Make all EditText not editable together

I searched and found ways to make a single EditText not editable, such as
edittext.setKeyListener(null);
set EditText as android:focusable="false"
However, the problem with these methods is that I need to get references to each of the EditText views in my layout and individually implement the above statements. Is there a way by which I can make all EditText views in a layout not editable?
The application is this: I have a 'Display and Edit' activity, where the user is shown the current record in the database. At this point the displayed text should be read only. If required, he clicks an edit button and then the EditText views become editable.
I tried setting android:inputType="none" and android:focusable="false" in the root ViewGroup but that didn't work. Is there a way out?

If you want to achieve this programmatically,
public void setupUI(View view, boolean editable) {
if (view instanceof EditText) {
((EditText)view).setFocusable(editable);
//Here you can add any other code that needed to be done while changing focus of a particular edit text
return;
}
//If a layout container, iterate over children and seed recursion.
if (view instanceof ViewGroup) {
for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
View innerView = ((ViewGroup) view).getChildAt(i);
setupUI(innerView, editable);
}
}
}
Provide this method with your parent view of your fragment or activity.
When you are clicking edit button pass the parent view and true(i.e, editable) to the method and after editing pass parent view and false(i.e, not editable) instead.

From android:descendantFocusability docs:
Defines the relationship between the ViewGroup and its descendants when looking for a View to take focus.
Apply this to the parent of those EditTexts:
android:descendantFocusability="blocksDescendants"
This will result the ViewGroup to block its descendants from receiving focus.

How to disable the default keyboard in EditText, allowing the other actions

I have an EditText, since I use a custom keyboard in my App, I have disabled the standard android keyboard.
Unfortunately now seems that I cannot use the copy paste, selection etc when I click on the EditText in Jelly Bean, in Gingerbread my edit text has the desired behavior.
I need simply to disable the android keyboard to use my custom keyboard but the others copy-paste actions, selection etc, must be active
How could I fix this?
My EditText is this:
<EditText
android:id="#+id/input"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="5dp"
android:autoText="false"
android:background="#color/light_sky"
android:cursorVisible="true"
android:editable="true"
android:gravity="left"
android:imeOptions="flagNoEnterAction|flagNoExtractUi"
android:scrollbars="none"
android:singleLine="true"
android:textSize="32dip" />

You proably have set a null input in your EditText.
If other situations you can prevent the keyboard showing simply using in the manifest
android:configChanges="orientation|keyboardHidden"
In this way the Android keyboard will not auto-open but is shown only if you click directly the EditText

Building on this topic https://stackoverflow.com/a/10636686/2558337 i suppose that you should #Override onClickListener
inputField.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
}
});

You could even try this that works
declare a InputMethodManager variable private InputMethodManager imm;
And in your onActivityCreated() method add these lines
// to hide the keypad
imm = (InputMethodManager) getActivity().getBaseContext().getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(inputSearch.getWindowToken(), 0);
And to unhide use the following code
editText = (EditText) getView().findViewById(R.id.editText);
editText.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
imm.showSoftInput(inputSearch, 0);
}
});

How to invoke onClick and onLongClick of EditText from RelativeLayout

I'm creating a compose screen for my app. I have a ScrollView which contains a RelativeView which in turn contains two things: the EditText where the user types a message, and an ImageView whose visibility is toggled on and off depending on whether an image is attached to the status or not. Here's that part of my layout XML.
<!-- #dimen/bigGap = 8dp -->
<ScrollView android:id="#+id/parentScrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:layout_marginTop="#dimen/bigGap"
android:layout_marginRight="#dimen/bigGap"
android:layout_marginLeft="#dimen/bigGap"
android:layout_marginBottom="#dimen/bigGap"
android:layout_above="#+id/footer"
android:background="#006400"
> <!-- green background color -->
<RelativeLayout android:id="#+id/parentLinearLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#FFD700"> <!-- yellow background color -->
<EditText android:id="#+id/postText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#dddddd"
android:inputType="textMultiLine"
android:gravity="top|left"
/> <!-- gray background color -->
<ImageView android:id="#+id/postImage"
android:layout_width="#dimen/thumbnailSize"
android:layout_height="#dimen/thumbnailSize"
android:visibility="gone"
android:layout_below="#id/postText"
/>
</RelativeLayout>
</ScrollView>
Because my EditText's height is wrap_content, the whole thing starts off with a single line of gray background (the EditText) on top of a yellow background (the RelativeLayout, which fully covers the green background of the ScrollView). However, I'll later change all the views' backgrounds to white (to make them look like a single component) and it will be counter-intuitive for the user to be able to tap only that single line of EditText to make the keyboard pop up.
What I want to do is to redirect the click and long click actions of the RelativeLayout to the click and long click actions of the EditText, but my code below doesn't work. Help?
final EditText editText = (EditText) findViewById(R.id.postText);
RelativeLayout rl = (RelativeLayout) findViewById(R.id.parentLinearLayout);
rl.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Logger.d("onClick invoked!");
editText.performClick();
}
});
rl.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
Logger.d("onLongClick invoked!");
return editText.performLongClick();
}
});
My intention here is so that when the RelativeLayout is clicked, the keyboard pops up (as it does when done to an EditText) and when long-pressed, display the cut/copy/paste/text selection options (same behavior with EditText).

