Question

I have the following xml layout:

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#FF99E6"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10dip"
            android:layout_marginTop="5dip"
            android:text="Was patient"
            android:textAppearance="?android:attr/textAppearanceLarge" />

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="2dip"
            android:background="#298EB5"
            android:orientation="horizontal" >
        </LinearLayout>

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="7dip"
            android:layout_marginTop="10dip"
            android:text="Hier wat extra info"
            android:textAppearance="?android:attr/textAppearanceMedium" />

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="0dip"
            android:layout_gravity="center"
            android:layout_weight="1"
            android:background="#FF6633"
            android:orientation="vertical" >

            <TimePicker
                android:id="@+id/timePicker1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center" />
        </LinearLayout>

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"

            android:background="#298EE5"
            android:orientation="horizontal" >

            <Button
                android:id="@+id/button1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Button" />

            <Button
                android:id="@+id/button2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Button" />
        </LinearLayout>
    </LinearLayout>
</ScrollView>

This produces the following output:

Now I want to center that datepicker in the orange container. I setted the attribute to center, but that only centers it horizontal.

I can only use linearlayout, so please no suggestions to use relative layout 🙂

I’ve been struggeling with this for a while, so any help would be greatly appreciated!

Thx

Answer 1

Remove android:layout_gravity on both your timepicker and orange container and set android:gravity="center" to your orange container to make it center.

android:gravity define the gravity of childs, while layout_gravity define the gravity of the layout/view itself.
