How to disable behind view click event Framelayout

How to disable behind view click event Framelayout - android

Here i have one view pager activity which has one imageview and 2 overlay bars. there overlay bars i made using android xml file layout itself.
Here my requirement is like that
1) single tap on view pager's imageview first time = show top and bottom rectangle overlaybar.
2) single tap on view pager's imageview second time = hide these overlays.
These both are functions like android gallary view type.
But here when these top and bottom layout bar displays at that time i want to use only buttons click only which buttons are declare within this layout.
But I am not getting success to achieve this thing.
Problems
1) when top or bottom bar is there if i can click on next or previous button than its takes event for behind imageview single tap touch event, And my bar is getting invisible.
2) Only wants declare buttons event only
3) Avoid imageview getting clicked when i touch to overlay bar.
In short when my top and bottom image bar appears at that time no touh event takes place for imageview from top and bottom image bar. I can click on imageview but not making clickable when i click on actually next or previous or share button.
So these are the problems which i am facing, Please help me .

A better way is to set the top and bottom frame to be clickable, with:
android:clickable="true"
Doing so will make sure that the view/frame itself will trap all clicking events, and will not pass it through the view behind it. Note this method works for all layout/view/controls, but many controls (such as buttons) already have this function on by default.

android:clickable="true" for top and bottom bar.
or give each FrameLayout an onClickListener.

just add this to each of your framelayout view containers so that absorb the click:
android:clickable="true"
android:focusable="true"
android:focusableInTouchMode="true"

By default, some controls have clickable property as true.
But the layout doesn't. For layout, we have to make them explicitly clickable so that it will grab the events of clicks or touches and will not let it pass to background views. This is how we do it:
android:clickable="true"
android:focusable="true"
android:focusableInTouchMode="true"
Add these lines to all your layouts, so that it will grab/absorb events and will not let it pass to background views.

#gordon1hd1 answer is correct but for those who are still confused, I am adding my layout which contains a FrameLayout as parent and a LinearLayout and twoImageViews as childs.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/scroll_parent"
android:orientation="horizontal" />
<ImageView
android:id="#+id/ivArrowLeft"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="4dp"
android:src="#drawable/actionbar_back"
android:layout_gravity="left|center_vertical"
android:background="#3f808080"
android:clickable="true"
/>
<ImageView
android:id="#+id/ivArrowRight"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="4dp"
android:src="#drawable/actionbar_back"
android:layout_gravity="right|center_vertical"
android:background="#3f808080"
android:rotation="180"
android:clickable="true"
/>
</FrameLayout>
Previously, the Linearlayout was also intercepting touch events when either of ImageViews were pressed. Adding android:clickable="true" to both ImageViews resolved the issue.
If you are also facing this type of issue, add android:clickable="true" to the view you want to trap the clicking event.

Simply, Set android:clickable="true" in xml to your foreground view.

imageView.setSingleTapListener(new OnImageViewTouchSingleTapListener() {
#Override
public void onSingleTapConfirmed() {
Log.d("TAG", "setSingleTapListener");
sCounter++;
if (sCounter % 2 == 0) {
mRlTopOverlayBar.setVisibility(View.GONE);
mRlBottomOverlayBar.setVisibility(View.GONE);
pager.requestFocus();
} else {
mRlTopOverlayBar.setVisibility(View.VISIBLE);
mRlBottomOverlayBar.setVisibility(View.VISIBLE);
mRlTopOverlayBar.requestFocus();
mRlBottomOverlayBar.requestFocus();
mRlBottomOverlayBar.setClickable(true);
mRlTopOverlayBar.setClickable(true);
}
}
});

Add android:clickable="true" to rl_bottom_overlay and rl_top_overlay. If you don´t set click events to these layouts (nor via XML neither programatically), no events will be triggered on background views.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="#+id/llSettings"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="right"
android:background="#ff106279"
android:minHeight="25px"
android:minWidth="25px"
android:onClick="click"
android:orientation="vertical"
android:visibility="visible">
<LinearLayout
android:id="#+id/llSettings1"
android:layout_width="200dp"
android:layout_height="match_parent"
android:layout_gravity="right"
android:background="#ff000f"
android:clickable="true"
android:minHeight="25px"
android:minWidth="25px"
android:orientation="vertical"
android:visibility="visible">
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:onClick="buttonclick"
android:text="New Button" />
</LinearLayout>
</RelativeLayout>
and
public void click(View v) {
Toast.makeText(this, "((RelativeLayout)v).toString()", Toast.LENGTH_SHORT).show();
}
public void buttonclick(View v) {
Toast.makeText(this, "Button", Toast.LENGTH_SHORT).show();
}

// For removing click event, sometime click=true not work
relBottomConfirm.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
return;
}
});

