如何創建動態的底部導航欄或底部欄

Question

我在此活動中創建了一個活動，有一個特定的選項卡，我只想以編程方式創建這些底部欄，以插入類似這樣的數據

gridArray.add(new Item(homeIcon, rs.getString("Name"), OpenIn, rs.getString("Covers"), rs.getString("Count_Checks")));

這是我的TabsActivity，我只想在此活動中添加此底部導航

package abtech.waiteriano.com.waitrer;

import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;

import java.util.ArrayList;
import java.util.List;

import abtech.waiteriano.com.waitrer.fragments.TablesFragment;

public class TabsActivity extends AppCompatActivity {

    private Toolbar toolbar;
    private TabLayout tabLayout;
    private ViewPager viewPager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tabs);
        toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);


        viewPager = (ViewPager) findViewById(R.id.viewpager);

        /**
         * Initializing the viewpager with fragments
         */
        ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());


        adapter.addFragment(new TablesFragment(), "Progress");
        adapter.addFragment(MyFragment.newInstance("Example1"), "Example1");
        adapter.addFragment(MyFragment.newInstance("Example2"), "Example2");
        adapter.addFragment(MyFragment.newInstance("Example3"), "Example3");

        viewPager.setAdapter(adapter);

        tabLayout = (TabLayout) findViewById(R.id.tabs);

        //adding viewpager to the tablayout
        tabLayout.setupWithViewPager(viewPager);
        tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);
    }
    class ViewPagerAdapter extends FragmentPagerAdapter {
        private final List<Fragment> mFragmentList = new ArrayList<>();
        private final List<String> mFragmentTitleList = new ArrayList<>();

        public ViewPagerAdapter(FragmentManager manager) {
            super(manager);
        }

        @Override
        public Fragment getItem(int position) {
            return mFragmentList.get(position);
        }

        @Override
        public int getCount() {
            return mFragmentList.size();
        }

        public void addFragment(Fragment fragment, String title) {
            mFragmentList.add(fragment);
            mFragmentTitleList.add(title);
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return mFragmentTitleList.get(position);
        }
    }
}

您可以使用最近添加的支持庫中提供的官方google BottomNavigationView類。只需在應用程序build.gradle文件中添加以下依賴項

compile ‘com.android.support:design:25.0.0’

您可以在這里找到文檔
