直播系统app源码，TabLayout:自定义字体大小

直播系统app源码，TabLayout:自定义字体大小实现的相关代码

1、主代码

<br>//方式一：<br>    private String[] mTabs = new String[]{"案例", "宣传"};<br>//方式二：动态生成数据<br>private String[] mTabs = {};<br>private List<String> firstList = new ArrayList<>();<br>firstList.add("案例");<br>firstList.add("宣传");<br> mTabs = new String[firstList.size()];<br>firstList.toArray(mTabs);<br> <br> <br> <br>private void initTab() {<br>        addTab(tabLayout, position -> {<br>           <br> <br>        });<br> <br> <br>    }<br> <br>    private void addTab(TabLayout tabLayout, OnTabChangedListener listener) {<br>        for (String tab : mTabs) {<br>            tabLayout.addTab(tabLayout.newTab().setText(tab));<br>        }<br>        tabLayout.setScrollableTabRadius(5);<br>        tabLayout.setSelectedTabIndicatorWidth(70);<br>        tabLayout.setIndicatorVerticalOffset(0);<br>        tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {//改变选中状态下文字大小<br>            @Override<br>            public void onTabSelected(TabLayout.Tab tab) {<br>                setCustomTab(tab, true);<br>                if (listener != null) {<br>                    listener.onTabChanged(tab.getPosition());<br>                }<br>            }<br> <br>            @Override<br>            public void onTabUnselected(TabLayout.Tab tab) {<br>                setCustomTab(tab, false);<br>            }<br> <br>            @Override<br>            public void onTabReselected(TabLayout.Tab tab) {<br> <br>            }<br>        });<br>        TabLayout.Tab tab = tabLayout.getTabAt(0);<br>        if (tab != null) {<br>            setCustomTab(tab, true);<br>         <br> <br>        }<br>    }<br> <br> <br>    private void setCustomTab(TabLayout.Tab tab, boolean isSelected) {<br>        tab.setCustomView(null);<br>        int color = Color.parseColor("#999999");<br>        int size = 15;<br>        if (isSelected) {<br>            color = Color.parseColor("#333333");<br>            size = 18;<br>        }<br>        @SuppressLint("InflateParams") TextView textView = (TextView) LayoutInflater.from(context).inflate(R.layout.item_tab_text, null);<br>        textView.setTextSize(size);<br>        textView.setTextColor(color);<br>        textView.setText(tab.getText());<br>        tab.setCustomView(textView);<br>    }

2、自定义接口

<br>public interface OnTabChangedListener {<br>    void onTabChanged(int position);<br>}

3、xml

<br><com.x.common.widget.tablayout.TabLayout<br>        android:id="@+id/tl_title"<br>        android:layout_width="match_parent"<br>        android:layout_height="50dp"<br>        android:background="#ffffff"<br>        android:paddingTop="10dp"<br>        android:paddingBottom="6dp"<br>        app:tabGravity="center"<br>        app:tabIndicatorColor="@color/colorPrimary"<br>        app:tabIndicatorHeight="4dp"<br>        app:tabPaddingBottom="4dp"<br>        app:tabSelectedTextColor="@color/colorPrimary" /><br><com.x.common.widget.MyTextView xmlns:android="http://schemas.android.com/apk/res/android"<br>    xmlns:app="http://schemas.android.com/apk/res-auto"<br>    android:textSize="16sp"<br>    android:layout_gravity="center"<br>    android:gravity="center"<br>    android:textColor="@color/color_333"<br>    android:layout_width="wrap_content"<br>    app:tv_bottom_height="15dp"<br>    app:tv_bottom_width="20dp"<br>    android:layout_height="wrap_content"><br> <br></com.zswl.common.widget.MyTextView>

4、MyTextView

<br>@SuppressLint("AppCompatCustomView")<br>public class MyTextView extends AppCompatTextView {<br>    private float mLeftWidth;<br>    private float mLeftHeight;<br>    private float mTopWidth;<br>

public void setDrawableRight(@DrawableRes int drawableRight) {<br>        Drawable drawableEnd = getResources().getDrawable(drawableRight);<br>        int size = dip2px(getContext(), 10);<br>

5、自定义属性

<br> <declare-styleable name="MyTextView"><br>        <attr name="tv_left_width" format="dimension" /><br>        <attr name="tv_left_height" format="dimension" /><br>        <attr name="tv_top_width" format="dimension" /><br>        <attr name="tv_top_height" format="dimension" /><br>        <attr name="tv_right_width" format="dimension" /><br>        <attr name="tv_right_height" format="dimension" /><br>        <attr name="tv_bottom_width" format="dimension" /><br>        <attr name="tv_bottom_height" format="dimension" /><br>    </declare-styleable>
