Labels are the simplest widgets in android programming. They are used adjacent to other widgets such as fields.
Dealing with labels in Xml.
This is achieved by adding a TextView element to the layout with an android.text property to set the value of the label itself.
TextView Properties of relevance to labels.
- android:typeface: Sets the typeface to use for the label (e.gmonospace)
- android:textStyle: Indicates that the typeface should be made bold(bold), italic (italic), or bold and italic (bold_italic)
- android:textSize: Specifies the size of the font, in one of several measures: sp(scaled pixels), dip(density-independent pixels), px(raw pixels), in(inches), mm(millimeters). The recommend approach is to use sp, and this is appended to the size, such as 12sp.
- android:textColor: Sets the color of the label’s text, in RGB hex format (e.g., #FF0000for red
