此处不允许使用数组初始值设定项 [英] Array initializer is not allowed here

问题描述

我正在处理 Android 项目，但遇到一个我无法理解的错误:

I am working on Android project and I am getting an error which I cannot understand:

此处不允许使用数组初始化器

Array initializer is not allowed here

我试图简化我的代码，归结为这个

I tried to simplify my code and it comes down to this

public class MainActivity extends Activity{

    int pos = {0, 1, 2};

    @Override
    protected void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        pos = {2, 1, 0};
    }
}

这里发生了什么?

推荐答案

你应该使用

pos = new int[]{1,2,3};

您只能在变量初始化时使用缩写语法int[] pos = {0,1,2};.

You can only use the abbreviated syntax int[] pos = {0,1,2}; at variable initialization time.

private int[] values1 = new int[]{1,2,3,4};
private int[] values2 = {1,2,3,4}; // short form is allowed only at variable initialization
