All, I'm customizing a city picker, which uses three numberPicker inside,like this:
Its a Chinese province-city-area picker.
The code:
String[] areas = get_from_somewhere();
areaPicker.setDisplayedValues(areas);
I want to reduce the font size,any advice?
Solution: Refer to this
You can extend the default NumberPicker
in your Custom class CustomNumberPicker
for this:
public class CustomNumberPicker extends NumberPicker {
public NumberPicker(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
public void addView(View child) {
super.addView(child);
if(child instanceof EditText) {
((EditText) child).setTextSize(25);
}
}
}
Now replace your current NumberPicker
in xml with CustomNumberPicker
:
<com.pkg.name.CustomNumberPicker
android:id="@+id/number_picker"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
Although technically not changing the font size, the size of the text can be changed by changing the scale of the entire NumberPicker View.
<NumberPicker
android:id="@+id/number_picker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleX=".7"
android:scaleY=".7"/>
