java - 按下按钮时状态不会改变

Question

每当我按下按钮时，它应该更改文本，并且还更改 boolean 值，但这不起作用。有什么帮助吗？谢谢

onCreate 之前:

public boolean status = false;

按钮点击:

case R.id.saveButton:   

if (status != true) {
    currentStatus.setText("Current status: In need of help!");
    status = true;
}
if (status != false) {
    currentStatus.setText("Current status: Fine.");
    status = false;
}
break;

Answer 1

if(status){
       currentStatus.setText("Current status: Fine.");
       status = false;
}else {                             
       currentStatus.setText("Current status: In need of help!");
       status = true
}

或使用三元运算符:

currentStatus.setText(status ? "Current status: Fine." : "Current status: In need of help!");
status = !status;//toggle boolean value
