ListView into ScrollView in Android

Hello Friends!

Today I am going to share very important code for ListView into ScrollView.

Many Android developers says: “You should not put a ListView in a ScrollView because a ListView already a scrollview.

 But some times its really needed in project “ how can place a ListView into a ScrollView without it collapsing to its minimum height?”

And finally I got it on stack over flow-

I waste a lot of time in goggling so I don’t want some one do same so you can follow my blog step by step-

PrintScren:

Step1- Create an Activity name-MainActivity.java and create a listview.

package com.example.scrollviewlistviewdemo;

import android.os.Bundle;

import android.app.Activity;

import android.widget.ArrayAdapter;

import android.widget.ListView;

public class MainActivity extends Activity {

       private String listview_array[] = { "ONE", "TWO", "THREE", "FOUR", "FIVE",

                     "SIX", "SEVEN", "EIGHT", "NINE", "TEN" };

       ListView myList;

       @Override

       protected void onCreate(Bundle savedInstanceState) {

              super.onCreate(savedInstanceState);

              setContentView(R.layout.activity_main);

              myList = (ListView) findViewById(R.id.listView);

              myList.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, listview_array));

              Helper.getListViewSize(myList);

      

       }

}

Step2- Create main.xml-

<ScrollView 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"

    tools:context=".MainActivity" >

    <LinearLayout

        android:layout_width="match_parent"

        android:layout_height="match_parent"

        android:orientation="vertical" >

        <TextView

            android:layout_width="wrap_content"

            android:layout_height="wrap_content"

            android:layout_marginTop="19dp"

            android:text="@string/hello_world" />

        <ImageView

            android:layout_width="50dp"

            android:layout_height="50dp"

            android:src="@drawable/ic_launcher" />

        <ListView

            android:id="@+id/listView"

            android:layout_width="fill_parent"

            android:layout_height="fill_parent" />

    </LinearLayout>

</ScrollView>

Step3- Finally and important thing create another class Helper.java and put below given code-

package com.example.scrollviewlistviewdemo;

import android.util.Log;

import android.view.View;

import android.view.ViewGroup;

import android.widget.ListAdapter;

import android.widget.ListView;

public class Helper {

    public static void getListViewSize(ListView myListView) {

        ListAdapter myListAdapter = myListView.getAdapter();

        if (myListAdapter == null) {

            //do nothing return null

            return;

        }

        //set listAdapter in loop for getting final size

        int totalHeight = 0;

        for (int size = 0; size < myListAdapter.getCount(); size++) {

            View listItem = myListAdapter.getView(size, null, myListView);

            listItem.measure(0, 0);

            totalHeight += listItem.getMeasuredHeight();

        }

      //setting listview item in adapter

        ViewGroup.LayoutParams params = myListView.getLayoutParams();

        params.height = totalHeight + (myListView.getDividerHeight() * (myListAdapter.getCount() - 1));

        myListView.setLayoutParams(params);

        // print height of adapter on log

        Log.i("height of listItem:", String.valueOf(totalHeight));

    }

}

Hope it will help you thanks!
