Android how to fit listview in Dialog

Question

I have problems to fit my ListView in a Popup Dialog when the ListView contains more than 12 ListItems. Is there any attribute I'm missing here or do I have to calculate the max size by myself in code behind?

My Layout looks like this when everything fit perfectly:

And when I have too many Items, as you can see my LinearLayout below the listview and Button disappear.

Here is my Layout.xml

<?xml version="1.0" encoding="utf-8"?>

There is no guarantee that everything will fit perfectly on all screen sizes so you what you can do is add alignParentBottom="true" to the linearLayout housing the button. However, this is a very terrible design, I would recommend using ConstraintLayout with a RecyclerView, that way you will have about 75% less code in your layout file — Rafsanjani, Oct 31 '19 at 14:27
check this [link](https://stackoverflow.com/questions/5487552) — Ehsan msz, Oct 31 '19 at 14:28
there is no attribute "alignParentBottom". I will try ContraintLayout thanks. — BR75, Oct 31 '19 at 14:35
Hey how about using a constraint layout? are you okay to use constraint layout? — Manikanta, Oct 31 '19 at 14:55
Are you sure you're actually using a ListView or RecyclerView? You seem to be using hardcoded `LinearLayout`s which are duplicated *13* times (as what @Rafsanjani has mentioned). — Edric, Oct 31 '19 at 15:41

You can do this in two ways:

FIRST:

Put everything, or exactly what you want, into a "ScrollView" and your items will be scrolled no matter how many items you place.

Ex.:

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

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

       <!-- PUT EVERYTHING YOU WANT HERE -->

    </ScrollView>
</RelativeLayout>

SECOND:

Put all your items into ListView using an adapter and an item for the list:

item_list.xml (in res > layout > New > XML > Layout XML File):

<?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="wrap_content">

    <TextView
        android:layout_margin="20dp"
        android:id="@+id/item_text"
        android:text="Test"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

</LinearLayout>

your list adapter (in java > yourPackageName > new > Kotlin File/Class):

import android.content.Context
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import android.widget.BaseAdapter
import android.widget.TextView

class ListAdapter (private val context: Context, private val listItems: ArrayList<String>) : BaseAdapter() {

    override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View {
        val view = LayoutInflater.from(context).inflate(R.layout.item_list, null)

        val text = view.findViewById<TextView>(R.id.item_text)
        text.text = listItems[position]

        return view
    }

    //It doesn't matter right now
    override fun getItem(position: Int): Any {
        return ""
    }

    //It doesn't matter right now
    override fun getItemId(position: Int): Long {
        return 0
    }

    override fun getCount(): Int {
        return listItems.size
    }
}

your activity_main.xml (where the ListView is:)

<?xml version="1.0" encoding="utf-8"?>

    android:layout_width="match_parent"

        </RelativeLayout>

    </LinearLayout>
</RelativeLayout>

MainActivity (where you call the adapter for the ListView):


import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import kotlinx.android.synthetic.main.activity_main.*

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val itemsList = ArrayList(
            arrayListOf(
                "test", "test", "test", "test", "test", "test", "test", "test", "test", "test",
                "test", "test", "test", "test", "test", "test", "test", "test", "test", "test",
                "test", "test", "test", "test", "test", "test", "test", "test", "test", "test"
            )
        )

        myListView.adapter = ListAdapter(this, itemsList)

    }
}
