当用户键入时，如何防止 EditText 调整自身大小？

Question

I have an EditText and a Button set next to each other on the same horizontal line. It looks great, except when the user enters a lot of text, the EditText is resized, and the Button is squished.

I have both EditText and Button set to layout_width="wrap_content" . "fill_parent" messes up the layout, and I don't want to use absolute sizes if I don't have to - the way it is now looks great in both landscape and portrait, I just don't want the EditText to resize.

My layout:

<TableLayout
    android:id="@+id/homelayout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <TableRow>
        <TextView
            android:id="@+id/labelartist"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Find artists:" />
    </TableRow>
    <TableRow>
        <EditText
            android:id="@+id/entryartist"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="6"
            android:background="@android:drawable/editbox_background"
            android:editable="true"
            android:padding="5px"
            android:singleLine="true" />
        <Button
            android:id="@+id/okartist"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:layout_marginLeft="10dip"
            android:layout_weight="1"
            android:text="Search" />
    </TableRow>

</TableLayout>

Answer 1

For EditText use

android:layout_width="0dp" - not required but preferred.
android:layout_weight="1"

And for Button dont specify android:layout_weight

Answer 2

What I do is in the onCreate for the activity, measure the EditText first then apply its maxWidth.

You can do so using code similar to the following:

EditText someedittext = (EditText)findViewById(R.id.sometextview);
someedittext.setMaxWidth(someedittext.getWidth());

Answer 3

Give EditText a maxWidth . That should stop it from resizing beyond the width you provided. Also, if you want it to be contained within 1 line set the maxLines setting to 1 too.

Answer 4

You need to add android:imeOptions to prevent this behavior.

Answer 5

Just use:

android:layout_width="fill_parent"

for both EditText and Button. It will also work set for EditText but it is better to have it on both.

Answer 6

you can define size of your edittext as it shows above

android:minWidth="80dp"
android:maxWidth="80dp"

or

android:layout_width="60dp"

or

you can apply a background image of size you want but don't forget to define its height and width with wrap_content.

  android:layout_width="wrap_content"
  android:layout_height="wrap_content"

Answer 7

I had a similar problem, but I couldn't get the above to work. What I did, is take in the text from EditText box and then format it down to the max size that my screen could handle. When I save this off to the DB, I will save it as display Text and original text.

If you go to this page I put a longer explanation.

Answer 8

I had the exact query. But i had an EditText and a Button next to each other in a Linear Layout. I tried android:layout_weight="1" for EditText android:layout_width="0dp" And it worked just perfect!! Thanks a lot!

Answer 9

The chosen solution works, but let me add a little complement:
if you use android:layout_weight="0.15" (the value is not important)
then
android:layout_width="0dp" if the LinearLayout is Horizontal
or
android:layout_height="0dp" if the LinearLayout is Vertical.

Answer 10

The correct way to do this would be to set the android:minWidth and android:maxWidth equal to the width you want. This way you will not have to adjust your layout to use the android:layout_weight.

For example if you want your EditText to always be 80 density pixels no matter how many characters you type in use the following:

android:minWidth="80dp"
android:maxWidth="80dp"
