android - Layout pushing views down the screen -

so, have imageview inside framelayout. need way. feel issue here image , it's size itself. layout image pushes further down other views on screen leaving considerable empty space that's supposed layout.

i found hard coding height value let's me minimize issue. if height wrap_content image reach same point blank space supposed layout extends extreme lengths.

so want know if image size (or resolution?) problem (which seems be) or else, , if there better solution hardcoding layout height. in advance.

here code:

<linearlayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:orientation="vertical">      <framelayout         android:layout_width="match_parent"         android:layout_height="700dp">          <imageview             android:id="@+id/image_header"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:scaletype="fitstart"             android:src="@drawable/me_and_gundam" />          <view             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:background="@drawable/gradient" />     </framelayout>       <textview         android:fitssystemwindows="true"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_marginbottom="16dp"         android:text="my nanodegree apps!"         android:textalignment="center"         android:textsize="24sp" /> 

and here looks like:

have tried putting frame layout height wrap_content worked me fine

    <imageview         android:id="@+id/image_header"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:scaletype="fitstart"         android:src="@drawable/me_and_gundam" />      <view         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:background="@drawable/gradient" /> </framelayout>
