I have an Activity in Android, with two elements:
EditTextListViewWhen my Activity starts, the EditText immediately has input focus (flashing cursor). I don't want any control to have input focus at startup. I tried:
EditText.setSelected(false);
No luck. How can I convince the EditText to not select itself when the Activity starts?

Excellent answers from Luc and Mark however a good code sample is missing. Adding the tag android:focusableInTouchMode="true" to <LinearLayout> like the following example will fix the problem.
<!-- Dummy item to prevent AutoCompleteTextView from receiving focus -->
<LinearLayout
android:focusable="true"
android:focusableInTouchMode="true"
android:layout_width="0px"
android:layout_height="0px"/>
<!-- :nextFocusUp and :nextFocusLeft have been set to the id of this component
to prevent the dummy from receiving focus again -->
<AutoCompleteTextView android:id="@+id/autotext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:nextFocusUp="@id/autotext"
android:nextFocusLeft="@id/autotext"/>
Try clearFocus() instead of setSelected(false). Every view in Android has both focusability and selectability, and I think that you want to just clear the focus.
The only solution I've found is:
android:focusable="true" and android:focusableInTouchMode="true"And the EditText won't get the focus after starting the activity
Yeah I did the same thing - create a 'dummy' linear layout which gets initial focus. Furthermore, I set the 'next' focus IDs so the user can't focus it any more after scrolling once:
<LinearLayout 'dummy'>
<EditText et>
dummy.setNextFocusDownId(et.getId());
dummy.setNextFocusUpId(et.getId());
et.setNextFocusUpId(et.getId());
a lot of work just to get rid of focus on a view..
Thanks
Is the actual problem that you just don't want it to have focus at all? Or you don't want it to show the virtual keyboard as a result of focusing the EditText? I don't really see an issue with the EditText having focus on start, but it's definitely a problem to have the softInput window open when the user did not explicitly request to focus on the EditText (and open the keyboard as a result).
If it's the problem of the virtual keyboard, see the AndroidManifest.xml <activity> element documentation.
android:windowSoftInputMode="stateHidden" - always hide it when entering the activity.
or android:windowSoftInputMode="stateUnchanged" - don't change it (e.g. don't show it if it isn't already shown, but if it was open when entering the activity, leave it open).
Late, but maybe helpful. Create a dummy EditText at the top of your layout then call myDummyEditText.requestFocus() in onCreate()
<EditText android:id="@+id/dummyEditTextFocus"
android:layout_width="0px"
android:layout_height="0px" />
That seems to behave as I expect. No need to handle configuration changes, etc. I needed this for an Activity with a lengthy TextView (instructions).
If you have another view on your activity like a ListView, you can also do:
ListView.requestFocus();
in your onResume() to grab focus from the editText.
I know this question has been answered but just providing an alternative solution that worked for me :)
using the information provided by other posters, I used the following solution:
in the layout XML
<!-- Dummy item to prevent AutoCompleteTextView from receiving focus -->
<LinearLayout
android:id="@+id/linearLayout_focus"
android:focusable="true"
android:focusableInTouchMode="true"
android:layout_width="0px"
android:layout_height="0px"/>
<!-- AUTOCOMPLETE -->
<AutoCompleteTextView
android:id="@+id/autocomplete"
android:layout_width="200dip"
android:layout_height="wrap_content"
android:layout_marginTop="20dip"
android:inputType="textNoSuggestions|textVisiblePassword"/>
in onCreate()
private AutoCompleteTextView mAutoCompleteTextView;
private LinearLayout mLinearLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mylayout);
//get references to UI components
mAutoCompleteTextView = (AutoCompleteTextView) findViewById(R.id.autocomplete);
mLinearLayout = (LinearLayout) findViewById(R.id.linearLayout_focus);
}
and finally, in onResume()
@Override
protected void onResume() {
super.onResume();
//do not give the editbox focus automatically when activity starts
mAutoCompleteTextView.clearFocus();
mLinearLayout.requestFocus();
}
Try this before your first editable field:
<TextView
android:id="@+id/dummyfocus"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/foo"
/>
----
findViewById(R.id.dummyfocus).setFocusableInTouchMode(true);
findViewById(R.id.dummyfocus).requestFocus();
You can just set "focusable" and "focusable in touch mode" to value true on the first TextView of the layout. In this way when the activity starts the TextView will be focused but , due to its nature, you will see nothing focused on the screen and ,of course, there will be no keyboard displayed...
None of this solutions worked for me. The way I fix the autofocus was:
<activity android:name=".android.InviteFriendsActivity" android:windowSoftInputMode="adjustPan">
<intent-filter >
</intent-filter>
</activity>
<TextView
android:id="@+id/TextView01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:singleLine="true"
android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"
android:focusable="true"
android:focusableInTouchMode="true"
style="@android:style/Widget.EditText"/>
The problem seems to come from a property that I can only see in the XML form of the layout.
