<1>在MainActivity中编写如下代码:
protected void onSaveInstanceState(Bundle outState){
super.onSaveInstanceState(outState);
String str=“Someing any String Char”;
outState.putString(“Key”,str);
}
在onCreate方法中添加:
if(savedInstanceState!=null){
//得到它
String str1=savedInstanceState.getString(“Key”);
}
ANDROID----使用onSaveInstanceState保存数据
