In the below example I have created a ListView in ListView I have added title, subtitle and image. Here first I have added ListView in activity_main.xml layout, then I have created new list_item.xml layout here I have created RelativeLayout, In RelativeLayout I have added ImageView and two TextView. In next step I have created two class first is RowData and second is MyAdapter. MyAdapter extend with BaseAdapter, after then next step: In MainActivity I have used final string method. You can see below program it will clearly describe you "How to add title, subtitle and Image in List View".
Step(1)activity_main.xml-
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
Step(2)-Created a new list_item.xml layout-
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView
android:id="@+id/icon"
android:layout_width="80dp"
android:layout_height="80dp"
android:contentDescription="@string/image"
android:paddingLeft="10dp"
android:paddingRight="10dp" />
<TextView
android:id="@+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="@+id/icon"
android:paddingBottom="10dp"
android:textColor="#CC0033"
android:textSize="16dp" />
<TextView
android:id="@+id/subtitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/title"
android:layout_toRightOf="@+id/icon"
android:paddingLeft="10dp"
android:textColor="#3399FF"
android:textSize="14dp" />
</RelativeLayout>
Step(3)- Created a new RowData class
public class RowData {
private int imageId;
private String title;
private String subtitle;
public int getImageId() {
return imageId;
}
public void setImageId(int imageId) {
this.imageId = imageId;
}
public String getSubtitle() {
return subtitle;
}
public void setSubtitle(String subtitle) {
this.subtitle = subtitle;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}
Step(4)- Created MyAdapter class-
public class MyAdapter extends BaseAdapter {
Context context;
List<RowData>rowData;
public MyAdapter(Context context, List<RowData> items) {
this.context = context;
this.rowData = items;
}
/*private view holder class*/
private class ViewHolder {
ImageView imageView;
TextView txtTitle;
TextView txtDesc;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
LayoutInflater mInflater = (LayoutInflater)
context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = mInflater.inflate(R.layout.list_item, null);
holder = new ViewHolder();
holder.txtDesc = (TextView) convertView.findViewById(R.id.subtitle);
holder.txtTitle = (TextView) convertView.findViewById(R.id.title);
holder.imageView = (ImageView) convertView.findViewById(R.id.icon);
convertView.setTag(holder);
}
else {
holder = (ViewHolder) convertView.getTag();
}
RowData rowItem = (RowData) getItem(position);
holder.txtDesc.setText(rowItem.getSubtitle());
holder.txtTitle.setText(rowItem.getTitle());
holder.imageView.setImageResource(rowItem.getImageId());
return convertView;
}
@Override
public int getCount() {
return rowData.size();
}
@Override
public Object getItem(int position) {
return rowData.get(position);
}
@Override
public long getItemId(int position) {
return rowData.indexOf(getItem(position));
}
}
Step(5)-MainActivity-
public class MainActivity extends AppCompatActivity {
public static final String[]titles =new String[]{"GOOGLE","FACEBBOK","TWITTER"};
public static final String[]subtitle=new String[]{"google is large company","Facebook is a socialsite networking","Twitter is indian company"
};
public static final Integer[] images = { R.drawable.one,
R.drawable.two, R.drawable.three };
ListView list;
List<RowData> rowData;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
rowData =new ArrayList<RowData>();
for(int i=0;i<titles.length;i++){
RowData data =new RowData();
data.setImageId(images[i]);
data.setSubtitle(subtitle[i]);
data.setTitle(titles[i]);
rowData.add(data);
}
list = (ListView) findViewById(R.id.list);
MyAdapter adapter = new MyAdapter(this, rowData);
list.setAdapter(adapter);
}
}
