Problems with Home button in the Toolbar

Question

I know it's a common question but I tried a lot of solutions of StackOverflow and any solution works.

I want to show the home button in the toolbar but it shows the back button or nothing.

I tried different codes like:

    getSupportActionBar().setHomeButtonEnabled(true);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setDisplayShowHomeEnabled(true);
    getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(true);

Now I have the code:

    setSupportActionBar(toolbar);
    getSupportActionBar().setHomeButtonEnabled(true);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

and it shows the back button.

Any solution to show the Home button? Thanks for the help.

I'm sorry if my English is too bad.

You should use a DrawerToggle to manage the state of the DrawerLayout.

Using a custom icon is really not a good way to achieve this, you should use Material Colors to change the color of the toggle button.

This is a working example of this :

        mToolbar = (Toolbar) findViewById(R.id.toolbar);
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

        setSupportActionBar(mToolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);

        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, mToolbar,  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);

                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
            }

            /** Called when a drawer has settled in a completely open state. */
            public void onDrawerOpened(View drawerView) {
                super.onDrawerOpened(drawerView);

                invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
            }
        };


        // Set the drawer toggle as the DrawerListener
        mDrawerLayout.setDrawerListener(mDrawerToggle);
        mDrawerToggle.syncState();
