您可以使用 AccessTokenTracker。您必须监听对空令牌的更改。表示用户在单击注销时注销
tokenTracker = new AccessTokenTracker() {
@Override
protected void onCurrentAccessTokenChanged(AccessToken oldAccessToken, AccessToken currentAccessToken) {
if (currentAccessToken == null) {
Log.d("FB", "User Logged Out.");
//Do your task here after logout
}
}
};
tokenTracker.startTracking();
您也可以使用自定义按钮注销用户并在那里使用您的方法..
只需隐藏 loginButton 的视图并监听 custom_logout 按钮 onClick
custom_logout.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
LoginManager.getInstance().logOut();
//Do your task
}
});
