    【解决方案1】:

    你必须创建一个扩展 PopupWindow 的类

    public class CustomPopup extends PopupWindow {
        Context mContext;
        View rootView;
    
        public CustomPopup(View rootView, Context mContext){
            super(mContext);
            this.mContext = mContext;
            this.rootView = rootView;
            View customView = createCustomView();
            setContentView(customView);
            setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
            setSize(250, LayoutParams.MATCH_PARENT);
        }
    
        private View createCustomView(){
            LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View view = inflater.inflate(R.layout.custom_popup, null, false);
    
            return view;
        }
    
        public void setSize(int width, int height){
            setWidth(width);
            setHeight(height);
        }
    
    }
    

    然后在你的软键盘类中使用它

    CustomPopup popupWindow;
    
    public View onCreateInputView() {
            final View root = getLayoutInflater().inflate(R.layout.input, null);
    
            popupWindow = new CustomPopup(root, this);
    
            return root;
    }
    

    这是显示弹出窗口的方法。请注意,mInputView 是您的 keyboardView 变量

    private void showPopup() {
            int height = mInputView.getHeight();
            popupWindow.setSize(LayoutParams.MATCH_PARENT, height);
            popupWindow.showAtLocation(mInputView.getRootView(), Gravity.BOTTOM, 0, 0);
            final InputMethodManager mInputMethodManager = (InputMethodManager) getBaseContext()
                    .getSystemService(Context.INPUT_METHOD_SERVICE);
            mInputMethodManager.showSoftInput(mInputView, 0);
        }
