Question

我的通知栏的颜色仍为WHITE，我想将其设置为BLACK但无法执行此操作。

这是style.xml文件

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>

        <item name="android:statusBarColor">@color/navigationBarColor</item>
    </style>

    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="android:statusBarColor">@color/navigationBarColor</item>

        <item name="windowNoTitle">true</item>
    </style>

    <style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

    <style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

</resources>

这是AndroidManifest.xml文件

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.nitesh.alexa">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

这是MainActivity.java文件

package com.example.nitesh.alexa;

import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.design.widget.TabLayout;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.util.Log;
import android.view.Menu;
import android.view.View;


public class MainActivity extends AppCompatActivity implements TabLayout.OnTabSelectedListener{
    JoyStickView joyStickView;


    private TabLayout tabLayout;
    private ViewPager viewPager;


    private ViewPager mViewPager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

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

        //Initializing the tablayout
        tabLayout = (TabLayout)findViewById(R.id.tabLayout);
        tabLayout.addTab(tabLayout.newTab().setText("Manual"));
        tabLayout.addTab(tabLayout.newTab().setText("Status"));
        tabLayout.addTab(tabLayout.newTab().setText("Database"));
        tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);

        viewPager = (ViewPager)findViewById(R.id.pager);
        Pager adapter = new Pager(getSupportFragmentManager(),tabLayout.getTabCount());
        viewPager.setAdapter(adapter);



        tabLayout.setOnTabSelectedListener(this);



    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }


    @Override
    public void onTabSelected(TabLayout.Tab tab) {
        viewPager.setCurrentItem(tab.getPosition());
    }

    @Override
    public void onTabUnselected(TabLayout.Tab tab) {

    }

    @Override
    public void onTabReselected(TabLayout.Tab tab) {

    }


}

请建议我改变背景颜色的方法。

Answer 1

要为状态栏设置自定义颜色，请在扩展材质主题时使用android：statusBarColor属性。默认情况下，android：statusBarColor继承android：colorPrimaryDark。
的值

按照以下步骤之一

步骤1：

打开colors.xml并将navigationBarColor更改为#000000

步骤2：

打开colors.xml并将colorPrimaryDark的值更改为#000000

并删除主题中的android:statusBarColor项。

有关自定义状态栏的详细信息，请查看official docs
