Android的充气的标签视图浏览 [英] Android Inflating Views of Tab View
本文介绍了Android的充气的标签视图浏览的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我要实现我的应用程序这个功能，如下图所示。
- 在用行动吧和行动项目活动
- 标签下面的动作条
- 在每个选项卡中都会有内容的。
我用Tab键片段和TabListeners至code。现在，当我运行的应用程序，我收到标签观点，但认为寻呼机和指标缺失。我得到一个活动，如下图所示。
我的code为如下图所示。
TabViewActivity的.java
公共类TabViewActivity扩展SherlockFragmentActivity {
公共无效的onCreate（包savedInstanceState）{
super.onCreate（savedInstanceState）;
copyPrivateRawResuorceToPubliclyAccessibleFile（）;
动作条动作条= getSupportActionBar（）;
actionBar.setNavigationMode（ActionBar.NAVIGATION_MODE_TABS）;
//添加标签
标签TAB1 =动作条
。新标签（）
.setText（细则）
.setTabListener（
新TabListener＆LT; TabFragment＆GT;（这一点，TAB1
TabFragment.class））;
actionBar.addTab（TAB1）;
标签TAB2 =动作条
。新标签（）
.setText（地图）
.setTabListener（
新TabListener＆LT; TabFragment＆GT;（这一点，TAB2
TabFragment.class））;
actionBar.addTab（TAB2）;
//检查是否有一个保存的状态来选择活动标签
如果（savedInstanceState！= NULL）{
getSupportActionBar（）。setSelectedNavigationItem（
savedInstanceState.getInt（ACTIVE_TAB））;
}
}
TabListener.java
公共类TabListener＆LT;吨延伸SherlockFragment＆GT;器物
ActionBar.TabListener {
私人SherlockFragment mFragment;
私人最终SherlockFragmentActivity mActivity;
私人最终字符串MTAG;
私人最终类别＆LT; T＆GT; mClass;
公共TabListener（活动活动，字符串变量，类＆LT; T＆GT; CLZ）{
mActivity =（SherlockFragmentActivity）的活动;
MTAG =标签;
mClass = CLZ;
}
公共无效onTabSelected（TAB键，FragmentTransaction英尺）{
//检查片段已经被初始化
SherlockFragment preInitializedFragment =（SherlockFragment）mActivity
。.getSupportFragmentManager（）findFragmentByTag（MTAG）;
如果（mFragment！= NULL）{
//如果它存在，只需将它为了显示它
ft.attach（mFragment）;
}否则，如果（preInitializedFragment！= NULL）{
mFragment = preInitializedFragment;
ft.attach（mFragment）;
} 其他 {
//未找到，所以实例化并把它添加到活动
mFragment =（SherlockFragment）SherlockFragment.instantiate（
mActivity，mClass.getName（））;
ft.add（android.R.id.content，mFragment，MTAG）;
}
}
公共无效onTabUnselected（TAB键，FragmentTransaction英尺）{
如果（mFragment！= NULL）{
//分离的片段，因为另一个被连接
ft.detach（mFragment）;
}
}
公共无效onTabReselected（TAB键，FragmentTransaction英尺）{
//用户选择已经选择的选项卡。通常什么也不做。
}
TabFragment.java
公共类TabFragment扩展SherlockFragment {
//您的会员在这里变量
@覆盖
公共查看onCreateView（LayoutInflater充气，
ViewGroup中的容器，包savedInstanceState）{
//充气的布局该片段
查看查看= inflater.inflate（R.layout.main，集装箱，假）;
//做你的看法初始化这里
返回查看;
}
}
我有两个不同的类别对每个选项卡中单击命名details.java和maps.java。 请帮我在这里把这个code。 我还实施视图寻呼机。这是我的看法呼机code的详细信息选项卡。
DetailsActivity.java
公共类DetailsActivity扩展BaseSampleActivity {
@覆盖
保护无效的onCreate（包savedInstanceState）{
super.onCreate（savedInstanceState）;
的setContentView（R.layout.place_details_layout）;
mAdapter =新TestFragmentAdapter（getSupportFragmentManager（））;
mPager =（ViewPager）findViewById（R.id.pager）;
mPager.setAdapter（mAdapter）;
mIndicator =（CirclePageIndicator）findViewById（R.id.indicator）;
mIndicator.setViewPager（mPager）;
}
}
BaseSampleActivity.java
公共抽象类BaseSampleActivity扩展FragmentActivity {
私有静态最后随机RANDOM =新的随机（）;
TestFragmentAdapter mAdapter;
ViewPager mPager;
PageIndicator mIndicator;
// FragmentTabHost mTabHost;
@覆盖
公共布尔onCreateOptionsMenu（菜单菜单）
{
。getMenuInflater（）膨胀（R.menu.main，菜单）;
返回true;
}
@覆盖
公共布尔onOptionsItemSelected（菜单项项）{
开关（item.getItemId（））{
案例R.id.random：
最终诠释页= RANDOM.nextInt（mAdapter.getCount（））;
Toast.makeText（这一点，更改到页面+页，Toast.LENGTH_SHORT）;
mPager.setCurrentItem（页）;
返回true;
案例R.id.add_page：
如果（mAdapter.getCount（）小于10）{
mAdapter.setCount（mAdapter.getCount（）+ 1）;
mIndicator.notifyDataSetChanged（）;
}
返回true;
案例R.id.remove_page：
如果（mAdapter.getCount（）→1）{
mAdapter.setCount（mAdapter.getCount（） - 1）;
mIndicator.notifyDataSetChanged（）;
}
返回true;
}
返回super.onOptionsItemSelected（项目）;
}
}
解决方案
我没有看到任何code在那里为 ViewPager ，检查出的例子从杰克沃顿code <一个href="https://github.com/JakeWharton/ActionBarSherlock/blob/master/samples/fragments/src/com/actionbarsherlock/sample/fragments/FragmentTabsPager.java"相对=nofollow> FragmentTabsPager
I want to implement this feature in my app as shown below.
