Question

我有一个覆盖整个屏幕并包含可变行数的表。

我想知道如何将这些行垂直均匀分布，以便它们占用整个表格的空间。

我已经尝试过layout_weight和weightSum，但它无效。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/LinearLayout01"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

    <TableLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:stretchColumns="0,1,2"
        android:id="@+id/maintable"
        android:weightSum="3" >

        <TableRow 
            android:layout_width="fill_parent"
            android:layout_height="1dp"
            android:layout_weight="1" >
            <TextView
                android:text="text 1_1"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                />

            <TextView
                android:text="text 2_1"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                />

            <TextView
                android:text="text 3_1"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                />
        </TableRow>

        <TableRow

                android:layout_height="wrap_content"
                />

            <TextView
                android:text="text 2_2"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                />

            <TextView
                android:text="text 3_2"
                android:layout_width="fill_parent"

                android:layout_width="fill_parent"
                android:layout_height="wrap_content"

                android:layout_height="wrap_content"
                />
        </TableRow>

    </TableLayout>
</LinearLayout>

Answer 1

您的代码看起来有误，因为您没有为垂直设置“填充父级”约束轴

    <TableRow 
        android:layout_width="fill_parent"
        android:layout_height="1dp" 
        android:layout_weight="1" >

应该是

    <TableRow 
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" 
        android:layout_weight="1" >

Answer 2

请检查以下代码。这将覆盖整个屏幕，表格行均匀

grid_layout.xml

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tableLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

</TableLayout>

grid_layout在代码中填充了文本视图，如下所示

public class GridLayoutActivity extends Activity {
    private static final int NO_OF_ROWS = 5;
    private static final int NO_OF_COLUMS = 5;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.grid_layout);
        TableLayout gridview = (TableLayout) findViewById(R.id.tableLayout);
        for (int rowCnt = 0 ; rowCnt < NO_OF_ROWS; rowCnt++) {
             TableRow row = new TableRow(this);
         TableLayout.LayoutParams tableLayoutLP = new TableLayout.LayoutParams();
         tableLayoutLP.weight = 1;
         row.setLayoutParams(tableLayoutLP);

        for (int column = 0; column < NO_OF_COLUMS; column++) {
        TextView tv = new TextView(this);
        TableRow.LayoutParams tableRowLP = new TableRow.LayoutParams();
        tableRowLP.setMargins(2, 2, 2, 2);
        tableRowLP.weight=1;
        tableRowLP.height = TableRow.LayoutParams.MATCH_PARENT;
        tv.setTextColor(Color.WHITE);
        tv.setGravity(Gravity.CENTER);
        tv.setBackgroundColor(Color.DKGRAY);
        tv.setLayoutParams(tableRowLP);

        tv.setText("YourText");//Add your text here
        row.addView(tv);
        }

        gridview.addView(row);
    }
}

}

在表格内垂直对齐表格行以掩盖整个区域
