XML : XML organization problems - android

I'm having an issue how to organize the XML file to be as the following picture. I have spent enough time, I couldn't do it. If you could assist me what configuration I should do. There is no restriction on how to organize. but if it is possible to teach me new method instead of parent-child.

My XML is:

  <?xml version="1.0" encoding="utf-8"?>  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"      xmlns:tools="http://schemas.android.com/tools"      android:layout_width="match_parent"      android:layout_height="match_parent"      android:orientation="horizontal"      tools:context="com.ahmed.bluetooth.DataAnalysis">          <TextView          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:text="Peak Pressures"          android:layout_weight="1"/>      <TextView          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:text="Time in Sec."          android:layout_weight="1"/>          <LinearLayout      android:layout_width="wrap_content"      android:layout_height="wrap_content"      android:orientation="horizontal"      android:layout_weight="1">      <TextView          android:id="@+id/text_Index"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_weight="1"          android:text="@string/Peaks_index"          android:textColor="#040307"          android:scrollbars="vertical"/>      <TextView          android:id="@+id/Peak_Num"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_weight="1"          android:text="Peaks"          android:textColor="#040307"          android:scrollbars="vertical"/>      <Button          android:id="@+id/button_Del"          android:layout_width="wrap_content"          android:layout_height="wrap_content"          android:layout_weight="1"          android:text="Delete File"          android:background="@drawable/button"          android:layout_margin="1dp" />  </LinearLayout>    </LinearLayout>
