Android : Change the background when clicked on spinner

I have 3 spinner for country, timezone and language with the respective labels arranged one below another in below manner
Label1 Spinner1
Label2 Spinner2
Label3 Spinner3
When Click on say Spinner1, I want entire row i.e. Label and spinner to change their background color, Say if I take it in a LinearLayout So on spinner click The background should change to blue
I want probably a xml way of changing background of whole layout and not programmatic as I will have to code for each spinner
Can someone tell me how do I change entire layout color on just spinner click
I tried Spinner.setOnItemSelectedListener, but that is hitting only when I select some item, but I want the layout to change color even on press of Spinner
Spinner in layout
layout.xml
<LinearLayout
android:id="#+id/linearlay"
android:layout_width="320dp"
android:layout_height="40dp"
android:background="#drawable/bg_spinner_pressed">

Settings.java file
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Log.e("Techie","----------------------------citizenship1----------------------------");
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
Log.e("Techie","----------------------------citizenship2----------------------------");
}
});
I expect the Layout with id linearlay should change its primary color white to change to Blue on spinner click. please help

Call setonTouchListener and handle down and up events to change the colors
spinner.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
Log.e("Techie", "----------------------------Action down----------------------------");
layout.setBackgroundColor(ContextCompat.getColor(mContext, R.color.color1));
break;
case MotionEvent.ACTION_CANCEL:
Log.e("Techie", "----------------------------Cancel----------------------------");
layout.setBackgroundColor(ContextCompat.getColor(mContext, R.color.color2));
break;
}
// allow target view to handle click
return false;
}
});

Android : flowlayout inner button with close icon onclick event

I have a requirement to create a button with close icon like as below:
i have use button and i have fatch problem when i click on button remove button.
but my requirement is onclick close icon when remove form list.
so please help me which control use so my problem solution.

Use this code it will solved your problem
buttondelete.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
final int DRAWABLE_RIGHT = 2;
if(event.getAction() == MotionEvent.ACTION_UP) {
if(event.getRawX() >= (buttondelete.getRight() - buttondelete.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
// your action here
return true;
}
}
return false;
}
});

i would add to flow layout customLaout which contains of grey background and linear layout with 2 elements inside. TextView and ImageView.
Both has own ClickListeners
something like:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#android:color/darker_gray"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_gravity="center"
android:text="Example Text"
android:id="#+id/buttonTextView"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:id="#+id/buttonExitIcon"
android:src="#drawable/your_image_source"
/>
</LinearLayout>
and add Click listeners for both imageView and TextView

{
RelativeLayout mainView = (RelativeLayout)findViewById(R.id.item);
View child = getLayoutInflater().inflate(R.layout.child, null);
Button bt_close = (Button)child.findviewById(R.id.btnclose);
bt_put.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
RelativeLayout pView = (RelativeLayout)v.getParent();
mainView.removeView(pView);
}
});
mainView.addView(child);
}
Create a child.xml using the RelativeLayout with childs (TextView for text and Button as Remove button)
Inflate the xml layout , add each views into your main_layout and
setonclicklistner to button.
when clicked on button , get the parent view from the clicked view and remove the view from main_layout.
this may help you.

I want to set a transparent background layer when I click on the floating action menu.

This is what I have done so far. Created FloatingActionButton. Now As the + icon is pressed a translucent layer should be there at the back.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.getbase.floatingactionbutton.FloatingActionsMenu
android:id="#+id/actionMenu"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_marginBottom="60dp"
fab:fab_addButtonColorNormal="#color/primary"
fab:fab_addButtonColorPressed="#color/primary_dark"
fab:fab_addButtonPlusIconColor="#ffffff">
<com.getbase.floatingactionbutton.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="openAudio"
fab:fab_colorNormal="#EA1E63"
fab:fab_colorPressed="#EA1E63"
fab:fab_icon="#drawable/ic_action_mic" />
</com.getbase.floatingactionbutton.FloatingActionsMenu>
</RelativeLayout

Try this.
floatingActionMenuButton.setOnMenuToggleListener(new FloatingActionMenu.OnMenuToggleListener() {
#Override
public void onMenuToggle(boolean opened) {
if (opened) {
//menu opened
} else {
//menu closed
}
}
});

use setBackgroundResource or setBackgroundColor. I think first is pretty simple.
Second one takes an int as an argument. So, just convert your hex color (for example #55000000) into decimal and it will work as well.

