android - 如何在 Android 中更改工具栏标题的颜色？

Question

我正在开发一个 Android 应用程序，我想将工具栏的标题设为白色。

我删除了默认工具栏并向我的 Activity 添加了一个工具栏，但我无法弄清楚如何将工具栏标题的颜色更改为白色

主 Activity .java

package com.example.acer.videoapp;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;


public class MainActivity extends AppCompatActivity {

    Toolbar toolbar;
    ListView listView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        toolbar = (Toolbar) findViewById(R.id.toolbar);
        toolbar.setTitle(getResources().getString(R.string.app_name));
        //toolbar.setTitleTextColor(white);
        listView = (ListView) findViewById(R.id.listView);


        ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_expandable_list_item_1,getResources().getStringArray(R.array.subjects));

        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int i, long id) {
                Intent intent = new Intent(MainActivity.this, SecondActivity.class);
                intent.putExtra("Subject", listView.getItemAtPosition(i).toString());
                startActivity(intent);
            }
        });
        listView.setAdapter(mAdapter);

    }
}

使用 toolbar.setTitleTextColor() 方法设置 Toolbar 文本的颜色

 toolbar = (Toolbar) findViewById(R.id.toolbar);
 toolbar.setTitle(getResources().getString(R.string.app_name));
 toolbar.setTitleTextColor(getColor(R.color.white));
