Focus movement is based on an algorithm which finds the nearest neighbor in a given direction. In rare cases, the default algorithm may not match the intended behavior of the developer.
Change default behaviour of directional navigation by using following XML attributes:
android:nextFocusDown="@+id/.."
android:nextFocusLeft="@+id/.."
android:nextFocusRight="@+id/.."
android:nextFocusUp="@+id/.."
Besides directional navigation you can use tab navigation. For this you need to use
android:nextFocusForward="@+id/.."
To get a particular view to take focus, call
view.requestFocus()
To listen to certain changing focus events use a View.OnFocusChangeListener
You can use android:imeOptions
for handling that extra button on your keyboard.
Additional features you can enable in an IME associated with an editor to improve the integration with your application. The constants here correspond to those defined by imeOptions.
The constants of imeOptions includes a variety of actions and flags, see the link above for their values.
Value example
ActionNext :
the action key performs a "next" operation, taking the user to the next field that will accept text.
ActionDone :
the action key performs a "done" operation, typically meaning there is nothing more to input and the IME will be closed.
Code example:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<EditText
android:id="@+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="32dp"
android:layout_marginTop="16dp"
android:imeOptions="actionNext"
android:maxLines="1"
android:ems="10" >
<requestFocus />
</EditText>
<EditText
android:id="@+id/editText2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/editText1"
android:layout_below="@+id/editText1"
android:layout_marginTop="24dp"
android:imeOptions="actionDone"
android:maxLines="1"
android:ems="10" />
</RelativeLayout>
If you want to listen to imeoptions events use a TextView.OnEditorActionListener
.
editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_SEARCH) {
performSearch();
return true;
}
return false;
}
});
android:inputType="text"
should bring the same effect. After hiting next to bring the focus to the next element.
android:nextFocusDown="@+id/.."
use this in addition if you dont want the next view to get the focus
add your editText
android:imeOptions="actionNext"
android:singleLine="true"
add property to activity in manifest
android:windowSoftInputMode="adjustResize|stateHidden"
in layout file ScrollView set as root or parent layout all ui
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.ukuya.marketplace.activity.SignInActivity">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!--your items-->
</ScrollView>
</LinearLayout>
if you do not want every time it adds, create style: add style in values/style.xml
default/style:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="editTextStyle">@style/AppTheme.CustomEditText</item>
</style>
<style name="AppTheme.CustomEditText" parent="android:style/Widget.EditText">
//...
<item name="android:imeOptions">actionNext</item>
<item name="android:singleLine">true</item>
</style>
Use the following line
android:nextFocusDown="@+id/parentedit"
parentedit
is the ID of the next EditText
to be focused.
The above line will also need the following line.
android:inputType="text"
or
android:inputType="number"
