我正在尝试更改NavigationView
的汉堡包菜单图标,但我无法这样做。
这是我到目前为止所尝试的内容
我有一个基本活动,其中导航抽屉设置已完成。这是相关的一段代码
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.setContentView(R.layout.activity_base_nav);
setSupportActionBar(toolbar);
setupDrawer();
}
private void setupDrawer() {
mDrawerLayout.setDrawerListener(this);
mDrawerToggle = new ActionBarDrawerToggle(this,
mDrawerLayout,
R.string.open,
R.string.close);
mDrawerToggle = new ActionBarDrawerToggle(mContext,
mDrawerLayout,
R.string.open,
R.string.close);
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (getSupportActionBar() != null) {
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(false);
mDrawerToggle.setDrawerIndicatorEnabled(false);
mDrawerToggle.setHomeAsUpIndicator(R.drawable.ic_share_48pt_2x);
}
mDrawerToggle.syncState();
mNavigationView.setNavigationItemSelectedListener(
menuItem -> {
mMenuItem = menuItem.getItemId();
mDrawerUtil.onNavMenuItemClicked(mMenuItem);
mDrawerLayout.closeDrawers();
return true;
});
}
@Override
public void setContentView(int layoutResID) {
getLayoutInflater().inflate(layoutResID, mContainer);
}
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
但它似乎对我不起作用。我也尝试在setDrawerIndicatorEnabled(false)
上调用setHomeAsUpIndicator(R.drawable.ic_share_48pt_2x)
和SupportActionBar
,但这也不起作用。
答案 0 :(得分:23)
以下代码对我很有用,
protected void onCreate(Bundle savedInstanceState) {
...
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(false);
toggle.setDrawerIndicatorEnabled(false);
toggle.setHomeAsUpIndicator(R.drawable.ic_custom_drawer_icon);
...
}
我还必须添加一个工具栏导航点击监听器来监听自定义抽屉图标上的点击事件
protected void onCreate(Bundle savedInstanceState) {
...
toggle.setToolbarNavigationClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
drawer.openDrawer(GravityCompat.START);
}
}
});
...
}
最后,我可以动态更新图标
toggle.setHomeAsUpIndicator(R.drawable.ic_new_icon);
答案 1 :(得分:14)
请使用:
toolbar.post(new Runnable() {
@Override
public void run() {
Drawable d = ResourcesCompat.getDrawable(getResources(), R.mipmap.ic_launcher, null);
toolbar.setNavigationIcon(d);
}
});
您不需要处理接受答案中的setToolbarNavigationClickListener。

您是否尝试查看文档? http://developer.android.com/training/implementing-navigation/nav-drawer.html
我在其中找到了这段代码:
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close) {
/** Called when a drawer has settled in a completely closed state.*/
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
getActionBar().setTitle(mTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getActionBar().setTitle(mDrawerTitle);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};

这对我有用:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
setSupportActionBar(toolbar)
val toggle = ActionBarDrawerToggle(
this, drawer_layout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close)
//toggle.isDrawerSlideAnimationEnabled = false
toggle.isDrawerIndicatorEnabled = false
toggle.setToolbarNavigationClickListener {
if (drawer_layout.isDrawerOpen(GravityCompat.START))
drawer_layout.closeDrawer(GravityCompat.START)
else
drawer_layout.openDrawer(GravityCompat.START)
}
toggle.setHomeAsUpIndicator(AppCompatResources.getDrawable(this, R.drawable.ic_android_black_24dp))
drawer_layout.addDrawerListener(toggle)
toggle.syncState()
nav_view.setNavigationItemSelectedListener(this)
}
override fun onBackPressed() {
if (drawer_layout.isDrawerOpen(GravityCompat.START)) {
drawer_layout.closeDrawer(GravityCompat.START)
} else {
super.onBackPressed()
}
}
override fun onNavigationItemSelected(item: MenuItem): Boolean {
when (item.itemId) {
...
}
drawer_layout.closeDrawer(GravityCompat.START)
return true
}
答案 4 :(得分:0)
将工具栏设置为ActionBar。
然后使用actionBar.setDisplayHomeAsUpEnabled(true);
代码段:
Toolbar toolbar = findViewById(R.id.customFBToolbar);
setSupportActionBar(toolbar);
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeAsUpIndicator(R.drawable.myham); // This is the line where you set the drawable
actionBar.setDisplayShowTitleEnabled(false);
