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，我有 popupKeyboard 和 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，当上的0键弹出与）节目，余长preSS但它在那里等待直到我preSS的X按钮或）的字符。它看起来像这样：

推荐答案

您可以使用 PopupWindow 类以及自定义布局填充它。

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);

和长preSS

//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);
}

在单击，在弹出的可以关闭它

On click in the popup you can dismiss it

popup.dismiss();
