我正在开发一个软键盘,做得很好,但是我不知道如何自定义一个长按键的弹出窗口.
我的键盘视图：

<?xml version="1.0" encoding="UTF-8"?><android.inputmethodservice.KeyboardViewxmlns: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"/> |

键盘弹出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> |
我尝试将keyBackground和背景属性放在任何地方,但不成功.我试图把：
|
1
|
android:popupLayout="@layout/keyboard" |
…在keyboardView上得到nullpointer,也许我在该参数中输入了错误的XML？
在我放在这里的键盘弹出式XML中：
|
1
|
android:popupKeyboard="@xml/keyboard_popup" |
我可以改变布局的大小,按键大小,键间距等等,但不能改变颜色或背景.
关键预览也做得很好,我把它放在keyboardView上：
|
1
|
android:keyPreviewLayout="@layout/preview" |
…它的工作原理我认为弹出窗口应该是一样的,但不是这样.
如何自定义出现长按键的弹出式窗口？
那么这不是我正在寻找的,而是解决了这个问题.
我自己创建了键盘视图,并弹出一个弹出窗口来显示一个键长时间按下.

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); }} |
这样,您可以在xml中以任何方式自定义弹出窗口.
但是这不是正确的答案,如果你知道一个更好的方法来回答这个问题.
