我正在实现工具栏和导航抽屉。我用自己的视图自定义工具栏。我的工具栏中有我自己的菜单(汉堡)图标来打开导航抽屉,我在菜单图标(汉堡)上显示徽章计数。所以我想隐藏默认的汉堡图标。
我试过这样:
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(false);
请帮助我。在此先感谢。

调用.setDrawerIndicatorEnabled(false);
你的 ActionBarDrawerToggle
这对我有用:
public void setLogo(String imageUrl) {
ViewGroup toolbarView = (ViewGroup) toolbar.findViewById(R.id.toolbar);
// set an arbitrary logo so the support library adds an ImageView to the toolbar.
// without this, there would be no ImageView elements in the toolbar
// and the following loop would not work
// `empty_drawable` is a simple rectangle of size 100x100 with a bg color
// matching that of the toolbar
// the size really matters because the smaller you set this image, the next logo
// you set will be of that size. If your arbitrary drawable is of size 1x1, then
// the next logo you set will be of the same size. At least that is what happens
// for me when I load an image with Glide.
// Your drawable should have a background color too. I chose the toolbar's
// background color. If you don't set a background color, your app would crash on Kitkat.
toolbar.setLogo(R.drawable.empty_drawable);
for (int i = 0; i < toolbarView.getChildCount(); i++) {
if ((toolbarView.getChildAt(i) instanceof ImageView)) {
ImageView logoView = (ImageView) toolbarView.getChildAt(i);
if (!TextUtils.isEmpty(imageUrl)) {
// this way I can download an image and set the logo that way
Glide.with(MainActivity.this).load(imageUrl).into(logoView);
// I do this because there is no space between logo and the toolbar title
logoView.setPadding(0, 0, 30, 0);
// and this is because of the `else` block
logoView.setVisibility(View.VISIBLE);
} else {
// pass null to `setLogo()` to hide the logo
logoView.setVisibility(View.GONE);
logoView.setPadding(0, 0, 0, 0);
}
break;
}
}
}
这是我的工具栏:
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:animateLayoutChanges="true"
app:popupTheme="@style/AppTheme.PopupOverlay"
app:title="@string/app_name"
tools:ignore="UnusedAttribute" />
这android:animateLayoutChanges="true"
部分让这一切变得非常好。并且tools:ignore="UnusedAttribute"
是因为我的应用程序的最低 SDK 设置为 9。
在您的活动的 onCreate 中尝试此操作:
getActionBar().setIcon(
new ColorDrawable(getResources().getColor(android.R.color.transparent)));
如果您使用的是 AppCompat,请替换getActionBar
为getSupportActionBar
