如何同时使用onSaveInstanceState(捆绑包outState)和onSaveInstanceState(捆绑包savedInstanceState)？
提问于 2018-03-05 18:12:41
我正在尝试保存onSaveInstanceState(捆绑包savedInstanceState)的计时器的显示时间。但是，在我的代码中已经有了一个onSaveInstanceState(捆绑包outState)，所以我看到了“onSaveInstanceState(捆绑包)已经在作用域中定义”的警告。
如何同时使用捆绑包savedInstanceState和捆绑包州外？
下面是onSaveInstanceState方法：
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt("CLICK_NUMBER", clickNumber);
outState.putBoolean(BUTTON2CORRECT_CHECKED_KEY, answer2.isChecked());
outState.putBoolean(BUTTON21_CHECKED_KEY, wrongAnswer21.isChecked());
outState.putBoolean(BUTTON22_CHECKED_KEY, wrongAnswer22.isChecked());
outState.putBoolean(BUTTON23_CHECKED_KEY, wrongAnswer23.isChecked());
outState.putBoolean(BUTTON3CORRECT_CHECKED_KEY, answer3.isChecked());
outState.putBoolean(BUTTON31_CHECKED_KEY, wrongAnswer31.isChecked());
outState.putBoolean(BUTTON32_CHECKED_KEY, wrongAnswer32.isChecked());
outState.putBoolean(BUTTON33_CHECKED_KEY, wrongAnswer33.isChecked());
outState.putBoolean(CHECKBOX41_CHECKED_KEY, answer41.isChecked());
outState.putBoolean(CHECKBOX42_CHECKED_KEY, answer42.isChecked());
outState.putBoolean(CHECKBOX43_CHECKED_KEY, answer43.isChecked());
outState.putBoolean(CHECKBOX44_CHECKED_KEY, answer44.isChecked());
outState.putBoolean(CHECKBOX45_CHECKED_KEY, answer45.isChecked());
outState.putBoolean(BUTTON5CORRECT_CHECKED_KEY, answer5.isChecked());
outState.putBoolean(BUTTON51_CHECKED_KEY, wrongAnswer51.isChecked());
outState.putBoolean(BUTTON_CLICKED_KEY, buttonIsClicked);
answer2.setTextColor(0xAA76FF03);
answer3.setTextColor(0xAA76FF03);
answer5.setTextColor(0xAA76FF03);
answer41.setTextColor(0xAA76FF03);
answer42.setTextColor(0xAA76FF03);
answer43.setTextColor(0xAA76FF03);
}
@Override
protected void onSaveInstanceState(Bundle savedInstanceState) {
super.onSaveInstanceState(savedInstanceState);
savedInstanceState.putString("myVar", myVar);
}下面是onCreate方法：
protected void onCreate(Bundle savedInstanceState) { // TODO
Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.html_new_page);
chronometer = findViewById(R.id.chronometer);
chronometer.start();
myVar = chronometer.getText().toString();
if (savedInstanceState == null) {
myVar = chronometer.getText().toString();
} else {
myVar = savedInstanceState.getString("myVar");

它们实际上是一回事！名称只是一个虚拟变量，您可以很容易地更改它，没有任何问题。你的代码可以是：
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt("CLICK_NUMBER", clickNumber);
...
answer43.setTextColor(0xAA76FF03);
// new code here
outState.putString("myVar", myVar);
}或者您可以使用
protected void onSaveInstanceState(Bundle savedInstanceState) {
super.onSaveInstanceState(outState);
savedInstanceState.putInt("CLICK_NUMBER", clickNumber);
...
answer43.setTextColor(0xAA76FF03);
// new code here
savedInstanceState.putString("myVar", myVar);
}只要您更改参数中的名称，它将是相同的。
