我創建了一個自定義列表視圖,每個元素具有一個webview。我的自定義列表視圖元素的位置順序的問題
我的問題是,當我點擊一個元素,它需要壞元素positon。
這裏是我的自定義列表視圖
public class ListViewCustomAdapter extends BaseAdapter {
public ArrayList<String> mywebview;
public Activity context;
public LayoutInflater inflater;
public ListViewCustomAdapter(Activity context, ArrayList<String> mywebview) {
//super();
this.mywebview = new ArrayList<String>();
this.context = context;
this.mywebview = mywebview;
this.inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
return mywebview.size();
}
@Override
public String getItem(int position) {
return mywebview.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
public static class ViewHolder {
WebView mywebviewholder;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.mylistview2, null, false);
holder.mywebviewholder = (WebView) convertView
.findViewById(R.id.weblistview);
holder.mywebviewholder
.setOnTouchListener(new my.student.application.WebViewClickListener(
holder.mywebviewholder, parent, position));
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.mywebviewholder.loadDataWithBaseURL("", mywebview.get(position)
.toString(), "text/html", "UTF-8", "");
return convertView;
}
我的WebView點擊收聽
public class WebViewClickListener implements View.OnTouchListener {
private int position;
private ViewGroup vg;
private WebView wv;
public WebViewClickListener(WebView wv, ViewGroup vg, int position) {
this.vg = vg;
this.position = position;
this.wv = wv;
}
public boolean onTouch(View v, MotionEvent event) {
int action = event.getAction();
switch (action) {
case MotionEvent.ACTION_CANCEL:
return true;
case MotionEvent.ACTION_UP:
sendClick();
return true;
}
return false;
}
public void sendClick() {
ListView lv = (ListView) vg;
lv.performItemClick(wv, position, 0);
}
感謝您的幫助
編輯:奇怪的事情我發現。如果我listview.xml我改變我的WebView,當我點擊一個元素的高度尺寸,它改變了元素
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:orientation="vertical" android:padding="3dip">
<WebView android:id="@+id/weblistview" android:layout_width="fill_parent"
android:layout_height="200dip"></WebView>
的位置有了這個喚起注意順序,如果我有5種元素是:2 1 0 2 1
我實在看不出哪裏出了問題
啊,最後它的工作。非常感謝您的回答,現在看起來更簡單和邏輯。 – joris
