android – 軟鍵盤的POPUP佈局

我正在開發一個軟鍵盤,做得很好,但是我不知道如何自定義一個長按鍵的彈出視窗.

我的鍵盤檢視：

<?xml version="1.0" encoding="UTF-8"?>
<android.inputmethodservice.KeyboardView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/keyboard"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:keyPreviewLayout="@layout/preview"
android:keyBackground="@drawable/key_selector"
android:shadowRadius="0.0"
android:keyTextColor="#000000"
/>

我的鍵盤佈局：

<?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">

<Row android:verticalGap="1%p"android:horizontalGap="0.5%p" android:keyHeight="8%p" android:keyWidth="9.6%p">

<Row android:verticalGap="1%p"android:horizontalGap="0.5%p" android:keyHeight="8%p" android:keyWidth="9.6%p">

<Key android:codes="-3"android:keyIcon="@drawable/keyboard_go" 
android:keyHeight="7.6%p" android:keyWidth="18.5%p" android:horizontalGap="1%p"/>
</Row>

鍵盤彈出XML：

<?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>

我嘗試將keyBackground和背景屬性放在任何地方,但不成功.我試圖把：

android:popupLayout="@layout/keyboard"

…在keyboardView上得到nullpointer,也許我在該引數中輸入了錯誤的XML？

在我放在這裡的鍵盤彈出式XML中：

android:popupKeyboard="@xml/keyboard_popup"

我可以改變佈局的大小,按鍵大小,鍵間距等等,但不能改變顏色或背景.

關鍵預覽也做得很好,我把它放在keyboardView上：

android:keyPreviewLayout="@layout/preview"

…它的工作原理我認為彈出視窗應該是一樣的,但不是這樣.

如何自定義出現長按鍵的彈出式視窗？

那麼這不是我正在尋找的,而是解決了這個問題.

我自己建立了鍵盤檢視,並彈出一個彈出視窗來顯示一個鍵長時間按下.

public class MyKeyboardView extends KeyboardView{
@Override
protected boolean onLongPress(final Key popupKey) {
final View custom = LayoutInflater.from(context)
.inflate(R.layout.popup_layout, new FrameLayout(context));
popup = new PopupWindow(context);
popup.setWidth(WindowManager.LayoutParams.WRAP_CONTENT);
popup.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
popup.showAtLocation(this, Gravity.NO_GRAVITY, popupKey.x, popupKey.y-50);
}
}

這樣,您可以在xml中以任何方式自定義彈出視窗.

但是這不是正確的答案,如果你知道一個更好的方法來回答這個問題.
