Hi in my application i am using the Viewpager with PagerAdapter. it contains n number of images. but when i rotate the device when viewpager is on first image then the image shift to top left corner and appears very small. please have a look in the attached image.
code which i am using
public class CustomViewPager extends ViewPager {
private final long SWITCH_TIME_INTERVAL = 5000;
public CustomViewPager(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
public CustomViewPager(Context context, AttributeSet attributeSet) {
super(context, attributeSet);
postDelayed(mSwither, SWITCH_TIME_INTERVAL);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int height = 0;
for (int i = 0; i < getChildCount(); i++) {
View child = getChildAt(i);
child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
int h = child.getMeasuredHeight();
if (h > height)
height = h;
}
heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
/**

}else
{
count++;
}

when i run my app my footer view is left possition.in my option i have problem in activity_main.xml file because footerView's xml is correct.what is a wrong if anyone knows solution please help me
thanks everyone

Property layout_gravity affects an element aligning it relative to its parent, while gravity property aligns child views of that view. Example:
If you apply
android:gravity="center"
android:layout_gravity="left"
to a TextView it means that TextView container will be aligned left and the text inside will be centered.
Catch 22:
When you add your footer layout to ListView, it may have a RelativeLayout parent, and RelativeLayout does not support the layout_gravity property. In that case, fix would be to add:
layout_centerHorizontal="true"
layout_alignParentBottom="true"
to the root of your footer layout.

ListView setOnItemClickListener not work

Sorry for my english. I spend many times but i cant fix my problem. I have listView and i want set setOnItemClickListener him. This is my listView:
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id = "#+id/listScene"
android:clickable="true"
android:cacheColorHint="#00000000"
android:divider="#adb8c2"
android:dividerHeight="1dp"
android:scrollingCache="false"
android:smoothScrollbar="true"
>
</ListView>
Its my code
public void outputListView(ArrayList<String> list) {
Adapter adapter = new Adapter(getApplicationContext(), R.layout.item, list);
adapter.notifyDataSetChanged();
listView.setAdapter(adapter);
listView.setItemsCanFocus(false);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
Toast.makeText(getApplicationContext(), String.valueOf(position), Toast.LENGTH_SHORT).show();
}
});
}
but when i click in item its nothing happens

I can not delete it, because I need it in the project. I do not know how to fix this situation

Sometimes the ListView click doesn't work. And at this case you might have to add one more attribute.
android:descendantFocusability="blocksDescendants"
Add this attribute to the top most layout of your XML where you have provided the ListView elements.

In your ListView remove the xml attribute android:clickable="true"
This is taking your click event and not sending it down to the child views.
Edit
You are passing in getApplicationContext() which is the wrong context. The listener does work, but the Toast is not displaying in the right context. You need to pass in getContext(). However, since this is an Activity, you can just pass in this instead.
public void outputListView(ArrayList<String> list) {
Adapter adapter = new Adapter(this, R.layout.item, list);
adapter.notifyDataSetChanged();
listView.setAdapter(adapter);
listView.setItemsCanFocus(false);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
Toast.makeText(this, String.valueOf(position), Toast.LENGTH_SHORT).show();
}
});
}

ListView cannot scroll

I have tried to scroll the ListView up when the event item is more than the space of the ListView but it fails. I would like to know if I can make the ListView scrollable without adding any listener. Thank you.

If you don't want to use any listener then you can simply use a custom ListView like this,
public class CustomListView extends ListView implements View.OnTouchListener, AbsListView.OnScrollListener {
private static final int MAXIMUM_LIST_ITEMS_VIEWABLE = 99;
private int listViewTouchAction;
public CustomListView (Context context, AttributeSet attrs) {
super(context, attrs);
listViewTouchAction = -1;
setOnScrollListener(this);
setOnTouchListener(this);
}
#Override
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
if (getAdapter() != null && getAdapter().getCount() > MAXIMUM_LIST_ITEMS_VIEWABLE) {
if (listViewTouchAction == MotionEvent.ACTION_MOVE) {
scrollBy(0, -1);
}
}
}
#Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
int newHeight = 0;
final int heightMode = MeasureSpec.getMode(heightMeasureSpec);
int heightSize = MeasureSpec.getSize(heightMeasureSpec);
if (heightMode != MeasureSpec.EXACTLY) {
ListAdapter listAdapter = getAdapter();
if (listAdapter != null && !listAdapter.isEmpty()) {
int listPosition = 0;
for (listPosition = 0; listPosition < listAdapter.getCount()
&& listPosition < MAXIMUM_LIST_ITEMS_VIEWABLE; listPosition++) {
View listItem = listAdapter.getView(listPosition, null, this);
//now it will not throw a NPE if listItem is a ViewGroup instance
if (listItem instanceof ViewGroup) {
listItem.setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
}
listItem.measure(widthMeasureSpec, heightMeasureSpec);
newHeight += listItem.getMeasuredHeight();
}
newHeight += getDividerHeight() * listPosition;
}
if ((heightMode == MeasureSpec.AT_MOST) && (newHeight > heightSize)) {
if (newHeight > heightSize) {
newHeight = heightSize;
}
}
} else {
newHeight = getMeasuredHeight();
}
setMeasuredDimension(getMeasuredWidth(), newHeight);
}
#Override
public boolean onTouch(View v, MotionEvent event) {
if (getAdapter() != null && getAdapter().getCount() > MAXIMUM_LIST_ITEMS_VIEWABLE) {
if (listViewTouchAction == MotionEvent.ACTION_MOVE) {
scrollBy(0, 1);
}
}
return false;
}
}
Then use in your layout,
<CustomListView
android:id="#+id/event_list"
android:scrollbars="vertical"
android:fastScrollEnabled="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_below="#id/titleBar"
android:layout_above="#+id/DelAll" />

I Have made it as a widget and Now finally to add this to your List View use
frame = (QuickReturnRelativeLayoutFooter) newProjectsView
.findViewById(R.id.frame);
frame.attach(projectsList);
where projectList is your List View
example
ListView projectList =(ListView)findViewById(R.id.projectList);
and Voila Cheers Completed Smooth as Heaven .......
