问题
I have the following layout, it works fine and gives me the result. The result I want is to divide the screen into two parts and place buttons half in each part:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="200dp" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1" >
<RelativeLayout
android:id="@+id/relative_layout_top"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ImageView
android:id="@+id/imageView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginTop="10dp"
android:scaleType="centerCrop" />
</RelativeLayout>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1" >
<RelativeLayout
android:id="@+id/relative_layout_bottom"
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="#fdd372" >
<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_marginLeft="20dp"
android:layout_marginTop="0dp"
android:text="Jason D'Silva"
android:textColor="#696969"
android:textSize="22sp" />
<TextView
android:id="@+id/textView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/textView2"
android:layout_below="@+id/textView2"
android:layout_marginTop="05dp"
android:paddingBottom="05dp"
android:paddingTop="05dp"
android:text="Me and Christine"
android:textColor="#696969" />
<!--
<TextView
android:id="@+id/placeholder"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/textView4"
android:layout_marginTop="02dp" />
-->
<TextView
android:id="@+id/textView4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="@+id/textView3"
android:layout_alignBottom="@+id/textView3"
android:layout_alignParentRight="true"
android:layout_marginRight="14dp"
android:text="24 October 2014"
android:textColor="#696969" />
</RelativeLayout>
</LinearLayout>
</LinearLayout>
<Button
android:id="@+id/imageButton1"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="10dp"
android:background="@drawable/icon_edit"
android:textColor="#000000" />
<Button
android:id="@+id/imageButton2"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_alignTop="@+id/imageButton1"
android:layout_marginRight="10dp"
android:layout_toLeftOf="@+id/imageButton1"
android:background="@drawable/icon_person" />
</RelativeLayout>
The only problem I have is that I want the android:id="@+id/relative_layout_top to take 1.5 times the space of android:id="@+id/relative_layout_bottom and still keep the buttons half in android:id="@+id/relative_layout_bottom and half in android:id="@+id/relative_layout_bottom. Currently both the halves are of the same size. Any ideas hints or suggestions how to do that?
Here is the graphical representation:

Your have to set gravity center to you both LinearLayout which place child at center and set weight 2 to top LinearLayout and 1 to bottom LinearLayout and put button in two LinearLayout used FrameLayout.