From the description, What you actually want is to open the keyboard. So your title for the question suggests a solution, not the actual problem.
call this from your click listener (or immediately when you show the page):
((InputMethodManager) myActivity
.getSystemService(Context.INPUT_METHOD_SERVICE))
.toggleSoftInput(InputMethodManager.SHOW_FORCED,
InputMethodManager.HIDE_IMPLICIT_ONLY);
Edit:
You must also call editText.requestFocus(); (#Phil is right), but from my experience it's not enough to open the keyboard, so you'll need also the ugly code above.

What you want is for your EditText to gain focus (which in-turn causes the keyboard to show):
rl.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Logger.d("onClick invoked!");
editText.requestFocus();
}
});
rl.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
Logger.d("onLongClick invoked!");
editText.requestFocus();
return true;
}
});

Android: How to propagate click event to LinearLayout childs and change their drawable

I would like to create a linear layout which would behave similarly to ImageButton.
<LinearLayout
android:id="#+id/container"
style="?WidgetHomeIconContainer">
<ImageView
android:id="#+id/icon"
style="?WidgetHomeIcon" />
<TextView
android:id="#+id/title"
style="?WidgetHomeLabel"
android:text="#string/title"
android:textAppearance="?attr/TextHomeLabel" />
</LinearLayout>
In styles of ImageView, TextView and LinearLayout, I set a selectors for all states.
Now:
when I click on ImageView (I tried it also with ImageButton) - it behaves correctly and the image is changed according the selector xml.
when I click on LinearLayout - the linear layout is clicked, but the the ImageView and TextView don't change it's drawable/appearance
So I would like to do the following. When I click on parent LinearLayout, I need to change all it's childs to pressed state.
I tried to add following code to LinearLayout onClickListener to propagate the click:
#Override
public void onClick(View v)
{
LinearLayout l = (LinearLayout) v;
for(int i = 0; i < l.getChildCount(); i++)
{
l.getChildAt(i).setClickable(true);
l.getChildAt(i).performClick();
}
}
But it still reamins the same. Thank you very much for any help.

Put
android:duplicateParentState="true"
in your ImageView and TextView..then the views get its drawable state (focused, pressed, etc.) from its direct parent rather than from itself.

Not only make for every child:
android:duplicateParentState="true"
But also additionally:
android:clickable="false"
This will prevent unexpected behaviour (or solution simply not working) if clickable child views are used.
SO Source

After having the same problem some months later, I found this solution:
private void setOnClickListeners() {
super.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
onClick(v);
}
});
for (int index = 0; index < super.getChildCount(); index++) {
View view = super.getChildAt(index);
view.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
onClick(v);
}
});
}
}
protected void onClick(View v) {
// something to do here...
}

In my case, no one of the other solutions works!
I finally had to use OnTouchListener as explained here, capturing the event when the user clicks in the parent view, and removing all childs OnClickListener.
So the idea is, delegate the click behavior to the parent, and notify the child that is really clicked, if you want to propagate the event. ¡¡That's what we are looking for!!
Then, we need to check which child has been clicked. You can find a reference here to know how it´s done. But the idea is basiclly getting the area of the child, and asking for who contains the clicked coordinates, to perform his action (or not).

At first, my child view failed to get click from parent. After investigating, what I need to do to make it work are:
remove click listener on child view
adding click listener on parent view
So, I don't need to add these on every children.
android:duplicateParentState="true"
android:clickable="false"
I only add duplicateParentState to one of my child view.
My child view is now listening to parent click event.

How to remove focus without setting focus to another control?

I like my UIs to be intuitive; each screen should naturally and unobtrusively guide the user on to the next step in the app. Barring that, I strive to make things as confusing and confounding as possible.
Just kidding :-)
I've got three TableRows, each containing a read-only and non-focusable EditText control and then a button to its right. Each button starts the same activity but with a different argument. The user makes a selection there and the sub-activity finishes, populating the appropriate EditText with the user's selection.
It's the classic cascading values mechanism; each selection narrows the available options for the next selection, etc. Thus I'm disabling both controls on each of the next rows until the EditText on the current row contains a value.
I need to do one of two things, in this order of preference:
When a button is clicked, immediately remove focus without setting focus to a different button
Set focus to the first button when the activity starts
The problem manifests after the sub-activity returns; the button that was clicked retains focus.
Re: #1 above - There doesn't appear to be a removeFocus() method, or something similar
Re: #2 above - I can use requestFocus() to set focus to the button on the next row, and that works after the sub-activity returns, but for some reason it doesn't work in the parent activity's onCreate().
I need UI consistency in either direction--either no buttons have focus after the sub-activity finishes or each button receives focus depending on its place in the logic flow, including the very first (and only) active button prior to any selection.

Using clearFocus() didn't seem to be working for me either as you found (saw in comments to another answer), but what worked for me in the end was adding:
<LinearLayout
android:id="#+id/my_layout"
android:focusable="true"
android:focusableInTouchMode="true" ...>
to my very top level Layout View (a linear layout). To remove focus from all Buttons/EditTexts etc, you can then just do
LinearLayout myLayout = (LinearLayout) activity.findViewById(R.id.my_layout);
myLayout.requestFocus();
Requesting focus did nothing unless I set the view to be focusable.

Old question, but I came across it when I had a similar issue and thought I'd share what I ended up doing.
The view that gained focus was different each time so I used the very generic:
View current = getCurrentFocus();
if (current != null) current.clearFocus();

You can use View.clearFocus().
Use View.requestFocus() called from onResume().

android:descendantFocusability="beforeDescendants"
using the following in the activity with some layout options below seemed to work as desired.
getWindow().getDecorView().findViewById(android.R.id.content).clearFocus();
in connection with the following parameters on the root view.
<?xml
android:focusable="true"
android:focusableInTouchMode="true"
android:descendantFocusability="beforeDescendants" />

About windowSoftInputMode
There's yet another point of contention to be aware of. By default,
Android will automatically assign initial focus to the first EditText
or focusable control in your Activity. It naturally follows that the
InputMethod (typically the soft keyboard) will respond to the focus
event by showing itself. The windowSoftInputMode attribute in
AndroidManifest.xml, when set to stateAlwaysHidden, instructs the
keyboard to ignore this automatically-assigned initial focus.
<activity
android:name=".MyActivity"
android:windowSoftInputMode="stateAlwaysHidden"/>
great reference

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

I use this when already finished update profile info and remove all focus from EditText in my layout
====> Update: In parent layout content my EditText add line:
android:focusableInTouchMode="true"

What about just adding android:windowSoftInputMode="stateHidden" on your activity in the manifest.
Taken from a smart man commenting on this: https://stackoverflow.com/a/2059394/956975

I tried to disable and enable focusability for view and it worked for me (focus was reset):
focusedView.setFocusable(false);
focusedView.setFocusableInTouchMode(false);
focusedView.setFocusable(true);
focusedView.setFocusableInTouchMode(true);

First of all, it will 100% work........
Create onResume() method.
Inside this onResume() find the view which is focusing again and again by findViewById().
Inside this onResume() set requestFocus() to this view.
Inside this onResume() set clearFocus to this view.
Go in xml of same layout and find that top view which you want to be focused and set focusable true and focusableInTuch true.
Inside this onResume() find the above top view by findViewById
Inside this onResume() set requestFocus() to this view at the last.
And now enjoy......

android:focusableInTouchMode="true"
android:focusable="true"
android:clickable="true"
Add them to your ViewGroup that includes your EditTextView.
It works properly to my Constraint Layout. Hope this help

You could try turning off the main Activity's ability to save its state (thus making it forget what control had text and what had focus). You will need to have some other way of remembering what your EditText's have and repopulating them onResume(). Launch your sub-Activities with startActivityForResult() and create an onActivityResult() handler in your main Activity that will update the EditText's correctly. This way you can set the proper button you want focused onResume() at the same time you repopulate the EditText's by using a myButton.post(new Runnable(){ run() { myButton.requestFocus(); } });
The View.post() method is useful for setting focus initially because that runnable will be executed after the window is created and things settle down, allowing the focus mechanism to function properly by that time. Trying to set focus during onCreate/Start/Resume() usually has issues, I've found.
Please note this is pseudo-code and non-tested, but it's a possible direction you could try.

You do not need to clear focus, just add this code where you want to focus
time_statusTV.setFocusable(true);
time_statusTV.requestFocus();
InputMethodManager imm = (InputMethodManager)this.getSystemService(Service.INPUT_METHOD_SERVICE);
imm.showSoftInput( time_statusTV, 0);

Try the following (calling clearAllEditTextFocuses();)
private final boolean clearAllEditTextFocuses() {
View v = getCurrentFocus();
if(v instanceof EditText) {
final FocusedEditTextItems list = new FocusedEditTextItems();
list.addAndClearFocus((EditText) v);
//Focus von allen EditTexten entfernen
boolean repeat = true;
do {
v = getCurrentFocus();
if(v instanceof EditText) {
if(list.containsView(v))
repeat = false;
else list.addAndClearFocus((EditText) v);
} else repeat = false;
} while(repeat);
final boolean result = !(v instanceof EditText);
//Focus wieder setzen
list.reset();
return result;
} else return false;
}
