我正在使用keyboardview拥有自己的键盘。
工作正常,但我不能像按键盘那样放大按键的效果
这些是使用
的部分<android.inputmethodservice.KeyboardView
android:id="@+id/keyboardview"
style="@style/Widget.KeyboardView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:focusable="true"
android:focusableInTouchMode="true"
android:shadowRadius="0"
android:visibility="visible" />
<style name="Widget.KeyboardView" parent="android:Widget.KeyboardView">
<item name="android:background">@drawable/naranja</item>
<item name="android:keyBackground">@drawable/naranja</item>
<item name="android:keyTextSize">40sp</item>
<item name="android:keyTextColor">#d35400</item>
<item name="android:keyPreviewLayout">@layout/keyboard_popup_keyboard</item>
<item name="android:keyPreviewOffset">12dp</item>
<item name="android:keyPreviewHeight">80dp</item>
<item name="android:popupLayout">@layout/keyboard_popup_keyboard</item>
</style>
XML /弹出:
<?xml version="1.0" encoding="utf-8"?>
<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"
android:keyWidth="10%p"
android:keyHeight="10%p">
</Keyboard>
行
<Key
android:codes="81"
android:keyEdgeFlags="left"
android:keyLabel="Q"
android:popupCharacters="Q"
android:popupKeyboard="@xml/popup" />
etc...
我尝试过使用onKey方法,也来自XML。但没有成功。

仅显示放大的预览,KeyboardView
默认情况下应该这样做。您不希望设置popupKeyboard
值,因为这是针对长按时显示的特殊迷你键盘。
我假设您关注this tutorial。请注意第3.3节中的这些内容:
// Do not show the preview balloons
mKeyboardView.setPreviewEnabled(false);
而是将其设置为true
。
完整解决方案
在您的活动布局中:
<android.inputmethodservice.KeyboardView
android:id="@+id/keyboardview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:focusable="true"
android:focusableInTouchMode="true"
android:keyPreviewOffset="12dp"
android:keyPreviewLayout="@layout/kbpreview"
android:visibility="visible" />
此处的重要属性为keyPreviewLayout
,keyPreviewOffset
和keyPreviewHeight
。
布局/ kbpreview.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:gb="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="10dp"
android:background="@color/red"
android:textSize="30dp" />
XML / kb.xml
<?xml version="1.0" encoding="utf-8"?>
<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"
android:keyWidth="12.50%p"
android:keyHeight="10%p" >
<Row>
<Key android:codes="55" android:keyLabel="7" android:keyEdgeFlags="left" />
<Key android:codes="56" android:keyLabel="8" />
<Key android:codes="57" android:keyLabel="9" />
<Key android:codes="65" android:keyLabel="A" android:horizontalGap="6.25%p" />
<Key android:codes="66" android:keyLabel="B" />
<Key android:codes="55006" android:keyLabel="CLR" android:keyEdgeFlags="right"/>
</Row>
<!-- and whatever else... -->
</Keyboard>
在您的活动代码中
Keyboard mKeyboard = new Keyboard(this, R.xml.kb);
// Lookup the KeyboardView
KeyboardView mKeyboardView = (KeyboardView) findViewById(R.id.keyboardview);
// Attach the keyboard to the view
mKeyboardView.setKeyboard(mKeyboard);
// Key listener required
mKeyboardView.setOnKeyboardActionListener(myListener);
