Linear Layout Does not align baselines and Relative layout doesn't allow weights

Question

I have a Linear layout with vertical orientation in which I'm inserting several view groups. One of them is:

<LinearLayout
   android:id="@+id/addedit_updowncontrol"
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:layout_below="@+id/textView2"
   android:layout_marginBottom="5dp" 
   android:orientation="horizontal">

    <Button
        android:id="@+id/addedit_btndecrement"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_weight="0.1"
        android:text="-" />

    <EditText
        android:id="@+id/addedit_txtQuantity"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:minWidth="90dp"
        android:layout_weight="0.4"
        android:layout_alignParentTop="true"
        android:inputType="numberDecimal" />

    <Button
        android:id="@+id/addedit_btnIncrement"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_weight="0.1"
        android:layout_toLeftOf="@+id/addedit_units"
        android:text="+" />

    <Spinner
        android:id="@+id/addedit_units"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
            android:layout_weight="0.4"
        android:layout_alignParentTop="true"
    android:layout_alignParentRight="true" />

</LinearLayout>

This gives me a view that looks like this (apologies for the link, I wish there was a better way). This is unacceptable as the Button does not align with the EditText.

I tried switching to RelativeLayout, which gives me something like this. This is unacceptable as the two buttons (-) and (+) are not of the same width.

I guess what I'm trying to achieve is: (1) The baseline of the Button is aligned with the other controls in the row. (2) The two button are of the same width.

I seem to be able to achieve (1) with RelativeLayout and (2) with LinearLayout. But not both.

Can anyone help me please?

Answer 1

use

android:gravity="center_vertical"

in your linearlayout. All items will be centered

Answer 2

Change the orientation of Linear Layout to horizontal and set baselinealigned attribute to true in xml. Play with layout_weights. Assign the same weight to both buttons. Hope this helps