I had the same issue and i fixed it in following way.
I added a relative layout which will match parent in both width and height.
Set its background color to black and set alpha to your required opacity.
<RelativeLayout
android:id="#+id/obstructor"
android:visibility="invisible"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:alpha="0.75"
android:background="#android:color/black">
</RelativeLayout>
And then on the menu item expanded and collapsed make this visible and invisible.
mFabMenu = (FloatingActionsMenu) findViewById(R.id.multiple_actions);
final RelativeLayout obstrucuterView = (RelativeLayout) findViewById(R.id.obstructor);
obstrucuterView.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (obstrucuterView.getVisibility() == View.VISIBLE) {
mFabMenu.collapse();
return true;
}
return false;
}
});
mFabMenu.setOnFloatingActionsMenuUpdateListener(new FloatingActionsMenu.OnFloatingActionsMenuUpdateListener() {
#Override
public void onMenuExpanded() {
if (obstrucuterView.getVisibility() == View.INVISIBLE)
obstrucuterView.setVisibility(View.VISIBLE);
}
#Override
public void onMenuCollapsed() {
if (obstrucuterView.getVisibility() == View.VISIBLE)
obstrucuterView.setVisibility(View.INVISIBLE);
}
});
Hope this helps.

There is another custom library which is more advanced than what you are using right now.
Get it here
Clans floating Action Button
Set this to true and it will solve your problem. Do let me know if it helps
fabPlusButton.setClosedOnTouchOutside(true);

If you are using Clans floating Action Button then perhaps fab:menu_backgroundColor might be something that you could have a look at if it satisfies your use-case. ofcourse the layout width and height should both match parent (This solution has worked for me)

ListItem should change bg color, color of text and images on it while pressed

I have a ListView, where each item has a custom LinearLayout with a bg image, a textView and 2 imageViews.
Now I need that while the user is touching the item, all of those switch to the "pressed" state:
the bg image of the LiearLayout must be replaced with another one
the TextView should change textColor
both ImageViews in the item should switch to alternative images
Normally such stuff would be done using an xml resource with selector inside, e.g. the LinearLayout would use a drawable with selector inside for background, the TextView a drawable with selector and colors for textColor, and ImageViews use selector with images inside for src.
The problem is that the pressed state is only detected by the LinearLayout and not by the child views (?), so only the background image changes.
I've tried implementing this using OnTouchListener, but then comes the problem that I can't securely get access to Views inside the list item.
I tried caching the view which I return in getView() of the list item to then later change the images and text color. This works usually, but e.g. if one of the list items opens another activity, then the view somehow gets lost and the highlighted state stays indefinitely. I've tried debugging and it works correctly if I step thru with the debugger.
Also, reusing the cachedView seems to bring no good and messes things up completely, so I'm just inflating a new view for the list item each time (this must be inefficient).
Just in case, here is the code of the custom list item item i'm using for the custom list adapter:
public class MyListItem extends AbstractListItem
{
private int iconResource, iconHighlightedResource;
private int textResource;
private View.OnClickListener onClickListener;
private LinearLayout currentView;
private ImageView imgIcon;
private TextView txtText;
private ImageView imgArrow;
private boolean bIsHighlighted;
public MyListItem(int iconResource, int iconHighlightedResource, int textResource, View.OnClickListener onClickListener)
{
this.iconResource = iconResource;
this.iconHighlightedResource = iconHighlightedResource;
this.textResource = textResource;
this.onClickListener = onClickListener;
}
public View getView(View cachedView)
{
this.currentView = buildView();
populateView();
update();
return this.currentView;
}
private LinearLayout buildView()
{
LayoutInflater inflater = (LayoutInflater)App.get().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
return (LinearLayout)inflater.inflate(R.layout.my_menu_item, null);
}
private void populateView()
{
this.imgIcon = (ImageView)this.currentView.findViewById(R.id.img_menu_item_icon);
this.txtText = (TextView)this.currentView.findViewById(R.id.txt_menu_item_text);
this.txtText.setText(this.textResource);
this.txtText.setTypeface(App.fontCommon);
this.imgArrow = (ImageView)this.currentView.findViewById(R.id.img_menu_item_arrow);
this.currentView.setOnClickListener(this.onClickListener);
this.currentView.setOnTouchListener(this.highlighter);
}
private View.OnTouchListener highlighter = new View.OnTouchListener()
{
#Override
public boolean onTouch(View v, MotionEvent event)
{
int nAction = event.getAction();
int nActionCode = nAction & MotionEvent.ACTION_MASK;
switch (nActionCode)
{
case MotionEvent.ACTION_DOWN:
bIsHighlighted = true;
update();
break;
case MotionEvent.ACTION_UP:
case MotionEvent.ACTION_CANCEL:
bIsHighlighted = false;
update();
break;
}
return false;
}
};
private void update()
{
if (this.bIsHighlighted)
{
updateForHighlightedState();
}
else
{
updateForNormalState();
}
}
private void updateForHighlightedState()
{
Resources r = App.get().getResources();
this.currentView.setBackgroundResource(R.drawable.button_beveled_m_call_to_action_taking_input);
this.imgIcon.setImageResource(this.iconHighlightedResource);
this.txtText.setTextColor(r.getColor(R.color.white));
this.imgArrow.setImageResource(R.drawable.arrow_highlighted);
}
private void updateForNormalState()
{
Resources r = App.get().getResources();
this.currentView.setBackgroundColor(r.getColor(R.color.white));
this.imgIcon.setImageResource(this.iconResource);
this.txtText.setTextColor(r.getColor(R.color.text_dark));
this.imgArrow.setImageResource(R.drawable.arrow);
}
}
Here is the layout file (xml):
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="#color/white"
android:gravity="center_vertical"
android:padding="5dp" >
<ImageView
android:id="#+id/img_menu_item_icon"
android:layout_width="48dp"
android:layout_height="48dp"
android:src="#drawable/info" />
<TextView
android:id="#+id/txt_menu_item_text"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="24dp"
android:text="Menu item"
android:textColor="#color/text_dark"
android:layout_marginLeft="5dp" />
<ImageView
android:id="#+id/img_menu_item_arrow"
android:layout_width="48dp"
android:layout_height="48dp"
android:src="#drawable/arrow" />
</LinearLayout>

