can me?
this xml:
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="center_horizontal" android:orientation="vertical" android:weightsum="1"> <linearlayout android:layout_width="match_parent" android:layout_height="210dp" android:background="@android:color/holo_green_light" android:gravity="center_vertical" android:orientation="vertical" android:weightsum="1"> <edittext android:id="@+id/edittext" android:layout_width="match_parent" android:layout_height="wrap_content" android:ems="10" android:inputtype="textpersonname" android:text="please place me @ top" /> <textview android:id="@+id/textview" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="bottom" android:background="@android:color/background_light" android:text="textview" android:layout_weight="0.19" /> </linearlayout> <linearlayout android:layout_width="match_parent" android:layout_height="248dp" android:layout_weight="0.70" android:background="@color/coloraccent" android:gravity="center_vertical" android:orientation="vertical" android:weightsum="1"> <button android:id="@+id/button" android:layout_width="match_parent" android:layout_height="62dp" android:layout_gravity="top" android:text="button" /> <textview android:id="@+id/textview2" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_weight="0.16" android:background="@android:color/background_light" android:text="please place me @ bottom" /> </linearlayout> </linearlayout> and output:
if linearlayout isn't working, don't force use it.
nested linearlayouts , weights bad performance.
relativelayout (or constraintlayout) naturally meant place things @ anchor points of viewgroups
i assume want text , button centered based on other attributes
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:weightsum="2"> <relativelayout android:layout_width="match_parent" android:layout_height="0dp" android:background="@android:color/holo_green_light" android:layout_weight="1"> <edittext android:id="@+id/edittext" android:layout_width="match_parent" android:layout_height="wrap_content" android:ems="10" android:layout_alignparenttop="true" android:inputtype="textpersonname" android:text="please place me @ top" /> <textview android:id="@+id/textview" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_centerinparent="true" android:background="@android:color/background_light" android:text="textview" /> </relativelayout> <relativelayout android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" android:background="@android:color/holo_red_light" android:orientation="vertical"> <button android:id="@+id/button" android:layout_width="match_parent" android:layout_height="62dp" android:layout_centerinparent="true" android:text="button"/> <textview android:id="@+id/textview2" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignparentbottom="true" android:background="@android:color/background_light" android:text="please place me @ bottom"/> </relativelayout> </linearlayout> alternatively, need android:gravity="bottom" on second linearlayout, views within @ bottom.
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:weightsum="1"> <!-- top gravity --> <linearlayout android:gravity="top" android:layout_width="match_parent" android:layout_height="0dp" android:background="@android:color/holo_green_light" android:orientation="vertical" android:layout_weight="0.5"> <edittext android:layout_width="match_parent" android:layout_height="wrap_content" android:text="please place me @ top"/> <textview android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@android:color/background_light" android:text="textview"/> </linearlayout> <!-- bottom gravity --> <linearlayout android:gravity="bottom" android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="0.50" android:background="@android:color/holo_red_light" android:orientation="vertical"> <button android:layout_width="match_parent" android:layout_height="62dp" android:text="button"/> <textview android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@android:color/background_light" android:text="please place me @ bottom"/> </linearlayout> </linearlayout>