Make sure to remove this line at the end of the declaration within the EditText XML tags:
<requestFocus />
That should give something like that :
<EditText
android:id="@+id/emailField"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="textEmailAddress">
//<requestFocus /> /* <-- without this line */
</EditText>
The following will stop edittext from taking focus when created, but grab it when you touch them.
<EditText
android:id="@+id/et_bonus_custom"
android:focusable="false" />
So you set focusable to false in the xml, but the key is in the java, which you add the following listener:
etBonus.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
v.setFocusable(true);
v.setFocusableInTouchMode(true);
return false;
}
});
Because you are returning false, i.e. not consuming the event, the focusing behavior will proceed like normal.
I needed to clear focus from all fields programmatically. I just added the following two statements to my main layout definition.
myLayout.setDescendantFocusability(ViewGroup.FOCUS_BEFORE_DESCENDANTS);
myLayout.setFocusableInTouchMode(true);
That's it. Fixed my problem instantly. Thanks, Silver, for pointing me in the right direction.
I had tried several answers individually but the focus is still at the EditText. I only managed to solve it by using two of the below solution together.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mainLayout"
android:descendantFocusability="beforeDescendants"
android:focusableInTouchMode="true" >
( Reference from Silver https://stackoverflow.com/a/8639921/15695 )
and remove
<requestFocus />
at EditText
( Reference from floydaddict https://stackoverflow.com/a/9681809 )
The simplest thing I did is to set focus on another view in onCreate:
myView.setFocusableInTouchMode(true);
myView.requestFocus();
This stopped the soft keyboard coming up and there was no cursor flashing in the EditText.
Being that I don't like to pollute the XML with something that is related to functionality, I created this method that "transparently" steals the focus from the first focusable view and then makes sure to remove itself when necessary!
public static View preventInitialFocus(final Activity activity)
{
final ViewGroup content = (ViewGroup)activity.findViewById(android.R.id.content);
final View root = content.getChildAt(0);
if (root == null) return null;
final View focusDummy = new View(activity);
final View.OnFocusChangeListener onFocusChangeListener = new View.OnFocusChangeListener()
{
@Override
public void onFocusChange(View view, boolean b)
{
view.setOnFocusChangeListener(null);
content.removeView(focusDummy);
}
};
focusDummy.setFocusable(true);
focusDummy.setFocusableInTouchMode(true);
content.addView(focusDummy, 0, new LinearLayout.LayoutParams(0, 0));
if (root instanceof ViewGroup)
{
final ViewGroup _root = (ViewGroup)root;
for (int i = 1, children = _root.getChildCount(); i < children; i++)
{
final View child = _root.getChildAt(i);
if (child.isFocusable() || child.isFocusableInTouchMode())
{
child.setOnFocusChangeListener(onFocusChangeListener);
break;
}
}
}
else if (root.isFocusable() || root.isFocusableInTouchMode())
root.setOnFocusChangeListener(onFocusChangeListener);
return focusDummy;
}
At onCreate of your Activity, just add use clearFocus() on your EditText element. For example,
edittext = (EditText) findViewById(R.id.edittext);
edittext.clearFocus();
And if you want to divert the focus to another element, use requestFocus() on that. For example,
button = (Button) findViewById(R.id.button);
button.requestFocus();
Simple solution: In AndroidManifest in Activity tag use
android:windowSoftInputMode="stateAlwaysHidden"
The following worked for me in Manifest. Write ,
<activity
android:name=".MyActivity"
android:windowSoftInputMode="stateAlwaysHidden"/>
For me, what worked on all devices is this:
<!-- fake first focusable view, to allow stealing the focus to itself when clearing the focus from others -->
<View
android:layout_width="0px"
android:layout_height="0px"
android:focusable="true"
android:focusableInTouchMode="true" />
Just put this as a view before the problematic focused view, and that's it.
This is the perfect and most easiest solution.I always use this in my app.
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
You can achieve this by creating a dummy EditText with layout width and height set to 0dp, and request focus to that view. Add the following code snippet in your xml layout:
<EditText
android:id="@+id/editText0"
android:layout_width="0dp"
android:layout_height="0dp"
android:hint="@string/dummy"
android:ems="10"
>
<requestFocus />
</EditText>
Add android:windowSoftInputMode="stateAlwaysHidden" in the activity tag of the Manifest.xml file.
Add following in onCreate method:
this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
Write this code inside Manifest file in the Activity where you do not want to open the keyboard.
android:windowSoftInputMode="stateHidden"
Manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.projectt"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="24" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".Splash"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".Login"
**android:windowSoftInputMode="stateHidden"**
android:label="@string/app_name" >
</activity>
</application>
</manifest>
Write this line in your Parent Layout...
android:focusableInTouchMode="true"
Simplest answer, just add this in parent layout of the XML.
android:focusable="true"
android:focusableInTouchMode="true"
