java - getResources() 抛出错误

Question

我有以下代码，用于在我的应用程序中创建带有两个选项卡的自定义 ListView:

package com.test.testing;

import android.content.Context;
import android.text.Html;

public class SetRows {
    int image;
    String name;
    String id;

    public int getImage () {
        return image;
    }

    public void setImage (int image) {
        this.image = image;
    }

    public String getName () {
        return name;
    }

    public void setName (String name) {
        this.name = name;
    }

    public String getID () {
        return id;
    }

    public void setID (String id) {
        this.id = id;
    }

    public SetRows(int image, String name, String id) {

        super();
        this.image = image;
        this.name = Html.fromHtml(getResources().getString(R.string.colorcol)) + " COLOR: \n\t" + name;
        this.id = "MEANS: \n\t" +  id;
    }

}

以下行:

this.name = Html.fromHtml(getResources().getString(R.string.colorcol)) + "COLOR:\n\t"+ name;

给我以下错误:

SetRows 类型的 getResources() 方法未定义

Answer 1

您需要更改代码，以便获得对当前上下文的引用，从而使您能够访问 getResources。

例如

public SetRows(Context currentContext,int image, String name, String id) {

        super();

        this.image = image;
        this.name = Html.fromHtml(currentContext.getResources().getString(R.string.colorcol)) + " COLOR: \n\t" + name;
        this.id = "MEANS: \n\t" +  id;
    }

您必须将类的实例化更改为

contents.add(new SetRows(this,inIconShow, sColor, sExplain));
