删除LinearLayout中按钮之间的空间

Question

I have 8 buttons inside a LinearLayout and I don't want any space betwen them. I have tried set all padding and margins to 0 and nothing.

Any solutions?

Answer 1

You could use negative margins but could be bad practice . Most 9-patch PNGs have transparent areas around the visible ones, that could be why it looks like you have margins. Try turning-on Show layout boundaries to investigate. It's under Settings > Developer Options .

Answer 2

Try this code. Use layout_weight=1 while, layout_width="0dp" .

<LinearLayout
    android:layout_height="wrap_content"
    android:layout_width="fill_parent"
    android:padding="3dp"
    android:background="@color/green">

    <Button
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:background="@color/green"
        android:text="Submit"
        android:textColor="@color/white"
        android:layout_weight="1"
        android:id="@+id/submitQuestionnaireButton"/>
    <Button
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:background="@color/white"
        android:text="Cancel"
        android:textColor="@color/green"
        android:layout_weight="1"
        android:id="@+id/cancelQuestionnaireButton"/>
</LinearLayout>
