                valueTV.setId(0);
                valueTV.setLayoutParams(new LayoutParams(
                        LayoutParams.WRAP_CONTENT,
                        LayoutParams.WRAP_CONTENT));

Answer 1

It'll be better if you declare the TextView in the xml it self and hide and show it from the code. So there's no need of initializing the same object in each drawing.

Hiding and showing can be done with the below code

textView.setVisibility(View.VISIBLE); //TO Show
textView.setVisibility(View.INVISIBLE); //TO Hide
textView.setVisibility(View.GONE); //To Hide and Release the space to otherview.

Answer 2

In your activity get the root linearlayout by id, ie lnr_list_event. Then use method addView on the root view with index.

LinearLayout root = (LinearLayout) findViewById(R.id.lnr_list_event);

root.addView(yourHeaderView, 0, layoutparams);

Answer 3

Try This,

LinearLayout header = (LinearLayout)findViewById(R.id.header);

TextView valueTV = new TextView(Schedule.this);
            valueTV.setText("Event in Progress");
            valueTV.setTextColor(Color.parseColor("#FFFFFF"));
            valueTV.setTypeface(TypeFaceConstant.getOpensasItalic(getApplicationContext()));
            valueTV.setId(0);
            valueTV.setLayoutParams(new LayoutParams(
                    LayoutParams.WRAP_CONTENT,
                    LayoutParams.WRAP_CONTENT));
            valueTV.setGravity(Gravity.TOP);
            valueTV.setPadding(20, 0, 0, 0);
            header.addView(valueTV);

And xml file,

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/lnr_list_event"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#FFFFFF"
    android:orientation="vertical" android:paddingTop="5dp"
    android:paddingBottom="5dp" >

<LinearLayout
    android:id="@+id/header"
    android:layout_width="wrap_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >
</LinearLayout>

<LinearLayout
    android:id="@+id/lnr_list_progress"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:orientation="horizontal"
    android:paddingBottom="10dp"
    android:paddingRight="10dp"
    android:paddingTop="10dp" >

<ImageView

    android:src="@drawable/addevent" />

<LinearLayout
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginLeft="5dp"
    android:layout_weight="4"
    android:orientation="vertical" >

    <TextView

        android:layout_marginTop="1dp"
        android:text="dfdf"
        android:textColor="#000000"
        android:textSize="18sp" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center_vertical"
        android:orientation="horizontal" >

        <TextView

            android:paddingRight="10dp"
            android:singleLine="false"
            android:textColor="@color/event_titles"
            android:textSize="16sp" />

        <TextView
            android:id="@+id/event_location"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="@color/event_titles"
            android:textSize="16sp" />
    </LinearLayout>

    <TextView
        android:id="@+id/event_locationss"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="@color/event_titles"
        android:textSize="16sp"
        android:visibility="gone" />
</LinearLayout>

<ImageView

    android:layout_height="wrap_content"
