qq动画侧滑和滑动菜单导航 Android程序开发之使用Design包实现QQ动画侧滑效果和滑动菜单导航
南尘 人气:0Google在2015的IO大会上,给我们带来了更加详细的Material Design设计规范,同时,也给我们带来了全新的Android Design Support Library,在这个support库里面,Google给我们提供了更加规范的MD设计风格的控件。最重要的是,Android Design Support Library的兼容性更广,直接可以向下兼容到Android 2.2。这不得不说是一个良心之作。
使用方法很简单,只需要添加一句依赖
compile 'com.android.support:design:24.0.0'
先用TabLayout和SnackBar以及Navigation实现QQ侧滑动画效果和滑动
项目已经同步至:https://github.com/nanchen2251/designNavigation-and-tabLayout
上个整体效果图
首先带来的是TabLayout
Tab滑动切换View并不是一个新的概念,但是Google却是第一次在support库中提供了完整的支持,
而且,Design library的TabLayout 既实现了固定的选项卡 - view的宽度平均分配,
也实现了可滚动的选项卡 - view宽度不固定同时可以横向滚动。选项卡可以在程序中动态添加,
但大部分时间我们都不会这样用,通常滑动布局都会和ViewPager配合起来使用,所以,我们需要ViewPager来帮忙:
通过一句话setupWithViewPager,我们就把ViewPager和TabLayout结合了起来。
上个运行图:
看代码
首先是主页面的XML文件
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="com.example.nanchen.designtablayoutdemo.MainActivity"> <android.support.design.widget.TabLayout android:layout_width="match_parent" app:tabBackground="@color/colorPrimaryDark" app:tabTextColor="@android:color/white" app:tabSelectedTextColor="#04b4ae" android:layout_height="wrap_content" android:id="@+id/main_tab_layout"/> <android.support.v4.view.ViewPager android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" android:id="@+id/main_vp"/> </LinearLayout>
其中由于必须TabLayout控件是Design包下的,所以必须加上
xmlns:app="http://schemas.android.com/apk/res-auto"<br><br>这样才可以使用自定义它的属性。它的属性有很多,这样简单使用几个,更多的大家可以去尝试。<br>这里,我只滚动了三个,若是你的APP tab标签多的话,
app:tabMode="scrollable" 必须指定这个属性,不然你会发现看不到,如果标签数少,还是建议设置为固定的,那样才会等分。
<br><br>其次是Fragment的XML文件<br><br> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.example.nanchen.designtablayoutdemo.BlankFragment"> <!-- TODO: Update blank fragment layout --> <TextView android:layout_width="match_parent" android:layout_height="match_parent" android:textSize="30sp" android:gravity="center" android:id="@+id/fg_text" android:text="@string/hello_blank_fragment"/> </FrameLayout>
MainActivity.java
package com.example.nanchen.designtablayoutdemo; import android.os.Bundle; import android.support.design.widget.TabLayout; import android.support.v4.view.ViewPager; import android.support.v7.app.AppCompatActivity; import java.util.ArrayList; import java.util.List; public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ViewPager vp = (ViewPager) findViewById(R.id.main_vp); TabLayout tabLayout = (TabLayout) findViewById(R.id.main_tab_layout); List<String> list = new ArrayList<>(); for (int i = 1; i < 4; i++) { // list.add(String.format(Locale.CHINA,"第02d%页",i)); list.add("第"+i+"页"); } vp.setAdapter(new MyAdapter(getSupportFragmentManager(),list)); tabLayout.setupWithViewPager(vp); } }
FragmenT用于存放下面的数据
package com.example.nanchen.designtablayoutdemo; import android.os.Bundle; import android.support.annotation.Nullable; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.TextView; /** * A simple {@link Fragment} subclass. */ public class BlankFragment extends Fragment { public BlankFragment() { // Required empty public constructor } public static BlankFragment newInstance(String text) { Bundle args = new Bundle(); args.putString("text",text); BlankFragment fragment = new BlankFragment(); fragment.setArguments(args); return fragment; } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment return inflater.inflate(R.layout.fragment_blank, container, false); } @Override public void onViewCreated(View view, @Nullable Bundle savedInstanceState) { super.onViewCreated(view, savedInstanceState); TextView text = (TextView) view.findViewById(R.id.fg_text); String str = getArguments().getString("text"); text.setText(str); } }
