Android - 将搜索传递给片段 _Android

最是人间留不住，朱颜辞镜花辞树。这篇文章主要讲述Android - 将搜索传递给片段相关的知识，希望能为你提供帮助。
所以我有一个带有标签（4）的应用程序，每个标签都有自己的布局和类文件。我还在操作栏中有一个searchview小部件。
我试图做的是允许用户搜索某些内容，将其作为字符串获取然后将其发送到片段，以便我可以使用该字符串并在将其用于查询后更新UI。
目前我有它，以便用户输入文本，一个类处理意图等等，然后我在片段类中获取我需要它的变量。
但是，当我在搜索视图中输入内容并按Enter键时，会弹出一个新窗口，但屏幕为空白。没有标签。没有搜索查看。
当然我做错了什么。有没有人有我可以提出的建议或改变？
main activity.java

public class MainActivity extends FragmentActivity implements ActionBar.TabListener {private ViewPager viewPager; private TabsPagerAdapter mAdapter; private ActionBar actionBar; // Tab titles private String[] tabs = { "Home", "Most Recent", "Followed", "All Items" }; public String test = "test"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Initilization viewPager = (ViewPager) findViewById(R.id.pager); actionBar = getActionBar(); mAdapter = new TabsPagerAdapter(getSupportFragmentManager()); viewPager.setAdapter(mAdapter); actionBar.setHomeButtonEnabled(false); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); // Adding Tabs for (String tab_name : tabs) { actionBar.addTab(actionBar.newTab().setText(tab_name).setTabListener(this)); }viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {@Override public void onPageSelected(int position) { // on changing the page // make respected tab selected actionBar.setSelectedNavigationItem(position); }@Override public void onPageScrolled(int arg0, float arg1, int arg2) {}@Override public void onPageScrollStateChanged(int arg0) {} }); }@Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.activity_main_actions, menu); SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE); SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView(); searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName())); return super.onCreateOptionsMenu(menu); }@Override public void onTabReselected(Tab tab, FragmentTransaction ft) {}@Override public void onTabSelected(Tab tab, FragmentTransaction ft) { // on tab selected // show respected fragment view viewPager.setCurrentItem(tab.getPosition()); }@Override public void onTabUnselected(Tab tab, FragmentTransaction ft) {}}

search results activity.Java

public class SearchResultsActivity extends Activity { public String query = ""; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); ActionBar actionBar = getActionBar(); actionBar.setDisplayHomeAsUpEnabled(false); handleIntent(getIntent()); }@Override protected void onNewIntent(Intent intent) { setIntent(intent); handleIntent(intent); }private void handleIntent(Intent intent) { if(Intent.ACTION_SEARCH.equals(intent.getAction())) query = intent.getStringExtra(SearchManager.QUERY); } }

company fragment.Java

public class companyFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.company, container, false); String temp = new SearchResultsActivity().query; TextView tv = (TextView) rootView.findViewById(R.id.textView1); tv.setText(temp); return rootView; }}

答案我回过头来实现了一个基本的搜索示例。希望这会让你朝着正确的方向前进。
