Android UI layout: TableLayout and androidtablelayout

Code List:
Layout file: table_layout.xml

<? Xml version = "1.0" encoding = "UTF-8"?> <TableLayout xmlns: android = "http://schemas.android.com/apk/res/android" android: layout_width = "match_parent" android: layout_height = "match_parent" android: stretchColumns = "1"> <TableRow> <TextView android: gravity = "right" android: textStyle = "bold" android: padding = "3dip" android: text = "User name:"/> <EditText android: id = "@ + id/username" android: padding = "3dip" android: scrollHorizontally = "true"/> </TableRow> <TextView android: gravity = "right" android: textStyle = "bold" android: padding = "3dip" android: text = "User Password:"/> <EditText android: id = "@ + id/password" android: padding = "3dip" android: password = "true"/> </TableRow> <TableRow android: gravity = "right"> <Button android: id = "@ + id/cancel" android: text = "cancel"/> <Button android: id = "@ + id/login" android: text = "login"/> </TableRow> </TableLayout>

In the preceding layout code, there are three rows, namely three TableRow. Each TableRow contains two cells.
The TableLayout label defines a table layout (TableLayout ).
The TableRow label defines a row in the table layout. Some components can be freely added to each line. For example, we have added the button component and the edit box component.

Java source code file: TableLayoutActivity. java

package com.rainsong.layoutdemo;import android.app.Activity;import android.os.Bundle;public class TableLayoutActivity extends Activity{    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState)    {        super.onCreate(savedInstanceState);        setContentView(R.layout.table_layout);    }}

What should I do if the layout of android tablelayout is insufficient for the screen ???

How to set the height of tablelayout, whether to use android: layout_height = "fill_parent ";
In addition, whether tablelayout is embedded in LinearLayout. if so, whether the height of LinearLayout is also android: layout_height = "fill_parent ".
As long as the height of tablelayout is set to full parent control, the parent control is also set to tablelayout to be full screen.
Then, some of your TableRow does not use android: layout_weight = "1". Add the weight.

TableLayout layout in android

<TableRow>
<Button android: id = "@ + id/btndel" android: layout_width = "100dp" android: layout_height = "wrap_content" android: layout_weight = "1" android: text = "delete"/>
<Button android: id = "@ + id/btnupdate" android: layout_width = "50dp" android: layout_height = "wrap_content" android: layout_weight = "1" android: text = "Update"/>
<Button android: id = "@ + id/btnupdate" android: layout_width = "70dp" android: layout_height = "wrap_content" android: layout_weight = "1" android: text = "Update"/> </TableRow>