After lots of experimenting finally this worked:
Every child view inside the list item layout must have android:duplicateParentState="true".
Then all of them can just use selector drawables. No extra effort inside the code is required.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="#drawable/my_item_bg"
android:gravity="center_vertical"
android:padding="5dp" >
<ImageView
android:id="#+id/img_menu_item_icon"
android:layout_width="48dp"
android:layout_height="48dp"
android:src="#drawable/selector_info"
android:duplicateParentState="true" />
<TextView
android:id="#+id/txt_menu_item_text"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="24dp"
android:text="Menu item"
android:textColor="#drawable/selector_color_my_button_text"
android:layout_marginLeft="5dp"
android:duplicateParentState="true" />
<ImageView
android:layout_width="48dp"
android:layout_height="48dp"
android:src="#drawable/selector_arrow"
android:duplicateParentState="true" />
</LinearLayout>

You should create custom drawable selectors, and set them as the background to your listview element.
Step#1, create another layout (named: layout_selected for this example), with the appropriate background color for your pressed state (like the layout file you supplied, but with the background attribute of the linear set to another color).
Then you will define a drawable selector, which will be placed in your drawable folder), defining which background should be use in which instance. This will look something like this:
<!-- pressed -->
<item android:drawable="#drawable/layout_selected" android:state_pressed="true"/>
<!-- focused -->
<item android:drawable="#drawable/layout_normal" android:state_focused="true"/>
<!-- default -->
<item android:drawable="#drawable/layout_normal"/>
Finally, to use this in your list, when you set the layout for your adapter, set it to the selector we just created, instead of your standard layout.
Maybe a little hard to explain, but you want to use 'Drawable Selectors' to accomplish what you want.

I would suggest to add ViewHolder pattern for listview. This will optimize your listview drawing & creating UI.
Also in that we can use setTag to save instance of row. In that you can handle touch event.

