Question

我是Android的新手。我想创建一个显示带有固定标签的操作栏的应用程序。我已经达到了这个目的。问题是标签不适合同一视图。

这是我的主要活动：

 package com.pestana.pestana;


import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.view.MenuInflater;
import android.app.ActionBar;
import android.app.Fragment;


public class MainActivity extends Activity {
    // Declare Tab Variable
    ActionBar.Tab Tab1, Tab2, Tab3,Tab4;
    Fragment fragmentTab1 = new FragmentTab1();
    Fragment fragmentTab2 = new FragmentTab2();
    Fragment fragmentTab3 = new FragmentTab3();
    Fragment fragmentTab4 = new FragmentTab4();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ActionBar actionBar = getActionBar();

        // Hide Actionbar Icon
        //actionBar.setDisplayShowHomeEnabled(false);

        // Hide Actionbar Title
        //actionBar.setDisplayShowTitleEnabled(false);

        // Create Actionbar Tabs
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

        // Set Tab Icon and Titles
        Tab1 = actionBar.newTab().setIcon(R.drawable.tab1);
        Tab2 = actionBar.newTab().setText("Tab2");
        Tab3 = actionBar.newTab().setText("Tab3");
        Tab4 = actionBar.newTab().setText("Tab4");

        // Set Tab Listeners
        Tab1.setTabListener(new TabListener(fragmentTab1));
        Tab2.setTabListener(new TabListener(fragmentTab2));
        Tab3.setTabListener(new TabListener(fragmentTab3));
        Tab4.setTabListener(new TabListener(fragmentTab4));

        // Add tabs to actionbar
        actionBar.addTab(Tab1);
        actionBar.addTab(Tab2);
        actionBar.addTab(Tab3);
        actionBar.addTab(Tab4);
    }

    @Override public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.main, menu);
        return true; /** true -> el menú ya está visible */
     }
}

这就是布局

`

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/fragment_container"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" />

`

我还为FragmentTab1创建了4个类... FragmentTab4，

FragmentTab1

    package com.pestana.pestana;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.app.Fragment;

public class FragmentTab1 extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragmenttab1, container, false);
        return rootView;
    }

}

FragmentTab2

    package com.pestana.pestana;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.app.Fragment;

public class FragmentTab2 extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragmenttab2, container, false);
        return rootView;
    }

}

FragmentTab3

    package com.pestana.pestana;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.app.Fragment;

public class FragmentTab3 extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragmenttab3, container, false);
        return rootView;
    }

}

FragmentTab4

    package com.pestana.pestana;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.app.Fragment;

public class FragmentTab4 extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragmenttab4, container, false);
        return rootView;
    }

}

TabListener.java

    package com.pestana.pestana;


import android.app.ActionBar;
import android.app.ActionBar.Tab;
import android.app.Fragment;
import android.app.FragmentTransaction;

public class TabListener implements ActionBar.TabListener {

    Fragment fragment;

    public TabListener(Fragment fragment) {
        // TODO Auto-generated constructor stub
        this.fragment = fragment;
    }

    @Override
    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        // TODO Auto-generated method stub
        ft.replace(R.id.fragment_container, fragment);
    }

    @Override
    public void onTabUnselected(Tab tab, FragmentTransaction ft) {
        // TODO Auto-generated method stub
        ft.remove(fragment);
    }

    @Override
    public void onTabReselected(Tab tab, FragmentTransaction ft) {
        // TODO Auto-generated method stub

    }
}

每个片段的4个XML布局这是一个例子，只需要为每个XML更改Fragment1

    <?xml version="1.0" encoding="utf-8"?>
<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" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="@string/Fragment1" />

</RelativeLayout>

我被困了3天，有什么帮助吗？使用相同的代码，我可以使用不同的选项卡实现滑动视图吗？提前致谢

查看文档（Creating Swipe Views with Tabs），您可以下载一个如何完全按照自己的意愿行事的实例。

修复了同一视图中的选项卡
