i have removed weight property , removed android:layout_width="0dp". have insert android:layout_width="wrap_content" instead. problem solved.

<tablelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     tools:context=".tablelayoutactivity"     android:orientation="vertical"    > <tablerow>     <button android:id="@+id/firstbutton"         android:layout_width="wrap_content"         android:layout_height="wrap_content"          android:text="@string/myfirstbtn"/>      <button android:id="@+id/thirdbutton"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="@string/mythirdbtn"/>     <button android:id="@+id/fourthbutton"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="@string/myfourthbtn"/> </tablerow>     <tablerow>         <button android:id="@+id/secbutton"             android:layout_column="1"             android:text="@string/mysecbtn"/>     </tablerow> </tablelayout>
