问题描述
我有一个ArrayAdapter的getView设置与数据列表视图中的项目。当我在ListView单击某一行，我想开始另一个活动，（我可以做），但一些数据的发送活动present的另一种观点。
我如何可以从getView访问的数据存储在onItemClick方法？
@覆盖
公共查看getView（INT位置，查看convertView，父母的ViewGroup）{
LayoutInflater吹气=（LayoutInflater）上下文
.getSystemService（Context.LAYOUT_INFLATER_SERVICE）; 查看rowView = inflater.inflate（R.layout.rotarowlayout，父母，
假）; TextView的STARTTIME =（TextView中）rowView
.findViewById（R.id.rowstarttime）;
TextView的持续时间=（TextView中）rowView

串[] itemsInRecord = record.split（，）;
Log.e（TAGitemin纪录=+ itemsInRecord.length）;
的String [] = recordItem新的String [itemsInRecord.length] 为（中间体X = 0; X＆下; itemsInRecord.length; X ++）{ recordItem [X] = itemsInRecord [X]; } //设置日期列表视图上方 textViewDate.setText（罗塔为+ recordItem [0] .substring（1，11））;
串withoutBraket = recordItem [0] .substring（11）;
串withoutSecs = withoutBraket.substring（0，6）; Log.e（TAGrecordItem =+ recordItem [2]）; 串_statusString = recordItem [2]的ToString（）修剪（）; 如果（_statusString.equalsIgnoreCase（已完成））{ statusField =C; }否则如果（_statusString.equalsIgnoreCase（NCR））{ statusField =NCR; }否则如果（_statusString.equalsIgnoreCase（等待））{ statusField =W;
} Log.e（TAGstatusField =+ statusField）; startTime.setText（withoutSecs +）;
duration.setText（recordItem [1] +分钟）;
status.setText（statusField）;
name.setText（+ recordItem [3] + recordItem [4]）;
CALLID = recordItem [5];
// needName = recordItem [6];
actualTimeIn.setText（这个称呼是在完成了+ recordItem [6] + - ）; 如果（！recordItem [7]的ToString（）。修剪（）。equalsIgnoreCase（]））{
串stripBracket = recordItem [7]的ToString（）修剪（）;
Log.e（TAGstripBracket =+ stripBracket）;
字符串stripBracket2 = stripBracket.substring（0,5）;
Log.e（TAG，SB后分裂=+ stripBracket2）;
actualTimeOut.setText（stripBracket2）;
} 返回rowView; }

公共无效onItemClick（适配器视图＆LT;＆GT;母公司，观景，INT位置，
长ID）{ Log.e（TAG，里面onItemClick）;
意图I =新意图（GetRota.this，someOtherActivity.class）;
i.putsomedata;
startActivity（ⅰ）; }
解决方案
使用 setTag（）和 getTag（）方法，你可以在 onItemClick从适配器的数据（）。像这样
在适配器类
@覆盖
公共查看getView（INT位置，查看convertView，父母的ViewGroup）{ rowView.setTag（yourdata_object）;
返回rowView;
}
在项目上点击
@覆盖
公共无效onItemClick（适配器视图＆LT;＆GT;母公司，观景，INT位置，长的id）{ YourDataObject项目=（YourDataObject）view.getTag（）;
意图I =新意图（GetRota.this，someOtherActivity.class）;
i.putsomedata;
startActivity（ⅰ）;
}
I have an ArrayAdapter whose getView sets the items in the listview with data. When i click a row in the listview i'd like to start another activity, (which i can do), but send that activity some of the data to present in another view.
How can i make the data from getView accessible in the onItemClick method?
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.rotarowlayout, parent,
false);
TextView startTime = (TextView) rowView
.findViewById(R.id.rowstarttime);
TextView duration = (TextView) rowView
.findViewById(R.id.rowduration);
TextView status = (TextView) rowView.findViewById(R.id.rowstatus);
TextView name = (TextView) rowView.findViewById(R.id.rowclientname);
TextView actualTimeIn = (TextView) rowView.findViewById(R.id.rowactualtimein);
TextView actualTimeOut = (TextView) rowView.findViewById(R.id.rowactualtimeout);
String record = list.get(position).toString();
String[] itemsInRecord = record.split(",");
Log.e(TAG, "itemin record = " + itemsInRecord.length);
String[] recordItem = new String[itemsInRecord.length];
for (int x = 0; x < itemsInRecord.length; x++) {
recordItem[x] = itemsInRecord[x];
}
//set date above listview
textViewDate.setText("Rota For " + recordItem[0].substring(1, 11));
String withoutBraket = recordItem[0].substring(11);
String withoutSecs = withoutBraket.substring(0, 6);
Log.e(TAG, "recordItem = " + recordItem[2]);
String _statusString = recordItem[2].toString().trim();
if(_statusString.equalsIgnoreCase("Completed")){
statusField = "c";
}else if(_statusString.equalsIgnoreCase("NCR")){
statusField = "NCR";
}else if(_statusString.equalsIgnoreCase("Waiting")){
statusField = "W";
}
Log.e(TAG, "statusField = " + statusField);
startTime.setText(withoutSecs+" " );
duration.setText( recordItem[1]+" mins ");
status.setText( statusField);
name.setText( " " + recordItem[3] + recordItem[4]);
callID = recordItem[5];
// needName = recordItem[6];
actualTimeIn.setText("This call was completed at " + recordItem[6] + " - ");
if( ! recordItem[7].toString().trim().equalsIgnoreCase( "]")){
String stripBracket = recordItem[7].toString().trim();
Log.e(TAG, "stripBracket = " + stripBracket);
String stripBracket2 = stripBracket.substring(0,5);
Log.e(TAG, "SB after split = " + stripBracket2 );
actualTimeOut.setText(stripBracket2);
}
return rowView;
}
.
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
Log.e(TAG, "inside onItemClick");
Intent i = new Intent(GetRota.this, someOtherActivity.class);
i.putsomedata;
startActivity(i);
}
解决方案
By Using setTag() and getTag() methods you can get data from the adapter in onItemClick(). like this
in adapter class
@Override
public View getView(int position, View convertView, ViewGroup parent) {
rowView.setTag(yourdata_object);
return rowView;
}
in on item click
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
YourDataObject item = (YourDataObject ) view.getTag();
Intent i = new Intent(GetRota.this, someOtherActivity.class);
i.putsomedata;
startActivity(i);
}