需要一个PagerAdapter
自定义一个。
package com.example.nanchen.designtablayoutdemo; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentPagerAdapter; import java.util.List; /** * Created by 南尘 on 2016/7/12. */ public class MyAdapter extends FragmentPagerAdapter { private List<String> list; public MyAdapter(FragmentManager fm, List<String> list) { super(fm); this.list = list; } @Override public Fragment getItem(int position) { return BlankFragment.newInstance(list.get(position)); } @Override public int getCount() { return list.size(); } @Override public CharSequence getPageTitle(int position) { return list.get(position); } }
2)再来看看如何使用Navigation和DrawerLayout实现侧滑功能的动画演示
前面讲解了Design包下的TabLayout的使用,下面将带来NavagationView和DrawLayout以及toolbar的联动。
NavigationView 通过提供抽屉导航所需的框架让实现更简单,同时它还能够直接通过菜单资源文件直接生成导航元素。把NavigationView作为DrawerLayout的内容视图来使用。NavigationView处理好了和状态栏的关系,可以确保NavigationView在API21+设备上正确的和状态栏交互。
以下代码在前面代码的基础上修改。
MainActivity.java
package com.example.nanchen.designtablayoutdemo; import android.os.Bundle; import android.support.design.widget.NavigationView; import android.support.design.widget.TabLayout; import android.support.v4.view.GravityCompat; import android.support.v4.view.ViewPager; import android.support.v4.widget.DrawerLayout; import android.support.v7.app.ActionBarDrawerToggle; import android.support.v7.app.AppCompatActivity; import android.support.v7.widget.Toolbar; import android.view.MenuItem; import android.widget.Toast; import java.util.ArrayList; import java.util.List; public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener { private DrawerLayout drawerLayout; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ViewPager vp = (ViewPager) findViewById(R.id.main_vp); TabLayout tabLayout = (TabLayout) findViewById(R.id.main_tab_layout); Toolbar toolbar = (Toolbar) findViewById(R.id.main_toolbar); drawerLayout = (DrawerLayout) findViewById(R.id.main_drawerlayout); //设置Toolbar和DrawerLayout实现动画和联动 this.setSupportActionBar(toolbar); ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,0,0); drawerLayout.addDrawerListener(toggle);//设置监听 toggle.syncState();//加上同步 getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(true); List<String> list = new ArrayList<>(); for (int i = 1; i < 5; i++) { // list.add(String.format(Locale.CHINA,"第02d%页",i)); list.add("第"+i+"页"); } vp.setAdapter(new MyAdapter(getSupportFragmentManager(),list)); tabLayout.setupWithViewPager(vp); NavigationView navigationView = (NavigationView) findViewById(R.id.main_navigation); navigationView.setNavigationItemSelectedListener(this); } @Override public boolean onNavigationItemSelected(MenuItem item) { switch (item.getItemId()) { case R.id.menu_item1: Toast.makeText(this,"你点击了菜单1",Toast.LENGTH_SHORT).show(); break; case R.id.menu_item2: Toast.makeText(this,"你点击了菜单2",Toast.LENGTH_SHORT).show(); break; case R.id.menu_item3: Toast.makeText(this,"你点击了菜单3",Toast.LENGTH_SHORT).show(); break; case R.id.menu_item4: Toast.makeText(this,"你点击了菜单4",Toast.LENGTH_SHORT).show(); break; } drawerLayout.closeDrawer(GravityCompat.START); return true; } }
