Linearlayout overlay another linearlayout

I have some problem with add linearlayout dynamically. It's add on the top of screen, overlay other linearlayout.

Here XML,code and results.

XML: 

<TextView
    android:id="@+id/top_km"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:background="#888"
    android:gravity="top"
    android:textColor="#fff"
    android:textSize="30dip"
    android:layout_centerHorizontal="true"/>

<RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_below="@+id/top_km"
        android:id="@id/textLayout">

</RelativeLayout>

Code:

myLayout = (RelativeLayout) page.findViewById(R.id.textLayout);
LinearLayout linLayout = new LinearLayout(this);  
linLayout.setOrientation(LinearLayout.VERTICAL);
LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
myLayout.addView(linLayout);
LinearLayout hozLayout = new LinearLayout(this);
hozLayout.setOrientation(LinearLayout.HORIZONTAL);
LayoutParams params = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
myLayout.addView(hozLayout);

Results: enter link description here

Don't use a RelativeLayout as your holder. Use a LinearLayout with orientation="vertical" instead.

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_below="@+id/top_km"
    android:orientation="vertical"
    android:id="@id/textLayout" />

then in code

myLayout = (LinearLayout) page.findViewById(R.id.textLayout);

followed by

// rest of your code

Maybe it's easier for you to add it in the XML file with android:visibility="GONE" and then in the code just show it (View.VISIBLE) or hide it (View.GONE).

It's because you use RealativeLayout for proper adding use 1. RelativeLayout.LayoutParams for st LayoutParams 2. In LayoutParams use field below

Example:

RelativeLayout rl=new RelativeLayout(this);
LinearLayout ll1=new LinearLayout(this);
TextView tx1=new TextView(this);
tx1.setText("Test1");
ll1.addView(tx1);
rl.addView(ll1);
LinearLayout ll2=new LinearLayout(this);
TextView tx2=new TextView(this);
tx2.setText("Test1");
ll2.addView(tx1);
rl.addView(ll2);
RelativeLayout.LayoutParams lp2=(LayoutParams) ll2.getLayoutParams();

And then use lp2.addRule

Here some help:

Parameters verb One of the verbs defined by RelativeLayout, such as ALIGN_WITH_PARENT_LEFT. anchor The id of another view to use as an anchor, or a boolean value(represented as TRUE) for true or 0 for false). For verbs that don't refer to another sibling (for example, ALIGN_WITH_PARENT_BOTTOM) just use -1.
