主 ViewPager Xml佈局 注意引用的是android.support.v4.widget.DrawerLayout
<?xml version="1.0" encoding="utf-8"?> <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/der" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <android.support.design.widget.TabLayout android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" android:id="@+id/tab" ></android.support.design.widget.TabLayout> <android.support.v4.view.ViewPager android:id="@+id/pager" android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="9" ></android.support.v4.view.ViewPager> </LinearLayout> <fragment android:id="@+id/frag" class="fengxiangbin.bwei.com.zhoukao3lian.fragment.Che" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_gravity="start" /> </android.support.v4.widget.DrawerLayout>
TabLayout+Viewpager+側拉
public class MainActivity extends AppCompatActivity { TabLayout tab;//一定要給側拉附ID ViewPager pager; private DrawerLayout drawerLayout; private ActionBarDrawerToggle toggle; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); tab = findViewById(R.id.tab); pager = findViewById(R.id.pager); drawerLayout = findViewById(R.id.der); init(); initAction(); } private void initAction() { //獲取一個ActionBar物件 android.support.v7.app.ActionBar actionBar = getSupportActionBar(); //給左上角一張圖片,4.0意思預設圖片,給true就可以直接使用 actionBar.setDisplayHomeAsUpEnabled(true); //有一類提供了繫結DrawerLayout功能 toggle = new ActionBarDrawerToggle(this, drawerLayout, R.string.open, R.string.close); //DrawerLayout和ActionBar關聯 toggle.syncState(); drawerLayout.addDrawerListener(toggle); } @Override public boolean onOptionsItemSelected(MenuItem item) { if (toggle.onOptionsItemSelected(item)){ return true; } return super.onOptionsItemSelected(item); } private void init() { ArrayList<Fragment> li = new ArrayList<>(); li.add(new fragment01()); li.add(new fragment02()); li.add(new fragment03()); MypagerAdaper adaper = new MypagerAdaper(getSupportFragmentManager()); adaper.setFragments(li); pager.setAdapter(adaper); tab.addTab(tab.newTab()); tab.addTab(tab.newTab()); tab.addTab(tab.newTab()); tab.setupWithViewPager(pager); tab.getTabAt(0).setText("全部"); tab.getTabAt(1).setText("國內"); tab.getTabAt(2).setText("國際"); } }
XListview Fragment繼承BaseBean類
