这里是我的应用程序是如何布局:onActivityResult()之前调用onResume()?
- 的onResume()提示用户登录
- 如果在用户登录时,如果用户在任何注销,他可以继续使用应用程式 3时间,我想再次提示登录
我该如何做到这一点?
这里是我的MainActivity:
@Override
protected void onResume(){
super.onResume();
isLoggedIn = prefs.getBoolean("isLoggedIn", false);
if(!isLoggedIn){
showLoginActivity();
}
}
这里是我的LoginActivity:
@Override
protected void onPostExecute(JSONObject json) {
String authorized = "200";
String unauthorized = "401";
String notfound = "404";
String status = new String();
try {
// Get the messages array
JSONObject response = json.getJSONObject("response");
status = response.getString("status");
if(status.equals(authorized)){
Toast.makeText(getApplicationContext(), "You have been logged into the app!",Toast.LENGTH_SHORT).show();
prefs.edit().putBoolean("isLoggedIn",true);
setResult(RESULT_OK, getIntent());
finish();
}
else if (status.equals(unauthorized)){
Toast.makeText(getApplicationContext(), "The username and password you provided are incorrect!",Toast.LENGTH_SHORT).show();
prefs.edit().putBoolean("isLoggedIn",true);
}
else if(status.equals(notfound)){
Toast.makeText(getApplicationContext(), "Not found",Toast.LENGTH_SHORT).show();
prefs.edit().putBoolean("isLoggedIn",true);
}
} catch (JSONException e) {
System.out.println(e);
} catch (NullPointerException e) {
System.out.println(e);
}
}
}
用户在成功登录后:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
Toast.makeText(getApplicationContext(), "BOOM SHAKA LAKA!",Toast.LENGTH_SHORT).show();
}
}
的问题是,的onResume()在onActivityResult()之前被调用,所以当用户成功登录时,我的主要活动不会得到noti因为onResume()首先被调用。
哪里是最好的地方提示登录?
我在用户登录后设置isLoggedIn。查看我更新的代码。不知道什么是错的? – 2010-11-23 06:18:02
