编程和xml不相等

Question

我想用行填充特定的TableLayout。但是，当我以编程方式执行此操作时，它看起来与我希望的有所不同。下面的示例与列的大小或距离有关，而与背景无关。我找不到错误。

希望你能帮助我。

XML ：（它的外观）：

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

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

    <TableRow
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="50sp"
        android:gravity="center">

        <TextView
            android:layout_height="wrap_content"
            android:layout_weight="0.2"
            android:width="0dp"
            android:background="@drawable/test_drawablew"
            android:text="Text 1"
            android:textAlignment="center" />

        <View

            android:width="0dp"
            android:background="@drawable/test_drawablew"
            android:text="Text 1.1"
            android:textAlignment="center" />

        <View
            android:layout_width="match_parent"

        <TextView

            android:background="@drawable/test_drawablew"
            android:text="Text 1.2"
            android:textAlignment="center" />


    </TableRow>

    <TableRow
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="50sp"
        android:gravity="center">

        <TextView
            android:layout_height="wrap_content"
            android:layout_weight="0.2"
            android:background="@drawable/test_drawablew"
            android:text="Longer Text"
            android:textAlignment="center" />

        <View

            android:background="@android:color/darker_gray" />

        <TextView
            android:layout_height="wrap_content"
            android:layout_weight="0.2"
            android:background="@drawable/test_drawablew"
            android:text="Longer Text"
            android:textAlignment="center" />

        <View

        <TextView
            android:layout_height="wrap_content"
            android:layout_weight="0.2"

            android:text="Longer Text"
            android:textAlignment="center" />


    </TableRow>

</TableLayout>

以编程方式：

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_permission);
    TableLayout tableLayout = findViewById(R.id.permissionTableLayout);

    ArrayList<FlowInformation> flowInformations = getIntent().getParcelableArrayListExtra("flowInformation");

    TableLayout.LayoutParams tableLayoutParams = new TableLayout.LayoutParams();
    tableLayoutParams.height = TableLayout.LayoutParams.WRAP_CONTENT;
    tableLayoutParams.weight = TableLayout.LayoutParams.MATCH_PARENT;
    tableLayoutParams.bottomMargin = (int) getResources().getDimension(R.dimen.marginBottom);

    for (FlowInformation flowInformation : flowInformations) {
        TableRow tableRow = new TableRow(this);
        tableRow.setGravity(Gravity.CENTER);
        tableRow.setLayoutParams(tableLayoutParams);
        tableRow.setId(View.generateViewId());

        addNewTextViewToTableRow(tableRow, flowInformation.source);

        TableRow.LayoutParams viewParams = new TableRow.LayoutParams();
        viewParams.weight = (float) 0.2;
        viewParams.height = (int) getResources().getDimension(R.dimen.fiveDp);
        viewParams.width = TableRow.LayoutParams.MATCH_PARENT;
        View view = new View(this);
        view.setBackgroundColor(Color.RED);
        view.setLayoutParams(viewParams);
        view.setId(View.generateViewId());
        tableRow.addView(view);

        addNewTextViewToTableRow(tableRow, flowInformation.channel);

        viewParams = new TableRow.LayoutParams();
        viewParams.weight = (float) 0.2;
        viewParams.height = (int) getResources().getDimension(R.dimen.fiveDp);
        viewParams.width = TableRow.LayoutParams.MATCH_PARENT;
        view = new View(this);
        view.setBackgroundColor(Color.RED);
        view.setLayoutParams(viewParams);
        view.setId(View.generateViewId());
        tableRow.addView(view);

        addNewTextViewToTableRow(tableRow, flowInformation.target);

        tableLayout.addView(tableRow);
    }
}

public void addNewTextViewToTableRow(final TableRow tableRow, final String text) {
    GradientDrawable background = new GradientDrawable();
    background.setColor(Color.rgb(235, 235, 235));
    background.setStroke(1, Color.rgb(0, 0, 0));
    background.setShape(GradientDrawable.RECTANGLE);

    TableRow.LayoutParams tableRowParams = new TableRow.LayoutParams();
    tableRowParams.weight = (float) 0.2;
    tableRowParams.height = TableLayout.LayoutParams.WRAP_CONTENT;
    tableRowParams.width = (int) getResources().getDimension(R.dimen.nullDp);

    TextView textView = new TextView(this);
    textView.setTextAlignment(View.TEXT_ALIGNMENT_CENTER);
    textView.setBackground(background);
    textView.setText(text);
    textView.setLayoutParams(tableRowParams);
    textView.setId(View.generateViewId());
    tableRow.addView(textView);
}
