Layout_Width of a Listview

Layout_width of a ListView

By setting the width to "wrap_content" you are telling ListView to be as wide as the widest of its children. ListView must therefore measure its items and to get the items it has to call getView() on the Adapter. This may happen several times depending on the number of layout passes, the behavior of the parent layout, etc.

Remember there are no guarantees on the number of times getView() is invoked on the Adapter, nor in what orders the calls will happen. You must therefore implement getView() to be as efficient as possible. The bottom line is, this is not an issue, it's the expected behavior in this situation.

Android LinearLayout weight and wrap_content of ListView

As it is said in here and in here, standart android ListView can not have wrap_content as a width since the width of child elements may be different.

As a workaround, one should use RecycleView instead of ListView.

Android Layout - layouts of 3 textviews inside a listview

Try Using Relative Layout with your code.

Replace this with your XML Code.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

    <TextView
        android:id="@+id/text1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_marginLeft="5dp"
        android:text="Test" />

    <TextView
        android:id="@+id/text2"
        android:layout_width="80sp"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_marginLeft="25dp"
        android:layout_toLeftOf="@+id/text3"
        android:layout_toRightOf="@+id/text1"
        android:maxEms="15"
        android:singleLine="false"
        android:text="TEsting TEsting TEsting TEstingTEstingTEstingTEstingTEsting " />

    <TextView
        android:id="@+id/text3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_marginLeft="25dp"
        android:layout_marginRight="5dp"
        android:text="Test"
        android:textSize="30dp" />
</RelativeLayout>

Here is Screen Shot How it Looks with Above XML.

android layout dynamic width of listviews

Don't EVER put ListView inside ScrollView, anyways here is how you do it:

<LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent">

        <ListView
                android:layout_width="0dp"
                android:layout_height="fill_parent" android:layout_weight="20"
                android:id="@+id/listView2" />

        <ListView
                android:layout_width="0dp"
                android:layout_height="fill_parent" android:layout_weight="20"
                android:id="@+id/listView3" />

        <ListView
                android:layout_width="0dp"
                android:layout_height="fill_parent" android:layout_weight="20"
                android:id="@+id/listView4" />

        <ListView
                android:layout_width="0dp"
                android:layout_height="fill_parent" android:layout_weight="20"
                android:id="@+id/listView5" />

        <ListView
                android:layout_width="0dp"
                android:layout_height="fill_parent" android:layout_weight="20"
                android:id="@+id/listView6" />

    </LinearLayout>

ListView takes up all space in LinearLayout

That is because you are using fill_parent, and it will do exactly that.

You could try something along the lines of this... It will cause the ListView to expand to fill the space.

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

    <ListView
        android:id="@+id/list_view"
        android:layout_width="match_parent"
        android:layout_weight="1"
        android:layout_height="0dp"/>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="10dp">

        <EditText
            android:layout_width="match_parent"
            android:layout_height="40dp"
            android:hint="Hej"/>
    </LinearLayout>
</LinearLayout>

Another alternative is to use a RelativeLayout. So long as the height of the ListView is not wrap_content, it should be OK.

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

    <ListView
        android:id="@+id/list_view"
        android:layout_width="match_parent"
        android:layout_above="@+id/footer"
        android:layout_height="match_parent"/>

    <LinearLayout
        android:id="@+id/footer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:padding="10dp">

        <EditText
            android:layout_width="match_parent"
            android:layout_height="40dp"
            android:hint="Hej"/>
    </LinearLayout>
</RelativeLayout>

How to use android:layout_weight with listview

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="0dp"
    android:layout_weight="25"
    android:orientation="horizontal" >

    <Button

        android:text="Button1" />
</LinearLayout>
