Android設置BaseAdapter類中的佈局權重

我創建的應用程序只是在ListView中顯示一些數據，應使用適配器將此數據添加到Listview中。在這個適配器中，我試圖設置一個項目在列表中被點擊時的權重。我通過將權重設置爲1來獲得項目，但是當我嘗試將權重設置爲0時，沒有任何反應。Android設置BaseAdapter類中的佈局權重

在這部分代碼中，將佈局權重設置爲1的第一部分確實有效，但將其設置回0不起作用。

stat_item_container.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      Log.w("HiscoreAdapter","Stat item height "+gained_tracker_container.getHeight()); 
      if(gained_tracker_container.getHeight() == 0){ 
       gained_tracker_container.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT,1)); 
      }else{ 
       Log.w("HiscoreAdapter","Setting stat item weight to 0"); 
       gained_tracker_container.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT,0)); 
      } 
     } 
    });

適配器類

public class HiscoreAdapter extends BaseAdapter { 
 

 
    private Context context; 
 
    private ArrayList<HiscoreItem> items; 
 

 
    public HiscoreAdapter(Context context, ArrayList<HiscoreItem> items){ 
 
     this.context = context; 
 
     this.items = items;

你的意思是你想刷新列表視圖？ –

@AminMemariani你認爲這樣可以解決嗎？ –

是的，我認爲是的！ –

ArrayListObject.clear(); 
    ArrayListObject.addAll(DBClass.listAll(DBClass.class)); 
    AdapterObject.notifyDataSetChanged(); 
    listViewObject.invalidateViews(); 
    listViewObject.refreshDrawableState();

試試這個代碼刷新的ListView。將它添加到onItemClickedListener中的return語句之前。

在第二行中，我用SugarORM調用了我的數據

你可以看到這個代碼作爲一個例子：https://github.com/AminMemariani/ bMICalculator /斑點/主/應用程序/ SRC /主/ JAVA/COM/aminmemariani /應用/ bmicalculator/History.java –
