我有以下课程:
public class MyFragment extends Fragment{
int mCurrentPage;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/** Getting the arguments to the Bundle object */
Bundle data = getArguments();
/** Getting integer data of the key current_page from the bundle */
mCurrentPage = data.getInt("current_page", 0);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.myfragment_layout, container,false);
TextView tv = (TextView ) v.findViewById(R.id.tv);
tv.setText("Você está no item " + mCurrentPage +" do menu"+ "\n\n" + "deslize para os lados para poder escolher a opção");
return v;
在oncreateview方法只调用布局的情况下,如何在每个paágina或滑动视图选项卡中将其称为布局(片段),主要用作菜单。
梨作为Bandle方法参与以下课程:
public class MyFragmentPagerAdapter extends FragmentPagerAdapter{
final int PAGE_COUNT = 5;
/** Constructor of the class */
public MyFragmentPagerAdapter(FragmentManager fm) {
super(fm);
}
/** This method will be invoked when a page is requested to create */
@Override
public Fragment getItem(int arg0) {
MyFragment myFragment = new MyFragment();
Bundle data = new Bundle();
data.putInt("current_page", arg0+1);
myFragment.setArguments(data);
return myFragment;
}
/** Returns the number of pages */
@Override
public int getCount() {
return PAGE_COUNT;
}
@Override
public CharSequence getPageTitle(int position) {
return "Pag" + ( position + 1 );
}
主要看起来像这样:
public class MainActivity extends FragmentActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
/** Obtendo uma referência ao ViewPager definido o arquivo de layout */
ViewPager pager = (ViewPager) findViewById(R.id.pager);
/** Obtendo gerente fragmento */
FragmentManager fm = getSupportFragmentManager();
/** instanciando FragmentPagerAdapter */
MyFragmentPagerAdapter pagerAdapter = new MyFragmentPagerAdapter(fm);
/** definindo o pagerAdapter ao objeto pager */
pager.setAdapter(pagerAdapter);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
和/或xml main_activity:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<android.support.v4.view.PagerTabStrip
android:id="@+id/pager_tab_strip"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:background="#33b5e5"
android:paddingBottom="4dp"
android:paddingTop="4dp"
android:textColor="#fff" />
</android.support.v4.view.ViewPager>
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="46dp"
android:text="Menu Principal"
android:textColor="#1E90FF"
android:textStyle="bold"
android:typeface="sans"
android:textSize="25sp" />
</RelativeLayout>
和myfragment.xml:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
>
</TextView>
请给我发送代码,这些代码可以考虑我的目标来绘制几个布局!
