@Override
public void onCreate(Bundle
savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Gallery gallery = (Gallery)
findViewById(R.id.gallery1);
selectedImage = (ImageView)
findViewById(R.id.image1);
tv_name = (TextView)
findViewById(R.id.tv_name_date);
tv_description = (TextView)
findViewById(R.id.tv_discription);
gallery.setSpacing(2);
gallery.setAdapter(new
GalleryImageAdapter(this));
selectedImage.setImageResource(mImageIds[0]);
tv_name.setText(leadersNames[0]);
tv_description.setText(descript[0]);
// clicklistener for Gallery
gallery.setOnItemClickListener(new
OnItemClickListener() {
public void
onItemClick(AdapterView<?> parent, View v,
int position,
long id) {
// show the selected
Image
selectedImage.setImageResource(mImageIds[position]);
tv_name.setText(leadersNames[position]);
tv_description.setText(descript[position]);
}
});
}
}
2. Edit activity_main.xml
<LinearLayout 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"
android:background="#004c00"
android:orientation="vertical"
tools:context="{relativePackage}.${activityClass}" >
<Gallery
android:id="@+id/gallery1"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ImageView
android:id="@+id/image1"
android:layout_width="wrap_content"
android:layout_height="150dp"
android:layout_weight="1"
android:paddingBottom="5dp"
android:paddingRight="10dp"
android:paddingTop="5dp"
android:layout_gravity="left"
android:src="@drawable/muhammad_ali_jinnah" />
<TextView

android:layout_height="wrap_content"
android:padding="5dp"
android:textColor="#fff"
android:scrollbars="vertical"
android:text="TextView" />
</LinearLayout>
3. Create class GalleryImageAdapter.java
package
skk.pak.gallery;
import
android.content.Context;
import
android.view.View;
import
android.view.ViewGroup;
import
android.widget.BaseAdapter;
import
android.widget.Gallery;
import
android.widget.ImageView;
public class
GalleryImageAdapter extends BaseAdapter {
private Context mContext;
public GalleryImageAdapter(Context
context) {
mContext = context;
}
public int getCount() {
return
MainActivity.mImageIds.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
// Override this method according to your
need
public View getView(int index, View view,
ViewGroup viewGroup) {
// TODO Auto-generated method stub
ImageView i = new
ImageView(mContext);
i.setImageResource(MainActivity.mImageIds[index]);
i.setLayoutParams(new
Gallery.LayoutParams(200, 200));
i.setScaleType(ImageView.ScaleType.FIT_XY);
return i;
}
}
