KeyCode_Enter to next edittext
提问by soclose
In edittext, after typing 'Enter' key, system make a new line inside it. I'd like to focus on next edittext, no new line. how to code? my code in xml is below
在edittext 中，输入'Enter' 键后，系统在其中创建一个新行。我想专注于下一个编辑文本，没有新行。如何编码？我在 xml 中的代码如下
<EditText
android:id="@+id/txtNPCode"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="18sp"
android:layout_alignLeft="@+id/lblNPCode"
android:layout_below="@+id/lblNPCode"
android:layout_centerHorizontal="true"/>
<EditText
android:id="@+id/txtCNPCode"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="18sp"
android:layout_alignLeft="@+id/lblCNPCode"
android:layout_below="@+id/lblCNPCode"
android:layout_centerHorizontal="true"/>
I also caputer key code in setOnKeyListener
我还在 setOnKeyListener 中捕获关键代码
tCNPCode.setOnKeyListener(new OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
// TODO Auto-generated method stub
if(keyCode == 66) {
Toast.makeText(S_PCode.this, "Enter Key", Toast.LENGTH_LONG).show();
//tNPCode.setFocusable(true);
}
return false;
}
});

You have to use the requestFocusmethod. In your case it will be something like:
您必须使用该requestFocus方法。在您的情况下，它将类似于：
tCNPCode.setOnKeyListener(new OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
if(keyCode == 66) {
txtCNPCode.requestFocus();
}
return false;
}
});

You don't even have to use OnKeyListener. Simply add line android:singleLine="true"to your EditText. After this operation EditTextbehaves exactly like you want. So, in your particular case:
您甚至不必使用OnKeyListener. 只需将行添加android:singleLine="true"到您的EditText. 此操作后的EditText行为完全符合您的要求。因此，在您的特定情况下：
<EditText
android:id="@+id/txtNPCode"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="18sp"
android:layout_alignLeft="@+id/lblNPCode"
android:layout_below="@+id/lblNPCode"
android:layout_centerHorizontal="true"
android:singleLine="true"
/>
<EditText
android:id="@+id/txtCNPCode"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textSize="18sp"
android:layout_alignLeft="@+id/lblCNPCode"
android:layout_below="@+id/lblCNPCode"
android:layout_centerHorizontal="true"
/>
solves the problem.
解决了这个问题。

The best way is to use one of the options for inputType, for example: android:inputType="textPersonName"This will achieve the wanted effect. Check out the other options too, it'll save you some time in future :)
最好的方法是使用 inputType 的选项之一，例如：android:inputType="textPersonName"这将达到想要的效果。也请查看其他选项，它会在将来为您节省一些时间:)
You shouldn't use android:singleLine="true", since it's deprecated. Here's what the documentations says about it:
您不应该使用 android:singleLine="true"，因为它已被弃用。以下是文档对此的说明：
This attribute is deprecated and is replaced by the textMultiLine flag in the inputType attribute. Use caution when altering existing layouts, as the default value of singeLine is false (multi-line mode), but if you specify any value for inputType, the default is single-line mode. (If both singleLine and inputType attributes are found, the inputType flags will override the value of singleLine.).
此属性已弃用，并由 inputType 属性中的 textMultiLine 标志替换。更改现有布局时要小心，因为 singeLine 的默认值为 false（多行模式），但如果为 inputType 指定任何值，则默认值为单行模式。（如果找到 singleLine 和 inputType 属性，则 inputType 标志将覆盖 singleLine 的值。）。

Consider IME options, good description here http://androidcookbook.com/Recipe.seam;jsessionid=C824437B48F346E23FBE5828969029B4?recipeId=422and documentation here http://developer.android.com/reference/android/widget/TextView.html#attr_android:imeOptions.
考虑 IME 选项，这里有很好的描述http://androidcookbook.com/Recipe.seam;jsessionid=C824437B48F346E23FBE5828969029B4?recipeId=422和文档在这里http://developer.android.com/reference/android/widget/TextViewandroid.html#attr_ :imeOptions。
The only thing you need is add attribute android:imeOptions="actionNext" on each EditText. Keyboard appears with a Next key where Enter used to be and allows to navigate to the next EditText.
您唯一需要的是在每个 EditText 上添加属性 android:imeOptions="actionNext"。键盘与 Next 键一起出现在 Enter 曾经所在的位置，并允许导航到下一个 EditText。
But order of "actionNext" is from top to bottom. For example, if you have horizontal layout:
但是“actionNext”的顺序是从上到下。例如，如果您有水平布局：
<LinearLayout android:orientation="horizontal" >
<EditText android:id="@+id/et1" android:imeOptions="actionNext" />
<EditText android:id="@+id/et2" android:imeOptions="actionNext" />
</LinearLayout>
et2 never get focus. You should fix it in the code:
et2 永远不会得到焦点。您应该在代码中修复它：
et1.setOnEditorActionListener(new OnEditorActionListener()
{
@Override
public boolean onEditorAction(TextView v, int actionId,
KeyEvent event)
{
switch (actionId)
{
case EditorInfo.IME_ACTION_NEXT:
boolean result = false;
TextView v1 = (TextView) v.focusSearch(View.FOCUS_RIGHT);
if (v1 != null)
result = v1.requestFocus(View.FOCUS_RIGHT);
else if (!result)
{
v1 = (TextView) v.focusSearch(View.FOCUS_DOWN);
if (v1 != null)
result = v1.requestFocus(View.FOCUS_DOWN);
}
if (!result)
v.onEditorAction(actionId);
break;
default:
v.onEditorAction(actionId);
break;
}
return true;
}
});

Just set the maximum number of line to the EditTextbox in xml layout file:
android:maxLength="1"
只需将最大行数设置为EditTextxml 布局文件中的框：
android:maxLength="1"

Use Single Line of Code
使用单行代码
tCNPCode.setSingleLine(true);
It will navigate to next item on enter press
按下回车键，它将导航到下一个项目
