ListActivity Full Screen Method

Question

I have created a list of 7 days and want the list to take the full screen. But the list is having a gap in the bottom. I want to remove the gap.

My code is as follows :

package com.example.collegehack;

import android.app.ListActivity;

import android.content.Intent;
import android.database.DataSetObserver;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Adapter;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class Days extends ListActivity {

    String days[] = { "Monday", "Tuesday", "Wednesday", "Thursday", "Friday",
            "Saturday", "Sunday" };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setListAdapter(new ArrayAdapter<String>(Days.this,
                android.R.layout.simple_list_item_1,days));
    }

    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        // TODO Auto-generated method stub
        super.onListItemClick(l, v, position, id);
        String temporary = days[position];
        try {
            Class ourClass = Class.forName("com.example.collegehack"
                    + temporary);

            Intent ourIntent = new Intent(Days.this, ourClass);
            startActivity(ourIntent);
        } catch (ClassNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

Please help me with this problem. Thanks in advance.

Answer 1

To do so you need to inflate your own view.

Follow these steps:

1. Create my_layout.xml contained textView:

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

<TextView 
    android:id="@+id/textView1"
    android:gravity="center_vertical"
    android:layout_centerVertical="true"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

</RelativeLayout>

2. In your adapter, you need to override the getView() method and set the rows height like this:

setListAdapter(new ArrayAdapter<String>(MainActivity.this,
            android.R.layout.simple_list_item_1,days) {
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            if(convertView == null) {
                convertView = getLayoutInflater().inflate(R.layout.my_layout, parent, false);
                convertView.getLayoutParams().height = parent.getHeight() / getCount();
                convertView.requestLayout();
                TextView tv = (TextView) convertView.findViewById(R.id.textView1);
                tv.setText(getItem(position));
            }
            return convertView;
        }
    });

3. Disable the list scrolling because the dividers height doesn't count in this workaround and your listView will scroll by a millimeter:

getListView().setOnTouchListener(new OnTouchListener() {

        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() == MotionEvent.ACTION_MOVE) {
                return true; // Indicates that this has been handled by you
                                // and will not be forwarded further.
            }
            return false;
        }
    });

That's it! Have fun :)
