Question

我创建了以下布局。

<TableLayout android:layout_width="fill_parent"
        android:layout_height="wrap_content" 
        android:orientation="horizontal"
        >
        <TableRow>


<TextView android:layout_width="fill_parent"
        android:layout_height="wrap_content" android:text="Post As" />


<Spinner 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/ddlPostAs"
        />
        </TableRow>
        <TableRow>
<TextView android:layout_width="fill_parent"
        android:layout_height="wrap_content" android:text="Expires In" />

<Spinner 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:id="@+id/ddlExpiryOn"

        />
</TableRow>
</TableLayout>

其中android微调器根据数据改变其宽度。我想阻止它。

任何人都可以指导我如何实现这个目标吗？

任何帮助都会得到满足。

Answer 1

根据屏幕宽度固定宽度。

 DisplayMetrics d = new DisplayMetrics(); 
 getWindow().getWindowManager().getDefaultDisplay().getMetrics(d); 
 int wdt = d.widthPixels;
 ddlpostas.getLayoutParams().width = wdt - 120;
 ddlexpiryon.getLayoutParams().width = wdt - 120;

您可以在import java.awt.Color; import java.awt.EventQueue; import java.awt.Font; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTabbedPane; import javax.swing.JTable; import javax.swing.ListSelectionModel; import javax.swing.border.BevelBorder; import javax.swing.border.SoftBevelBorder; import javax.swing.table.DefaultTableModel; public class GUIMain{ private JFrame frmKeyoperateTestframework; public JTable tableBefore; public JTable tableMainTest; public JTable tableAfter; public JTabbedPane tabbedPane; public JScrollPane scrollTables; /** * Launch the application. */ public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { public void run() { try { GUIMain window = new GUIMain(); window.frmKeyoperateTestframework.setVisible(true); } catch (Exception e) { e.printStackTrace(); } } }); } /** * Create the application. */ public GUIMain() { initialize(); } /** * Initialize the contents of the frame. */ private void initialize() { frmKeyoperateTestframework = new JFrame(); frmKeyoperateTestframework.setResizable(false); frmKeyoperateTestframework.getContentPane().setBackground(Color.WHITE); frmKeyoperateTestframework.setFont(new Font("Carlito", Font.PLAIN, 14)); frmKeyoperateTestframework.setTitle("GUI"); frmKeyoperateTestframework.setBounds(100, 100, 865, 584); frmKeyoperateTestframework.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frmKeyoperateTestframework.getContentPane().setLayout(null); tabbedPane = new JTabbedPane(JTabbedPane.TOP); tabbedPane.setBorder(new SoftBevelBorder(BevelBorder.LOWERED, null, null, null, null)); tabbedPane.setFont(new Font("Carlito", Font.PLAIN, 13)); tabbedPane.setBackground(Color.WHITE); tabbedPane.setTabLayoutPolicy(JTabbedPane.SCROLL_TAB_LAYOUT); scrollTables = new JScrollPane(); scrollTables.setBounds(446, 50, 397, 490); scrollTables.setViewportView(tabbedPane); frmKeyoperateTestframework.getContentPane().add(scrollTables); // "5" to show, that only data rows are displayed DefaultTableModel tableModel = new DefaultTableModel(new String[]{"Client", "Action", "Location", "Value"}, 5); tableBefore = new JTable(); tableBefore.setName("tableBefore"); tableBefore.setSelectionMode(ListSelectionModel.SINGLE_SELECTION); tableBefore.setModel(tableModel); tabbedPane.addTab("Before", null, tableBefore, null); tableBefore.setFont(new Font("Carlito", Font.PLAIN, 13)); tableBefore.setFocusable(false); tableMainTest = new JTable(); tableMainTest.setName("tableMainTest"); tableMainTest.setSelectionMode(ListSelectionModel.SINGLE_SELECTION); tableMainTest.setFont(new Font("Carlito", Font.PLAIN, 13)); tableMainTest.setFocusable(false); tableMainTest.setModel(tableModel); tabbedPane.addTab("Main", null, tableMainTest, null); tabbedPane.setEnabledAt(1, true); tableAfter = new JTable(); tableAfter.setName("tableAfter"); tableAfter.setModel(tableModel); tableAfter.setSelectionMode(ListSelectionModel.SINGLE_SELECTION); tabbedPane.addTab("After", null, tableAfter, null); tableAfter.setFont(new Font("Carlito", Font.PLAIN, 13)); tableAfter.setFocusable(false); tabbedPane.setSelectedComponent(tableMainTest); } }上使用“android：weightSum”来调整屏幕上固定的宽度。

示例：

<TableRow>

通过此代码，您的微调器宽度将设置为TableRow宽度的一半。

根据您的要求更改android：weightSum和android：layout_weight的值。

android spinner宽度问题？
