Move to another EditText when Soft Keyboard Next is clicked on Android

When I press the 'Next', the focus on the User EditText must be move to the Password. Then, from Password, it must move to the right and so on. Can you help me on how to code it?

enter image description here

<LinearLayout
    android:id="@+id/LinearLayout01"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >

    <TextView
        android:id="@+id/username"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="User Name*" />

    <EditText
        android:id="@+id/txt_User"
        android:layout_width="290dp"
        android:layout_height="33dp"
        android:singleLine="true" />

</LinearLayout>


<LinearLayout
    android:id="@+id/LinearLayout02"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >

    <TextView
        android:id="@+id/password"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Password*" />

    <EditText
        android:id="@+id/txt_Password"
        android:layout_width="290dp"
        android:layout_height="33dp"
        android:singleLine="true"
        android:password="true" />

    <TextView
        android:id="@+id/confirm"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Password*" />

    <EditText
        android:id="@+id/txt_Confirm"
        android:layout_width="290dp"
        android:layout_height="33dp"
        android:singleLine="true"
        android:password="true" />

</LinearLayout>

Focus Handling

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


Keyboard button

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;
    }
});
