Android - EditText multi-line, force fill height

I need an EditText that fills the height of my window. I use this:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true" >

<EditText
    android:id="@+id/text_editor"
    android:layout_width="match_parent"
    android:layout_height="fill_parent"
    android:background="#ff0000"
    android:gravity="top|left"
    android:inputType="textMultiLine"
    android:textColor="@android:color/white" />

</ScrollView>

But all I get is one EditText line that will be longer and scroll after I write something on a multi-line set of return button. I know that I can set the line number, but in this case it should work on different devices, and each device (I think) has a different number of lines.

How can I make it fill the device in height?

Any tips?

Try using (without ScrollView):

<EditText
    android:id="@+id/text_editor"
    android:layout_width="match_parent"
    android:layout_height="fill_parent"
    android:background="#ff0000"
    android:gravity="top|left"
    android:textColor="@android:color/white" />

EditText, , .

<EditText
android:id="@+id/text_editor"
android:layout_width="match_parent"
**android:layout_height="wrap_content"**
android:background="#ff0000"
android:gravity="top|left"
android:inputType="textMultiLine"
android:textColor="@android:color/white" />

, , ,

android:lines="number of Lines"

If you can add it to the code, it will look like this:

EditText et = new EditText(this);
l.addView(et, new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, 100));

where 100means it will have 100dp width. l- this is Layoutone that you may have ( ScrollViewin your case) that you can get using R.layout.name_of_the_scroll_view.

I'm not sure, but try to set the height property WRAP_CONTENT.

RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <EditText
        android:id="@+id/editText1"
        android:scrollbars="vertical" <-----------
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:gravity="top|left"
        android:ems="10"
        android:text=" example text" />

</RelativeLayout>

in java code install this .....

ed1 = (EditText) findViewById(R.id.editText1);
ed1.setMovementMethod(new ScrollingMovementMethod()); <--------

Will work on all devices.

Hope this helps you.

My code works for me.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
android:orientation="vertical" >

<ImageView
    android:id="@+id/imageView20"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:contentDescription="@string/img_desc1"
    android:src="@drawable/num74_head_payakorn" />

<TableRow
    android:id="@+id/tableRow1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <EditText
        android:id="@+id/edtPayakorn"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:textSize="22sp"
        android:clickable="false"
        android:cursorVisible="false"
        android:editable="false"
        android:enabled="true"
        android:focusable="false"
        android:focusableInTouchMode="false"
        android:gravity="top|left"
        android:scrollbars="vertical"
        android:inputType="textMultiLine" />
    </TableRow>
</LinearLayout>
