when using relativelayout need add additional properties children tell android how want them laid out. have 2 possible options, relativelayout , linearlayout;
relativelayout
note i've missed out other attributes brevity, should still included. critical parts android:layout_below attributes. if don't include them views attached overlapping each other have observed.
<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@android:color/white" > <linearlayout android:id="@+id/atctypelinear" android:layout_width="wrap_content" android:layout_height="wrap_content" > ... </linearlayout> <linearlayout android:id="@+id/mainevoccutionlinear" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/atctypelinear" > ... </linearlayout> <linearlayout android:id="@+id/collisionnearlinear" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/mainevoccutionlinear" > ... </linearlayout> </relativelayout> linearlayout
the other option use linearlayout parent.
<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@android:color/white" > <linearlayout android:id="@+id/atctypelinear" android:layout_width="wrap_content" android:layout_height="wrap_content" > ... </linearlayout> <linearlayout android:id="@+id/mainevoccutionlinear" android:layout_width="wrap_content" android:layout_height="wrap_content" > ... </linearlayout> <linearlayout android:id="@+id/collisionnearlinear" android:layout_width="wrap_content" android:layout_height="wrap_content" > ... </linearlayout> </linearlayout>
