HarmonyOS 输入法的高度是如何确定的？

let dis = display.getDefaultDisplaySync();  
   let dWidth = dis.width;  
   let dHeight = dis.height;  
   let keyHeightRate = 0.47;  
   let keyHeight = dHeight * keyHeightRate;  
   let nonBarPosition = dHeight - keyHeight;  
   let panelInfo: inputMethodEngine.PanelInfo = {  
     type: inputMethodEngine.PanelType.SOFT_KEYBOARD,  
     flag: inputMethodEngine.PanelFlag.FLG_FIXED  
   };  
   inputMethodAbility.createPanel(this.mContext, panelInfo).then(async (inputPanel: inputMethodEngine.Panel) => {  
     this.panel = inputPanel;  
     if (this.panel) {  
       await this.panel.resize(dWidth, keyHeight);  
       await this.panel.moveTo(0, nonBarPosition);  
       await this.panel.setUiContent('InputMethodExtensionAbility/pages/Index');  
     }  
   });
