希望有人能幫助我。我有一個包含listview的佈局,列表視圖中的每個項目都包含表示星期幾的單獨文本字段 - > SMTWTFS 我想要做的是更改文本項的顏色,如果它們在數據庫。這幾乎可以工作,但我注意到當列表視圖中的第一行在其他列表行中設置時,所有項目的顏色都會改變。來自光標的Android ViewBinder值
我的文字資料的聲明如下
textSUN = (TextView) v.findViewById(R.id.textSUN);
textMON = (TextView) v.findViewById(R.id.textMON);
textTUE = (TextView) v.findViewById(R.id.textTUE);
textWED = (TextView) v.findViewById(R.id.textWED);
textTHU = (TextView) v.findViewById(R.id.textTHU);
textFRI = (TextView) v.findViewById(R.id.textFRI);
textSAT = (TextView) v.findViewById(R.id.textSAT);
然後我查詢我的數據庫,並設置適配器
db = new DatabaseHandler(getActivity());
mCursor=db.getReadableDatabase().rawQuery("SELECT rowid _id,* "+
"FROM table", null);
adapter = new SimpleCursorAdapter(getActivity(),
R.layout.list_row, mCursor,
new String[] {DatabaseHandler.KEY_SUNDAY, DatabaseHandler.KEY_MONDAY,DatabaseHandler.KEY_TUESDAY,DatabaseHandler.KEY_WEDNESDAY, DatabaseHandler.KEY_THURSDAY, DatabaseHandler.KEY_FRIDAY,
DatabaseHandler.KEY_SATURDAY,},
new int[] {R.id.textSUN,R.id.textMON, R.id.textTUE, R.id.textWED, R.id.textTHU, R.id.textFRI, R.id.textSAT});
最後,我嘗試設置在視圖中粘結劑的顏色,如果返回的值是1從分區
adapter.setViewBinder(new SimpleCursorAdapter.ViewBinder() {
@Override
public boolean setViewValue(View view, Cursor cursor, int
columnIndex) {
final int sun_column = cursor.getColumnIndex("sun");
final int mon_column = cursor.getColumnIndex("mon");
final int tue_column = cursor.getColumnIndex("tue");
final int wed_column = cursor.getColumnIndex("wed");
final int thu_column = cursor.getColumnIndex("thu");
final int fri_column = cursor.getColumnIndex("fri");
final int sat_column = cursor.getColumnIndex("sat");
}
if (columnIndex == sun_column) {
int sun = cursor.getInt(cursor.getColumnIndexOrThrow("sun"));
if(sun == 1){
((TextView) view).setTextColor(Color.parseColor("#FFFFFF"));
}
return true;
}
if (columnIndex == mon_column) {
int mon = cursor.getInt(cursor.getColumnIndexOrThrow("mon"));
if(mon == 1){
((TextView) view).setTextColor(Color.parseColor("#FFFFFF"));
}
return true;
}
if (columnIndex == tue_column) {
int tue = cursor.getInt(cursor.getColumnIndexOrThrow("tue"));
if(tue == 1){
((TextView) view).setTextColor(Color.parseColor("#FFFFFF"));
}
return true;
}
if (columnIndex == wed_column) {
int wed = cursor.getInt(cursor.getColumnIndexOrThrow("wed"));
if(wed == 1){
((TextView) view).setTextColor(Color.parseColor("#FFFFFF"));
}
return true;
}
if (columnIndex == thu_column) {
int thu = cursor.getInt(cursor.getColumnIndexOrThrow("thu"));
if(thu == 1){
((TextView) view).setTextColor(Color.parseColor("#FFFFFF"));
}
return true;
}
if (columnIndex == fri_column) {
int fri = cursor.getInt(cursor.getColumnIndexOrThrow("fri"));
if(fri == 1){
((TextView) view).setTextColor(Color.parseColor("#FFFFFF"));
}
return true;
}
if (columnIndex == sat_column) {
int sat = cursor.getInt(cursor.getColumnIndexOrThrow("sat"));
if(sat == 1){
((TextView) view).setTextColor(Color.parseColor("#FFFFFF"));
}
return true;
}
return false;
}
});
lv = (ListView) v.findViewById(R.id.listView);
lv.setAdapter(adapter);
也許我正在談論這一切都是錯誤的?它幾乎可以工作。
非常感謝
