Question

我正在尝试使用标签创建应用，但我收到错误..请帮助..

当我使用'ActionBar actionBar'并在此行代码中出错时：
actionBar = getActionBar(); -> incompatible type。
当我使用 android.app.ActionBar actionBar时，我在此行收到错误：

actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); -> error
        for (int i = 0; i < 3; i++) {
            actionBar.addTab(actionBar.newTab().setText(tabNames[i])
                    .setTabListener(this)); -> error
        }



app module :<br>
    android {
        compileSdkVersion 23
        buildToolsVersion "22.0.1"


        defaultConfig {
            useLibrary 'org.apache.http.legacy'
            minSdkVersion 21
            targetSdkVersion 23
            versionCode 1
            versionName "1.0"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
        }
}

tabActivity

import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
import android.support.v4.view.ViewPager;
import android.support.v7.app.ActionBar;
import android.os.Bundle;


public class tabActivity extends FragmentActivity implements ActionBar.TabListener {

    private ViewPager viewPager;
    private TabsPagerAdapter tabPagerAdapter;
    private android.app.ActionBar actionBar;
    private String[] tabNames = { "First", "Second"};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tabActivity);
        viewPager = (ViewPager) findViewById(R.id.pager);
        tabPagerAdapter = new TabsPagerAdapter(getSupportFragmentManager());
        viewPager.setAdapter(tabPagerAdapter);
        actionBar = getActionBar();
        actionBar.setHomeButtonEnabled(true);
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
        for (int i = 0; i < 3; i++) {
            actionBar.addTab(actionBar.newTab().setText(tabNames[i])
                    .setTabListener(this));
        }
        viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
            @Override
            public void onPageSelected(int postion) {
                actionBar.setSelectedNavigationItem(postion);
            }
            @Override
            public void onPageScrolled(int arg0, float arg1, int arg2) {
            }
            @Override
            public void onPageScrollStateChanged(int arg0) {
            }
        });
    }
    @Override
    public void onTabReselected(ActionBar.Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
    }
    @Override
    public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) {
        viewPager.setCurrentItem(tab.getPosition());
    }
    @Override
    public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
    }
}

Answer 1

而不是FragmentActivity尝试延长AppCompatActivity而不是getActionBar()使用getSupportActionBar()

Answer 2

如果你想要Tab，你可以试试这个。

TabHost th = getTabHost();

        //Tab 1
        TabSpec tab1= th.newTabSpec("Tab Name");
        tab1.setIndicator("Frame Anim", getResources().getDrawable(R.drawable.ic));
        Intent move = new Intent(getApplicationContext(), FrameAnimation.class);
        tab1.setContent(move);
        //Tab 2
        TabSpec tab2= th.newTabSpec("Tab Name");
        tab2.setIndicator("Tween Amin", getResources().getDrawable(R.drawable.ic));
        Intent movetween = new Intent(getApplicationContext(), TweenAnimations.class);
        tab2.setContent(movetween); 
        th.addTab(tab1);
        th.addTab(tab2);

并在布局文件中添加TabHost。

android.support.v7.app.ActionBar＆amp; android.app.ActionBar
