Question

我正在建造一些精子,其中载有我从一份文件中总结的信息。因此,我决定使pin子适应一个阵列。如果我开始这样一阵:

String [] TEST = {"one", "two", "three"} and pass this string here:

ArrayAdapter<String> numAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, TEST);

一切产品都进行罚款。 BUT,因为我不一定知道什么会进入主轴,我有一位教长(这名教官正确说话,并储存着阵列中的信息),这造成方案在我把阵列通过阿雷拉Adapter时坠毁。我通过建造一个像样的简便阵列来测试它:

for(int i = 0; i < 6; i++){
        test[i] = {"hi"};
    }

以及DOESN T工作。为什么会这样做?

Answer 1

No curley braces while assigning value, as well as you need to initiate array with size before using it. Here is example code. But this code will populate "hi" 6 times.

String[] test = new String[6];
for(int i = 0; i < 6; i++){
        test[i] = "hi";
    }
