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.
compile 'app.youkai.placeholdertextview:library:1.1.1'Note: You might have to add jcenter() to your repositories.
<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.
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.
