我已按照这些教程来解决此问题。

但是,在尝试了几种解决方案后,这个问题仍然存在,这很烦人。这是我面临的问题的演示。自从我在这个问题上陷入困境以来已经有好几周了。
演示链接。
我用于测试的设备是Nexus 4和Nexus 5。
TabLayout
与不是滚动平滑。我需要滑动两次才能在下次点击时切换。我环顾了一下网络,但找不到任何解决方案。我正在使用最新的支持设计库。这是 gradle 文件ViewPager
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.softoven.ultron"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.3.0'
compile 'com.android.support:design:23.3.0'

compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'
compile 'com.google.code.gson:gson:2.5'
}
这是活动代码。
private DrawerLayout drawerLayout;
private ViewPager viewPager;
private TabLayout tabLayout;
private NavigationView navigationView;
private CategoriesDTO categoriesDTO;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initToolbar();
initUi();
loadCategories();
}
private void initToolbar() {
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_action_menu);
}
private void initUi() {
drawerLayout = (DrawerLayout) findViewById(R.id.drawer);
navigationView = (NavigationView) findViewById(R.id.navigation);
viewPager = (ViewPager) findViewById(R.id.viewPager);
tabLayout = (TabLayout) findViewById(R.id.tab);
}
private void loadCategories() {
StringRequest request = new StringRequest(Constants.URL_GET_CATEGORIES, new Response.Listener<String>() {
@Override
public void onResponse(String response) {
categoriesDTO = Constants.gson.fromJson(response, CategoriesDTO.class);
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
viewPager.setOffscreenPageLimit(1);
viewPager.setAdapter(adapter);
setTabLayout();
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
});
ApplicationController.getmInstance().addToRequestQueue(request);
}
private void setTabLayout() {
tabLayout.setupWithViewPager(viewPager);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.menu.home_side_menu, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
switch (id) {
case android.R.id.home:
drawerLayout.openDrawer(GravityCompat.START);
return true;
}
return super.onOptionsItemSelected(item);
}
private class ViewPagerAdapter extends FragmentPagerAdapter {
public ViewPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
return new ContentFragment();
}
@Override
public int getCount() {
return 10;
}
@Override
public CharSequence getPageTitle(int position) {
String title = categoriesDTO.getCategories().get(position).getTitle();
return (CharSequence) title;
}
}
和 xml 文件
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout

android:layout_width="match_parent"
android:layout_height="wrap_content">

<android.support.design.widget.TabLayout

android:layout_height="wrap_content"

这是你可以看到指标被部分分割的屏幕截图。
任何解决方案?
