I am trying to add a button to title bar but I couldn't succeed. I have read many articles about this but they all explain the way that doesn't fit my situation. I am using ScrollView to make the screen scrollable. but articles suggest me to use linear layout. How can I make it scrollable and have a button on the title bar?
here is my XML
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#C0C0C0"
android:id="@+id/sw_layout">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="horizontal"
android:id="@+id/ln_layout">
<TableLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft=<"@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin" >
.........................
.........................
.........................
</TableLayout>
</LinearLayout>
</ScrollView>
And in my MainActivity, I have this code....
LinearLayout ln = (LinearLayout) getWindow().findViewById(R.id.ln_layout);
Button btn = new Button(this);
btn.setText("Test");
ln.addView(btn);
But this doesn't display anything and it doesn't give me any error. Please give me an idea. how can I add the button to title bar?
