如何删除TextView的上边距?

问题描述

我确实对TextView有问题.我不想在它上面有任何边距/填充.

I do have a problem with TextView. I don't want to have any margin/padding above it.

<TextView android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:id="@+id/ptp_hour"
          android:textColor="@color/black"
          android:textSize="100dp"
          android:height="100dp"
          android:layout_marginTop="0dp"
          android:paddingTop="0dp"
          android:includeFontPadding="false"
          android:maxLines="1"
          android:text="10"/>

我的TextView看起来像这样，尽管textSize和height设置为相同的值，但是字体上方还是有一个空格.这让我感到困扰，因为我想相对于字体顶部放置另一个视图.字体本身是否包含此间距?

My TextView looks like this and despite the textSize and height are set to the same value, there is a space above font. It bothers me because I want to put another view relatively to the top of the font. Is this spacing included into font itself?

另一个问题:如果我发现从顶部开始的20dp和从底部开始的7dp在我的设备上可以正常工作，我是否可以依靠它在其他屏幕上以类似的方式运行?(这些边距用于按钮)

And another question: If I found out that margin 20dp from top and 7dp from bottom works perfectly on my device, can I rely that it will behave in a similar way on other screens?(these margins are for buttons)

推荐答案

使用android:includeFontPadding="false"在类似情况下对我有很大帮助.

using android:includeFontPadding="false" helped me a lot in a similar situation.
