我的 ListView 问题下的Android额外空白空间

Question

我的 android 应用程序需要一些帮助。我在 ScrollView 中有 2 个 ListView 。我希望我的 ListView 不可滚动以查看我所有的 ListView 项目。所以这是我列出所有项目的代码:

public class CustomList extends ListView
{

boolean expanded = false;

public CustomList(Context context)
{
    super(context);
}

public CustomList(Context context, AttributeSet attrs)
{
    super(context, attrs);
}

public CustomList(Context context, AttributeSet attrs,int defStyle)
{
    super(context, attrs, defStyle);
}

public boolean isExpanded()
{
    return expanded;
}

@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
    // HACK! TAKE THAT ANDROID!
    if (isExpanded())
    {
        // Calculate entire height by providing a very large height hint.
        // But do not use the highest 2 bits of this integer; those are
        // reserved for the MeasureSpec mode.
        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);

        ViewGroup.LayoutParams params = getLayoutParams();
        params.height = getMeasuredHeight();
    }
    else
    {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }
}

public void setExpanded(boolean expanded)
{
    this.expanded = expanded;
}
}

这是我的 .xml:

            android:id="@+id/textView2"
            android:layout_weight="1"
            android:textAlignment="textStart"
            android:textColor="@android:color/holo_red_dark" />
    </LinearLayout>

    <com.example.cagri.mobilyateknikservis.CustomList
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:listSelector="@android:color/white"
        android:background="@android:color/white"
        android:id="@+id/lstParcalar"
        android:fadingEdge="none"
        android:focusable="false"
        android:scrollbars="none" />

</LinearLayout>

</ScrollView>

还有我的自定义 ListView 适配器:

public class ParcaAdapter extends BaseAdapter {
private LayoutInflater inflater;
private List<Parcalar> parcaBilgileri;

public ParcaAdapter(Activity activity, List<Parcalar> parca)
{
    inflater = (LayoutInflater)     activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    parcaBilgileri = parca;
}

public int getCount() {
    return parcaBilgileri.size();
}

public Parcalar getItem(int position) {
    return parcaBilgileri.get(position);
}

public long getItemId(int position) {
    return position;
}

public View getView(int position, View convertView, ViewGroup parent) {
    View satirView;
    satirView = inflater.inflate(R.layout.parcalar_list, null);
    TextView txtTalepTarihi = (TextView)     satirView.findViewById(R.id.txtTalepTarihi);
    TextView txtParca = (TextView) satirView.findViewById(R.id.txtParca);
    TextView txtMiktar = (TextView)     satirView.findViewById(R.id.txtMiktar);
    TextView txtIadeDurumu = (TextView)     satirView.findViewById(R.id.txtIadeDurumu);
    TextView txtAciklama = (TextView)     satirView.findViewById(R.id.txtAciklama);
    TextView txtSonuc = (TextView) satirView.findViewById(R.id.txtSonuc);
    TextView txtSonucTarihi = (TextView)     satirView.findViewById(R.id.txtSonucTarihi);

    Parcalar bilgi = parcaBilgileri.get(position);

    txtTalepTarihi.setText(bilgi.gettaleptarihi());
    txtParca.setText(bilgi.getparca());
    txtMiktar.setText(bilgi.getmiktar());
    txtIadeDurumu.setText(bilgi.getiadedurumu());
    txtAciklama.setText(bilgi.getaciklama());
    txtSonuc.setText(bilgi.getsonuc());
    txtSonucTarihi.setText(bilgi.getsonuctarihi());

    return satirView;
}
}

感谢您的帮助。

使用 RecyclerView 而不是 ListView，对于 ScrollView 使用 NestedScrollView。它是为这种滚动而设计的。另一件事，给 recyclerView 高度 wrap_content 空白