Strange Situation While Working With Team Blox TreeView

I have been working with Team Blox TreeView for about 3 month now with no issues, but after the update from 0.1.0 to (0.1.1 or 0.1.2), I have experienced the following strange situation. I have tried to reproduce the situation I have been experiencing using the code below:

6) In the code above, I have created two TreeViews (one directly inside activity and another one inside a drawer in this activity) with one block each. First TreeView block contains data starting with A (A , A1 , A2 , ...), where as Second TreeView block contains data starting with B (B , B1 , B2 , ...). The idea here is that I'm trying to change the data of first TreeView block and second TreeView block at the same time by clicking a button from inside the drawer (b_treeview_in) and selecting data from a list which opens. The above code works properly (data of both TreeView blocks is getting updated) in version 0.1.0 of this library, but not working properly (First TreeView block data is getting updated, but the second TreeView block data is not) after the update to version (0.1.1 or 0.1.2). Note: In both cases if I check the data, I find that it changed to what was selected from the list, but visually in case of the second TreeView block it didn't change to what was selected.
7) If this problem is caused by notifyDataChanged() or adapter.getNode(), then why is it working for the first TreeView block?
8)
In case of version 0.1.0
In case of version 0.1.1 or 0.1.2

Developer of TreeView here!
Unfortunatly this issues was causes by the library. I uploaded a new Version, which should fix it. Please try it out.

Fragment doesn't respect match parent height when having listview row item has hidden view in it

I am having a weird issue in my app. In one of my app activity I am inflating three fragments in it with tabs. Everything works fine.
In the fragment in which I am having problem, I have listview which is inflated using adapter and data fro web service. This also works well. Now the problem is this the row which is inflated in adapter, has a hidden view which has visibility=gone in xml. On tap of imageview from that row I make that layout visible through java code. The problem is layout doesn't become visible on tap. I have even set breakpoint on the onClickListener of imageview and it does execute the line which changes the visibility from gone to visible. I am unable to understand what is causing this issue as I am using the same row xml with same data in other screen and there it is working perfectly.
UPDATE
I got to know what's causing this issue but don't know how to solve this. In my activity I am having three fragments. The view that I provided for fragment(in which fragment will be inflated) is causing main problem. I have set height width to match parent but it is not taking match parent height. If the fragment just includes normal views like textview, imageview then also fragment is shown properly.But the problem is if fragment consists of listview, then it only takes height of the custom row that is supplied to the listview. I am able to scroll complete listview in that space.
I don't understand what is causing this behaviour.
My Updated code.

Here are the screenshots of the problem
Comparing both images you can see that the hidden view appears in the space of the single row item and is scroll able completely in that space.

Better upshot were targeted at plus for android developers (Cristophe Beils):
"Your ListView must have its height set to match_parent or a fixed size, not wrap_content.
If you need to add another view fixed at the bottom of the ListView as a footer, you need to put both the ListView and the footer View in a vertical LinearLayout and set layout_height to 0dp and layout_weight to 1 on the ListView so that it takes the remaining vertical space."

Try fillViewPort=true on the list view.. But not sure what why yoi have a scroll view inside a list view.. Could be the issue too.

Try setting match_parent as the height of the listview
I suspect this will force the list view to have a defined height and fix your problem.

view inside tool bar not getting clicked

In my app I'm using a Toolbar. Now in inside my Toolbar I have two ImageViews. When the user clicks on any of the ImageViews I open different Fragment or Activity but in my case I'm not able to click on any of the ImageViews.

You can't access the UI element in onCreateView method - EVER
Use onActivityCreated method , that tell the fragment the activity is fully created and ready to interact.
#Override
public void onActivityCreated(Bundle savedInstanceState)
{
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
ImageView ivAboutUs = (ImageView) view.findViewById(R.id.iv_home_about_us);
ivAboutUs .setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
}
});
}

This might be an issue where the touch events never reach the ImageViews because they were absorbed by something else. I ran into something similar where I was trying to put an onClickListener on an Imageview embedded in a list item. No matter how much I clicked on the imageView, something else was eating up the touch events(Most likely the View that makes up the ListView Item. I fixed the problem by changing the ImageView to an ImageButton and setting its background to null (So that the imageButton would look like an imageView and not an image button.) Once I did that, clicking the images worked for me. Try changing your ImageViews to look like this:
<ImageButton
android:id="#+id/iv_home_about_us"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_centerVertical="true"
android:background="#null"
android:src="#drawable/about" />
<ImageView
android:id="#+id/iv_home_search"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_alignTop="#+id/iv_home_about_us"
android:layout_marginRight="10dp"
android:background="#null"
android:src="#drawable/search" />
I hope this helps. Good luck.

