我希望你的幫助如下,我如何創建一個自定義可擴展列表,並把他們每個人保存在SD卡中的圖像,我有一個數據庫與每個圖像的路徑。創建可擴展列表與保存在SD卡中的圖像
cursor = builder.query(
/* from */ Usuario.getInstance().getReadableDatabase(),
/* select */ columnsToReturn,
/* where */ Usuario.CPF_KEY + " = \'" + LastLoginData.getCpf() + "\'",
null, null, null,
/* order by */ Usuario.REG_ID_KEY + " ASC");
listAdapter = new SimpleCursorTreeAdapter(
this, cursor, R.layout.registro_parent,
new String[] { Usuario.REG_DATE_KEY, Usuario.REG_TYPE_KEY, Usuario.REG_STATUS_KEY },
new int[] { R.id.textData, R.id.textRegTipo, R.id.textStatus },
R.layout.registro_child,
new String[] { Usuario.REG_MEDIA_THUMB_KEY, Usuario.REG_INFO_KEY },
new int[] {R.id.imgSnapshot2 , R.id.textComentarios })
{
@Override
protected Cursor getChildrenCursor(Cursor cursor) {
String id = cursor.getString(cursor.getColumnIndexOrThrow(Usuario.REG_ID_KEY));
SQLiteDatabase db = Usuario.getInstance().getWritableDatabase();
String query = "select " + Usuario.REG_ID_KEY + ", " + Usuario.REG_MEDIA_THUMB_KEY + ", " + Usuario.REG_INFO_KEY + " from " + Usuario.REG_TABLE + " where " + Usuario.REG_ID_KEY + "='" + id + "'";
Cursor cur = db.rawQuery(query, null);
return cur;
}
@Override
protected void bindGroupView(View view, Context context, Cursor cursor, boolean isExpanded) {
super.bindGroupView(view, context, cursor, isExpanded);
ImageView img = (ImageView)view.findViewById(R.id.imageExpand);
if(img != null) {
if(isExpanded) {
img.setImageResource(R.drawable.btn_circulo_baixo);
}
else {
img.setImageResource(R.drawable.btn_circulo_dir);
}
}
TextView status = (TextView)view.findViewById(R.id.textStatus);
if(status != null) {
String s = status.getText().toString();
if(s.equals(getString(R.string.Enviada))) {
status.setTextColor(0xffff0000);
}
else if(s.equals(getString(R.string.EmAndamento))) {
status.setTextColor(0xffffcc00);
}
else if(s.equals(getString(R.string.Atendida))) {
status.setTextColor(0xff00cc00);
}
else {
status.setTextColor(0xff808080);
}
}
if(isExpanded) {
img = (ImageView)view.findViewById(R.id.imageRodape);
if(img != null) {
img.setVisibility(View.INVISIBLE);
}
}
else {
img = (ImageView)view.findViewById(R.id.imageRodape);
if(img != null) {
img.setVisibility(View.VISIBLE);
}
}
}
};
listView.setAdapter(listAdapter);
此代碼插入的一切權利,但沒有圖片:(可以有人幫忙^^ 謝謝你們^^
如何使現在擴張將是一個幫助,如果它是另有一個例子
