如何将ARGB(255 0 255 0)
颜色转换为HEXADECIMAL
颜色。我在数据库中有 ARGB 颜色,我使用 JSON 格式的 Web 服务进行检索。
我想在文本字段中添加颜色TAG_DIFF_P (R.id.l7)
这是我的代码,如何在文本字段的背景中添加颜色
try {
JSONObject json1 = jParser.getJSONFromUrl(myUrl);
// Getting Array of Contacts
JSONArray list = json1.getJSONArray(TAG_JSONDataResult);
// looping through All Contacts
for(int i = 0; i < list.length(); i++){
JSONObject c = list.getJSONObject(i);
String GRPNAME = c.getString(TAG_GRPNAME);
String QTY = c.getString(TAG_QNT);
String BUDGET = c.getString(TAG_BUDGET);
String STOCK = c.getString(TAG_STOCK);
String DIFF = c.getString(TAG_DIFF);
String DIFF_P = c.getString(TAG_DIFF_P);
String COLOR = c.getString(TAG_COLOR);
// creating new HashMap
HashMap<String, String> map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(TAG_GRPNAME, GRPNAME);
map.put(TAG_QNT, QTY);
map.put(TAG_BUDGET, BUDGET);
map.put(TAG_STOCK, STOCK);
map.put(TAG_DIFF, DIFF);
map.put(TAG_DIFF_P, DIFF_P);
// adding HashList to ArrayList
contactList.add(map);
}
} catch (JSONException e) {
e.printStackTrace();
}
/**
* Updating parsed JSON data into ListView
* */
ListAdapter adapter = new SimpleAdapter(this, contactList,
R.layout.list_item,
new String[] { TAG_GRPNAME, TAG_QNT, TAG_BUDGET, TAG_STOCK, TAG_DIFF, TAG_DIFF_P, },
new int[] {
R.id.l2, R.id.l3, R.id.l4, R.id.l5, R.id.l6, R.id.l7});
lv2.setAdapter(adapter);
}
