PlaceholderTextView

A custom TextView which shows placeholder lines given a sample text when it has no text set

You give it some sample text, it calculates and draws equivalent placeholder lines. You then give it some text ( .setText(...)), it automatically gets rid of the placeholder and shows your text.

Download

Usage

 <app.youkai.placeholdertextview.PlaceholderTextView

 android:layout_width="match_parent"

 android:layout_height="wrap_content"

 android:textColor="@color/my_text_color"

 android:lines="2"

 android:maxLines="3"

 app:ptv_placeholderColor="@color/my_placeholder_color"

 app:ptv_sampleText="Lorem ipsum dolor sit amet" />

 placeholderTextView.setSampleText("Lorem ipsum dolor sit amet");

  int originalPlaceholderColor = placeholderTextView.getPlaceholderColor();

  placeholderTextView.setPlaceholderColor(getColor(R.colod.my_placeholder.color));

Yes, PlaceholderTextView does respect android:lines and android:maxLines attributes when displaying the placeholder lines.

Theming

By default, PlaceholderTextView uses the text color with 20% alpha. You can use app:ptv_placeholderColor="@color/... or ptv.setPlaceholdercolor(int) to set your own color.
