android:textalignment 参数解释,Text/Layout Alignment in Android (textAlignment, gravity)

问题

What's the difference between android:textAlignment and android:gravity?

回答1:

All I can see is that the textAlignment is a member of the View Class and the gravity is the member of TextView class. So for the TextView and its subclasses you can use the gravity while you can use the textAlignment for all Views.

As the TextView and its subclasses need some more text-aligning features, so you can see there are more options in gravity where in textAlignment there are only basic options. Although it is only my guess because I have not found any clear documentation about the difference.

You can see these two links of documentation: textAlignment and gravity.

With API 15, android:textAlignment may not have the desired result. The snippet below attempts to centre the first TextView object using android:textAlignment="center". The second uses android:gravity="center_h
