在我的android應用程序中有一個swipeable tab佈局。它有兩個選項卡:新投訴和先前的投訴。當點擊抱怨標籤時,我需要啓動NewComplain.java。這裏是我NewComplain類代碼段:Android:在swipeable tab佈局中切換活動
NewComplain類
public class NewComplain extends SherlockFragmentActivity implements View.OnClickListener {
private int Year;
private int Month;
private int Day;
private static final int DATE_DIALOG_ID = 1;
private View viewLoad;
private TextView heading, date;
private Spinner spiComplain, spiProduct;
private EditText description, contInfo;
private Button btnDate;
private ArrayAdapter<String> complainAdapter, prodAdapter;
private ArrayList<String> lstComplain = new ArrayList<String>();
private ArrayList<String> lstProdNames = new ArrayList<String>();
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
viewLoad = LayoutInflater.from(NewComplain.this).inflate(
R.layout.new_complain, null);
setContentView(viewLoad);
}
}
這個id我TabsPagerAdapter類。
package xont.virtusel.v4.controller.sale;
import android.content.Intent;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class TabsPagerAdapter extends FragmentPagerAdapter {
public TabsPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int index) {
switch (index) {
case 0:
case 1:
}
return null;
}
@Override
public int getCount() {
// get item count - equal to number of tabs
return 2;
}
}
這是我主要活動類。
package xont.virtusel.v4.controller.sale;
import xont.virtusel.v4.controller.R;
import android.app.ActionBar;
import android.app.ActionBar.Tab;
import android.app.FragmentTransaction;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.view.ViewPager;
public class CustomerComplainActivity extends FragmentActivity implements ActionBar.TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
private String[] tabs = { "New Complain", "Previous Complains" };
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initialization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setDisplayHomeAsUpEnabled(true);
//actionBar.setHomeButtonEnabled(true);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
//actionBar.setDisplayShowHomeEnabled(false);
//actionBar.setDisplayShowTitleEnabled(false);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
@Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
@Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
}
@Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// on tab selected
// show respected fragment view
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
}
}
如何將切換活動語句添加到此TabsPagerAdapter類中。我用意圖。但它沒有奏效。 任何人都可以這麼友好地澄清這個問題。 Thanx提前
