安卓：有問題fragmentManager（錯誤XML inflateExeption）

Question

我第一次運行onClickMap功能（點擊按鈕），它的工作原理，並出現mapFragment，然後我點擊spotList按鈕，它也能工作和SpotListFragment出現，然後我再次運行onClickMap和應用程序崩潰！

屏幕圖像：

MainActivity.class

package com.pap.myspots; 

import com.pap.myspots.adapter.TabsPagerAdapter; 
import com.pap.myspots.fragments.MapFragment;

import android.widget.TextView; 

public class MainActivity extends FragmentActivity implements 
     ActionBar.TabListener { 

    private ViewPager viewPager; 
    private TabsPagerAdapter mAdapter; 
    private ActionBar actionBar; 
    String local; 
    // Tab titles 

    @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 

      ImageView mapTab = new ImageView(this); 
      mapTab.setBackgroundColor(Color.parseColor("#ffbb33")); 
      //mapTab.setImageResource(R.drawable.notificationsicon); 
      actionBar.addTab(actionBar.newTab().setIcon(R.drawable.nicon) 
        .setTabListener(this)); 
      actionBar.addTab(actionBar.newTab().setIcon(R.drawable.micon) 
        .setTabListener(this)); 
      actionBar.addTab(actionBar.newTab().setIcon(R.drawable.sicon) 
        .setTabListener(this)); 

     /** 
     * on swiping the viewpager make respective tab selected 
     * */ 
     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) { 
      } 
     }); 
    } 

    public void clickMap(View v){ 
     MapFragment mapfragment = new MapFragment(); 
     getSupportFragmentManager().beginTransaction() 
     .replace(R.id.frame, mapfragment).commit(); 
    } 

    public void clickList(View v){ 
     SpotListFragment listfragment = new SpotListFragment(); 
     getSupportFragmentManager().beginTransaction() 
     .replace(R.id.frame, listfragment).commit(); 
    } 



    @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) { 
    } 

} 

fragment_home.xml：

添加到這一點您mapFragment。

@Override 
    public void onDestroyView() { 
     super.onDestroyView(); 
     try { 
      SupportMapFragment fragment = (SupportMapFragment) getActivity() 
        .getSupportFragmentManager().findFragmentById(R.id.map); 
      if (fragment != null) 
       getFragmentManager().beginTransaction().remove(fragment) 
         .commit(); 

     } catch (IllegalStateException e) { 
     } 
    } 

您需要正確銷燬Map碎片！
