Start from scratch to learn android<tablelayout table layouts. 15 .>

Tablelayout is the display of the cell phone's screen in a row, and a row can be multiple controls

And you can set the alignment of the control, and whether it is a shrink line

Let's look at the use of the Tablelayout layout using a single line diagram and a simple example.

Configure using an XML file alone

<?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:shrinkcolumns=" 3 ">// Line three allows row merge <TableRow> <textview android:id= "@+id/text01" android:layout_width=            "Wrap_content" android:layout_height= "wrap_content" android:text= "user name"/> <edittext Android:id= "@+id/edit01" android:layout_width= "wrap_content" android:layout_height= "Wrap_con    Tent "android:ems=" > <requestfocus/> </EditText> </TableRow>            <TableRow> <textview android:id= "@+id/text02" android:layout_width= "Wrap_content" android:layout_height= "wrap_content" android:text= "password"/> <edittext andro Id:id= "@+id/edittext1" AndroId:layout_width= "Wrap_content" android:layout_height= "Wrap_content" android:ems= "a"            Ndroid:inputtype= "Textpassword"/> </TableRow> <tablerow android:gravity= "center" > <button Android:id= "@+id/button" android:layout_width= "wrap_content" android:layout_height= "Wrap_ Content "android:text=" login System "/> </TableRow></TableLayout>

Run

From the above, you can see clearly that the second line of the first line shows two components, the third line shows a component, and sets the effect of alignment in the play.

The dynamic layout is implemented in a way.

Package Com.example.tablelayout;import Android.app.activity;import Android.os.bundle;import android.view.Gravity; Import Android.view.viewgroup;import Android.widget.button;import Android.widget.edittext;import Android.widget.tablelayout;import Android.widget.tablerow;import Android.widget.textview;public class MainActivity Extends Activity {@Overrideprotected void onCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);// Setcontentview (r.layout.tablelayout); Tablelayout layout = new Tablelayout (this);//Create Tablelayout object//Set Tablelayout alignment Tablelayout.layoutparams Tabletlayoutparams = new Tablelayout.layoutparams (viewgroup.layoutparams.match_parent,viewgroup.layoutparams.wrap _content); TableRow tablerow1=new TableRow (this);//Create First row TableRow tablerow2=new TableRow (this);//create second row TableRow tablerow3=new TableRow (this);//Create a third line TextView textview1=new TextView (this);//Create TextView Object Textview1.settext ("username"); EditText edittext1=new EditText (this);//Create EditText Object Tablerow1.addview (TextView1);TextView set to the first line Tablerow1.addview (EDITTEXT1);//edittext set to the first row TextView textview2=new TextView (this);// Create TextView Object Textview2.settext ("password"); EditText edittext2=new EditText (this);//Create EditText Object Tablerow2.addview (TEXTVIEW2);// TextView set to the first line Tablerow2.addview (EDITTEXT2);//edittext set to the second row button Button=new button (this); Button.settext ("Login System") ; tablerow3.setgravity (gravity.center);//set line nine to align Tablerow3.addview (button); Layout.addview (TABLEROW1);// Add the first row of data to the layout Layout.addview (TABLEROW2);//Add the second row of data to the layout Layout.addview (TABLEROW3);// Add the third row of data to the layout Super.setcontentview (Layout,tabletlayoutparams);}}

Dynamic layout can also achieve the effect of XML layout implementation
