在MainActivity这是怎么了,我因此增加TABS如何检查TabLayout中的Tab是否已被删除?
tab1 = tabLayout.newTab().setText("TAB 1");
tabLayout.addTab(tab1);
tab2 = (tabLayout.newTab().setText("TAB 2"));
tabLayout.addTab(tab2);
,从对话框基本上我已经实现了我的程序添加&删除选项卡,但我的问题是我无法找到一个方法来检查标签已被删除,因此,我的程序运行到错误,如果我用这在我的应用程序的标签已经被以前删除
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode != RESULT_OK || data == null)
return;
settingList = (ArrayList <SettingCheckBox>) data.getSerializableExtra(SETTING_CHECK_BOX);
for (int i = 0; i < settingList.size(); i++) {
if (settingList.get(i).getChecked()) {
Log.d("**Checked Item**", String.valueOf(settingList.get(i).getDescription()));
//gets the description of the tab that is to be removed
String removeTab = String.valueOf(settingList.get(i).getDescription());
//gets the value of the check box
Boolean checkedValue = settingList.get(i).getChecked();
if (removeTab.equals("TAB 1")) {
//How to check if Tab is already removed ?
if (checkedvalue)
if (tabLayout.equals(tab1)) {
tabLayout.removeTab(tab1);
//basically removes fragment associated with the tab
pagerAdapter.removeTab(0, tab1);
}
}
} else if (removeTab.equals("TAB 2")) {
if (checkedValue) {
tabLayout.removeTab(tab2);
pagerAdapter.removeTab(1, tab2);
}
}
}
是的工作。感谢名单。顺便问一下,你知道哪些地方可以了解更多信息吗? – choman
@choman是的,材料指南签出此网站:[标签布局指南](https://material.google.com/components/tabs.html#tabs-specs),了解tablayout,参数,功能等:[ TabLayout](https://developer.android.com/reference/android/support/design/widget/TabLayout.html)。你也可以查找代码路径指南:[Codepath Tablayout](https://github.com/codepath/android_guides/wiki/Google-Play-Style-Tabs-using-TabLayout) –
非常感谢Yasin。 :) – choman
