Question

enter image description here The two button in the following code, were set to wrap_content and no padding. However, there is still some padding in the vertical orientation. If I set the android:layout_height to a fixed parameter, the padding could disappear. But I do want to use wrap_content instead of a fixed height.

EDIT: Now, I have to use DIP, which is not recommended, as text size to ensure the text in the button while using a fixed height in DIP. Looking forward to a better solution!

与布顿相比,这一内容的高度正在上升。

            <Button 
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:background="@drawable/record_selector"
                android:gravity="center"
                android:textColor="#ffffffff"
                android:text="@string/charge_record"/>

因此,实际上,各州现在并没有停下来,但是由于你根基的线索,它占用了更多的空间。

在你根基线中添加一个特性:android:gravity=“center_vertical”。

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="5dp"
    android:orientation="horizontal" 
    android:gravity="center_vertical"
    android:background="#756846">

删除这一行文:

android:layout_weight="1.0"

将0dp值改为总结

页: 1

You have 2 potential sources of the padding: first one is initial button backgroud sizes - it will not be scaled down, only up

Second one is the default style for button - just set padding = 0dp
