Android- 无法从静态字段的资源中获取字符串 - 无法从静态上下文中引用非静态方法 getResources”

Question

我使用 launcherIcons class 在网格视图中传递图像和文本。作为下面的代码，工作正常。但我想将字符串更改为

new LauncherIcon(R.mipmap.ic_launcher,getResources().getString(R.string.hello))

我想从 Resources(R.string.hello) 获取字符串，当执行 getResources 警告时 "Non-static Method getResources cannot be referenced from a static-context"

public class MainActivity extends AppCompatActivity implements AdapterView.OnItemClickListener {
    String Activity="MainActivity";
    Context activity_context=MainActivity.this;
    static final LauncherIcon[] ICONS = {
            new LauncherIcon(R.mipmap.ic_launcher,"Hello"),
            new LauncherIcon(R.mipmap.ic_launcher, "About me"),
            new LauncherIcon(R.mipmap.ic_launcher, "Venky"),
            new LauncherIcon(R.mipmap.ic_launcher, "Noctilien"),
            new LauncherIcon(R.mipmap.ic_launcher, "Metro"),
            new LauncherIcon(R.mipmap.ic_launcher, "RER"),
            new LauncherIcon(R.mipmap.ic_launcher, "Bus"),
            new LauncherIcon(R.mipmap.ic_launcher, "Metro"),
            new LauncherIcon(R.mipmap.ic_launcher, "RER"),
            new LauncherIcon(R.mipmap.ic_launcher, "Bus"),

    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

  //blah blah.............


}

LauncherIcon Class

   static class LauncherIcon {
        final String text;
        final int imgId;
        //final String map;

        public LauncherIcon(int imgId, String text) {
            super();
            this.imgId = imgId;
            this.text = text;
          //  this.map = map;
        }

    }

里面的getResources String怎么用？提前致谢。

我要更改的是删除 LauncherIcon class 中的 static，它可能是这样的：

public class LauncherIcon {
final String text;
final int imgId;
    public LauncherIcon(int imgId, String text) {
        super();
        this.imgId = imgId;
        this.text = text;
    }
}

然后你创建 LauncherIcons 没有 static 的数组，如下所示：

LauncherIcon[] ICONS = {
        new LauncherIcon(R.mipmap.ic_launcher,"Hello"),
        new LauncherIcon(R.mipmap.ic_launcher, "About me"),
        new LauncherIcon(R.mipmap.ic_launcher, "Venky"),
        new LauncherIcon(R.mipmap.ic_launcher, "Noctilien"),
        new LauncherIcon(R.mipmap.ic_launcher, "Metro"),
        new LauncherIcon(R.mipmap.ic_launcher, "RER"),
        new LauncherIcon(R.mipmap.ic_launcher, "Bus"),
        new LauncherIcon(R.mipmap.ic_launcher, "Metro"),
        new LauncherIcon(R.mipmap.ic_launcher, "RER"),
        new LauncherIcon(R.mipmap.ic_launcher, "Bus"),

};

I passed images and text in Grid view with launcherIcons class. As the below codes, works fine. But I want to change the String as :

new LauncherIcon(R.mipmap.ic_launcher,getResources().getString(R.string.hello));

如果您在执行此操作时遇到错误，您可以称其为 doing（第一种方法，如果您将其更改为我的答案应该有效）：

LauncherIcon(R.mipmap.ic_launcher, YOURCONTEXT.getResources().getString(R.string.hello));
