这是我的代码我想要设置自定义标签，就像我选择第一个标签然后指标和标签宽度或第一个标签的重量我应该增加而第二个标签减少只显示图像不是文本相同如果我们选择第二个标签然后第一个标签指示器或重量应该减少，第二个标签文本和图像应该可见：

我目前的屏幕：

在此你可以看到选项卡一是选中的图像和文本是可见的选项卡第二个未被取消选择所以唯一的图像是可见的没有文字：

但我的预期标签是这样的：

当我们选择标签然后指示器和标签的宽度增加而标签2减少时请查看这个请告诉我如何实现这一点.thanx

Answer 1

我从here复制了解决方案，也许它会对你有用

 Display display = getWindowManager().getDefaultDisplay();
    int width = display.getWidth();

    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

   TabHost mTabHost = getTabHost();

   mTabHost.addTab(mTabHost.newTabSpec("tab_test1")
           .setIndicator((""),getResources().getDrawable(R.drawable.mzl_05))
     .setContent(new Intent(this, NearBy.class)));
   mTabHost.addTab(mTabHost.newTabSpec("tab_test2")
           .setIndicator((""),getResources().getDrawable(R.drawable.mzl_08))
     .setContent(new Intent(this, SearchBy.class)));
           mTabHost.setCurrentTab(0);
           mTabHost.getTabWidget().getChildAt(0).setLayoutParams(new
             LinearLayout.LayoutParams((width/2)-2,50));
      mTabHost.getTabWidget().getChildAt(1).setLayoutParams(new
                 LinearLayout.LayoutParams((width/2)-2,50));

您可以尝试其他代码tabHost.getTabWidget().getChildAt(0).getLayoutParams().width = 50;

Answer 2

您可以轻松实现带标签布局的自定义标签，试试这个

  public void setupTabView(){
    for (int i = 0; i < tabLayout.getTabCount(); i++) {
        tabLayout.getTabAt(i).setCustomView(R.layout.custom_tab);
        TextView tab_name = (TextView) tabLayout.getTabAt(i).getCustomView().findViewById(R.id.txt_tab_name);
        tab_name.setText("" + tabNames[i]);
    }
}

制作一个名为custom_tab的可绘制文件

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

     <TextView
         android:id="@+id/txt_tab_name"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:gravity="center"
         android:textSize="14sp" />


</RelativeLayout>

Answer 3

创建自定义标签布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="48dp">

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:orientation="horizontal">

    <TextView
        android:id="@+id/tv_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="@drawable/tab_text_color_selector"
        android:textSize="@dimen/medium_text"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/tv_count"
        android:layout_width="20dp"
        android:layout_height="20dp"
        android:layout_marginStart="4dp"
        android:background="@drawable/badge_background"
        android:gravity="center"
        android:textColor="@color/colorPrimary"
        android:textSize="@dimen/medium_text"
        android:textStyle="bold"
        android:visibility="gone" />
</LinearLayout>

tabTitles = new String[]{getString(R.string.main_tab_call), getString(R.string.main_tab_chat), getString(R.string.main_tab_contact)};

  private void setupTabIcons() {
    for (int i = 0; i < tabTitles.length; i++) {
        mTabLayout.getTabAt(i).setCustomView(prepareTabView(i));
    }
}


private View prepareTabView(int pos) {
    View view = getLayoutInflater().inflate(R.layout.custom_tab, null);
    TextView tv_title = view.findViewById(R.id.tv_title);
    TextView tv_count = view.findViewById(R.id.tv_count);
    tv_title.setText(tabTitles[pos]);
    return view;
}

Answer 4

使用以下代码。它有两个选择。（i）创建自定义TabLayout （ii）更改自定义制式布局文本的颜色

（i）自定义TabLayout

 <TextView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/tab"
android:layout_width="match_parent"
android:textSize="15sp"
android:gravity="center"
android:textColor="@color/txtbox_text_color_darek"
android:layout_height="match_parent"
/>

源代码是：

        TextView tabOne = (TextView) 
        LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
        tabOne.setText("KPIs" + " ");
        tabOne.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.alert_gray, 
        0);
        Objects.requireNonNull(tabLayout.getTabAt(4)).setCustomView(tabOne);

（II）更改颜色

     private void custom_tablayout_select_unselected_four(final TextView tabOne) {

     tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            if (Objects.requireNonNull(tabLayout.getTabAt(4)).isSelected()) {
                tabOne.setTextColor(getResources().getColor(R.color.text_color_darkblue));
            } else {


      tabOne.setTextColor(getResources().getColor(R.color.txtbox_text_color_darek));
            }

        }

        @Override`
        public void onTabUnselected(TabLayout.Tab tab) {
            // tabOne.setTextColor(Color.GREEN);
        }

        @Override
        public void onTabReselected(TabLayout.Tab tab) {
            // tabOne.setTextColor(Color.GREEN);
        }
    });

}

下面是Android中的代码自定义标签布局。

public class MainActivity extends AppCompatActivity {
    private TabLayout tabLayout;
    private ViewPager viewPager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        viewPager = (ViewPager) findViewById(R.id.viewpager);
        createViewPager(viewPager);

        tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(viewPager);
        createTabIcons();
    }
    private void createTabIcons() {

        TextView tabOne = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
        tabOne.setText("Tab 1");
        tabOne.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_dash26, 0, 0);
        tabLayout.getTabAt(0).setCustomView(tabOne);

        TextView tabTwo = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
        tabTwo.setText("Tab 2");
        tabTwo.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_category, 0, 0);
        tabLayout.getTabAt(1).setCustomView(tabTwo);

        TextView tabThree = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
        tabThree.setText("Tab 3");
        tabThree.setCompoundDrawablesWithIntrinsicBounds(0, R.drawable.ic_order, 0, 0);
        tabLayout.getTabAt(2).setCustomView(tabThree);
    }

    private void createViewPager(ViewPager viewPager) {
        ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
        adapter.addFrag(new Fragment1(), "Tab 1");
        adapter.addFrag(new Fragment2(), "Tab 2");
        adapter.addFrag(new Fragment3(), "Tab 3");
        viewPager.setAdapter(adapter);
    }

    class ViewPagerAdapter extends FragmentPagerAdapter {
        private final List<Fragment> mFragmentList = new ArrayList<>();
        private final List<String> mFragmentTitleList = new ArrayList<>();

        public ViewPagerAdapter(FragmentManager manager) {
            super(manager);
        }

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

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

        public void addFrag(Fragment fragment, String title) {
            mFragmentList.add(fragment);
            mFragmentTitleList.add(title);
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return mFragmentTitleList.get(position);
        }
    }
