我将字符串数组链接到一个变量，并且我有一个按钮，它将添加索引 1 并将 textView 设置为字符串数组变量 [index]，这样我就可以通过以下方式显示字符串数组中的项目列表一个，但是当我按下按钮时，没有任何反应，ViewPostIme0 和 ViewPostIme 指针 1 继续在我的 logcat 中循环
我尝试了一切
我已经尝试将代码简化到最短，但仍然不起作用
简化代码
int index = 0;
Button btn_message;
btn_message = findViewById(R.id.btn_message);
public void onClick(View v) {
switch (v.getId()) {
case (R.id.btn_message):
//if changes in the same page
index++;
btn_message.setText(String.valueOf(messages[index]));
}
}

预期:消息应该被一一设置在按钮上， 实际:但什么也没发生
最佳答案
原因是因为您错过了为按钮设置监听器。
btn_message.setOnClickListener(this);
关于java - 由于 ViewPostIME，按钮不执行任何操作，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/55664023/
