首先我會建議分裂UI和數據訪問的代碼，然後在不同的威脅加載數據，而不是在UI線程

嘗試用虛擬數據先加載屏幕檢查佈局和屏幕工作正常，然後將其與保存的數據

我是初學者，此代碼適用於連接到「DAL」活動不是片段的我想要的列表視圖在片段 – Amr93

thx的問題，但它很容易使listview充滿了離線數組數據,,,我想加載這個數據來自mysql數據庫 – Amr93

您正在膨脹的newslayout雖然您的佈局是**news_itm.xml**

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
myView inflater.inflate(R.layout.**newslayout**,container,false);
