android - 如何删除默认工具栏菜单项并替换为不同的图标？

Question

我正在使用来自 v7.widget.Toolbar 支持库和 v7.app.ActionBarActivity 的工具栏。当工具栏上的 onCreateOptionsMenu 膨胀时，我在工具栏的最左侧看到一个标准的“后退”箭头，在工具栏的最右侧看到标准的“溢出”点。

我想隐藏或禁用这些默认图标并替换为另一组 Android 推荐图标。关于如何修复的任何想法？

MyActiviy.java:

公共(public)类 MyActivity 扩展 ActionBarActivity {

private Toolbar toolbar;

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

        toolbar = (Toolbar) findViewById(R.id.toolbar);
        if (toolbar != null) {
            setSupportActionBar(toolbar); 
            getSupportActionBar().setTitle("sc");
            getSupportActionBar().setHomeButtonEnabled(true); 
            getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        }
...

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return super.onCreateOptionsMenu(menu);
...

这就是我使用工具栏的方式。它是一个独立的工具栏，可让您更好地控制其在类中的功能。

activity_home.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.Toolbar
        android:id="@+id/tool_bar"
        android:layout_height="56dp"
        android:layout_width="match_parent"
        android:elevation="5dp"
        app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        android:background="@color/primary" />

    <FrameLayout
        android:layout_below="@+id/tool_bar"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <!-- Main Content-->
    </FrameLayout>

</RelativeLayout>

样式

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/primary</item>
    <item name="colorPrimaryDark">@color/secondary</item>
    <item name="colorAccent">@color/black</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
    <item name="windowActionBarOverlay">true</item>
    <item name="android:windowActionBarOverlay">true</item>
    <item name="windowActionModeOverlay">true</item>
</style>

**我的 Activity **

public class MyActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        // Set navigation icon
        toolbar.setNavigationIcon(getResources().getDrawable(R.drawable.ic_launcher));
        // Navigation onClickLister
        toolbar.setNavigationOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // finish(); // or your action here
            }
        });
        //Inflate menu
        toolbar.inflateMenu(R.menu.menu_my);
        // menu items 
        toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {
                int id = item.getItemId();
                if (id == R.id.action_settings) {
                    // Your action here
                    return true;
                }
                return false;
            }
        });
        // Clear toolbar icons 
        toolbar.getMenu().clear(); // I believe this is what you are looking for
        // Set title
        toolbar.setTitle("Title");
        //Set SubTitle
        toolbar.setSubtitle("Sub Title");

    }
}
