在MainActivity這是怎麼了,我因此增加TABS如何檢查TabLayout中的Tab是否已被刪除?
tab1 = tabLayout.newTab().setText("TAB 1");
tabLayout.addTab(tab1);
tab2 = (tabLayout.newTab().setText("TAB 2"));
tabLayout.addTab(tab2);
,從對話框基本上我已經實現了我的程序添加&刪除選項卡,但我的問題是我無法找到一個方法來檢查標籤已被刪除,因此,我的程序運行到錯誤,如果我用這在我的應用程序的標籤已經被以前刪除
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。感謝名單。順便問一下,你知道哪些地方可以瞭解更多信息嗎? – choman
@choman是的,材料指南簽出此網站:[標籤佈局指南](https://material.google.com/components/tabs.html#tabs-specs),瞭解tablayout,參數,功能等:[ TabLayout](https://developer.android.com/reference/android/support/design/widget/TabLayout.html)。你也可以查找代碼路徑指南:[Codepath Tablayout](https://github.com/codepath/android_guides/wiki/Google-Play-Style-Tabs-using-TabLayout) –
非常感謝Yasin。 :) – choman
