Rows don't render properly in Android Layout. Buttons seem to be the problem_问答_开发者

I am new to Android Development and I am having trouble with my XML Layout... when I inly have rows with text and edittext the layout stays ok, but once I put the row with the buttons the lower rows just disappear below the screen and the rows render way apart from each other... what am I doing wrong?

The iPhone version of my app shows the layout I am trying to achieve...

Are you sure that you added the drawables @calbuttonbluesquare and clearbuttonbluesquare to your list? Also, they should be in a supported format? Try just putting each button on it's own view as a test, to make sure it's showing up right first.

I think you either need to

Set your TableLayout's layout_height and layout_width to fill_parent, or
Wrap the TableLayout inside a ScrollView.

I might be wrong since I'm not very familiar with TableLayouts, but these would be my guesses.

I am usure of what made my XML file work properly... however, the use of DIP as mesure instead of pixels was what seemed to make the difference... The modified code for inspection is posted here. I was going to attach an screenshot of the final product, I have no screenshot of the not-working version, but my reputation is not high enough to do it.

Code:

        <TableRow android:layout_height="fill_parent" android:layout_width="wrap_content" android:id="@+id/fatRow" >
            <TextView android:layout_column="0" android:layout_weight="1" android:layout_height="wrap_content" android:id="@+id/textView1" android:layout_width="wrap_content" android:text="fat" android:layout_gravity="center_vertical|right" android:gravity="right" android:layout_marginRight="5dip" android:textColor="#FFFFFF"></TextView>
            <EditText android:layout_column="1" android:layout_weight="1" android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_marginLeft="5dip" android:hint="fat" android:gravity="right" android:id="@+id/fatEditText" android:inputType="numberDecimal"></EditText>
        </TableRow>

        <TableRow android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/carboRow">
            <TextView android:layout_column="0" android:layout_weight="1" android:layout_height="wrap_content" android:id="@+id/textView3" android:layout_width="wrap_content" android:text="carbo" android:layout_gravity="center_vertical|right" android:gravity="right" android:layout_marginRight="5dip" android:textColor="#FFFFFF"></TextView>
