Android CustomListAdapter從EditText設置TextView TAB中的OnClick

Question

在我的其中一個選項卡上，我有一個Listview，當用戶在edittext上輸入文本然後按下按鈕時，我想填充該列表。 edittext和按鈕與列表視圖一起在選項卡式佈局上。

textview和imageview在customlistadapter中設置。但是當我按下按鈕什麼都沒有發生，我似乎無法解決原因。

Tab3.java

@Override 
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
     final View v = inflater.inflate(R.layout.tab3, container, false); 

     final EditText notes = (EditText) v.findViewById(R.id.editText); 
     listView=(ListView)v.findViewById(R.id.list); 
     Button button = (Button) v.findViewById(R.id.button3); 
     String note = notes.getText().toString(); 

     int[] cross = new int[]{R.drawable.cross}; 
     String [] notesofrules = new String[]{note}; 

     final CustomListAdapter adapter=new CustomListAdapter(this.getActivity(), notesofrules, cross); 

     listView=(ListView) v.findViewById(R.id.list); 

     Button rulesSet = (Button)v.findViewById(R.id.button3); 
     rulesSet.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) 
      { 
       listView.setAdapter(adapter); 
      } 
     }); 
     return v; 
     } 

CustomListAdaper：

public CustomListAdapter(Activity context, String[] notes, int[] imageCross) { 
     super(context, R.layout.item); 
     // TODO Auto-generated constructor stub 
     this.context=context; 
     this.notes = notes; 
     this.imageCross = imageCross; 
    } 

    public View getView(final int position, View view, ViewGroup parent) { 
     LayoutInflater inflater=context.getLayoutInflater(); 
     View rowView=inflater.inflate(R.layout.item, null,false); 

     TextView ruleNotesSet = (TextView) rowView.findViewById(R.id.textView1); 
     ImageView image = (ImageView) rowView.findViewById(R.id.icon); 

     image.setImageResource(imageCross[position]); 
     ruleNotesSet.setText(notes[position]); 
     return rowView; 
    }

我覺得你的適配器是空的。您只需要設置一次，然後在您的適配器中進行刷新功能，您將在您的活動onClick中調用

public void refresh(String[] notes, int[] imageCross) { 
    this.notes = notes; 
    this.imageCross = imageCross; 
    this.notifySataSetChanged(); 
}
