How to set Textview , Edittext and button height's to be same on Linearlayout

Question

How can I set the LinearLayout items' heights to be the same? I tried with RelativeLayout but didn't have any success. Any idea how I can do it?

<LinearLayout
    android:background="@color/red"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="5dp"
    android:weightSum="11">

    <TextView
        android:id="@+id/lblParca"

        android:layout_width="0dip"
        android:layout_height="wrap_content"
        android:layout_weight="5.5"
        android:text="Parça Kodu"
        android:textSize="15dp" />

    <EditText
        android:id="@+id/txthldMalzemeKodu"
        style="@style/DefaultEditTextSmall"
        android:layout_width="0dip"
        android:layout_weight="4.5"
        android:layout_height="wrap_content"
        android:inputType="textCapCharacters"
        android:singleLine="true" />

    <ImageButton
        android:id="@+id/btnhldgetMalzeme"
        style="@style/btnStyleBreakerBay"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:src="@mipmap/ic_ara" />
</LinearLayout>

That's what I got:

If you are happy with Aspicas answer, the layout can be simplified to just

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="5dp"
    android:background="@color/red"
    android:orientation="horizontal">

    <TextView
        android:id="@+id/lblParca"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_gravity="center_vertical"
        android:layout_weight="0.40"
        android:text="Parça Kodu" />

    <EditText
        android:id="@+id/txthldMalzemeKodu"
        style="@style/DefaultEditTextSmall"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="0.40"
        android:inputType="textCapCharacters"
        android:singleLine="true"/>

    <ImageButton
        android:id="@+id/btnhldgetMalzeme"
        style="@style/btnStyleBreakerBay"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="0.20"
        android:scaleType="centerInside"
        android:src="@mipmap/ic_ara"/>
</LinearLayout>

There is no need to have all of the wrappers. Also notice the change to your TextView utilizing gravity instead of layout_gravity to center your content. I am actually surprised this works, from my understanding this should be stretching the height of the views, apparently I was wrong in that thinking.

Answer 2

One way is to hardcode the Parent's LinearLayout Height .

Other way is to take 3 Linear Layout for each of the items & in each LinearLayout
set

  android:layout_gravity="center_vertical"

Answer 3

Try with this xml file

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="5dp"
    android:background="@color/red"
    android:orientation="horizontal"
    android:weightSum="11">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal">

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_gravity="center_vertical"
            android:layout_weight="0.40"
            android:orientation="horizontal">

            <TextView
                android:id="@+id/lblParca"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:text="Parça Kodu"
                />
        </LinearLayout>

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="0.40"
            android:orientation="horizontal">

            <EditText
                android:id="@+id/txthldMalzemeKodu"
                style="@style/DefaultEditTextSmall"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:inputType="textCapCharacters"
                android:singleLine="true"/>
        </LinearLayout>

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="0.20"
            android:orientation="horizontal">

            <ImageButton
                android:id="@+id/btnhldgetMalzeme"
                style="@style/btnStyleBreakerBay"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:src="@mipmap/ic_ara"/>
        </LinearLayout>
    </LinearLayout>
</LinearLayout>

Answer 4

You can try to use android:layout_weight="1" for all views, and set android:layout_height="0"

Link on documentation.

Answer 5

you need to set up the same height for all the views. Either you do this:

android:layout_height="match_parent"

or

 android:layout_height="some value"
