子可滾動表格布局未顯示在我的警報對話框中。為什么？

我正在嘗試在我的應用程式的自定義警報對話框中顯示資料表。

我的自定義警報 xml：

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:stretchColumns="*">

    <!--Only this row shows in my dialog box-->

    <TableRow
        android:padding="5dp">
        <TextView
            android:padding="5dp"
            android:text="Page"/>
        <TextView
            android:padding="5dp"
            android:text="ENo"/>
        <TextView
            android:padding="5dp"
            android:text="QNo"/>
        <TextView
            android:padding="5dp"
            android:text="P_date"/>
        <TextView
            android:padding="5dp"
            android:text="P_read"/>
        <TextView
            android:padding="5dp"
            android:text="C_read"/>
    </TableRow>

    <!--This row does not show-->

    <TableRow>
        <ScrollView
            android:layout_width="match_parent"
            android:layout_height="match_parent">
            <TableLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:id="@ id/meter_details"
                android:stretchColumns="*">
            </TableLayout>
        </ScrollView>
    </TableRow>
</TableLayout>

我填充子表的java代碼（id：meter_details）：

AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
AlertDialog ad;
builder.setIcon(R.drawable.ic_power);
builder.setView(R.layout.meter_entry_dialog);

builder.setTitle("Meter entry");
builder.setMessage("Please enter the details");

Context dialogContext = builder.getContext();
LayoutInflater inflater = LayoutInflater.from(dialogContext);
View dialogView = inflater.inflate(R.layout.meter_entry_dialog, null);

TableLayout tbl = dialogView.findViewById(R.id.meter_details);

for(int i=0;i<arr.size();i  ){
   TableRow row = new TableRow(getContext());
   row.setBackground(getResources().getDrawable(R.drawable.border));
   TextView pg = new TextView(getContext());
   TextView empno = new TextView(getContext());
   TextView qtrno = new TextView(getContext());
   TextView prev_date = new TextView(getContext());
   EditText prev_read = new EditText(getContext());
   EditText curr_read = new EditText(getContext());

   try {
      pg.setText(arr.get(i).get(7).toString());
      empno.setText(arr.get(i).get(1).toString());
      qtrno.setText(arr.get(i).get(2).toString());
      prev_date.setText(arr.get(i).get(5).toString());
      prev_read.setText(arr.get(i).get(4).toString());

      row.addView(pg);
      row.addView(empno);
      row.addView(qtrno);
      row.addView(prev_date);
      row.addView(prev_read);
      row.addView(curr_read);

      tbl.addView(row);
  } catch (JSONException e) {
      e.printStackTrace();
  }
}
builder.setPositiveButton("Submit", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialogInterface, int i) {}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialogInterface, int i) {
         dialogInterface.dismiss();
    }
});
builder.setCancelable(false);
ad = builder.create();
ad.show();
WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams();
layoutParams.copyFrom(ad.getWindow().getAttributes());
layoutParams.width = WindowManager.LayoutParams.MATCH_PARENT;
layoutParams.height = WindowManager.LayoutParams.MATCH_PARENT;
ad.getWindow().setAttributes(layoutParams);

只有我的父表格布局的第一行顯示在我的alertdialog. 我的其余資料（我從陣列中獲取并動態創建表行并存盤它們）沒有顯示。

我不知道為什么會這樣。我什至檢查了我的arr，它具有所需的所有值。請幫我

您應該將充氣設定dialogView為對話框的視圖。
將此行更改builder.setView(R.layout.meter_entry_dialog);為并在' 初始化builder.setView(dialogView);后將其移動。 此外，您可以使用 布局充氣器的方法。dialogView
getContext()

AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
AlertDialog ad;
builder.setIcon(R.drawable.ic_power);

builder.setTitle("Meter entry");
builder.setMessage("Please enter the details");

LayoutInflater inflater = LayoutInflater.from(getContext());

View dialogView = inflater.inflate(R.layout.meter_entry_dialog, null);
builder.setView(dialogView);

TableLayout tbl = dialogView.findViewById(R.id.meter_details);
...

我認為您應該為 ScrollView 設定固定高度。
