First view above / overlapping second in LinearLayout
Is it possible to show the first view in a LinearLayout overlapping the second?
I would like to layout my views like so:
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_alignParentRight="true" >
<TextView
android:id="@+id/firstTextView"
android:layout_width="wrap_content"
android:layout_height="wrapContent" />
<TextView
android:id="@+id/secondTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
But I need my first view from the layout, firstTextView, to be placed on top of (overlapping) secondTextView. Is this possible? I am using the LinearLayout because I'm also playing with the margins to get an overlapping effect.
What worked for me and probably will work for you is that:
- Wrap your 2 TextViews with RelativeLayout instead of LinearLayout and set android:clipChildren="false". This will prevent the overlapping portion from being clipped.
- Layout the 2nd TextView below the first TextView
- In the code, call bringToFront() on the first TextView. By default, the first textview is drawn first and will be below the second textview. Calling bringToFront() will change that order.
So the layout can be something like this:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:clipChildren="false">
<TextView
android:id="@+id/firstTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#00000000"
android:text="First View" />
<TextView
android:id="@+id/secondTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/firstTextView"
android:background="#00000000"
android:layout_marginTop="-13dp"
android:text="Second View"/>
</RelativeLayout>
and:
TextView firstTextView = (TextView)findViewById(R.id.firstTextView);
firstTextView.bringToFront();
If all you want is to overlap the two views vertically, then use this XML:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="@+id/firstTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#00000000"
android:text="First View" />
<TextView
android:id="@+id/secondTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#00000000"
android:layout_marginTop="-13dp"
android:text="Second View"/>
</LinearLayout>
Or you can stick with Linear Layout, but place a RelativeLayout within it, as a child. You can than place your TextViews withing the RelativeLayout, so they'll inheret properties from RelativeLayout. You can then still use your LinearLayout for other views. http://developer.android.com/reference/android/widget/RelativeLayout.html
