}

my problem can not able click image or video thumbnail. how able image when checked check box.

here xml code image_selection:-

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent"            android:layout_height="fill_parent" android:orientation="vertical" android:gravity="center_horizontal">          <imageview  android:id="@+id/item_grid" android:layout_width="100dip" android:layout_height="100dip"/>          <checkbox android:id="@+id/check" android:layout_width="wrap_content" android:layout_height="wrap_content" /> 

and grid_gallery.xml:-

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <gridview xmlns:android="http://schemas.android.com/apk/res/android"      android:id="@+id/sdcard"     android:layout_width="fill_parent"      android:layout_height="fill_parent"     android:padding="10dp"     android:verticalspacing="10dp"     android:horizontalspacing="10dp"     android:numcolumns="auto_fit"     android:columnwidth="90dp"     android:stretchmode="columnwidth"     android:gravity="center" /> </relativelayout> 

please me. in advance

it seems store image path in arraylist list. if so, set onitemclicklisteber gridview. in onitemclick method position of gridview clicked. try 'list.get(position)in theonitemclick` path
