更改工具栏中的图标颜色 [英] Change back icon color in toolbar

问题描述

我将 Android 组件 navigation 用于带有 NavigationView 的 DrawerLayout.

I'm using the Android component navigation for a DrawerLayout with NavigationView.

public class MainActivity extends AppCompatActivity {

    private DrawerLayout drawerLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_activity);
        LoginActivity.toClose.finish();
        LoginViewModel viewModel = ViewModelProviders.of(this).get(LoginViewModel.class);
        Toolbar toolbar = findViewById(R.id.toolbar_menu);
        setSupportActionBar(toolbar);
        ActionBar actionbar = getSupportActionBar();
        assert actionbar != null;

        drawerLayout = findViewById(R.id.drawer_layout);
        NavigationView navigationView = findViewById(R.id.nav_view_menu);
        navigationView.inflateMenu(viewModel.setUserInterface());
        NavController navController = Navigation.findNavController(this, R.id.fragment_main);
        NavigationUI.setupWithNavController(navigationView, navController);
        NavigationUI.setupActionBarWithNavController(this,navController,drawerLayout);
     }
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                drawerLayout.openDrawer(GravityCompat.START);
                return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

一切正常，只是向上按钮"的颜色与我在操作栏中的标题颜色不同.

Everything's ok, except that the "Up button" are in a different color that my title in The action bar.

工具栏的 XML 是:

The XML for the Toolbar is:

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar_menu"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#000000"
    android:textColor="#FFF"
    android:textColorPrimary="#FFF"
    android:theme="@style/Toolbar"
    app:layout_constraintTop_toTopOf="parent"
    app:titleTextColor="#FFF"
    app:title="@string/app_name"/>

标题是白色的，但图标是黑色的.

The title is white, but the icon is black.

我的问题是:如何更改此图标的颜色?

My question is: how can I change the color of this icon?

即使我将主颜色更改为白色并且主题编辑器以白色显示图标，当应用程序运行时，颜色仍然是黑色.

Even if I change the primary color to white and the theme editor show me the icon in white, when the app is running, the color is still black.

我正在构建的应用程序有 minSdkVersion 15我在带有 API 7 SDK 24 的手机中运行它.我还没有在带有 SDK 15 的模拟器中运行.

The app that I'm building has minSdkVersion 15 and I run it in a phone with API 7 SDK 24. I didn't run in the emulator with SDK 15 yet.

推荐答案

使用这种风格

<style name="ToolbarTheme" parent="@style/ThemeOverlay.AppCompat.ActionBar">
        <!-- Customize color of Toolbar -->
        <item name="colorControlNormal">@color/WhiteColor</item>
    </style>

然后在工具栏 XML 的 app:theme="@style/ToolbarTheme" 中使用它:

and then use it in app:theme="@style/ToolbarTheme" in your Toolbar XML :

 <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar_menu"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#000000"
        android:textColor="#FFF"
        android:textColorPrimary="#FFF"
        app:theme="@style/ToolbarTheme"
        app:layout_constraintTop_toTopOf="parent"
        app:titleTextColor="#FFF"
        app:title="@string/app_name"/>
