Android Imagebutton Resolution Problems

I want to have two buttons at the top of my program taking users to different activities. I'm having a lot of trouble with the formatting. How can I make it so that the buttons wil

Solution 1:

Change android:background to android:src that will keep the aspect ratio. Use android:scaleType="centerInside" to fit whole image inside button area and optionally use android:adjustViewBounds=true to remove empty spaces. Example:

<ImageButton
    android:id="@+id/incidentsSelect"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:contentDescription="Incidents"
    android:onClick="chooseIncident"
    android:src="@drawable/incident_bar2"
    android:scaleType="centerInside"
    android:adjustViewBounds="true"/>

<ImageButton
    android:id="@+id/operationalPeriodsSelect"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:contentDescription="Operational Periods"
    android:onClick="chooseOperationalPeriod"
    android:src="@drawable/operationalperiod_bar2"
    android:scaleType="centerInside"
    android:adjustViewBounds="true"/>

Solution 2:

I am guessing that you are trying to size the buttons evenly on the top of the screen. If that's the case then you should set android:layout_width="0dp".

Solution 3:

Just use android:layout_width = "wrap_content"
