以下是代码,按照以下步骤执行:
1)为活动创建布局:
<RelativeLayout android:id="@+id/job_layout"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:materialdesign="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="56dp"/>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@id/toolbar">
<com.xlsys.generic.view.SlidingTabLayout
android:id="@+id/sliding_tabs1"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<android.support.v4.view.ViewPager
android:id="@+id/pager1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/sliding_tabs1"
/>
</RelativeLayout>
</RelativeLayout>
2) Create two fragment for two tab if three Tab then create three fragment:
Fragment 1)
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.xlsys.generic.activities.R;
public class JobCalender extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View mView = inflater.inflate(R.layout.inspection, container, false);
return mView;
}
}
3) Create xml file for above fragment
3) Same way create another fragment and xml file for another tab.
4) Create Activity :
import android.os.Bundle;
import android.support.v4.app.FragmentStatePagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.Fragment;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import com.xlsys.generic.fragments.Inspection_Fragment;
import com.xlsys.generic.fragments.NC_Fragments;
import com.xlsys.generic.view.SlidingTabLayout;
import android.support.design.widget.TabLayout;
import android.widget.LinearLayout;
import android.widget.TextView;
public class AddLocationActivity extends AppCompatActivity {
private String mPagerItem[]={"Calender","Tab2"};
private Toolbar toolbar;
private SlidingTabLayout mSlidingTabLayout;
ViewPager pager;
public String jobId,mTaskType,taskCreatedDate;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.addlocation);
getWidgets();
setWidgets();
setWidgetsListener();
}
private void getWidgets()
pager = (ViewPager) findViewById(R.id.pager1);
mSlidingTabLayout = (SlidingTabLayout)findViewById(R.id.sliding_tabs1);
}
private void setWidgets()
{
pager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));
mSlidingTabLayout.setViewPager(pager);
}
private class MyPagerAdapter extends FragmentStatePagerAdapter {
int mNumOfTabs;
public MyPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public CharSequence getPageTitle(int position) {
return mPagerItem[position];
}
public Fragment getItem(int pos) {
switch(pos) {
case 0:
JobCalender JobCalender_fragment=new JobCalender();
return JobCalender_fragment;
case 1:
NC_Fragments mNC_Fragments=new NC_Fragments();
return mNC_Fragments;
default:
JobCalender JobCalender_fragment=new JobCalender();
return JobCalender_fragment;
}
}
public int getCount() {
return mPagerItem.length;
}
}
}
5) 添加 SlidingTabLayout 类:
