Unwanted padding in layout

Question

I'm new in the android programmation world and I'm facing some layout design problems. There is a padding in the layout containing the two images, see the red arrow:

As you can see I'm using the wrap_content attribute for both heigh and width, so I don't really understand why this is happening...

Here is my layout:

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context="com.scimoon.henri.scimoon.Game"
    android:background="@color/white"
    android:orientation="vertical">

    <LinearLayout
        android:orientation="horizontal"
        android:paddingTop="15dp"
        android:paddingBottom="5dp"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@color/darkBlue"
        android:id="@+id/back">
        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:src="@drawable/back"/>
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10dp"
            android:text="@string/back"
            android:textColor="@color/white"
            android:textSize="35dp"/>
    </LinearLayout>


    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:layout_gravity="center_horizontal"
        android:layout_weight="1">
        <ImageView
            android:id="@+id/bt_bleu"
            android:scaleType="fitXY"
            android:adjustViewBounds="true"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:src="@drawable/bt_bleu"
            android:layout_weight="1"/>
        <ImageView
            android:id="@+id/bt_rouge"
            android:scaleType="fitXY"
            android:adjustViewBounds="true"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/bt_rouge"
            android:layout_weight="1"/>
    </LinearLayout>


    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:layout_gravity="center_horizontal"
        android:layout_weight="1">

        <ImageView
            android:id="@+id/bt_jaune"
            android:scaleType="fitXY"
            android:adjustViewBounds="true"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:src="@drawable/bt_jaune"
            android:layout_weight="1"/>

        <ImageView
            android:id="@+id/bt_vert"
            android:scaleType="fitXY"
            android:adjustViewBounds="true"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/bt_vert"
            android:layout_margin="0dp"
            android:padding="0dp"
            android:layout_weight="1"/>

    </LinearLayout>
</LinearLayout>

Any idea how to get rid of this ?

Answer 1

在您的res文件夹中，有一个名为values的文件夹，其中应存在一个名为dimens.xml的文件，打开该文件，您会发现边距设置为1dp或0dp

Answer 2

在两个包含圆圈的LinearLayouts上删除android:layout_weight="1" 。
