推荐答案
有没有这样的东西作为一个负面的保证金。
使用安卓重力=顶
如果你的TextView的比你TEXTSIZE高,您希望文本显示在顶部。否则,使用安卓layout_height =WRAP_CONTENT
。您的观点将完全适合这种方式。
There is no such thing as a negative margin.
Use android:gravity="top"
if your textview is higher than your textsize and you want the text to appear on the top. Otherwise use android:layout_height="wrap_content"
. Your view will exactly fit this way.
如果您希望TextView的顶部边框和实际文本之间3DP空间,
使用的android:paddingTop =3DP
。一般来说,保证金认为外面的自由空间,填充的边框和内容之间的内部间距。
If you want 3dp space between the top border of the textview and the actual text,
use android:paddingTop="3dp"
. Generally, margin is the free space outside the view, padding is the inside spacing between the border and the content.
