Performance issues in a NumberPicker

Navigation
2

I have a NumberPicker that loads approximately 6000 records. When you try it in api > 20 your answer is not more than 2 seconds but when you test it in a api < 19 your answer is 15 seconds or more.

I want to know if there is any way to improve the response time of api < 19 thank you very much.

Try to use: 

mainView.setLayerType(View.LAYER_TYPE_HARDWARE, null);

And this 

android:layerType="hardware"

That forces hardware rendering and forces the GPU to do the drawing work. You'll already tell us if it worked for you or not.

ValueMember and DisplayMember in Java ComboBox? Should I complete this directive or not? php echo dirname (__ FILE__); ?
