我想重新启动与onResume()方法的activitiy。我想我可以用一个Intent来实现的,但在一个无限循环的结束。
I'd like to restart an activitiy with the onResume() method. I thought i can use an Intent to achieve that, but that ends in an endless loop.
@Override
protected void onResume() {
Intent intent = new Intent(MainActivity.this, MainActivity.class);
MainActivity.this.startActivity(intent);
finish();
super.onResume();
}
有另一种方式重新开始活动?
Is there another way to restart an activity?
我会问你为什么要这么做......但这里要说的是突然出现在我的脑海里的第一件事就是:
I would question why you want to do this... but here is the first thing that popped into my mind:
@Override
protected void onCreate(Bundle savedInstanceState) {
...
Log.v("Example", "onCreate");
getIntent().setAction("Already created");
}
@Override
protected void onResume() {
Log.v("Example", "onResume");
String action = getIntent().getAction();
// Prevent endless loop by adding a unique action, don't restart if action is present
if(action == null || !action.equals("Already created")) {
Log.v("Example", "Force restart");
Intent intent = new Intent(this, Example.class);
startActivity(intent);
finish();
}
// Remove the unique action so the next time onResume is called it will restart
else
getIntent().setAction(null);
super.onResume();
}
您应该已创建
唯一的,这样没有其他的意图可能会意外地有这个动作。
You should make "Already created"
unique so that no other Intent might accidentally has this action.
