在编写此线程之前,我已尝试实现我在stackoverflow中找到的不同解决方案,但没有正常工作。
我正在开发一个使用自定义导航抽屉的Android应用程序,我必须更改操作栏的标准图标(现在是工具栏,对吗?)和设置图标。
这是我的代码:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitleTextColor(Color.parseColor("#009754"));
setSupportActionBar(toolbar);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
这就是我尝试实施的目标:
此解决方案不起作用:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitleTextColor(Color.parseColor("#009754"));
toolbar.setNavigationIcon(R.drawable.ic_draw);
setSupportActionBar(toolbar);
此解决方案不起作用:
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(false);
toggle.setDrawerIndicatorEnabled(false);
toggle.setHomeAsUpIndicator(R.drawable.ic_custom_drawer_icon);
我不明白为什么我不能改变图标,我不知道是什么问题...

简单而优雅的解决方案
放置
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.dashboardicon);
//您的图标
后
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer,toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
导航活动中的整体解决方案
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer,toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.dashboardicon);
navigationView= (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
注意:它不需要任何setNavigationOnClickListener()

禁用?cos
These functions give the obvious trigonometric functions. They
respectively compute the cosine, sine, tangent, arc-cosine,
arc-sine, arc-tangent, and the two-argument arc-tangent.
的抽屉指示符:
ActionBarDrawerToggle
然后:
toggle.setDrawerIndicatorEnabled(false);

Just use this :
toolbar.post(new Runnable() {
@Override
public void run() {
Drawable d = ResourcesCompat.getDrawable(getResources(), R.mipmap.ic_launcher, null);
toolbar.setNavigationIcon(d);
}
});
