以編程方式創建佈局

Question

我嘗試從代碼創建佈局時出現問題。問題是我正在創建水平和垂直的不同佈局，並且具有權重。我們的想法是創建一個類似於圖像1的顯示器，但現在正在顯示圖像2.

Image 1

Image 2

¿任何人都可以幫我嗎？如果你需要更多的解釋，我會嘗試回答你的問題。

Thx 4 all。

更具體的問題是，當clase.getListaTareas（）的元素多於一個時。然後顯示器顯示的唯一孩子是最後添加的。我認爲這個問題是在這部分代碼，但我不知道......

for(NotificacionTareas tareaIndv: clase.getListTareas()){ 
        LinearLayout linNuevaTarea=new LinearLayout(this); 
        LinearLayout.LayoutParams linLayParamsNuevaTarea=new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT); 
        linLayParamsNuevaTarea.setMargins(45, 0, 0, 0); 
        linNuevaTarea.setLayoutParams(linLayParamsNuevaTarea); 
        linNuevaTarea.setWeightSum(3); 
        linNuevaTarea.setOrientation(LinearLayout.HORIZONTAL); 


        LinearLayout linGroupTarea=new LinearLayout(this); 
        linGroupTarea.setLayoutParams(new LinearLayout.LayoutParams(0, LinearLayout.LayoutParams.WRAP_CONTENT,2.3f)); 
        linGroupTarea.setWeightSum(2); 
        linGroupTarea.setOrientation(LinearLayout.VERTICAL); 


        TextView txtAsign= new TextView(this); 
        txtAsign.setText(tareaIndv.getAsignatura()); 
        txtAsign.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 0,1f)); 

        linGroupTarea.addView(txtAsign); 
        TextView txtDescrip= new TextView(this); 
        txtDescrip.setText(tareaIndv.getDescripcion().length()>20?tareaIndv.getDescripcion().substring(0,20)+"...":tareaIndv.getDescripcion()); 

        LinearLayout.LayoutParams linLayParamsDescripcion=new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,0,1); 
        linLayParamsDescripcion.setMargins(15, 0, 0, 0); 
        txtDescrip.setLayoutParams(linLayParamsDescripcion); 

        linGroupTarea.addView(txtDescrip); 

        TextView txtTiempo= new TextView(this); 
        txtTiempo.setText(tareaIndv.getTiempo() + " min."); 
        txtTiempo.setLayoutParams(new LinearLayout.LayoutParams(0, LinearLayout.LayoutParams.MATCH_PARENT,0.7f)); 

        linNuevaTarea.addView(linGroupTarea); 
        linNuevaTarea.addView(txtTiempo); 
        linLayGroupTareas.addView(linNuevaTarea); 



       } 
       listTarea.add(linNuevoClaseCabecera); 
       linNuevoClaseCabecera.addView(linLayGroupTareas); 

       linNuevo.addView(linNuevoClaseCabecera); 

Answer 1

我猜linLayGroupTareas應該垂直。

循環之前加入這一行：

linLayGroupTareas.setOrientation(LinearLayout.VERTICAL);
