動態添加父佈局並動態添加子佈局

Question

我目前已經設置了我的代碼，用於在行佈局中顯示父佈局中的一個TextView和同一個佈局中的3個textview。我的問題是，當我想將其設置在同一行中時，3個textview顯示爲3個不同的行。我想我需要一個孩子linerlayout但這並沒有爲我工作。這3個文本視圖是動態的，因爲輸入的數據是動態的，所以我無法設置一定數量的文本視圖。這裏是我的我的代碼將如何顯示的代碼示例....

Screenshot of 3 textviews in different rows

我的代碼如下：

//initialize linearlayout 
public LinearLayout pickcontainerLayout; 


int counter = 0; 
//creating a new view by using functions, using keys and values from multimap 
     for (String key : myMultimap.keySet()) { 
      ArrayList<SaleOrder> sale = new ArrayList<>(); 
      for (SaleOrder s : myMultimap.get(key)) { 
       sale.add(s); 
      } 
      pickcontainerLayout.addView(containerLayoutfunction(counter, sale.size(), sale, key)); 
      View line = new View(getContext()); 
      line.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,1)); 
      line.setBackgroundColor(Color.rgb(255,255,255)); 
      pickcontainerLayout.addView(line); 
      counter++; 
     } 
private TextView newSku(int id, String sku) { 
    TextView skuView = new TextView(getContext()); 
    skuView.setId(id); 
    skuView.setText("SKU: " + sku); 
    /*LinearLayout.LayoutParams skuParams = new LinearLayout.LayoutParams(
      ViewGroup.LayoutParams.WRAP_CONTENT, 
      ViewGroup.LayoutParams.WRAP_CONTENT 
    ); 
    skuView.setLayoutParams(skuParams);*/ 
    skuView.setGravity(Gravity.LEFT); 
    return skuView; 
} 
private TextView newqty(int id, String qty) { 
    TextView qtyView = new TextView(getContext()); 
    qtyView.setId(id); 
    qtyView.setText("QTY: " + qty); 
    /*LinearLayout.LayoutParams qtyParams = new LinearLayout.LayoutParams(
      ViewGroup.LayoutParams.WRAP_CONTENT, 
      ViewGroup.LayoutParams.WRAP_CONTENT 
    ); 
    qtyView.setLayoutParams(qtyParams);*/ 
    qtyView.setGravity(Gravity.CENTER); 
    return qtyView; 
} 
private TextView newlocation(int id, String location) { 
    TextView loc = new TextView(getContext()); 
    loc.setId(id); 
    loc.setText("Location: " + location); 
    /*LinearLayout.LayoutParams locParams = new LinearLayout.LayoutParams(
      ViewGroup.LayoutParams.WRAP_CONTENT, 
      ViewGroup.LayoutParams.WRAP_CONTENT 
    ); 
    loc.setLayoutParams(locParams);*/ 
    loc.setGravity(Gravity.RIGHT); 
    return loc; 
} 
private LinearLayout containerLayoutfunction(int parentid, int rowId, ArrayList<SaleOrder> s, String key) { 
    LinearLayout layout = new LinearLayout(getContext()); 

    layout.addView(newSale(parentid, key)); 
    layout.setOrientation(LinearLayout.VERTICAL); 
    for (int i = 0; i<rowId;i++) { 
     //LinearLayout layoutchild = new LinearLayout(getContext()); 
     //layoutchild.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)); 
     //layoutchild.setOrientation(LinearLayout.HORIZONTAL); 
     layout.addView(newSku(rowId,s.get(i).getSku())); 
     layout.addView(newqty(rowId,s.get(i).getQty())); 
     layout.addView(newlocation(rowId,s.get(i).getlocation())); 
    } 
    return layout; 
}

你應該換三個TextViews在的LinearLayout與水平方向，所以textviews將自動在同一行。容器將FILL_PARENT水平設置爲LayuoutParam，而textview應該具有WRAP_CONTENT，重力分配給左（第一個），CENTER（第二）和右（第三）。