TextView selection with Spannable and LinkMovementMethod

What i did so far is a list view of textviews having the normal text and clickable spans:
Clicking the span i'm opening the URL, clicking the item View around the textView leads to the listView OnItemClickListener navigating to the item details, that's fine:
Now the problem is:
touching the textView makes the normal text be kinda highlighted (with the same color it has when the item is selected completely), textView's OnTouchListener touch event fires but not OnFocusChangeListener event and the item's View does not get the selection style. Tried all the variations of FOCUS_BLOCK_DESCENDANTS for listView, item View, the textView focusable was enabled or disabled with the same result.
Fortunately, textView OnClickListener event fires this way, but that's so ugly: the text is invisible while the touch is not released as the selected text color is the same as the item color, there's no other indication that the user is going to the item details other than that ugly text vanishing.
I suspect that happens because the content of the textView is Spannable, and the parts which are not CliclableSpan-s behave in this strange way.
Any chance i could select the item once the normal text is touched ?
The listView item layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:descendantFocusability="blocksDescendants"
android:orientation="horizontal" >
<ImageView
android:id="#+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginBottom="5dp"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:layout_marginTop="5dp"
android:focusable="false" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/title"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="5dp"
android:layout_marginTop="5dp"
android:focusable="false"
android:text=""
android:textAppearance="?android:attr/textAppearanceLarge"
android:textStyle="bold" />
<TextView
android:id="#+id/info"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="4dp"
android:layout_marginLeft="4dp"
android:layout_marginRight="4dp"
android:focusable="false"
android:text=""
android:textAppearance="?android:attr/textAppearanceSmall" />
<TextView
android:id="#+id/details"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="4dp"
android:layout_marginLeft="4dp"
android:layout_marginRight="4dp"
android:focusable="false"
android:gravity="fill_horizontal|right"
android:text=""
android:textAppearance="?android:attr/textAppearanceMedium"/>
</LinearLayout>
</LinearLayout>
With the text view setClickable(false) i'm able to disable this weird selection style in the way that nothing happens while touching the text view area, not good but might be useful for solution.
Also tried to add not focusable & not clickable button to each item, when it's touched the complete item is selected and when touch is released the item's click event is passed, that's exactly what i expected from the textView with Spannable content.

Did you try setting the background of your TextView to Android's default list_selector_background?
textView.setMovementMethod(LinkMovementMethod.getInstance());
textView.setBackgroundResource(android.R.drawable.list_selector_background);
For me it seems to give the result that you want.
UPDATE: After seeing that the item is not just a single TextView
Well, this is not a perfect solution (since it's probably better to fix the TextView - ListView highlighting interaction somehow), but it works well enough.
I figured out that instead of setting the movement method on the TextView (that triggers the issue), it is just simpler to check in the ListView's onItemClick() (after a click is definitely confirmed) to see if we should launch the onClick() on our ClickableSpans:
public class MyActivity extends Activity {
private final Rect mLastTouch = new Rect();
private boolean spanClicked(ListView list, View view, int textViewId) {
final TextView widget = (TextView) view.findViewById(textViewId);
list.offsetRectIntoDescendantCoords(widget, mLastTouch);
int x = mLastTouch.right;
int y = mLastTouch.bottom;
x -= widget.getTotalPaddingLeft();
y -= widget.getTotalPaddingTop();
x += widget.getScrollX();
y += widget.getScrollY();
final Layout layout = widget.getLayout();
final int line = layout.getLineForVertical(y);
final int off = layout.getOffsetForHorizontal(line, x);
final Editable buffer = widget.getEditableText();
final ClickableSpan[] link = buffer.getSpans(off, off, ClickableSpan.class);
if (link.length == 0) return false;
link[0].onClick(widget);
return true;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// ...
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (spanClicked(listView, view, R.id.details)) return;
// no span is clicked, normal onItemClick handling code here ..
}
});
listView.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP) {
mLastTouch.right = (int) event.getX();
mLastTouch.bottom = (int) event.getY();
}
return false;
}
});
// ...
}
}
The spanClicked() method is basically an abbreviated version of the LinkMovementMethod's onTouchEvent() method in the framework. To capture the last MotionEvent coordinates (to check for the click event), we simply add an OnTouchListener on our ListView.

Use TextView's setHighlightColor(Color.TRANSPARENT);

I think best way to solve this problem is using a selector. you can chan selection backgroun color so they will seen same
example selector code:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:color="#000000" /> <!-- pressed -->
<item android:state_focused="true"
android:color="#000000" /> <!-- focused -->
<item android:color="#FFFFFF" /> <!-- default -->
</selector>
implement sth like that to your link.
let me know about result

Quote from documentation of the setMovementMethod() of TextView
Sets the movement method (arrow key handler) to be used for this
TextView. This can be null to disallow using the arrow keys to move
the cursor or scroll the view.
Be warned that if you want a TextView
with a key listener or movement method not to be focusable, or if you
want a TextView without a key listener or movement method to be
focusable, you must call android.view.View.setFocusable(boolean) again
after calling this to get the focusability back the way you want it.
The second paragraph explains that we should explicitly call the setFocusable method after setting the LinkMovementMethod to get focusability working the way we want.
You need to do it in code after inflating the list item.
Once you are able to get the focus, you can set the selector to have a different color text.
Here is the source code of setMovementMethod.
