TextView的文本对齐方式

Question

<?xml version="1.0" encoding="utf-8"?>
<TableLayout
    android:id="@+id/widget33"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:stretchColumns="*"
    xmlns:android="http://schemas.android.com/apk/res/android">
<TableRow
    android:id="@+id/widget34"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">
<TextView
    android:id="@+id/widget35"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="TextView"
    android:gravity="center" />
<TextView
    android:id="@+id/widget36"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="TextView"
    android:gravity="center" />
<TextView
    android:id="@+id/widget37"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="TextView"
    android:gravity="center" />
</TableRow>
</TableLayout>

The text in TextViews is not aligned to the centre even though the gravity is set center .Text is shifted to extreme right.When I check the same code in droidDraw every thing seems fine.Whats happening?

Answer 1

只要您为android:layout_width和android:layout_height使用wrap_content ，重力就不会做任何事情。

Answer 2

//尝试

android:layout_gravity="center" 

Answer 3

If you set TextView to wrap_content it takes up as small space as posible. When you set it to center it centers inside the wrap_content. This makes it seem that there is no difference.

If you set TextView to fill or match_parent it will center inside the TableLayout.
