DrawerLayout的使用

mToolbar = (Toolbar) findViewById(R.id.tool_bar);
mToolbar.setTitle("Kevin");//customize the title,个性化设置title
mToolbar.setTitleTextColor(ContextCompat.getColor(this, R.color.white));//设置title颜色
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);//show back button and make it enabled
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

mActionBarDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, mToolbar, R.string.drawer_layout_open, R.string.drawer_layout_close);
mActionBarDrawerToggle.setDrawerIndicatorEnabled(true);
mActionBarDrawerToggle.setHomeAsUpIndicator(R.mipmap.ic_launcher);//channge the icon,改变图标
mActionBarDrawerToggle.syncState();////show the default icon and sync the DrawerToggle state,如果你想改变图标的话，这句话要去掉。这个会使用默认的三杠图标
mDrawerLayout.setDrawerListener(mActionBarDrawerToggle);
mDrawerLayout.setStatusBarBackgroundColor(ContextCompat.getColor(this, R.color.green));//设置状态栏颜色
