Android Designing Layout programmatically

Here is the answer but not the direct answer. This is what I personally do to create complex layout programatically.

Create the same layout in XML.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:src="@drawable/some_big_image" />

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:background="#DD000000" >

    <ImageView
        android:id="@+id/imageView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_centerVertical="true"
        android:src="@drawable/ic_launcher" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignTop="@+id/imageView2"
        android:layout_toRightOf="@+id/imageView2"
        android:text="TextView"
        android:textColor="@android:color/white" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/imageView2"
        android:layout_toRightOf="@+id/imageView2"
        android:text="TextView"
        android:textColor="@android:color/white" />
</RelativeLayout>

Now start from top parent to child.

    RelativeLayout mParent = new RelativeLayout(this);
    RelativeLayout.LayoutParams mParentParams = new RelativeLayout.LayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT));
    mParent.setLayoutParams(mParentParams);

    ImageView mBigImageView = new ImageView(this);
    mBigImageView.setLayoutParams(mParentParams);
    mParent.addView(mBigImageView);

As you practice you can directly code the same without creating xml.
