您可以尝试使用单选按钮的自定义可绘制背景作为示例 -

function getItemWithTooltip(item_id, div_id) {
var xmlhttp2 = new XMLHttpRequest();
var url2 = "https://api.guildwars2.com/v2/items/"+item_id;

xmlhttp2.onreadystatechange=function() {if (xmlhttp2.readyState == 4 && xmlhttp2.status == 200) {parseItemTooltip(xmlhttp2.responseText);}};
xmlhttp2.open("GET", url2, true);
//xmlhttp2.send();

var item;

var cache_enabled = true;
// Cache results for quicker page loads
if (cache_enabled == true){
    if (Storage !== void(0)) {
        // Retrieve data (if stored)
        if (sessionStorage[String(item_id)]) {
            //item = JSON.parse(sessionStorage.getItem(String(item_id)));
            item = JSON.parse(sessionStorage[item_id.toString()]);
            //window.alert("sessionStorage: Retrieved");
            //alert(typeof (item));
            //alert(item);
        }
    }
}

if (item == null){
    xmlhttp2.send();
}

  function parseItemTooltip(response) {
    //var item = JSON.parse(response);

    if (item == null){
        // Store data
        if (cache_enabled == true){sessionStorage.setItem(item_id.toString(), JSON.stringify(response));}
        //sessionStorage.setItem(String(item_id), item);
        //if (cache_enabled == true){sessionStorage.setItem(String(item_id), response);}
        //window.alert("sessionStorage: Stored");
        item = JSON.parse(response);
    }
    //..More code here that was not relevant and removed to save space..
  }
}

并在您的drawable中创建您的<RadioButton android:id="@+id/radio0" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/custom_drawable_toggle_background" android:button="@null" android:checked="true" android:text="RadioButton" />

custom_drawable_toggle_background.xml
