安卓工作室标签页视图灰色主题颜色



所以我创建了带有片段的选项卡视图,一切都很顺利,除了整个布局颜色是深灰色(不知道为什么)和选项卡行颜色是粉红色(也不知道为什么)。

看起来像这样在这里输入图像描述

此外,如您所见,iz 在操作栏和选项卡栏之间有奇怪的间距(也不知道为什么)。

这是我的代码:

维兹贝.java

package hr.app.liftme.liftmehr;
import android.os.Bundle;
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.support.v7.widget.Toolbar;
import android.view.View;
public class Vjezbe extends AppCompatActivity {
    Toolbar toolbar;
    TabLayout tabLayout;
    ViewPager viewPager;
    ViewPagerAdapter viewPagerAdapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_vjezbe);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        toolbar = (Toolbar)findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        tabLayout = (TabLayout)findViewById(R.id.tabLayout);
        viewPager = (ViewPager)findViewById(R.id.viewPager);
        viewPagerAdapter = new ViewPagerAdapter(getSupportFragmentManager());
        viewPagerAdapter.addFragments(new HomeFragment(), "Prsa");
        viewPagerAdapter.addFragments(new TopFreeFragment(), "Leđa");
        viewPagerAdapter.addFragments(new TopPaidFragment(), "Ramena");
        viewPagerAdapter.addFragments(new TrapeziFragment(), "Trapezi");
        viewPager.setAdapter(viewPagerAdapter);
        tabLayout.setupWithViewPager(viewPager);
    }
}

activity_vjezbe.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />
    </android.support.design.widget.AppBarLayout>
    <include layout="@layout/content_vjezbe" />

</android.support.design.widget.CoordinatorLayout>

样式.xml

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

因此,如果有人可以引导我解决我的错误,我将不胜感激!

谢谢!

此外,整个布局颜色是深灰色(不知道为什么),选项卡行颜色是粉红色(也不知道为什么)。

尝试更改原色和强调色,如下所示res/values/colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorPrimary">#3F51B5</color> <!-- Tab color -->
    <color name="colorPrimaryDark">#303F9F</color> <!-- Status bar color -->
    <color name="colorAccent">#FF4081</color> <!-- Tab indicator color -->
</resources>

此外,如您所见,iz 在操作栏和选项卡栏之间有奇怪的间距(也不知道为什么)。

我不知道ViewPagerAdapter是什么,但你应该使用类似FragmentPagerAdapter或这样的FragmentStatePagerAdapter

public class MyFragmentPagerAdapter extends FragmentPagerAdapter {
    public StorePagerAdapter(FragmentManager manager, String[] titles) {
        super(manager);
        mTitles = titles;
    }
    private String[] mTitles;
    @Override
    public Fragment getItem(int position) {
        if (position == 0) {
            return new HomeFragment();
        } else if (position == 1) {
            return new TopFreeFragment();
        } else if (position == 2) {
            return new TopPaidFragment();
        } else if (position == 3) {
            return new TrapeziFragment();
        }
        return null;
    }
    @Override
    public int getCount() {
        return mTitles.length;
    }
    @Override
    public CharSequence getPageTitle(int position) {
        return mTitles[position];
    }
}

这在您的活动onCreate中:

.
.
String[] titles = new String[] {"Prsa", "Leđa", "Ramena", "Trapezi"};
MyFragmentPagerAdapter myFragmentPagerAdapter = new MyFragmentPagerAdapter(getSupportFragmentManager(), titles);
.
.
