How to load multiple images on the same imageview by clicking a button?

Basically, I want to have an AlertDialog in which multiple images will load on the same ImageView. By clicking the NEXT button it will get the next image bitmap from bitmap list and finally will load on that ImageView. Same case for PREV button. It will take previous bitmap and will load the image on the same ImageView.
But the problem is after loading the first image it does not load the next image. If I click the next button then it takes the next bitmap but the imageview.setImageBitmap(bitmap) does not work.
How to remove or clear the previous image to place the next photos?

}

You need to clear the previous image from imageview and then you can set the new on top.
Do as below
private void displayPhoto() {
if (mCurrentPhotoIndex < mSelectedLocationPhotosBitmap.size()) {
Bitmap bitmap = mSelectedLocationPhotosBitmap.get(mCurrentPhotoIndex);
Toast.makeText(context,""+mCurrentPhotoIndex+" : "+bitmap,Toast.LENGTH_LONG).show();
mSelectedPlaceImages.setImageBitmap(null)
mSelectedPlaceImages.setImageBitmap(bitmap);
setButtonVisibility();
}
}

Try this:
mSelectedPlaceImages.destroyDrawingCache();
mSelectedPlaceImages.setImageBitmap(bitmap);
mSelectedPlaceImages.buildDrawingCache();

Overlaying youtube Api Videos in View Pager

My multiple youtube videos in viewPager overlaying itself and youtubePlayer stops after one second recording. My first video works fine, but whenever I slide to another or back to previous one and try to record it I give an overlaying error. I try to set the videoContainer to gone, release the youtube player, bringToFront() current videoContainer, hide/show detach/attach videoFragment and the problem still remains.The detach/attach fragment solution works but not every time.
My warn message: YouTube video playback stopped due to unauthorized overlay on top of player. The YouTubePlayerView is obscured by android.widget.LinearLayout{54f27e3 V.E...... ........ 0,0-1080,1584 #7f1000ec app:id/globalViewLinearLayout}. Right edge 50 px right of YouTubePlayerView's left edge.

How to avoid startActivty(new Intent()) method starting more than one Activities?

I just do my project but when I test my app I found that then I touch the screen by using more than one fingers my app may start two or three different activities.
The activities all go to the back stack. Is this a bug in Android framework? But I can't reappear this condition, it just happened.
So, have you guys ever have this problem? Please come and discuss with me. If you do; Thanks.
Supply:
And here is My xml file , when I click the different RelativeLayout at the same time , it happened.
I tried this afternoon , but this condition is not appear anymore. Now I am confusing.

You need to define the launch mode. There are at least two ways of solving this by either using the manifest file (hint: singleTop) or by using Intent flags (hint: FLAG_ACTIVITY_SINGLE_TOP).
Good luck!

Simpliest approach would be disable control that starts your Activity (button for example) after 1 click, and enable it later with some condition or action. Try it.

You can use this approach.......
((Button)findViewById(R.id.someButton)).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
((Button)findViewById(R.id.someButton)).setEnabled(false);
}
});
Happy coding

ListView is invisible in Activity

I've a one ListView as shown below, when the program is first executed,then it is visible
later automatically invisible.
This layout is visible when User clicks the Button, before that the Visibility is GONE
<RelativeLayout
android:id="#+id/comments_block"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/header"
android:visibility="gone" >
<TextView
android:id="#+id/comments_subHeadding"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:text="Type your comment"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#color/red" />
<EditText
android:id="#+id/user_commetns"
android:layout_width="match_parent"
android:layout_height="50dip"
android:layout_below="#+id/comments_subHeadding"
android:layout_marginTop="5dip"
android:background="#color/white"
android:imeOptions="actionSend"
android:inputType="textLongMessage" />
</RelativeLayout>
This Layout contains ListView Here I'm facing the problem.
<LinearLayout
android:id="#+id/listview_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/comments_block"
android:background="#color/ios_blue"
android:orientation="vertical">
<ListView
android:id="#+id/comments_list1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="1dip"
android:background="#android:color/transparent"
android:cacheColorHint="#android:color/transparent" >
</ListView>
</LinearLayout>
Activity Code
#Override
public void onClick(View v)
{
if (v == add_comment_button)
{
if(show)
{
comments_block.setVisibility(View.VISIBLE);
show = false;
return;
}
else
{
comments_block.setVisibility(View.GONE);
show = true;
}
}
else if (v == back_comments_button)
{ finish(); }
}

In your code you are doing
android:layout_height="wrap_content", if there are no item in listview then its height will be 0.
So please if you will use match_parent instead of wrap_content
android:layout_height="match_content"
android:layout_weight="1"
Then your listview will be visible.
I hope it will work.

I found the solution for your problem.....
You are just showing and hiding the comments_block only....
you try this one...I hope it will help you definitely...All the bset
#Override
public void onClick(View v)
{
if (v == add_comment_button)
{
if(show)
{
comments_block.setVisibility(View.VISIBLE);
listview_layout.setVisibility(View.GONE);
show = false;
return;
}
else
{
comments_block.setVisibility(View.GONE);
listview_layout.setVisibility(View.VISIBLE);
show = true;
}
}
else if (v == back_comments_button)
{ finish(); }
}
