Question

我使用了工具栏并使用了设计库。工具栏导航图标和后退箭头图标在Android 5.0设备上显示为白色。但在Android 4.x设备上，它显示为黑色图标。如何将图标显示为白色在Android 5.0和Android 4.x设备上。

MainActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);


    final Drawable upArrow = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);

    upArrow.setColorFilter(getResources().getColor(android.R.color.white), PorterDuff.Mode.SRC_ATOP);

    toolbar.setNavigationIcon(upArrow);

    setSupportActionBar(toolbar);

    mDrawerLayout = (DrawerLayout)findViewById(R.id.drawer_layout);

    mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,toolbar, R.string.app_name, R.string.app_name){

        @Override
        public void onDrawerClosed(View drawerView) {
            super.onDrawerClosed(drawerView);
            fab1.setVisibility(View.VISIBLE);
        }

        @Override
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
            fab1.setVisibility(View.GONE);
        }
    };
    mDrawerLayout.setDrawerListener(mDrawerToggle);

    NavigationView navigationView = (NavigationView) findViewById(R.id.navigation_view);
    navigationView.setNavigationItemSelectedListener(this);
}

@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    mDrawerToggle.syncState(); /* if comment this line white color applied,but only arrow displayed,not display nav icon(three line icon)*/
}


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

toolbar.xml

Answer 1

您已经发布了答案：）

    //final Drawable upArrow = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);

    //upArrow.setColorFilter(getResources().getColor(android.R.color.white), PorterDuff.Mode.SRC_ATOP);

    //toolbar.setNavigationIcon(upArrow);

这是有效的。测试4.4.2

我认为你有太多的尝试，这有点混乱。
