static final String TAG = null;" to main activity.
Don't set it to null. Usually you use the app or component name, e.g.
protected static final String TAG = "MyApp";
ViewGroup layout = (ViewGroup) findViewById() 3. Does the layout id refer to my main_activity.xml in my layout?
Use this:
LayoutInflater inflater = (LayoutInflater)getApplicationContext().getSystemService (Context.LAYOUT_INFLATER_SERVICE);
ViewGroup layout = (ViewGroup) inflater.inflate(R.layout.activity_main,null);
layout.addView(seekBar);
setContentView(layout);

Try to implement custom RangeSeekBar.

how to add fast scroll and alphabetical section index in listview

In details, I am looking for an example exactly like below image. I got a good example in this link https://github.com/woozzu/IndexableListView.

if i add this it works code in mainactivity
listView = (ListView) findViewById(R.id.homelistView);

your are using a custom ListView class, com.woozzu.android.widget.IndexableListView
You have to replace your "ListView " in layout file to a "com.woozzu.android.widget.IndexableListView"
Change your Layout to:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:background="#ff3344"

android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#ffffff"
android:layout_alignTop="#+id/scrollView1"
android:layout_toRightOf="#+id/scrollView1" >
<com.woozzu.android.widget.IndexableListView
android:id="#+id/homelistView"
android:layout_width="0dip"
android:layout_height="fill_parent"
android:layout_weight="1.04"