- Activity with Action bar and Action Items
- Tabs Below the actionbar
- Each of the Tabs will have content.
I used Tab fragments and TabListeners to code. Now when i run the app i am getting tab view but the view pager and indicator are missing. i am getting an activity as shown below.
My code is as shown below.
TabViewActivity .java
public class TabViewActivity extends SherlockFragmentActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
copyPrivateRawResuorceToPubliclyAccessibleFile();
ActionBar actionBar = getSupportActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// add tabs
Tab tab1 = actionBar
.newTab()
.setText("Details")
.setTabListener(
new TabListener<TabFragment>(this, "tab1",
TabFragment.class));
actionBar.addTab(tab1);
Tab tab2 = actionBar
.newTab()
.setText("Maps")
.setTabListener(
new TabListener<TabFragment>(this, "tab2",
TabFragment.class));
actionBar.addTab(tab2);
// check if there is a saved state to select active tab
if (savedInstanceState != null) {
getSupportActionBar().setSelectedNavigationItem(
savedInstanceState.getInt(ACTIVE_TAB));
}
}
TabListener.java
public class TabListener<T extends SherlockFragment> implements
ActionBar.TabListener {
private SherlockFragment mFragment;
private final SherlockFragmentActivity mActivity;
private final String mTag;
private final Class<T> mClass;
public TabListener(Activity activity, String tag, Class<T> clz) {
mActivity = (SherlockFragmentActivity) activity;
mTag = tag;
mClass = clz;
}
public void onTabSelected(Tab tab, FragmentTransaction ft) {
// Check if the fragment has already been initialised
SherlockFragment preInitializedFragment = (SherlockFragment) mActivity
.getSupportFragmentManager().findFragmentByTag(mTag);
if (mFragment != null) {
// If it exists, simply attach it in order to show it
ft.attach(mFragment);
} else if (preInitializedFragment != null) {
mFragment = preInitializedFragment;
ft.attach(mFragment);
} else {
// Not found, so instantiate and add it to the activity
mFragment = (SherlockFragment) SherlockFragment.instantiate(
mActivity, mClass.getName());
ft.add(android.R.id.content, mFragment, mTag);
}
}
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
if (mFragment != null) {
// Detach the fragment, because another one is being attached
ft.detach(mFragment);
}
}
public void onTabReselected(Tab tab, FragmentTransaction ft) {
// User selected the already selected tab. Usually do nothing.
}
TabFragment.java
public class TabFragment extends SherlockFragment {
// your member variables here
@Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container, Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.main, container, false);
// do your view initialization here
return view;
}
}
I have two different classes for each tab click named details.java and maps.java. please help me where to place this code. I have also implemented view pager. this is my view pager code for details tab.
DetailsActivity.java
public class DetailsActivity extends BaseSampleActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.place_details_layout);
mAdapter = new TestFragmentAdapter(getSupportFragmentManager());
mPager = (ViewPager)findViewById(R.id.pager);
mPager.setAdapter(mAdapter);
mIndicator = (CirclePageIndicator)findViewById(R.id.indicator);
mIndicator.setViewPager(mPager);
}
}
BaseSampleActivity.java
public abstract class BaseSampleActivity extends FragmentActivity {
private static final Random RANDOM = new Random();
TestFragmentAdapter mAdapter;
ViewPager mPager;
PageIndicator mIndicator;
//FragmentTabHost mTabHost;
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.random:
final int page = RANDOM.nextInt(mAdapter.getCount());
Toast.makeText(this, "Changing to page " + page, Toast.LENGTH_SHORT);
mPager.setCurrentItem(page);
return true;
case R.id.add_page:
if (mAdapter.getCount() < 10) {
mAdapter.setCount(mAdapter.getCount() + 1);
mIndicator.notifyDataSetChanged();
}
return true;
case R.id.remove_page:
if (mAdapter.getCount() > 1) {
mAdapter.setCount(mAdapter.getCount() - 1);
mIndicator.notifyDataSetChanged();
}
return true;
}
return super.onOptionsItemSelected(item);
}
}
解决方案
I don't see any code in there for a ViewPager, check out the example code from Jake Wharton's FragmentTabsPager
