一、style方式

<style name="ToolBarStyle" parent="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="actionMenuTextColor">@android:color/white</item> <!--  敲定顏色-->
<item name="android:textSize">15sp</item> <!--  搞掂字型大小-->
<item name="android:textStyle"
 
>normal</item>
</style>

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/colorPrimary"
 
android:minHeight="?attr/actionBarSize"
app:colorControlNormal="@android:color/white"
app:navigationIcon="@drawable/back"
app:theme="@style/ToolBarStyle">

二、ActionProvider方式(方式1一般寫完之後全域性都變了，如果需要動態更換或者個別地方更改則可以使用該方式)

public class MainActionProvider extends ActionProvider {


    TextView tvTitle;
View.OnClickListener clickListener
 
;
public MainActionProvider(Context context) {
        super(context);
}

    @Override
public View onCreateActionView() {
        Log.e("toolbar-menu", "onCreateActionView");
tvTitle = new TextView(getContext());
ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.MATCH_PARENT);
tvTitle.setLayoutParams(params);
tvTitle.setGravity(Gravity.CENTER);
tvTitle.setPadding(DensityUtils.dp2px(getContext(),10),0,DensityUtils.dp2px(getContext(),10),0);
tvTitle.setText(R.string.exit);
tvTitle.setBackgroundResource(R.drawable.half_translucent_selector);
tvTitle.setTextColor(BSSUtils.getColor(R.color.red_exit));
tvTitle.setOnClickListener(clickListener);
return tvTitle;//或者自己寫的佈局inflate為View
}


    @Override
public void onPrepareSubMenu(SubMenu subMenu) {

    }

    @Override
public boolean hasSubMenu() {
        return true;
}

    public void setonClickListener(View.OnClickListener listener){
        clickListener = listener;
}

    public void setTvTitle(String title){
        tvTitle.setText(title);
}

}

在Activity中新增如下程式碼

    @Override
public boolean onPrepareOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main_menu, menu);
mLogoutMenuItem = menu.findItem(R.id.logout);
mLogoutMenuItem.setVisible(false);
//        mLogoutMenuItem.getActionView();
MainActionProvider actionProvider = (MainActionProvider) MenuItemCompat.getActionProvider(mLogoutMenuItem);
actionProvider.setonClickListener(new View.OnClickListener() {
            @Override
public void onClick(View v) {
                //點選事件}
        });
        return true;
}

    @Override
public boolean onCreateOptionsMenu(Menu menu) {
        return super.onCreateOptionsMenu(menu);
}
