Android: Sizing Image Buttons and TextViews?

I am trying to add 3 text views and ImageButtons to my android layout. I have been trying to size them so that all 6 components fit on screen.

I trust that this is a very simple issue but I cannot solve it, it is very fustrating.

How can I do so?

Layout code:

<?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="match_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/tvFirstTabMaths"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Maths"
        android:textSize="15dp" />

    <ImageButton
        android:id="@+id/ibFirstTabMathsButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/mathsicon" />

    <TextView
        android:id="@+id/tvFirstTabMemory"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text=" Memory"
        android:textSize="15dp" />


    <ImageButton
        android:id="@+id/ibFirstTabMemoryButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/memoryicon" />


     <TextView
        android:id="@+id/tvFirstTabStroop"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Stroop"
        android:textSize="15dp" />

    <ImageButton
        android:id="@+id/ibFirstTabStroopButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/stroopicon" />


</LinearLayout>

Try doing this:

 <?xml version="1.0" encoding="utf-8"?>

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="match_parent">
    <LinearLayout android:layout_width="match_parent"
        android:layout_height="match_parent" android:orientation="vertical">

        <TextView android:id="@+id/tvFirstTabMaths"
            android:layout_width="match_parent" android:layout_height="wrap_content"
            android:text="Maths" android:textSize="15dp" android:layout_weight="1" />

        <ImageButton android:id="@+id/ibFirstTabMathsButton"
            android:layout_width="match_parent" android:layout_height="wrap_content"
            android:src="@drawable/mathsicon" android:layout_weight=".5" />

        <TextView android:id="@+id/tvFirstTabMemory"
            android:layout_width="match_parent" android:layout_height="wrap_content"
            android:text=" Memory" android:textSize="15dp" android:layout_weight="1" />


        <ImageButton android:id="@+id/ibFirstTabMemoryButton"
            android:layout_width="match_parent" android:layout_height="wrap_content"
            android:src="@drawable/memoryicon" android:layout_weight=".5" />


        <TextView android:id="@+id/tvFirstTabStroop"
            android:layout_width="match_parent" android:layout_height="wrap_content"
            android:text="Stroop" android:textSize="15dp" android:layout_weight="1" />

        <ImageButton android:id="@+id/ibFirstTabStroopButton"
            android:layout_width="match_parent" android:layout_height="wrap_content"
            android:src="@drawable/stroopicon" android:layout_weight=".5" />


    </LinearLayout>
</ScrollView>

If you want all 6 views to fit horizontally you should try getting the screen size programatically and then set the views width/params.

view.setWidth(width/6);

Is you are using linear layout you should set the android:layout_weight to the childrens. From Documentation: " This attribute assigns an "importance" value to a view in terms of how much space is should occupy on the screen. A larger weight value allows it to expand to fill any remaining space in the parent view. Child views can specify a weight value, and then any remaining space in the view group is assigned to children in the proportion of their declared weight"

If you want to make them to fill the screen, you need to use layout_weight attribute.

Change all android:layout_height="wrap_content" to android:layout_height="0dp" and add android:layout_weight="1".

The weight make the views share the space available.

The weight can be a float, and it can be anything you want. It's like ratio, if you have something at 1 and another at 2, the second will be twice as big as the first.

You can also use weight_sum="10" on the LinearLayout, then if you give your child view less that 10 in weight, there will be empty space left. For instance you would get 6/10th of the screen with your buttons and 4/10th empty.

You can also put views without weight in a container with views that has weight. The first view will take its space, and the remaining space will be shared with the rest.
