Android：為什么聊天列表視圖適配器無法正常工作？
[英]Android: Why chat list view adapter doesn't work properly?
問題描述
當我調用適配器並嘗試添加消息時，我正在編寫一個 android 聊天應用程序，它會關閉並且聊天活動被粉碎，然后我回到上一個活動。 這些是我的課程： OneMessage.java：
package com.mycompany.myapp;
public class OneMessage
{
public boolean left;
public String text;
public OneMessage(boolean left,String text) {
super();
this.left=left;
this.text=text;
}
}
& kada.java = 一個名為k 適配器的適配器：
package com.mycompany.myapp;
//imports here
public class kada extends ArrayAdapter<OneMessage>
{
private TextView tv;
private List<OneMessage> list=new ArrayList<OneMessage>();
private LinearLayout space;
public void add(OneMessage object) {
list.add(object);
super.add(object);
}
public kada(Context context,int textViewResourceId) {
super(context,textViewResourceId);
}
public int getCount() {
return this.list.size();
}
@Override
public OneMessage getItem(int position)
{
return this.list.get(position);
}
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
View row=convertView;
if (row==null) {
LayoutInflater li=(LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
li.inflate(R.layout.me,parent,false);
}
space=(LinearLayout) row.findViewById(R.id.space);
OneMessage om=getItem(position);
tv=(TextView) row.findViewById(R.id.textview);
tv.setText(om.text);
space.setGravity(om.left ? Gravity.LEFT : Gravity.RIGHT);
return row;
}
public Bitmap decodeToBitmap(byte[] db) {
return BitmapFactory.decodeByteArray(db,0,db.length);
}
}
這是我的日志：

我自己發現了問題：
在適配器 java 文件kada.java 中，當我需要將氣泡布局膨脹到 ListView 中時，我沒有定義行視圖。 膨脹代碼必須是：
LayoutInflater li=(LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row=li.inflate(R.layout.me,parent,false);
而不是：
LayoutInflater li=(LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
li.inflate(R.layout.me,parent,false);
帶過濾器的自定義列表適配器在android中不起作用
