You CAN do this with gradle. I’ve made a demo project showing how. The trick is to use gradle’s ability to merge multiple resource folders, and set the res folder as well as the nested subfolders in the sourceSets block. The quirk is that you can’t declare a container resource folder before you declare that … Read more
The modern way to do this is to have a ConstraintLayout and constrain the bottom of the view to the bottom of the ConstraintLayout with app:layout_constraintBottom_toBottomOf=”parent” The example below creates a FloatingActionButton that will be aligned to the end and the bottom of the screen. <android.support.constraint.ConstraintLayout xmlns:android=”http://schemas.android.com/apk/res/android” xmlns:app=”http://schemas.android.com/apk/res-auto” xmlns:tools=”http://schemas.android.com/tools” android:layout_height=”match_parent” android:layout_width=”match_parent”> <android.support.design.widget.FloatingActionButton android:layout_height=”wrap_content” android:layout_width=”wrap_content” app:layout_constraintBottom_toBottomOf=”parent” … Read more
With layout_weight you can specify a size ratio between multiple views. E.g. you have a MapView and a table which should show some additional information to the map. The map should use 3/4 of the screen and table should use 1/4 of the screen. Then you will set the layout_weight of the map to 3 … Read more
I discovered that this can all be done in one file fairly easily. Put something like the following code in a file named custom_button.xml and then set background=”@drawable/custom_button” in your button view: <?xml version=”1.0″ encoding=”utf-8″?> <selector xmlns:android=”http://schemas.android.com/apk/res/android”> <item android:state_pressed=”true” > <shape> <gradient android:startColor=”@color/yellow1″ android:endColor=”@color/yellow2″ android:angle=”270″ /> <stroke android:width=”3dp” android:color=”@color/grey05″ /> <corners android:radius=”3dp” /> <padding android:left=”10dp” … Read more
It can be achieved if you are using a string resource xml file, which supports HTML tags like <b></b>, <i></i> and <u></u>. <resources> <string name=”your_string_here”><![CDATA[This is an <u>underline</u>.]]></string> </resources> If you want to underline something from code use: TextView textView = (TextView) view.findViewById(R.id.textview); SpannableString content = new SpannableString(“Content”); content.setSpan(new UnderlineSpan(), 0, content.length(), 0); textView.setText(content);
You can set a shape drawable (a rectangle) as background for the view. <TextView android:text=”Some text” android:background=”@drawable/back”/> And rectangle drawable back.xml (put into res/drawable folder): <shape xmlns:android=”http://schemas.android.com/apk/res/android” android:shape=”rectangle” > <solid android:color=”@android:color/white” /> <stroke android:width=”1dip” android:color=”#4fa5d5″/> </shape> You can use @android:color/transparent for the solid color to have a transparent background.
