Android中listview 大小因分辨率而异

 

 

// 获得手机分辨率
	DisplayMetrics dm = new DisplayMetrics();
	getWindowManager().getDefaultDisplay().getMetrics(dm);
	String s = dm.widthPixels + "*" + dm.heightPixels;

	// listview 因分辨率而异
	if (s.equals("480*800") || s.equals("480*854"))
		FixStyle.setListViewHeightBasedOnChildren(listViewActivity, 32);
	else if (s.equals("320*480")) {
		FixStyle.setListViewHeightBasedOnChildren(listViewActivity, 22);

	}
	else if (s.equals("540*960") || s.equals("720*1280")) {
		Log.e("540*960", "540*960");
		FixStyle.setListViewHeightBasedOnChildren(listViewActivity, 32);

	}
