android 字体选中加粗,Android TabLayout选中字体加粗

解决办法是为TabLayout 添加一个监听,并在监听中自定义选中项UI,代码和布局文件如下

tablayoutTablayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {

@Override

public void onTabSelected(TabLayout.Tab tab) {

View view = tab.getCustomView();

if (null == view) {

tab.setCustomView(R.layout.custom_tab_layout_text);

}

TextView textView = tab.getCustomView().findViewById(android.R.id.text1);

textView.setTextColor(tablayoutTablayout.getTabTextColors());

textView.setTypeface(Typeface.DEFAULT_BOLD);

}

@Override

public void onTabUnselected(TabLayout.Tab tab) {

View view = tab.getCustomView();

if (null == view) {

tab.setCustomView(R.layout.custom_tab_layout_text);

}

TextView textView = tab.getCustomView().findViewById(android.R.id.text1);

textView.setTypeface(Typeface.DEFAULT);

}

@Override

public void onTabReselected(TabLayout.Tab tab) {

}

});

用到的布局文件如下

android:id="@android:id/text1"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:gravity="center"

/>

如果需要联合使用Fragment

需要注意的是 监听一定要在setupWithViewPager方法之前添加,否则会有bug
