Android中listview 大小因分辨率而異

Android中listview 大小因分辨率而異代碼：

1. // 獲得手機分辨率
2. DisplayMetrics dm = new DisplayMetrics();
3. getWindowManager().getDefaultDisplay().getMetrics(dm);
4. String s = dm.widthPixels + "*" + dm.heightPixels;
6. // listview 因分辨率而異
7. if (s.equals("480*800") || s.equals("480*854"))
8. FixStyle.setListViewHeightBasedOnChildren(listViewActivity, 32);
9. else if (s.equals("320*480")) {
10. FixStyle.setListViewHeightBasedOnChildren(listViewActivity, 22);
12. }
13. else if (s.equals("540*960") || s.equals("720*1280")) {
14. Log.e("540*960", "540*960");
15. FixStyle.setListViewHeightBasedOnChildren(listViewActivity, 32);
17. }
20. import android.view.ViewGroup;
21. import android.widget.ListAdapter;
22. import android.widget.ListView;
24. public class FixStyle {
25. public static void setListViewHeightBasedOnChildren(ListView listView,int itemHeight) {
26. ListAdapter listAdapter = listView.getAdapter();
27. if (listAdapter == null) {
28. return;
29. }
31. int totalHeight = listAdapter.getCount() *itemHeight;
33. ViewGroup.LayoutParams params = listView.getLayoutParams();
34. params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
35. listView.setLayoutParams(params);
36. }
37. }
