我正在使用自定義ListView與自定義ArrayAdapter爲我的自定義對象。我使用來自xml文件的已分析數據填充我的ListView。我能夠用這些數據填充ListView，但我想切換到不同的活動取決於哪個項目被點擊。我可以與OnItemClick自定義ListView上的問題
INT位置
該項目被點擊展示，但我怎麼能找回例如點擊的按鈕的名字嗎？
我的代碼：
/**
* Setup
* */
@SuppressWarnings("unchecked")
private void setup() throws IOException {
device_array = new ArrayList<Device>();
//-----------------ACTIONBAR------------------------------------
//activates the default ActionBar
ActionBar actionBar = getActionBar();
actionBar.show();
// set the app icon as an action to go home
actionBar.setDisplayHomeAsUpEnabled(true);
//-------------------INTENT--------------------------------------
//get data from Intent
Intent intent = getIntent();
Name = intent.getStringExtra("Projectname");
IP = intent.getStringExtra("RouterIP");
URL = intent.getStringExtra("URL");
Port = intent.getStringExtra("Port");
//-------------------TEXTVIEWS+LISTVIEW---------------------------------------
nameproject = (TextView)findViewById(R.id.nameproject);
nameproject.setText("Projektname: "+Name);
routerip = (TextView)findViewById(R.id.routerip);
routerip.setText("KNX/IP-Router-Adresse: "+IP);
port = (TextView)findViewById(R.id.port);
port.setText(":"+Port);
url = (TextView)findViewById(R.id.url);
url.setText("URL: "+URL);
//Fill ListView
display_listview();
devices = (ListView)findViewById(R.id.deviceList);
adapter = new DeviceAdapter(this,
R.layout.listviewitem_device, device_array);
//add a view which is shown if the ListView is empty
devices.setEmptyView(findViewById(R.id.empty_list_view));
//Click on item in listview
devices.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent i = new Intent(ProjectView.this, OnOff.class);
i.putExtra("Uniqid","From_ProjectView_Activity");
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(i);
}
});
devices.setAdapter(adapter);
