Android.support.v7 Toolbar & DrawerLayout- how to hide a hamburger icon

Question

I am implementing a toolbar and a navigation box. I customized my toolbar with my own views. I have my own menu (hamburger) on the toolbar to open the navigation box, and I show the number of icons on my menu icon (Hamburger). So I want to hide the default hamburgers icon.

I tried like this:

getSupportActionBar().setDisplayHomeAsUpEnabled(false);
getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(false);

Please help me. Thanks in advance.

Answer 1

call .setDrawerIndicatorEnabled(false);into your ActionBarDrawerToggle

This works for me:

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;
    }
  }
}

:

<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" />

android:animateLayoutChanges="true" . tools:ignore="UnusedAttribute" , SDK 9.

onCreate:

getActionBar().setIcon(
   new ColorDrawable(getResources().getColor(android.R.color.transparent)));

AppCompat, getActionBar getSupportActionBar.
