当我打开我的应用程序时,默认选择Home_Tab打开,工作正常....但在这个Home_Tab,Bottombar也在那里,我不想要关于我们的默认选择标签? 如果我想点击AboutUs_Tab那个时候会打开??? 但在上面的图像中,当我打开Home_Tab,自动选择AboutUs_Tab但没有打开它时,会尝试点击那些关于us_Tab不工作??? 当我点击ContactUS_Tab并返回AboutUs_Tab时,那个时候AboutUS_Tab打开了??如何避免这个问题?
这是我的代码
public class MainActivity extends FragmentActivity {
private Context context;
//This is our tablayout
private TabLayout tabLayout;
BottomBar bottombar;
//This is our viewPager
private ViewPager viewPager;
public ViewPagerAdapter FragmentStatePagerAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//setHasOptionsMenu(true);
bottombar = BottomBar.attach(MainActivity.this, savedInstanceState);
bottombar.noNavBarGoodness();
bottombar.setItemsFromMenu(R.menu.bottom_bar_menu, new OnMenuTabSelectedListener() {
@Override
public void onMenuItemSelected(int itemId) {
switch (itemId) {
case R.id.about_us:
About_Us about_us = new About_Us();
About_Fragment about_fragment = new About_Fragment();
getSupportFragmentManager().beginTransaction().replace(R.id.Home_BottomBar_Fragment, about_fragment).commit();
break;
case R.id.contact_us:
ContactUs_Activity contactUs_activity = new ContactUs_Activity();
Contact_us_Fragment contact_us_fragment = new Contact_us_Fragment();
FragmentManager fm2 = getSupportFragmentManager();
FragmentTransaction ft2 = fm2.beginTransaction();
ft2.replace(R.id.Home_BottomBar_Fragment, contact_us_fragment).commit();
//squareFragment.updateColor(Color.parseColor(colors[1]));
//Toast.makeText(MainActivity.this,"selected contact_us",Toast.LENGTH_SHORT).show();
break;
case R.id.donate_us:
Donate_us_Fragment donate_us_fragment = new Donate_us_Fragment();
getSupportFragmentManager().beginTransaction().replace(R.id.Home_BottomBar_Fragment, donate_us_fragment).commit();
//Toast.makeText(MainActivity.this,"selected donate_us",Toast.LENGTH_SHORT).show();
break;
default:
}
}
});
//Initializing the tablayout
tabLayout = (TabLayout) findViewById(R.id.tabLayout);
//Adding the tabs using addTab() method
tabLayout.addTab(tabLayout.newTab().setText("Home").setIcon(R.drawable.home_selector));
tabLayout.addTab(tabLayout.newTab().setText("News").setIcon(R.drawable.news_selector));

//tabLayout.setupWithViewPager(viewPager);

//Creating our pager adapter

tabLayout.setOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(viewPager) {
@Override
public void onTabSelected(TabLayout.Tab tab) {
if (tab.getPosition() == 0) {
bottombar.show();
//bottombar.getCurrentTabPosition();
} else if (tab.getPosition() == 1) {
bottombar.hide();
} else if (tab.getPosition() == 2) {
bottombar.hide();
} else if (tab.getPosition() == 3) {
bottombar.hide();
}else if (tab.getPosition() == 4){
bottombar.hide();
}
super.onTabSelected(tab);
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
super.onTabUnselected(tab);
//tab.getIcon().setAlpha(127);
}
});
}
@Override
protected void onSaveInstanceState(Bundle outstate) {
super.onSaveInstanceState(outstate);
// Necessary to restore the BottomBar's state, otherwise we would
// lose the current tab on orientation change.
bottombar.onSaveInstanceState(outstate);
}

您可以使用以下方法手动设置底栏中的默认选定选项卡:
bottomBar.setDefaultTabPosition(1);
初始化底栏后使用此功能。

您需要添加一个虚拟隐形项目,以使您的思考工作。为此,再创建一个项目:
<item android:id="@+id/none"
android:title=""/>
您创建商品的位置。然后在您的代码中更改为:
bottombar.setItemsFromMenu(R.menu.bottom_bar_menu, new OnMenuTabSelectedListener() {
@Override
public void onMenuItemSelected(int itemId) {
switch (itemId) {
case R.id.none:
break;
case R.id.about_us:
About_Us about_us = new About_Us();
About_Fragment about_fragment = new About_Fragment();
getSupportFragmentManager().beginTransaction().replace(R.id.Home_BottomBar_Fragment, about_fragment).commit();
break;
case R.id.contact_us:
ContactUs_Activity contactUs_activity = new ContactUs_Activity();
Contact_us_Fragment contact_us_fragment = new Contact_us_Fragment();
FragmentManager fm2 = getSupportFragmentManager();
FragmentTransaction ft2 = fm2.beginTransaction();
ft2.replace(R.id.Home_BottomBar_Fragment, contact_us_fragment).commit();
//squareFragment.updateColor(Color.parseColor(colors[1]));
//Toast.makeText(MainActivity.this,"selected contact_us",Toast.LENGTH_SHORT).show();
break;
case R.id.donate_us:
Donate_us_Fragment donate_us_fragment = new Donate_us_Fragment();
getSupportFragmentManager().beginTransaction().replace(R.id.Home_BottomBar_Fragment, donate_us_fragment).commit();
//Toast.makeText(MainActivity.this,"selected donate_us",Toast.LENGTH_SHORT).show();
break;
default:
}
}
});
