I have a table in Mysql database with some plugs, and i added all the plugs to spinner from database.I want to retreive the data according to spinner selection.I am facing a problem that there is two records in database for plug1,when i selected plug1 its retreiving properly,when i selected plug2 in spinner its retreiving another record of plug1. I have used on-selected item position that is why it is taking position wise order.

Unable to set ListView Divider color in Android

I have an activity with a ListView in it. I have set the color of ListView divider to black using android:divider="#000000" attribute and set the divider height to 1dp. For some reason the divider line is showing blue color instead of black. Here is my xml. Any help will be appreciated.
second_selection.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"

<FrameLayout

android:layout_height="25dp"
android:background="#000000" />
<include

Update:
This problem persists only in devices having API < 19

if nothing works, then u can create your own divider.
First remove the default divider.
android:dividerHeight="0dp"
android:divider="#null"
And then add the view in your custom_row_layout.xml
`
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="30dp"
android:paddingTop="8dp"
android:paddingBottom="8dp"
android:textSize="17sp"
android:textColor="#color/white" />
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#color/white" />
</LinearLayout>
`

I set up a style for ListViews, in my styles.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
...
<style name="ListViews" parent="#android:style/Widget.ListView">
<item name="android:cacheColorHint">#color/transparent</item>
<item name="android:divider">#drawable/list_divider</item>
<item name="android:dividerHeight">1px</item>
</style>
...
</resources>
My ListView uses that style as such:
style="#style/ListViews"
Obviously, I have such drawable in my drawable folder.
My list_divider.xml drawable is as such:
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"
>
<solid android:color="#color/navy_semi" />
</shape>
[EDIT]
Obviously, instead of #color/transparent and #color/navy_semi, use your own colors.
These ones are defined only in my color resurces.

Use android:background instead of android:divider
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#1A1A1A"
android:orientation="vertical"
tools:context="com.example.saregama.MainActivity" >
<FrameLayout
android:id="#+id/myframe"
android:layout_width="match_parent"
android:layout_height="25dp"
android:background="#000000" />
<include
android:id="#+id/new_tool"
layout="#layout/toolbar_actionbar_with_headerbar" />
<ImageView
android:id="#+id/loader"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="30dp"
android:src="#drawable/newloading" />
<ListView
android:id="#+id/product_list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:divider="#000000"
android:dividerHeight="1dp"
android:layoutAnimation="#anim/layout_bottom_to_top_slide"
android:padding="10dp"
android:text="#string/hello_world" />

use below attribute in your list view.
android:cacheColorHint="#null"

Now the layout file for this is list_note.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0.96"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/ViewTitleNotes"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_margin="20dp"
android:textColor="#000000"
android:textStyle="bold"
android:focusable="false"
android:focusableInTouchMode="false"
/>
</RelativeLayout>
</LinearLayout>
</LinearLayout>
When I implement above code every thing works fine. However, I want to include some other data so i am calling another layout file which includes additional data:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/mainText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Pinned Questions" />
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/mainText"
android:background="#FFFFFF"
/>
<TextView
android:id="#android:id/empty"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/mainText"
android:text="There is no data"
android:textStyle="bold" />
</RelativeLayout>
When I include this layout the list shows up but nothing happens when I click on list item. The normal working would be when I click list item it should open the next activity with desired clicked item.
Thanks in advance.

Well I would suggest You To Implement View.OnItemClickListener() and then use
noteListView.setOnItemClickListener(this);
This will work perfectly.
Hope I Helped.

please help me to solve this problem.thanking you in advance.

after getting the title as follows:
title= (TextView) findViewById(R.id.item_title);
use setText method to set the title as you wish.
I think it will solve your problem.

Seems like you forgot to call setContentView(R.layout.your_layout); in your onCreate method

That button might not be part of the ListView, just of the main layout of that Activity.
If I understand what you're saying, you have a main view containing a ListView and a Button. If that affirmation is right, then you need to use an Activity instead of ListActivity or use :
mActivity= this ;
Button button = new Button(this);
button.setText("push me");
button.setLayoutParams(new AbsListView.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(mActivity, "push", Toast.LENGTH_SHORT).show();
}
});
getListView().addFooterView(button);
Be sure to call addFooterView(View v) before setAdapter(ListAdapter adapter)

Instead of use OnClickListener, please try to use onItemClikListener.
You are in a ListActivity, so I think (maybe I'm wrong) that what you want is to make call with the selected row. So remove bCall and its onClickListener and try
getListView().setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:3492395504"));
startActivity(callIntent);
}
});

You are getting an NPE because you are trying to do this:
bCall = (Button) findViewById(R.id.bCall);
When you haven't set a layout for the screen.
That button is in your list row layout so you need to set it's function in your list adapter.

If I'm understanding your code, you are kicking off an AsyncTask in onCreate, that sets the listAdaper within its onPostExecute method. Also, in onStart you are attempting to get the button bCall.
However, if onStart executes before your background task has completed, then you will not yet have set the adapter, thus your button will not exist and your call (Button) findViewById(R.id.bCall) will return null
