import android.content.Context; import android.graphics.drawable.ColorDrawable; import android.util.AttributeSet; import android.view.View; import android.view.ViewGroup; import android.widget.EditText; import android.widget.NumberPicker; import java.lang.reflect.Field; public class TextConfigNumberPicker extends NumberPicker {public TextConfigNumberPicker(Context context) { super(context); }public TextConfigNumberPicker(Context context, AttributeSet attrs) { super(context, attrs); }public TextConfigNumberPicker(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); }@Override public void addView(View child) { this.addView(child, null); }@Override public void addView(View child, ViewGroup.LayoutParams params) { this.addView(child, 0, params); }@Override public void addView(View child, int index, ViewGroup.LayoutParams params) { super.addView(child, index, params); updateView(child); }private void updateView(View view) { if (view instanceof EditText) { //设置通用(默认)文字的颜色和大小 ((EditText) view).setTextColor(getResources().getColor(R.color.whiter)); ((EditText) view).setTextSize(13); } try { //设置分割线大小颜色 Field mSelectionDivider = this.getFile("mSelectionDivider"); mSelectionDivider.set(this, new ColorDrawable(getResources().getColor(R.color.pickline))); mSelectionDivider.set(this, 10); } catch (Exception e) { e.printStackTrace(); } }//反射获取控件 mSelectionDivider mInputText当前选择的view public Field getFile(String fieldName) { try { //设置分割线的颜色值 Field pickerFields = NumberPicker.class.getDeclaredField(fieldName); pickerFields.setAccessible(true); return pickerFields; } catch (Exception e) { e.printStackTrace(); }return null; }//设置选中控件的style注意一点要在setOnValueChangedListener或 setOnScrollChangeListener,setOnScrollListener中调 // 用picker.performClick(); 两种情况动画效果不同 //同时注意他的代用位置要在当前控件初始化之后否则获得不了 public void setMInputStyle(Float size) { Field mInputText = this.getFile("mInputText"); try { ((EditText) mInputText.get(this)).setTextSize(size); } catch (IllegalAccessException e) { e.printStackTrace(); } } }

注意设置选中控件的style 要在当前控件初始化之后 ,用法:

TextConfigNumberPicker numberPicker = dialog.findViewById(R.id.np); numberPicker.setMInputStyle(16f); //setOnValueChangedListener或 setOnScrollChangeListener,setOnScrollListener numberPicker.setOnValueChangedListener(new NumberPicker.OnValueChangeListener() { @Override public void onValueChange(NumberPicker picker, int oldVal, int newVal) { picker.performClick(); //刷新选中状态 } });
