How To Add Multiple Buttons To A Row Dynamically In Android

Does anybody know how to add multiple buttons to a table row dynamically in Android?

Solution 1:

You can try this and see if it's what your are looking for.

main.xml:

<?xml version="1.0" encoding="utf-8"?><LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:id="@+id/layout"android:orientation="vertical"android:layout_width="fill_parent"android:layout_height="fill_parent"
><Buttonandroid:text="Button"android:id="@+id/button1"android:layout_height="wrap_content"android:layout_width="wrap_content"/><TableLayoutandroid:id="@+id/tableLayout1"android:layout_height="wrap_content"android:layout_width="fill_parent" /></LinearLayout>

Your Activity class:

publicclassmainActivityextendsActivityimplementsOnClickListener {
    /** Called when the activity is first created. */@OverridepublicvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView( R.layout.main );
        Buttonb= (Button) findViewById( R.id.button1 );
        b.setOnClickListener( this );
    }

    @OverridepublicvoidonClick(View v) {   
        TableLayouttable= (TableLayout) findViewById( R.id.tableLayout1 );

        intbuttonsInRow=0;
        intnumRows= table.getChildCount();
        TableRowrow=null;
        if( numRows > 0 ){
            row = (TableRow) table.getChildAt( numRows - 1 );
            buttonsInRow = row.getChildCount();         
        }

        if( numRows == 0 || buttonsInRow == 3 ){
            row = newTableRow( this );
            table.addView( row );
            buttonsInRow = 0;
        }
        if( buttonsInRow < 3 ){
            Buttonb=newButton( this );
            row.addView( b, 100, 50 );
        }
    }
}

Hope it helps.

Solution 2:

Here layout is a TableLayout.If you want to add a row dynamically and buttons in that row can use the follwoing code

TableRow tr1=newTableRow(this);
                    Button tv=newButton(this);
                tv.setText("");
                tr1.addView(tv,250,30);
                Button tv1=newButton(this);
                tv1.setText("");
                tr1.addView(tv1,100,30);
                layout.addView(tr1);

If you already have row in the layout then just fetch the row and add buttons to the row

After searching for 30 sec I found http://www.warriorpoint.com/blog/2009/07/01/android-creating-tablerow-rows-inside-a-tablelayout-programatically - this should help you, just change TextViews to Buttons.
