Remove top margin of a TextView

Question

I've got some LinearLayout objects with several things in them, including two TextViews. Unfortunately, I've got a huge space between them and I don't know why.

See by yourself (between the content frame and the #642954 - 14/25/9814 thing):

Here is my code:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    >

    <ImageView
        android:id="@+id/img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="top"
        android:contentDescription="@string/smiley"
        android:padding="10dp"
        />

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:layout_weight="1"
        android:includeFontPadding="false"
        >

        <TextView android:id="@+id/contenu"
             android:layout_width="fill_parent"
             android:layout_height="fill_parent"
             android:background="@drawable/round"
             android:padding="10dp"
             android:layout_margin="5dp"
             android:includeFontPadding="false"
             android:layout_marginBottom="-10dp"
             />


        <TextView android:id="@+id/infos"
             android:layout_width="fill_parent"
             android:layout_height="fill_parent"
             android:gravity="right"
             android:layout_margin="5dp"
             android:includeFontPadding="false"
             android:padding="0dp"
             android:layout_marginTop="-10dp"
             />

    </LinearLayout>

</LinearLayout>

Here is round.xml:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item>
        <shape android:shape="rectangle" >
            <solid android:color="#20000000" />

            <corners android:radius="13dp" />
        </shape>
    </item>
    <item android:bottom="2px">
        <shape xmlns:android="http://schemas.android.com/apk/res/android" >
            <solid android:color="#FFFFFF" />

            <corners android:radius="13dp" />

            <stroke
                android:width="1dp"
                android:color="#BBBBBB" />
        </shape>
    </item>

</layer-list>

Could you help me?

Thanks!

Answer 1

android:includeFontPadding="false"

Answer 2

No, no, no. You use negative margins, which may have unspecified behavior (presumably depending on Android OS version). I've tested this on API 8, and negative margins simply don't work. Instead, set each and every margin to a custom non-negative value, like so:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    >

    <ImageView
        android:id="@+id/img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="top"
        android:contentDescription="@string/smiley"
        android:padding="10dp"
        />

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:layout_weight="1"
        android:includeFontPadding="false"
        >

        <TextView
            android:id="@+id/contenu"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_marginBottom="0dp"
            android:layout_marginLeft="5dp"
            android:layout_marginRight="5dp"
            android:layout_marginTop="5dp"
            android:background="@drawable/round"
            android:includeFontPadding="false"
            android:padding="10dp"
            android:text="" />

        <TextView
            android:id="@+id/infos"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_marginBottom="5dp"
            android:layout_marginLeft="5dp"
            android:layout_marginRight="5dp"
            android:layout_marginTop="0dp"
            android:gravity="right"
            android:includeFontPadding="false"
            android:padding="0dp"
            android:text="" />

    </LinearLayout>

</LinearLayout>

Here, I've set all margins to 5dp except for:

• contenu's bottom margin: 0dp
• infos' top margin: 0dp

And voila, all the space is gone. Set them to your liking to adjust the gap between first and second TextView.

Edit

I've checked SDK sources for unspecified behavior I was writing above.

It turns out that when specifying margins for LinearLayout children, you have two options one of which must you choose:

1. Set margin property. This effectively sets all side margins to the value of margin. Beware: This option has precedence, meaning, if you set non-negative value for margin it will ignore any values which you have individually set for any side margins.
2. Set every side margin individually.

You were setting global margin value which effectively caused the marginTop/marginBottom values to be ignored.

Answer 3

try this for equal spacing

   <TextView android:id="@+id/contenu"
             android:layout_width="fill_parent"
             android:layout_height="fill_parent"
             android:background="@drawable/round"
             android:padding="10dp"
             android:layout_margin="5dp"
             android:includeFontPadding="false"
             android:layout_marginTop="5dp"
             />


        <TextView android:id="@+id/infos"
             android:layout_width="fill_parent"
             android:layout_height="fill_parent"
             android:gravity="right"
             android:layout_margin="5dp"
             android:includeFontPadding="false"
             android:padding="0dp"
             android:layout_marginTop="5dp"
             />
