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?

<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*" />

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

</LinearLayout>


<LinearLayout

推荐答案

焦点处理

焦点移动基于找到最近的算法给定方向的邻居.在极少数情况下，默认算法可能与开发人员的预期行为不匹配.

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.

使用以下 XML 属性更改定向导航的默认行为:

Change default behaviour of directional navigation by using following XML attributes:

android:nextFocusDown="@+id/.."  
android:nextFocusLeft="@+id/.."    
android:nextFocusRight="@+id/.."    
android:nextFocusUp="@+id/.."  

除了定向导航，您还可以使用标签导航.为此，您需要使用

Besides directional navigation you can use tab navigation. For this you need to use

android:nextFocusForward="@+id/.."

要获得特定视图的焦点，请调用

To get a particular view to take focus, call

view.requestFocus()

要监听某些变化的焦点事件，请使用 View.OnFocusChangeListener

To listen to certain changing focus events use a View.OnFocusChangeListener

您可以使用 android:imeOptions 用于处理键盘上的额外按钮.

You can use android:imeOptions for handling that extra button on your keyboard.

您可以在与编辑器关联的 IME 中启用的其他功能改进与您的应用程序的集成.这里的常数对应于 imeOptions 定义的那些.

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.

imeOptions 的常量包括各种动作和标志，请参阅上面的链接了解它们的值.

The constants of imeOptions includes a variety of actions and flags, see the link above for their values.

值示例

ActionNext:

操作键执行下一步"操作，将用户带到下一个接受文本的字段.

the action key performs a "next" operation, taking the user to the next field that will accept text.

ActionDone:

操作键执行完成"操作，通常意味着无需输入任何内容，IME 将关闭.

the action key performs a "done" operation, typically meaning there is nothing more to input and the IME will be closed.

代码示例:

<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>

如果您想收听 imeoptions 事件，请使用 TextView.OnEditorActionListener.

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;
    }
});
