Android Studio标签查看灰色主题颜色

标签: java xml android-studio

所以我用片段创建了标签视图,一切顺利,除了整个布局颜色是深灰色(不知道为什么),标签线颜色是粉红色(也不知道为什么)。

看起来像enter image description here

另外,正如你所看到的,iz在动作栏和标签栏之间有一个奇怪的间距(也不知道为什么)。

这是我的代码:

Vjezbe.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"
    xmlns:app="http://schemas.android.com/apk/res-auto"

            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

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

    <include layout="@layout/content_vjezbe" />



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

styles.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>

所以,如果有人能指导我完成我的错误,我真的很感激!

谢谢!

除了整个布局颜色是深灰色(不知道为什么)和标签线颜色是粉红色(也不知道为什么)。

尝试更改res/values/colors.xml中的主要和强调颜色,如:

<?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>
  

另外,正如你所看到的,iz在动作栏和标签栏之间有一个奇怪的间距(也不知道为什么)。

我不知道ViewPagerAdapter是什么,但您应该使用FragmentPagerAdapterFragmentStatePagerAdapter这样的内容:

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];
    }
}

并在您的活动中onCreate

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