使用React-Native实现类似Instagram的按钮

Question

我正在尝试在我的React-Native应用程序中实现类似Instagram的按钮，但是我无法做到，我尝试了if-else语句和switch-case， 三元运算符“？”。

if (age < 3) {
  return <View></View>;
} else if (age < 18) {
  return  <View></View>;
} else if (age < 100) {
  return <View></View>;
} else {
  return <View></View>;
}




switch (x) {
  case 'value1': // if (x === 'value1')
       return     <View></View>
  case 'value2': // if (x === 'value2')
    return <View></View>
  default:
   return <View></View>
}



let message = (login == 'Employee') ? 'Hello' :
  (login == 'Director') ? 'Greetings' :
  (login == '') ? 'No login' :
  '';

我使用了上述三种方法，但是我没有得到所需的输出，如果用户单击特定的帖子，我想以绿色显示like按钮，在所有情况下我都希望以白色显示，< / p>

我无法显示按钮的默认状态，而显示默认状态时，我得到了剩余的用户详细信息，
一旦检查了我上面的代码，请告诉我是否做错了什么，如果我做错了什么，请告诉我。

如果有人知道任何其他方法，请告诉我...
