页面上的TextInput输入框在页面底部，点击输入框弹起键盘，如何让输入框自动上移到键盘上方，避免被遮挡？

windowStage.getMainWindow((err, data) => {  
  if (err.code) {  
    console.error('Failed to obtain the main window. Cause: ' + JSON.stringify(err));  
    return;  
  }  
  // let windowClass = null;  
  let windowClass = data;  
  //1. 设置监听键盘变化,用来设置inputview 避让输入法  
  try {  
    windowClass.on('keyboardHeightChange', (data) => {  
      console.info('keyboardHeightChange. Data: ' + JSON.stringify(data));  
      AppStorage.setOrCreate('keyboardHeight', data);  
      console.info(AppStorage.get('keyboardHeight'))  
    });  
  } catch (exception) {  
    console.error('Failed to enable the listener for keyboard height changes. Cause: ' + JSON.stringify(exception));  
  }  
})
