How Can I Make A Listview In Android Studio?

I'm trying to make a ListView for my Android project but unfortunately when I import these libraries: import android.app.ListActivity; import android.os.Bundle; import android.wid

Solution 1:

CustomAdapter class :-

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


publicclassCustomAdapterextendsBaseAdapter
{

    Context context;
    String[] rooms;
    publicCustomAdapter(Context c)
    {
        context = c;
        Resourcesres= c.getResources();
        rooms = res.getStringArray(R.array.images);
    }
    @OverridepublicintgetCount() {
        return rooms.length;
    }

    @Overridepublic Object getItem(int position) {
        return rooms[position];
    }

    @OverridepubliclonggetItemId(int position) {
        return position;
    }

    @Overridepublic View getView(int position, View convertView, ViewGroup parent) {

        LayoutInflaterinflater= (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        Viewview=  inflater.inflate(R.layout.single_row,parent,false);
        TextViewtxt= (TextView) view.findViewById(R.id.txt_item);
        Stringtemp= rooms[position];
        txt.setText(temp);
        return view;
    }
}

MainActivity class :-

publicclassMainActivityextendsActionBarActivity
{


    @OverrideprotectedvoidonCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ListViewlistView= (ListView) findViewById(R.id.listView);
        listView.setAdapter(newCustomAdapter(this));
     }

}

Add this to your string.xml :-

<string-arrayname="images"><item>Living Room</item><item>Master Bedroom</item><item>Children Bedroom</item><item>Kitchen1</item><item>Kitchen2</item><item>Gallery</item></string-array>

Add this to your activity_main.xml :-

<ListView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:dividerHeight="0.1dp"
    android:divider="#666666"
    android:id="@+id/listView" />

single_row.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"><TextViewandroid:layout_width="match_parent"android:layout_height="match_parent"android:textSize="20sp"android:gravity="start"android:text="Large Text"android:typeface="serif"android:id="@+id/txt_item"android:padding="3dp"android:paddingLeft="5dp"android:layout_alignParentLeft="true"android:layout_alignParentStart="true" /></RelativeLayout>