ViewHolder messing Views

I have implemented both a ViewHolder and a convertView in my listView.
My listView is populated by a custom adapter, with a list of bookings.
When I click on an item, an invisible layout slides in from right to left, to display buttons.
I can dismiss this overlaying layout by clicking on a dismiss button so that it gets hidden again.
On this overlaying layout, I have a delete Button, which enables me to delete the item.
So far so good.
When I erase an item the item disappears as expected, the adapter is then reloaded.
The item below takes the position of the deleted item, but remains invisible.
I know it is here, because I can still click on the item to trigger the overlaying View.
So the ovelaying view is visible but not the item. I have no idea why this is happening.
I suspect the ViewHolder to be responsible of this behaviour, but I can't find a solution.
Thank you for your help.

Your problem comes from re-using the convertView.
When the previous item got a click the OnClickListener fired and in there the visibility for the item was set to GONE. Later on this same view got recycled and passed to getView() as the convertView. Because you are re-using it without resetting any changes that were made you are now working with a View for a new item that is not in a known state. You should make sure you undo any changes before using a convertView.
The quick fix is to not re-use the convertView that is passed into getView(). So, in your code where you check if you can re-use the convertView:
if(convertView == null)
Sabotage that check just to see if things start working:
if(true)
If that does the trick you will probably want to fix it properly.
In the else clause of the above check, you are getting the item holder from the tag. Also undo any changes that your OnClickListeners could have made. You want to start with a View for a new item in a known state. You should initialize it explicitly. For example:
if(convertView == null) {
// ... snipped all the initialization ...
} else {
holder = (ViewHolder)convertView.getTag();
convertView.setVisibility(View.VISIBLE);
}
Update
I have never used a 'heterogenous' adapter so I can't really answer why "the convertView is reusing the overlay View instead of my item's root View." The Android developer documentation for Adapter.getView() says about the convertView argument:
The old view to reuse, if possible. Note: You should check that this view is non-null and of an appropriate type before using. If it is not possible to convert this view to display the correct data, this method can create a new view. Heterogeneous lists can specify their number of view types, so that this View is always of the right type (see getViewTypeCount() and getItemViewType(int)).
The emphasized bit says that you cannot depend on the system to pass you a convertView of the right type, while the last sentence says the opposite (as I read it).
Basically, I don't know why it's not working. I guess in the test where you check if you must inflate a new view yourself
if(convertView == null)
you should also check if it is the right kind of view:
if(convertView == null || getItemViewTypeFromView(convertView) != type)
Where getItemViewTypeFromView() is something like this:
private int getItemViewTypeFromView(View view) {
switch (view.getId()) {
case R.id.item_layout_root:
return TYPE_ITEM;
case R.id.placeholder_layout_root:
return TYPE_PLACEHOLDER;
default:
throw new UnsupportedOperationException();
}
}
In the item and placeholder layouts, give the root elements an id so you distinguish between them. So something like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/item_layout_root"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="5dp"
android:paddingLeft="5dp"
android:paddingRight="5dp" >
... snipped the elements that make up the body of the layout ...
</RelativeLayout>
I haven't tried the above, so I hope it works for you.
Good luck!

Show my Fragment in Dialog android

I have a class that extends a Fragment. I want when press a button from An Activity to opens this Fragment with its layout in dialog in addition to that the fragment opens normally in its place. Is this possible?
This is my Fragment (TipsFragment.java)

Since Android supports nesting Fragments (available in the support library) you could show your TipsFragment as a content of another DialogFragment. Avoid this solution whenever possible.
A better solution would be to make TipsFragment extend DialogFragment and that way you can either show the Fragment inline or in a dialog.
1 - Make TipsFragment extends DialogFragment
public class TipsFragment extends DialogFragment {...}
2 - On button click use FragmentTransaction.add or FragmentTransaction.replace to show the DialogFragment inline or include it in your layout and change its visibility.
3 - Show the TipsFragment as a dialog
TipsFragment fr = new TipsFragment();
fr.show(getSupportFragmentManager(), "dialog_fragment_tag");

How to disable behind view click event Framelayout - android

android:clickable="true" for top and bottom bar. or give each FrameLayout an onClickListener.

just add this to each of your framelayout view containers so that absorb the click: android:clickable="true" android:focusable="true" android:focusableInTouchMode="true"

Simply, Set android:clickable="true" in xml to your foreground view.

Add android:clickable="true" to rl_bottom_overlay and rl_top_overlay. If you don´t set click events to these layouts (nor via XML neither programatically), no events will be triggered on background views.

// For removing click event, sometime click=true not work relBottomConfirm.setOnClickListener(new OnClickListener() { #Override public void onClick(View view) { return; } });
