标签: android-tablayout

我想在设计支持库的tablayout中嵌入自定义字体.我尝试设置已设置字体的自定义视图.但它没有用.只是出现系统字体.

我做的是,

mAdpater = new CustomPagerAdapter(getSupportFragmentManager());
mFragmentPager.setAdapter(mAdpater);
mTabs.setupWithViewPager(mFragmentPager);
Typeface tf = Typeface.createFromAsset(getAssets(), "fonts/myFont.ttf");
for (int i = 0; i < mTabs.getTabCount(); i++) {
    TextView tv = new TextView(this);
    tv.setText(mAdpater.getPageTitle(i));
    tv.setTypeface(tf);
    mTabs.getTabAt(i).setCustomView(tv);
}

欢迎任何建议.

我正在使用设计支持库来创建选项卡.默认情况下,它会创建带文本的选项 如何创建仅带图标的标签？此外,如果它是当前选定的选项卡,我想更改图标颜色.

我使用android支持库实现选项卡布局,它看起来像

这里标签宽度不适合屏幕,我的布局是

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">


    <android.support.design.widget.TabLayout
        android:id="@+id/sliding_tabs"

        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabMode="scrollable" />

    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="0px"
        android:layout_weight="1"
        android:background="@android:color/white" />

</LinearLayout>

我正在尝试使用Eclipse创建基于Google"材料设计"的菜单选项卡,但是我收到了一个错误:

我正在使用设计库支持TabLayout,我试图在Tab被按下或ViewPager被滑动时更改工具栏的标题.但到目前为止无法取得任何成功.这是以下代码: -

public class ActivityHomePage extends AppCompatActivity {
    private TabLayout tabLayout;
    private ViewPager viewPager;
    Toolbar toolbar;
    DesignDemoPagerAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_homepage);

        toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayShowTitleEnabled(false);




        viewPager = (ViewPager) findViewById(R.id.viewpager);
        setupViewPager(viewPager);
      //  viewPager.getAdapter().getPageTitle();
        tabLayout = (TabLayout) findViewById(R.id.tablayout);
        tabLayout.setupWithViewPager(viewPager);
        setupTabIcons();


    }
    private int[] tabIcons = {

            R.drawable.ic_action_star,
            R.drawable.ic_action_heart,
            R.drawable.ic_action_square
    };
    private void setupViewPager(ViewPager viewPager) {
        adapter = new DesignDemoPagerAdapter(getSupportFragmentManager());

        adapter.addFrag(new FragmentStar(), "star");
        adapter.addFrag(new FragmentHeart(), "heart");
        adapter.addFrag(new FragmentSquare(), "square");
        viewPager.setAdapter(adapter);



    }



    @Override
    public boolean onCreateOptionsMenu(Menu menu) …

任何人都知道为什么在Android中新生成的选项卡式活动中底部是否在屏幕外？

ViewPager对于整个屏幕来说太长了

    <android.support.v4.view.ViewPager
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />

如果您将它们对齐到屏幕底部,则55dp中的子片段中的所有视图都不在屏幕上.

谢谢,

保罗

我按如下方式设置tablayout,

        TextView tabOne = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
        tabOne.setText("Status");
        tabOne.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.status, 0, 0);
        tabLayout.getTabAt(0).setCustomView(tabOne);

        TextView tabTwo = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
        tabTwo.setText("Rating");
        tabTwo.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.rateit, 0, 0);
        tabLayout.getTabAt(1).setCustomView(tabTwo);
}

如何更改所选标签的图标？即时通讯使用tablayout.

我有一个活动toolbar,Tablayout,viewpager 与这样的片段

我想toolbar对所有片段实施 材料搜索

像那样

但问题是TAB Bar. 我想在搜索打开时隐藏标签栏(呼叫,聊天,联系人),并在搜索关闭时取消隐藏它

如何隐藏标签栏？

我正在使用此库进行材料搜索视图实现

我有一个使用viewpager设置TabLayout.viewpager设置了适配器.向适配器添加了11个片段,每个片段都有一个recyclerview.当我运行应用程序时,在片段之间滑动变慢.谁能告诉我这个问题的原因？

我的主要活动:

    myTabLayout.setTabMode(TabLayout.MODE_SCROLLABLE);


    mainViewPager = (ViewPager) findViewById(R.id.mainViewPager);
    tabLayoutAdapter = new TabLayoutAdapter(getSupportFragmentManager());
    tabLayoutAdapter.addFragment(new HomeFragment());
    tabLayoutAdapter.addFragment(new ClipFragment());
    tabLayoutAdapter.addFragment(new MovieFragment());
    tabLayoutAdapter.addFragment(new SerialFragment());
    tabLayoutAdapter.addFragment(new MusicFragment());
    tabLayoutAdapter.addFragment(new BookFragment());
    tabLayoutAdapter.addFragment(new PixFragment());
    tabLayoutAdapter.addFragment(new GameFragment());
    tabLayoutAdapter.addFragment(new NewsFragment());
    tabLayoutAdapter.addFragment(new LiveFragment());
    tabLayoutAdapter.addFragment(new AdvancedSearchFragment());
    mainViewPager.setAdapter(tabLayoutAdapter);
    myTabLayout.setupWithViewPager(mainViewPager);

我的适配器:

public class TabLayoutAdapter extends FragmentStatePagerAdapter {
List<Fragment> tabPages = new ArrayList<>();

public TabLayoutAdapter(FragmentManager fm) {
    super(fm);
}

@Override
public Fragment getItem(int position) {
    return tabPages.get(position);
}

@Override
public int getCount() {
    return tabPages.size();
}

public void addFragment(Fragment page){
    tabPages.add(page);
}

}

样本片段:

public class …
