我是Android新手。我想創建一個應用程序,顯示帶有固定選項卡的操作欄。我已經做到了。 問題在於選項卡不適合相同的視圖。固定標籤在同一視圖
這是我的主要活動:
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 */
}
}
這是佈局
`
<?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" />
`
我還創建了4類FragmentTab1 .. 。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
0123每個片段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
}
}
4 XML佈局,這是一個例子,只需要改變片段1每個XML
<?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,任何幫助,請?使用相同的代碼,我可以使用不同的選項卡實施滑動視圖?在此先感謝
這是什麼意思'問題是標籤不適合相同的視圖'? – GrIsHu
如果你想用不同的選項卡實現Swipe視圖,那麼你可以去'ViewPager'。 – GrIsHu
