android - Build Custom View with allways same Layout -

-

i have made own layout button. normaly create view this:

layoutinflater inflater = layoutinflater.from(getactivity()); mybutton = inflater.inflate(r.layout.mybutton, null, false);

now idea class mybutton extends view , not have write these lines each button. how can bring these 2 lines in mybutton constructor? can't write:

public mybutton(context c) {     = inflater.inflate(r.layout.mybutton, null, false); }

how can build custom view has allways same layout can build new mybutton preloaded layout this:

mybutton mybutton = new mybutton();

this layout want use mybutton:

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/cell_shape" android:orientation="vertical" android:paddingbottom="@dimen/paddingbottom" android:paddingleft="@dimen/paddinghorizontal" android:paddingright="@dimen/paddinghorizontal" android:paddingtop="@dimen/paddingtop" >  <textview     android:id="@+id/fach"     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_marginbottom="@dimen/margintop"     android:text=""     android:textappearance="?android:attr/textappearancemedium"     android:textstyle="bold" />  <linearlayout     android:layout_width="match_parent"     android:layout_height="wrap_content" >      <textview         android:id="@+id/klasse"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_marginright="@dimen/margintop"         android:text="" />      <textview         android:id="@+id/raum"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:gravity="right"         android:text="" /> </linearlayout>

you can still reuse button xml practically independent of layout. create button.xml in drawable folder define button properties. example of button layout has custom custom corner radius , color gradient (you need define these colors in res/values/colors.xml,of course):

<item android:state_pressed="true">     <shape>         <gradient             android:startcolor="@color/pressed1"             android:endcolor="@color/pressed2"             android:angle="90" />         <corners android:radius="4dp" />         <padding             android:left="10dp"             android:top="10dp"             android:right="10dp"             android:bottom="10dp" />     </shape> </item>  <item android:state_focused="true">     <shape>         <gradient             android:endcolor="@color/focused1"             android:startcolor="@color/focused2"             android:angle="270" />         <corners android:radius="4dp" />         <padding             android:left="10dp"             android:top="10dp"             android:right="10dp"             android:bottom="10dp" />     </shape> </item>  <item>     <shape>         <gradient             android:startcolor="@color/default1"             android:endcolor="@color/default2"             android:angle="90" />         <corners android:radius="4dp" />         <padding             android:left="20dp"             android:top="10dp"             android:right="20dp"             android:bottom="10dp" />     </shape> </item>

whenever need reuse it, can create button view usual:

        <button             android:id="@id/button1"             android:layout_width="wrap_content"             android:background="@drawable/button"             android:text="@string/button_text">         </button>
