When I give match_parent to both width and height to inner linear layout, it does not look good, and when I tried to give left and right padding to inner linear layout the design becomes bad.I want to design this layout without giving the hard coded width.Please help

Try this :

 <LinearLayout android:layout_below="@+id/txt_buy_info"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="horizontal"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <LinearLayout
        android:layout_width="0dp"
        android:layout_weight="0.4"
        android:layout_height="wrap_content"/>

    <LinearLayout
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <android.support.v7.widget.AppCompatEditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="Rate"
            android:layout_marginTop="20dp"
            android:textColor="@color/colorBlack"
            android:textColorHint="@color/colorBlack"
            android:gravity="center"/>

        <android.support.v7.widget.AppCompatEditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="Amount"
            android:layout_marginTop="20dp"
            android:textColor="@color/colorBlack"
            android:textColorHint="@color/colorBlack"
            android:gravity="center"/>

        <android.support.v7.widget.AppCompatEditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="Quantity"
            android:layout_marginTop="20dp"
            android:textColor="@color/colorBlack"
            android:textColorHint="@color/colorBlack"
            android:gravity="center"/>

        <android.support.v7.widget.AppCompatButton
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="#ff61fffd"
            android:hint="Rate"
            android:layout_marginTop="20dp"
            android:textColor="@color/colorBlack"
            android:textColorHint="@color/colorBlack"
            android:gravity="center"/>

    </LinearLayout>

    <LinearLayout
        android:layout_width="0dp"
        android:layout_weight="0.4"
        android:layout_height="wrap_content"/>

    </LinearLayout>
