How to align table content in Android

I want to align content of TableLayout in android. I want align the table headers too. what changes needed in main.xml?

<TableRow android:layout_margin="0dp" android:id="@+id/myRow"> 
<TextView android:id="@+id/myTitle" android:layout_span开发者_开发知识库="5" android:text="" android:layout_gravity="center_horizontal" />
</TableRow> 
<TableRow> <TextView android:layout_span="5" android:background="#000000" android:height="1dp" android:gravity="right" /> 
 </TableRow>

See the Developer pages about Common Layout Objects. You have to add gravity to your elements inside your table.

No problem since every table row has its own definition.

use the "gravity" to achieve your needs, for example

<TableRow android:id="@+id/tableRow1" android:layout_height="wrap_content" android:layout_width="fill_parent">
    <TextView android:text="TextView" android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:gravity="left"></TextView>
    <TextView android:text="TextView" android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:gravity="center_vertical|center_horizontal"></TextView>
</TableRow>

• the textbox in the first column is left-alligned
• the textbox in the second column is centered vertically and horizontally

which turns out to look like this:

have a look here for gravity details

additionally you can use padding to preserve some space left/right/above/under
