长按Android自定义键盘弹出键盘

问题描述

我有自定义 Android 键盘:

I have custom Android keyboard:

    public class CustomKeyboard extends Keyboard{...}  

    public class CustomKeyboardView extends KeyboardView{...}

    public class CustomKeyboardIME extends InputMethodService implements KeyboardView.OnKeyboardActionListener{...}  

在某些键上，我有 popupKeyboard 和 popupCharacters:

On some keys, I have popupKeyboard and popupCharacters:

<Key android:codes="144" android:keyLabel="0" android:popupKeyboard="@xml/key_popup" android:popupCharacters=")" android:keyEdgeFlags="right"/>

xml/key_popup.xml:

xml/key_popup.xml:

<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"
      android:keyWidth="10%p"
      android:horizontalGap="0px"
      android:verticalGap="0px"
      android:keyHeight="@dimen/key_height" >
</Keyboard>

但是当我长按0"键弹出)"显示，但它一直在那里，直到我按下X"按钮或)"字符.它看起来像这样:

But when I longPress on "0" key popup with ")" shows, but it stays there until I press "X" button or ")" character. It looks like this:

而且我希望它仅在我握着手指时打开.三星或 HTC 键盘之类的东西:

And I want it to be opened only while I am holding a finger on. Something like on Samsung or HTC keyboard:

有人可以帮帮我吗?

编辑至少可以改变这个弹出窗口的外观吗?我希望它具有与我制作的整个键盘相同的背景和键/

EDIT Is it at least possible to change the appearance of this popup? I want it to have same background and keys as whole keyboard I have made/

推荐答案

您可以使用 PopupWindow 类并使用自定义布局填充它.

You can use PopupWindow class and populate it with custom layout.

View custom = LayoutInflater.from(context)
    .inflate(R.layout.your_layout, new FrameLayout(context));
PopupWindow popup = new PopupWindow(context);
popup.setContentView(custom);

长按

//Get x,y based on the touch position
//Get width, height based on your layout
if(popup.isShowing()){
    popup.update(x, y, width, height);
} else {
    popup.setWidth(width);
    popup.setHeight(height);
    popup.showAtLocation(yourKeyboardView, Gravity.NO_GRAVITY, x, y);
}

点击弹窗即可关闭

popup.dismiss();
