我有一個報價應用程序有一個「加載更多」按鈕，只有當報價列表大小爲15時纔可見。現在我想更改條件，以便只有在報價列表大小超過15我當前的代碼是像下面，我試圖將其更改爲：小於或等於條件Android
if(c.getCount()<=15){
// Not Showing Load More Button
}
，但它沒有顯示我的按鈕。
我該按鈕的代碼如下：
final Button btnLoadMore=new Button(this);
btnLoadMore.setBackgroundColor(Color.parseColor("#351802"));
btnLoadMore.setTextColor(Color.parseColor("#e8d8a7"));
btnLoadMore.setTypeface(btnLoadMore.getTypeface(), Typeface.BOLD);
btnLoadMore.setText("Load More Quotes");
if(c.getCount()<15){
// Not Showing Load More Button
}
else {
list.addFooterView(btnLoadMore);}
list.setAdapter(adapter);
anifadein=AnimationUtils.loadAnimation(getApplicationContext(), R.anim.slidedown);
list.startAnimation(anifadein);
// Click event for single list row
list.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
map = quotesList.get(position);
Intent intent = new Intent(QuotesActivity.this,
QuoteDialogActivity.class);
int itemPosition = position;
if(startingPoint>=30){
intent.putExtra("Pos", itemPosition+1);
intent.putExtra("LstCount", list.getCount()-1);
}else{
intent.putExtra("Pos", itemPosition+1);
intent.putExtra("LstCount", list.getCount());}
intent.putExtra("QuoteId", map.get(KEY_ID));
intent.putExtra("quotesType", quType);
intent.putExtra("startFrom", getIntent().getStringExtra("startFrom"));
intent.putExtra("Quotes", quotesList);
// Log.i("COUNT",""+(itemPosition+1)+"-"+list.getCount());
intent.putExtra("Fav", map.get(KEY_FAVORITE));
startActivity(intent);
if (mInterstitial.isLoaded()) {
mInterstitial.show();
}
}
});
btnLoadMore.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
if(btnLoadMore.getVisibility()==View.VISIBLE){
Cursor newC = null;
if (quType != 0) {
switch (quType) {
case 1:
newC = db.getQuotes(""+startingPoint);
break;
case 2:
newC = db.getFavoriteQuotes(""+startingPoint);
//page.setVisibility(View.GONE);
break;
case 3:
newC = db.getAuthorQuotes(getIntent().getStringExtra("AuthorId"),""+startingPoint);
// page.setVisibility(View.GONE);
break;
}
}
// Starting a new async task
if(newC.getCount()<15){
btnLoadMore.setVisibility(View.INVISIBLE);
}
startingPoint+=15;
do{
map = new HashMap<String, String>();
// adding each child node to HashMap key => value
map.put(KEY_ID, newC.getString(newC.getColumnIndex(KEY_ID)));
map.put(KEY_TEXT, newC.getString(newC.getColumnIndex(KEY_TEXT)));
map.put(KEY_AUTHOR, newC.getString(newC.getColumnIndex(KEY_AUTHOR)));
map.put(KEY_PICTURE, newC.getString(newC.getColumnIndex(KEY_PICTURE)));
map.put(KEY_PICTURE_SDCARD, String.valueOf(newC.getInt(newC
.getColumnIndex(KEY_PICTURE_SDCARD))));
map.put(KEY_WEB_ID,
String.valueOf(newC.getInt(newC.getColumnIndex(KEY_WEB_ID))));
//Log.i("web_id",String.valueOf(newC.getInt(newC.getColumnIndex(KEY_ID))));
map.put(KEY_FAVORITE, newC.getString(newC.getColumnIndex(KEY_FAVORITE)));
// adding HashList to ArrayList
quotesList.add(map);
if (mInterstitial.isLoaded()) {
mInterstitial.show();
}
} while (newC.moveToNext());
adapter.notifyDataSetChanged(); }}
});
}
}
