我是Android的新手,我正在尝试实现滑动菜单,因此我按照一些教程进行了操作,最后得到了这些代码:
的活动:
public class MercadoriaFormActivity extends AbstractActivity {
@Inject
MercadoriaService mercadoriaService;
@InjectView(R.id.toolbarMercadoria)
Toolbar toolbar;
@InjectView(R.id.pagerMercadoriaForm)
ViewPager pager;
@InjectView(R.id.tabsMercadoria)
SlidingTabLayout tabs;
private MercadoriaFragmentPageAdapter adapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_form_mercadoria);
setSupportActionBar(toolbar);
adapter = new MercadoriaFragmentPageAdapter(getSupportFragmentManager());
pager.setAdapter(adapter);
tabs.setDistributeEvenly(true);
tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
@Override
public int getIndicatorColor(int position) {
return getResources().getColor(R.color.primary_dark);
}
});
tabs.setViewPager(pager);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_mercadoria_form, menu);
return true;
}
}
我的布局:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include
android:id="@+id/toolbarMercadoria"
layout="@layout/toolbar_default"
android:layout_height="wrap_content"
android:layout_width="match_parent"
/>
<foxy.com.br.mobile.controller.widget.SlidingTabLayout
android:id="@+id/tabsMercadoria"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="2dp"
android:background="@color/primary"/>
<android.support.v4.view.ViewPager
android:id="@+id/pagerMercadoriaForm"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>
</LinearLayout>
我的适配器:
public class MercadoriaFragmentPageAdapter extends FragmentPagerAdapter {
private static final int PAGES_NUMBER = 2;
private MercadoriaFormFragment mercadoriFormFragment;
private MercadoriaAvaliacoesSensoriaisFragment avaliacoesSensoriaisFragment;
public MercadoriaFragmentPageAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
if (position == 0) {
return getMercadoriFormFragment();
}
if (position == 1) {
return getAvaliacoesSensoriaisFragment();
}
return null;
}
@Override
public int getCount() {
return PAGES_NUMBER;
}
@Override
public CharSequence getPageTitle(int position) {
if (position == 0) {
return "Dados";
}
if (position == 1) {
return "A. Sensoriais";
}
return null;
}
public MercadoriaAvaliacoesSensoriaisFragment getAvaliacoesSensoriaisFragment() {
if (avaliacoesSensoriaisFragment == null)
avaliacoesSensoriaisFragment = new MercadoriaAvaliacoesSensoriaisFragment();
return avaliacoesSensoriaisFragment;
}
public MercadoriaFormFragment getMercadoriFormFragment() {
if (mercadoriFormFragment == null)
mercadoriFormFragment = mercadoriFormFragment.newInstance();
return mercadoriFormFragment;
}
}
但我的标签不会显示。我不知道我错过了什么,所以我最终得到了这个屏幕:
我真的可以使用一些帮助:B,如果我能提供任何额外的信息,请告诉我。

你没有正确使用Butterknife。在onCreate()方法中,添加@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_form_mercadoria);
// Add the following
ButterKnife.inject(this);
setSupportActionBar(toolbar);
adapter = new MercadoriaFragmentPageAdapter(getSupportFragmentManager());
pager.setAdapter(adapter);
tabs.setDistributeEvenly(true);
tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
@Override
public int getIndicatorColor(int position) {
return getResources().getColor(R.color.primary_dark);
}
});
tabs.setViewPager(pager);
}
。
schema: {
data: "ranks"
},

你试过尺码玩吗?匹配父项从父项获取所有维度,似乎从屏幕中取出。尝试使用“Xdp”,其中X放置一个数值并检查出来。

我发现了我的问题,在我的问题中没有清楚,因为我没有发布AbstractActivity类,我已经调用了setContent方法,所以问题是我调用了setContent两次.. 谢谢你的帮助。
