更改操作栏android上的导航抽屉图标

Question

我使用ActionBar在我的应用程序中创建了一个NavigationDrawer.

如上图所示,我想将NavigationDrawer切换按钮图标更改为我想要的内容.我该怎么改变它？

这是我的代码: -

mDrawerList.setOnItemClickListener(new SlideMenuClickListener());


    // enabling action bar app icon and behaving it as toggle button
    getActionBar().setDisplayHomeAsUpEnabled(true);
    getActionBar().setHomeButtonEnabled(true);

    mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
            R.drawable.hamburger_button, //nav menu toggle icon
            R.string.app_name, // nav drawer open - description for accessibility
            R.string.app_name // nav drawer close - description for accessibility
            ) {
        public void onDrawerClosed(View view) 
        {

            getActionBar().setTitle(mTitle);
            // calling onPrepareOptionsMenu() to show action bar icons
            invalidateOptionsMenu();
        }

        public void onDrawerOpened(View drawerView) {
            getActionBar().setTitle("Settings");
            // calling onPrepareOptionsMenu() to hide action bar icons
            invalidateOptionsMenu();
        }
    };
    mDrawerLayout.setDrawerListener(mDrawerToggle);
@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    // Sync the toggle state after onRestoreInstanceState has occurred.
    mDrawerToggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    // Pass any configuration change to the drawer toggls
    mDrawerToggle.onConfigurationChanged(newConfig);
}

如果我尝试将其更改为R.drawable.hamburger_button 它仍然显示默认图标

要使用v7 ActionBarDrawerToggle将抽屉指示器图标替换为您自己的drawable(非动画),您可以执行以下操作:

//After instantiating your ActionBarDrawerToggle
mDrawerToggle.setDrawerIndicatorEnabled(false);
Drawable drawable = ResourcesCompat.getDrawable(getResources(), R.drawable.your_custom_icon, getActivity().getTheme());
mDrawerToggle.setHomeAsUpIndicator(drawable);
mDrawerToggle.setToolbarNavigationClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if (mDrawerLayout.isDrawerVisible(GravityCompat.START)) {
            mDrawerLayout.closeDrawer(GravityCompat.START);
        } else {
            mDrawerLayout.openDrawer(GravityCompat.START);
        }
    }
});

尝试使用setHomeAsUpIndicator()手动更改图标.

喜欢,

ActionBar actionBar = getActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeAsUpIndicator(R.drawable.ic_drawer);

和

ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(...){};
mDrawerToggle.setHomeAsUpIndicator(R.drawable.ic_drawer_toggle);

请确保包含这些内容以正确同步图标的状态。

@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    // Sync the toggle state after onRestoreInstanceState has occurred.
    mDrawerToggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    mDrawerToggle.onConfigurationChanged(newConfig);
}
