here is onClickDelete method
public void onClickDelete(View v)
{
ListView lvItems = getListView();
//get the row the clicked button is in
LinearLayout vwParentRow = (LinearLayout)v.getParent();
TextView child = (TextView) vwParentRow.getChildAt(0);
child.setText("Delete Clicked");
}
When i press delete, it shows invocationtargetexception at (TextView child = (TextView) vwParentRow.getChildAt(0);)
Sorry if this is very basic mistake. I am new to android.
Thank you for your reply.

It's better
TextView child = (TextView)findViewById("yourtextfieldIDHere");
child.setText("Delete Clicked");

LinearLayout is null inside button's onClick

I'm trying to hide a linearlayout on a button click and display another linearlayout which is in the same layout file. But the linearlayouts are null inside the onclick of the button.
The displayLayout and editLayout are null.
displayLayout = (LinearLayout) findViewById(R.id.linearLayout);
editLayout = (LinearLayout) findViewById(R.id.editLayout);
edit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
displayLayout = (LinearLayout) findViewById(R.id.linearLayout);
editLayout = (LinearLayout) findViewById(R.id.editLayout);
displayLayout.setVisibility(View.GONE); //error occurs here
editLayout.setVisibility(View.VISIBLE);
}
});

Just fix your view ID in your code
displayLayout = (LinearLayout) findViewById(R.id.displayLayout);
editLayout = (LinearLayout) findViewById(R.id.editLayout);
edit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
displayLayout.setVisibility(View.GONE);
editLayout.setVisibility(View.VISIBLE);
}
});
}

error code displayLayout = (LinearLayout) findViewById(R.id.linearLayout);
right code displayLayout = (LinearLayout) findViewById(R.id.displayLayout);
you set a not exist id.

Have you considered adding a headerview to listview. You could actually use a layout as header for listview. This way, you views on header will never overflow on to listview.
final ListView lstVRHDetails = (ListView) getActivity().findViewById(R.id.listview);
LayoutInflater inflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View headerView = inflater.inflate(<header layout>, new LinearLayout(getActivity()), false);
headerView.findViewById(R.id.rlFromDate).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
}
});
headerView.findViewById(R.id.rlToDate).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
}
});
headerView.findViewById(R.id.imgUpdate).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
}
});
headerView.setLayoutParams(new ListView.LayoutParams(ListView.LayoutParams.MATCH_PARENT, ListView.LayoutParams.WRAP_CONTENT));
lstVRHDetails.addHeaderView(headerView);

Set View.GONE for View is not right way to remove row from ListView. to remove row remove select row item from Adapter data-source and call notify data change method of adapter to populate changes:
close.setTag(position);
close.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int deletePos=Integer.parseInt(v.getTag().toString());
bpData.remove(deletePos);
notifyDataSetChanged();
}
});

Set visibility View.GONE of SCROLL VIEW or other parent of list view....

I guess the problem is with your layout Listview xml you are using relative layout they will obviously overlap each other until or unless you place them relative to each other.
You have to take out your lv_song_list from indexer_layout
You can refer

How to populate the same view with layout inflater?

I have a layout and every time my button is pressed I want to add a group of views stored in another layout. This is the way I tried it so far. The error in logcat is:
"E/AndroidRuntime(7900): java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first."
Code:
material_cost.xml
<?xml version="1.0" encoding="utf-8"?>
<ScrollView 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="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/materialCostText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Κόστος Υλικών"
android:textColor="#FF0000"
android:textSize="16sp"
android:textStyle="bold"
android:gravity="center_horizontal"
android:layout_margin="5dp"/>
<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:layout_marginBottom="8dp"
android:layout_marginTop="4dp"
android:background="#33B5E5" />
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/materialWrapper">
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp">
<Button
android:id="#+id/btnMaterialSubmit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Αποθήκευση"
android:layout_weight="50"/>
<Button
android:id="#+id/btnMaterialAdd"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Προσθήκη πεδίου"
android:layout_weight="50"/>
</LinearLayout>
</LinearLayout>
</ScrollView>
material_cost_item.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/materialItem"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:layout_width="50dp"
android:layout_height="wrap_content"
android:id="#+id/materialText"
android:text="Υλικό"
android:textSize="16sp"
android:textStyle="italic"
android:layout_weight="50"
android:layout_marginLeft="5dp"/>
<EditText
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="50"
/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:layout_width="50dp"
android:layout_height="wrap_content"
android:id="#+id/materialText"
android:text="Τιμή μονάδας"
android:textSize="16sp"
android:textStyle="italic"
android:layout_weight="50"
android:layout_marginLeft="5dp"/>
<EditText
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="50"
/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:layout_width="50dp"
android:layout_height="wrap_content"
android:id="#+id/materialText"
android:text="Ποσότητα"
android:textSize="16sp"
android:textStyle="italic"
android:layout_weight="50"
android:layout_marginLeft="5dp"/>
<EditText
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="50"
/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:layout_marginBottom="8dp"
android:layout_marginTop="4dp"
android:background="#33B5D8" />
</LinearLayout>
</LinearLayout>
And finally my class:
public class MaterialActivity extends Activity implements OnClickListener {
Button btnAdd;
LinearLayout rootLayout;
View layoutItem;
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.material_cost);
btnAdd = (Button) findViewById(R.id.btnMaterialAdd);
rootLayout = (LinearLayout) findViewById(R.id.materialWrapper);
layoutItem = getLayoutInflater().inflate(R.layout.material_cost_item, rootLayout,false);
rootLayout.addView(layoutItem);
btnAdd.setOnClickListener(this);
}
public void onClick(View v){
switch (v.getId()){
case R.id.btnMaterialAdd:{
inflateEntry();
break;
}
}
}
private void inflateEntry() {
// TODO Auto-generated method stub
Log.v("debug","pressed");
rootLayout.addView(layoutItem);
}
}

you need to inflate the view again every time you click the button:
private void inflateEntry()
{
// TODO Auto-generated method stub
Log.v("debug","pressed");
View layoutItem = getLayoutInflater().inflate(R.layout.material_cost_item, null);
rootLayout.addView(layoutItem);
}

It's better TextView child = (TextView)findViewById("yourtextfieldIDHere"); child.setText("Delete Clicked");
