Answer 1

you need to use android:weightSum properly, giving android:layout_height="0dp" if you have android:orientation="vertical"

check below xml code,

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

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:weightSum="2">

        <android.support.v7.widget.CardView
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_marginLeft="5dp"
            android:layout_marginRight="5dp"
            android:layout_marginTop="5dp"
            android:layout_weight="1"
            android:elevation="10dp"
            card_view:cardCornerRadius="5dp">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_margin="10dp"
                android:orientation="vertical"
                android:weightSum="10">

                <ImageView
                    android:id="@+id/img1"
                    android:layout_width="match_parent"
                    android:layout_height="0dp"
                    android:layout_gravity="center"
                    android:layout_weight="7"
                    android:scaleType="fitXY"
                    android:src="@mipmap/ic_true"/>

                <TextView
                    android:id="@+id/tv_name1"
                    android:layout_width="wrap_content"
                    android:layout_height="0dp"
                    android:layout_marginBottom="5dp"
                    android:layout_marginTop="5dp"
                    android:layout_weight="1"
                    android:gravity="center"
                    android:text="test"
                    android:textSize="18sp"
                    android:textStyle="bold"/>

                <TextView
                    android:id="@+id/tv_version1"
                    android:layout_width="wrap_content"
                    android:layout_height="0dp"
                    android:layout_weight="1"
                    android:gravity="center"
                    android:text="test"/>

                <TextView
                    android:id="@+id/tv_api_level1"
                    android:layout_width="wrap_content"
                    android:layout_height="0dp"
                    android:layout_weight="1"
                    android:gravity="center"
                    android:text="test"/>
            </LinearLayout>
        </android.support.v7.widget.CardView>

        <View
