为保证android2.0以上均能运行，使用support.v7库下的actionbar及fragment继承自AppCompatActivity（ActionBarActivity已过时）使用getSupportActionBar()得到ActionBar，ActionBar.Tab，这里Tab必须设置监听，在监听中实现Fragment的切换。
这里重点提一下，Theme主题一定要适配，因为我使用的是AppCompatActivity，后面自定义主题。
1、main.xml
<?xml version="1.0" encoding="utf-8"?> <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> <FrameLayout android:id="@+id/context" android:layout_width="match_parent" android:layout_height="match_parent"/> </android.support.constraint.ConstraintLayout>
2、MainActivity
package com.example.call_aidl_for_rfid_as; import android.os.Bundle; import android.support.design.widget.FloatingActionButton; import android.support.design.widget.Snackbar; import android.support.v4.app.FragmentTransaction; import android.support.v7.app.ActionBar; import android.support.v7.app.AppCompatActivity; import android.support.v7.widget.Toolbar; import android.util.Log; import android.view.KeyEvent; import android.view.View; public class Main2Activity extends AppCompatActivity { ActionBar actionBar; BaseFragment curFragment; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main2); actionBar = getSupportActionBar(); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); ActionBar.Tab tab1 = actionBar.newTab(); tab1.setText("新业务Service"); tab1.setTabListener(new MyTabListener(new NewBusinessServiceFragment())); ActionBar.Tab tab2 = actionBar.newTab().setText("盘点Service"); tab2.setTabListener(new MyTabListener(new InventoryServiceFragment())); actionBar.addTab(tab1); actionBar.addTab(tab2); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) {return curFragment.onKeyDown(keyCode,event); } class MyTabListener implements ActionBar.TabListener{ private BaseFragment fragment; public MyTabListener (BaseFragment fragment){ this.fragment=fragment; } @Override public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) { curFragment = fragment; ft.replace(R.id.context,fragment); } @Override public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft) { } @Override public void onTabReselected(ActionBar.Tab tab, FragmentTransaction ft) { } } @Override protected void onDestroy() { super.onDestroy(); } }
3、BaseFragement.class 用于处理KeyDown事件
package com.example.rfid_sdk_as; import android.support.v4.app.Fragment; import android.util.Log; import android.view.KeyEvent; public class BaseFragment extends Fragment{ //这里的是我们的重点 public boolean onKeyDown(int keyCode, KeyEvent event){return false; } }
4、NewBusinessServiceFragment
public class NewBusinessServiceFragment extends BaseFragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.fragment_fragment_new_business, container, false); } @Override public void onActivityCreated(@Nullable Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); View view = getView(); context = view.getContext(); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { // TODO Auto-generated method stub if (keyCode == 280 || keyCode == 139) { } return super.onKeyDown(keyCode, event); } }
5、InventoryServiceFragment
public class NewBusinessServiceFragment extends BaseFragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.fragment_inventory, container, false); } @Override public void onActivityCreated(@Nullable Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); View view = getView(); context = view.getContext(); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { // TODO Auto-generated method stub if (keyCode == 280 || keyCode == 139) { } return super.onKeyDown(keyCode, event); } }
6、AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.rfid_sdk_as"> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:roundIcon="@mipmap/ic_launcher_round" android:supportsRtl="true" android:theme="@style/CustomActionBarTheme"> <activity android:name=".Main2Activity" android:windowSoftInputMode="adjustPan"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".MainActivity" android:windowSoftInputMode="adjustPan"> </activity> </application> </manifest>
7、配置CustomActionBarTheme主题，在values目录下的style.xml文件中添加如下：
<style name="CustomActionBarTheme" parent="@style/Theme.AppCompat.Light"> <item name="android:actionBarStyle">@style/MyActionBar</item> <item name="android:actionBarDivider">@null</item> <item name="android:actionBarTabTextStyle">@style/MyActionBarTabText</item> <!-- <item name="android:actionBarTabStyle">@style/MyActionBarTabs</item> --> <item name="android:actionBarTabBarStyle">@style/MyActionBarTabBars</item> <item name="android:actionMenuTextColor">@android:color/holo_green_light</item> <!-- Support library compatibility --> <item name="actionBarStyle">@style/MyActionBar</item> <item name="actionBarDivider">@null</item> <item name="actionBarTabTextStyle">@style/MyActionBarTabText</item> <!-- <item name="actionBarTabStyle">@style/MyActionBarTabs</item> --> <item name="actionBarTabBarStyle">@style/MyActionBarTabBars</item> <item name="actionMenuTextColor">@android:color/holo_green_light</item> </style> <!-- ActionBar styles --> <style name="MyActionBar" parent="@style/Widget.AppCompat.ActionBar"> <!--<item name="android:background">@android:color/holo_orange_light</item>--> <item name="android:titleTextStyle">@style/MyActionBarTitleText</item> <item name="android:backgroundStacked">@color/colorWhite</item> <!-- Support library compatibility --> <item name="background">@color/colorPrimary</item> <item name="titleTextStyle">@style/MyActionBarTitleText</item> <item name="backgroundStacked">@color/colorWhite</item> </style> <!-- ActionBar title text --> <style name="MyActionBarTitleText" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"> <item name="android:textColor">@color/colorWhite</item> </style> <!-- ActionBar tabs text --> <style name="MyActionBarTabText" parent="@style/Widget.AppCompat.ActionBar.TabText"> <item name="android:textColor">@android:color/holo_blue_bright</item> </style> <style name="MyActionBarTabBars" parent="@style/Widget.AppCompat.ActionBar.TabBar"> <item name="android:showDividers">none</item> </style>
