软键盘的 POPUP 布局 [英] Soft keyboard's POPUP layout
问题描述
我正在开发一个软键盘并且做得很好，但是我不知道如何为长按键自定义弹出布局.
I'm developing a soft keyboard and doing well, but I don't know how to customize the popup layout for a long keypress.
<?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"
/>
我的键盘布局:
<?xml version="1.0" encoding="utf-8"?>
<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"

我尝试将 keyBackground 和 background 属性 放在任何地方，但没有成功.我试着说:
I tried putting keyBackground and background properties everywhere, but not successfully. I tried to put:
android:popupLayout="@layout/keyboard"
...在 keyboardView 上但得到空指针，也许我在该参数中输入了错误的 XML?
...On the keyboardView but get nullpointer, maybe I'm putting a wrong XML in that parameter?
在我放在这里的键盘弹出 XML中:
In the keyboard popup XML that I put here:
android:popupKeyboard="@xml/keyboard_popup"
我可以更改布局的大小、键大小、键间距和其他内容，但不能更改颜色或背景.
I can change the layout's size, key size, key gap, and other things, but can't change the colors or backgrounds.
key preview也不错，我把这个放在keyboardView上:
The key preview also is doing well, I put this on the keyboardView:
android:keyPreviewLayout="@layout/preview"
...它的工作原理.我认为弹出窗口应该是相同的方式，但事实并非如此.
...And it works. I think the popup should be the same way, but it's not.
推荐答案
嗯，这不是我想要的，但这解决了问题.
Well, it is not exactly what I was looking for, but this resolves the problem.
我制作了自己的键盘视图，并制作了一个弹出窗口来显示何时长按某个键.
I made my own keyboard view and made a popup window to show when a key is long pressed.
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);
return true;
}
}
这样您就可以在 xml 中以任何您想要的方式自定义弹出窗口.
This way you can customize the popup any way you want in the xml.
但这不是正确的答案，如果您知道更好的方法，请回答这个问题.
But this is not the correct answer, if you know a better way to do this please answer this question.
