如果我在正常的Activity中有一個GridView,它工作正常。但在這裏,我在PopupWindow,我嘗試了所有的工作,但onItemClick不會被調用!我試着用下面的,這是對大多數人的解決方案,但他們沒有爲我工作(也許我已經被濫用呢?):PopupWindow中的GridView的setOnItemClickListener不起作用
android:clickable="false"
android:focusable="false"
android:focusableInTouchMode="false"
android:descendantFocusability="blocksDescendants"
活動的部分:
bgGrid.setAdapter(new ImageAdapter(context));
bgGrid.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View v, int position, long id) {
Log.v("CLICK", "ITEM SELECTED " + position);
}
});
pw = new PopupWindow(layout, posx, posy);
pw.setOutsideTouchable(false);
pw.showAtLocation(layout, Gravity.CENTER, 0, 0); //bgGrid is part of layout
和xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:padding="5dip" >
<GridView

</LinearLayout>
ImageAdapter
public class ImageAdapter extends BaseAdapter {
private Context mContext;
public ImageAdapter(Context c) {
mContext = c;
}
public int getCount() {
return mThumbIds.length;
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView;
if (convertView == null) { mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(160, 120));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
} else {
imageView = (ImageView) convertView;
}
imageView.setImageResource(mThumbIds[position]);
return imageView;
}
整個彈出部分位於PereferenceActivity中,我有一個偵聽器,它檢測Preference上的單擊並打開Popup。顯然,只能有一個偵聽器,並且我無法將onClick設置爲首選項,所以我不知道如何解決此問題(onPreferenceClick從未檢測到任何點擊)。這就要求彈出(我能得到該次點擊的唯一途徑)第一個監聽:
images = (Preference) findPreference("prefs_bg");
images.setOnPreferenceClickListener(new BackgroundColorSelector());
點擊在屏幕上顯示(我甚至嘗試drawSelectorOnTop),但不管如何,單擊不會得到通過。
事件是否進入彈出窗口本身? – Nathaniel 2013-02-08 16:55:42
項目選擇是否打印到logcat? – NPike 2013-02-08 17:17:39
@NPike不,它不 – 2013-02-08 17:20:06
