Question

I have created a listview using following tutorial link http://www.ezzylearning.com/tutorial.aspx?tid=1763429

Outcome of this is, List of Activity as below image

Now, I want to navigate to different activity screen by clicking on individual row. I do have idea of navigating to next screen, However I’m not able to find the correct position of each row. I don’t have much knowledge of android so please bare with my question if it is too silly.

although the code is available on the above link I’m attaching the .xml files and .java. here as well.

main.xml

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

     <ListView
        android:id="@+id/listView1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" />

</LinearLayout>

listview_item_row.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:padding="10dp">

     <ImageView android:id="@+id/imgIcon"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:gravity="center_vertical"
        android:layout_alignParentTop="true"
        android:layout_alignParentBottom="true"
        android:layout_marginRight="15dp"
        android:layout_marginTop="5dp"
        android:layout_marginBottom="5dp" />

     <TextView android:id="@+id/txtTitle"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:gravity="center_vertical"
        android:layout_alignParentTop="true"
        android:layout_alignParentBottom="true"
        android:textStyle="bold"
        android:textSize="22dp"
        android:textColor="#000000"
        android:layout_marginTop="5dp"
        android:layout_marginBottom="5dp" />

</LinearLayout>

Weather.java

public class Weather {
    public int icon;
    public String title;
    public Weather(){
        super();
    }

    public Weather(int icon, String title) {
        super();
        this.icon = icon;
        this.title = title;
    }
}

WeatherAdapter.java

public class WeatherAdapter extends ArrayAdapter<Weather>{

    Context context; 
    int layoutResourceId;    
    Weather data[] = null;

    public WeatherAdapter(Context context, int layoutResourceId, Weather[] data) {
        super(context, layoutResourceId, data);
        this.layoutResourceId = layoutResourceId;
        this.context = context;
        this.data = data;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View row = convertView;
        WeatherHolder holder = null;

        if(row == null)
        {
            LayoutInflater inflater = ((Activity)context).getLayoutInflater();
            row = inflater.inflate(layoutResourceId, parent, false);

            holder = new WeatherHolder();
            holder.imgIcon = (ImageView)row.findViewById(R.id.imgIcon);
            holder.txtTitle = (TextView)row.findViewById(R.id.txtTitle);

            row.setTag(holder);
        }
        else
        {
            holder = (WeatherHolder)row.getTag();
        }

        Weather weather = data[position];
        holder.txtTitle.setText(weather.title);
        holder.imgIcon.setImageResource(weather.icon);

        return row;
    }

    static class WeatherHolder
    {
        ImageView imgIcon;
        TextView txtTitle;
    }
}

MainActivity.java

public class MainActivity extends Activity {

    private ListView listView1;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Weather weather_data[] = new Weather[]
        {
            new Weather(R.drawable.weather_cloudy, "Cloudy"),
            new Weather(R.drawable.weather_showers, "Showers"),
            new Weather(R.drawable.weather_snow, "Snow"),
            new Weather(R.drawable.weather_storm, "Storm"),
            new Weather(R.drawable.weather_sunny, "Sunny")
        };

        WeatherAdapter adapter = new WeatherAdapter(this, 
                R.layout.listview_item_row, weather_data);


        listView1 = (ListView)findViewById(R.id.listView1);

        View header = (View)getLayoutInflater().inflate(R.layout.listview_header_row, null);
        listView1.addHeaderView(header);

        listView1.setAdapter(adapter);
    }

any help will be appreciated
Thanks

Answer 1

You need to attach OnItemClickListener

listView1.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView <?> adapterView, View view, int position, long id) {
        // position is index of the row that was clicked
    }
});
