我有一個列表視圖，我想顯示自定義數據，如生肖標誌圖像。星座標題。十二生肖內容和幾個按鈕。問題是沒有顯示數據我調試每一行和項目正確地添加到arraylist，然後到適配器但列表視圖顯示屏幕上爲空。自定義列表視圖人口項沒有得到顯示

getCount將（）要返回爲0 –

您在滾動型使用一個ListView，隨着列表的增長，您將無法看到整個ListView，因爲這些視圖會互相爭鬥...... – Sam

在你ZodicAdapter類 getCount將（）要返回爲0

使作爲

@Override 
public int getCount() { 
    // TODO Auto-generated method stub 
    return items.size(); 
}

0

您正在返回0getCount()，因此列表認爲該適配器中沒有項目。
