DrawerLayout

工程源码

• 创建导航菜单
  res/menu/menu-natigation.xml

创建导航的布局 res/layout/navigation.xml

在activity_main.xml中加入DrawerLayout ,是DrawerLayout作为对顶层,使CoordinatorLayout作为它的
子级

    ......
  

和CoordinatorLayout的同一级添加NavigationView

在MainActivity.javaonCreate中添加相关的逻辑

NavigationView navigationView = (NavigationView)findViewById(R.id.nav_view);
mDrawerLayout = (DrawerLayout)findViewById(R.id.drawer);
ActionBar supportActionBar = getSupportActionBar();
if(supportActionBar != null){
    supportActionBar.setHomeAsUpIndicator(R.drawable.ic_menu_white_24dp);
    supportActionBar.setDisplayHomeAsUpEnabled(true);
}
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
    @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem item) {
        item.setChecked(true);
        mDrawerLayout.closeDrawers();;
        return true;
    }
});

相应左上角的menu，打开导航

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    if(id == android.R.id.home){
        mDrawerLayout.openDrawer(GravityCompat.START);
    }
    return super.onOptionsItemSelected(item);
}
