62、常规控件（5）Navigation View –美观的侧滑视图

1、main_layout.xml

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <include layout="@layout/activity_main"/>
    <!--
        android:fitsSystemWindows="true|false":适合系统窗口
    -->
    <android.support.design.widget.NavigationView
        android:id="@+id/navigetion_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="left"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/head_view"
        app:menu="@menu/menu_main">
    </android.support.design.widget.NavigationView>

</android.support.v4.widget.DrawerLayout>

 

2、@layout/head_view  侧滑布局文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical">
    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher"/>
</LinearLayout>

 

3、MainActivity.java

 

package com.example.com.designdemo;

import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
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.main_layout);

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

        List<String> titles = new ArrayList<String>();
        List<Fragment> fragments = new ArrayList<Fragment>();
        for (int i=0; i<10; i++) {
            String title = "Tab"+ (i+1);
            tabs.addTab(tabs.newTab().setText(title));
            titles.add(title);

            Fragment fragment = new TestOneFragment(title);
            fragments.add(fragment);
        }

        ViewPager viewpager = (ViewPager) this.findViewById(R.id.viewpager);
        TestOneAdapter mAdapter = new TestOneAdapter(getSupportFragmentManager(), titles, fragments);
        viewpager.setAdapter(mAdapter);
        tabs.setupWithViewPager(viewpager);
        tabs.setTabsFromPagerAdapter(mAdapter);

        // 控制侧滑菜单的显示和隐藏
        //DrawerLayout drawer_layout = (DrawerLayout) this.findViewById(R.id.drawer_layout);
        //drawer_layout.closeDrawer();
    }

}
