我已经实现了带有三个选项卡的 ViewPager，每个选项卡只有图标，并且将显示为左对齐。我的预期输出是制表符的宽度等于空格。这是我必要的代码和屏幕截图。请指导我解决问题，在此先感谢。
JustTabActivity.Class
public class JustTabActivity extends AppCompatActivity {
private TabLayout tabLayout;
private ViewPager parent_viewpager;
ViewPagerAdapter pageAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.aaa_sms_layout);
parent_viewpager = (ViewPager) findViewById(R.id.parent_viewpager);
setupViewPager(parent_viewpager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(parent_viewpager);
tabLayout.setFillViewport(true);
parent_viewpager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(onTabSelectedListener(parent_viewpager));
setupTabIcons();
}
private void setupTabIcons() {
int[] tabIcons = {R.drawable.icon1,R.drawable.icon5,R.drawable.ic_settings };
tabLayout.getTabAt(0).setIcon(tabIcons[0]);
tabLayout.getTabAt(1).setIcon(tabIcons[1]);
tabLayout.getTabAt(2).setIcon(tabIcons[2]);
tabLayout.getTabAt(0).getIcon().setColorFilter(Color.parseColor("#018FFD"), PorterDuff.Mode.SRC_IN);
tabLayout.getTabAt(1).getIcon().setColorFilter(Color.WHITE, PorterDuff.Mode.SRC_IN);
tabLayout.getTabAt(2).getIcon().setColorFilter(Color.WHITE, PorterDuff.Mode.SRC_IN);
}
private void setupViewPager(ViewPager viewPager) {
pageAdapter = new ViewPagerAdapter(getSupportFragmentManager());
pageAdapter.addFrag(new fragment_home_new());
pageAdapter.addFrag(new fragment_userprofile());
pageAdapter.addFrag(new fragment_settings());
parent_viewpager.setAdapter(pageAdapter);
}
}
};
}
}
最佳答案
将layout.xml中的app:tabMode="scrollable"替换为app:tabMode="fixed"
关于android - TabLayout ViewPager 图标显示在 Android 的角落，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40758508/
