问题描述

我下面的教程 https://www.youtube.com/watch?v=VVahIc8yENk 而我得到的错误

我使用的是Android Studio来写这个计划,我已经从API 11试过21,其中没有工作。

 公共类Tabtest扩展FragmentActivity实现ActionBar.TabListener {

    动作条动作条;
    @覆盖
    保护无效的onCreate(包savedInstanceState){
        super.onCreate(savedInstanceState);
        的setContentView(R.layout.activity_tab_test);

        动作条= getActionBar();
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

        ActionBar.Tab TAB1 = actionBar.newTab();
        tab1.setText(TAB1);
        tab1.setTabListener(本);

        ActionBar.Tab TAB2 = actionBar.newTab();
        tab2.setText(TAB2);
        tab2.setTabListener(本);

        ActionBar.Tab TAB3 = actionBar.newTab();
        tab3.setText(TAB3);
        tab3.setTabListener(本);

        ActionBar.Tab TAB4 = actionBar.newTab();
        tab4.setText(TAB4);
        tab4.setTabListener(本);

        actionBar.addTab(TAB1);
        actionBar.addTab(TAB2);
        actionBar.addTab(TAB3);
        actionBar.addTab(TAB4);
    }

    @覆盖
    公共无效onTabSelected(ActionBar.Tab选项卡,FragmentTransaction英尺){
        Log.d(VIVZ,onTabReselected在+位置+ tab.getPosition()+名+ tab.getText());
    }

    @覆盖
    公共无效onTabUnselected(ActionBar.Tab选项卡,FragmentTransaction英尺){
        Log.d(VIVZ,onTabReselected在+位置+ tab.getPosition()+名+ tab.getText());
    }

    @覆盖
    公共无效onTabReselected(ActionBar.Tab选项卡,FragmentTransaction英尺){
        Log.d(VIVZ,onTabReselected在+位置+ tab.getPosition()+名+ tab.getText());
    }
}
 

解决方案

我是按照YouTube的Vivz的例子,但在法德precated我不得不另谋出路。而不是添加标签的动作条试的:

修改您的适配器:

 公共类CollectionPagerAdapter扩展FragmentStatePagerAdapter {

    私有String []标题= {项目1,项目2,3项};

    公共CollectionPagerAdapter(FragmentManager FM){
        超(FM);
    }

    @覆盖
    公共片段的getItem(int i)以{
        开关(ⅰ){
          情况下0:
             返回新碎裂();
          情况1:
             返回新FragmentB();
          案例2:
             返回新FragmentC();
        }
        返回null;
    }

    @覆盖
    公众诠释getCount将(){
        返回titles.length;
    }

    @覆盖
    公共CharSequence的getPageTitle(INT位置){
        回到标题[位置]
    }
}
 

而在你想实现的选项卡尝试活性

 公共类Tabtest扩展ActionBarActivity {
@覆盖
保护无效的onCreate(包savedInstanceState){
    super.onCreate(savedInstanceState);
    的setContentView(R.layout.activity_tab_test);

    ViewPager寻呼机=(ViewPager)findViewById(R.id.your_view_pager);
    pager.setAdapter(新CollectionPagerAdapter(getSupportFragmentManager()));

    PagerSlidingTabStrip标签=(PagerSlidingTabStrip)findViewById(R.id.tabs);
    tabs.setViewPager(寻呼机);
}
 

现在,如果你想风格你的标签像谷歌Play商店与运动指标下的标签名称和移动,同时用户滚动编译这个库

 编译com.astuetz:pagerslidingtabstrip:1.0.1
 

和修改viewpager布局文件是这样的:

 <的LinearLayout
  //明显增加​​宽度和高度等necessery东西
  机器人:方向=垂直>

< com.astuetz.PagerSlidingTabStrip
    机器人:ID =@ + ID /标签
    机器人:layout_width =match_parent
    机器人:layout_height =48dip/>

< android.support.v4.view.ViewPager
    的xmlns:机器人=htt​​p://schemas.android.com/apk/res/android
    机器人:ID =@ + ID /寻呼机
    机器人:layout_width =match_parent
    机器人:layout_height =match_parent/>


< / LinearLayout中>
 

然后你会收到预期的效果。

希望它可以帮助!

I'm following the tutorial https://www.youtube.com/watch?v=VVahIc8yENk and I'm getting the error

I'm using Android Studio to write this program and I have tried from API 11 to 21 and none of them work.

public class Tabtest extends FragmentActivity implements ActionBar.TabListener {

    ActionBar actionBar;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tab_test);

        actionBar=getActionBar();
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

        ActionBar.Tab tab1=actionBar.newTab();
        tab1.setText("tab1");
        tab1.setTabListener(this);

        ActionBar.Tab tab2=actionBar.newTab();
        tab2.setText("tab2");
        tab2.setTabListener(this);

        ActionBar.Tab tab3=actionBar.newTab();
        tab3.setText("tab3");
        tab3.setTabListener(this);

        ActionBar.Tab tab4=actionBar.newTab();
        tab4.setText("tab4");
        tab4.setTabListener(this);

        actionBar.addTab(tab1);
        actionBar.addTab(tab2);
        actionBar.addTab(tab3);
        actionBar.addTab(tab4);
    }

    @Override
    public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) {
        Log.d("VIVZ", "onTabReselected at "+" position "+tab.getPosition()+" name "+tab.getText());
    }

    @Override
    public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft) {
        Log.d("VIVZ", "onTabReselected at "+" position "+tab.getPosition()+" name "+tab.getText());
    }

    @Override
    public void onTabReselected(ActionBar.Tab tab, FragmentTransaction ft) {
        Log.d("VIVZ", "onTabReselected at "+" position "+tab.getPosition()+" name "+tab.getText());
    }
}
解决方案

I was following Vivz example in youtube but when the method deprecated i had to find another way. Instead of adding tabs to the actionbar try:

Modify your adapter:

public class CollectionPagerAdapter extends FragmentStatePagerAdapter {

    private String[] titles = {"Item 1", "Item 2", "Item 3" };

    public CollectionPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int i) {
        switch(i){
          case 0:
             return new FragmentA();
          case 1:
             return new FragmentB();
          case 2:
             return new FragmentC();
        }
        return null;
    }

    @Override
    public int getCount() {
        return titles.length;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return titles[position];
    }
}

And in the activity that you would like to implement the tabs try

public class Tabtest extends ActionBarActivity{
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_tab_test);

    ViewPager pager = (ViewPager) findViewById(R.id.your_view_pager);
    pager.setAdapter(new CollectionPagerAdapter(getSupportFragmentManager()));

    PagerSlidingTabStrip tabs = (PagerSlidingTabStrip) findViewById(R.id.tabs);
    tabs.setViewPager(pager);
}

Now if you would like to style your tabs like Google Play store with a moving indicator under the tab name and move while the user scrolls compile this library

compile 'com.astuetz:pagerslidingtabstrip:1.0.1'

And modify your viewpager layout file like this:

<LinearLayout
  //obviously add width and height and other necessery stuff
  android:orientation="vertical">

<com.astuetz.PagerSlidingTabStrip
    android:id="@+id/tabs"
    android:layout_width="match_parent"
    android:layout_height="48dip" />

<android.support.v4.view.ViewPager
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />


</LinearLayout>

And then you are going to have the desired effect.

Hope it helps!!!
