Question

我希望我的表能够在整个屏幕上显示列和行之间的间距。我在java中动态创建我的行，具体取决于玩家的数量。在java代码中我添加属性，以便表占据整个屏幕。但我无法实现它。下面附有我的代码和xml文件。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="views.controllers.RoundInfo">

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:onClick="addRound"
        android:text="@string/addround" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="20dp"
        android:text="@string/roundinfo"
        android:textSize="30sp" />

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="none">

        <HorizontalScrollView
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <TableLayout
                android:id="@+id/maintable"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" />

        </HorizontalScrollView>

    </ScrollView>


</LinearLayout>


    public void addData() {
            numOfPlayers = currentRound.getPlayers().size();
            row = new String[numOfPlayers];
            for (int i = 0; i < numOfPlayers; i++) {
                row[i] = currentRound.getPlayers().get(i).getPlayer().getName();
            }
            col = new String[]{"Winner", "Seen", "Less", "Points"}; // get from database

            int rowCount = row.length;

            for (int i = 0; i <= rowCount; i++) {
                TableRow tableRow = new TableRow(this);
                TableLayout.LayoutParams tableRowParams=
                        new TableLayout.LayoutParams
                                (TableLayout.LayoutParams.MATCH_PARENT,TableLayout.LayoutParams.MATCH_PARENT);

                int leftMargin=10;
                int topMargin=2;
                int rightMargin=10;
                int bottomMargin=2;

                tableRowParams.setMargins(leftMargin, topMargin, rightMargin, bottomMargin);

                tableRow.setLayoutParams(tableRowParams);
                // create tableRow
                for (int j = 0; j <= 4; j++) {
                    //create textView

                    TextView textView = new TextView(this);
                    textView.setGravity(Gravity.CENTER);
                    CheckBox checkBox = new CheckBox(this);
                    EditText point = new EditText(this);
                    if (i == 0 && j == 0) {
                        textView.setText(" ");
                        tableRow.addView(textView);
                    } else if (i > 0 && j == 0) {
                        textView.setText(row[i - 1]); // Player Header
                        tableRow.addView(textView);
                    } else if (i == 0 && j != 0) {
                        textView.setText(col[j - 1]); //Game Header
                        tableRow.addView(textView);

如果您希望您的桌子在屏幕上占用尽可能多的空间，请删除其父母的边距和填充

例如根布局如何填充，删除此

android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"

如果您重新考虑如何实施表格，这可以变得更容易。

在您的布局中空白TableLayout，其中包含您希望在UI中使用的空间，

为TableRow填充TableLayout的单独布局，您将对LayoutInflator行使用此单独布局，并填充所需的行数

 LayoutInflater layoutInflater = LayoutInflater.from(getApplicationContext());
 layoutInflater.inflate(R.layout.your_single_row, parent, false);

这将返回一个View对象，您可以将其添加到TableLayout

tableLayout.addView("you view will come here which you get from the inflater");

表在android中占据整个屏幕
