一手遮天 Android - view(选择类): NumberPicker 样式
示例如下:
/view/selection/NumberPickerDemo2.java
/**
* NumberPicker - 滑动选择框
*
* 本例演示如何自定义 NumberPicker 的样式(需要继承 NumberPicker 以便实现自定义逻辑,详见:NumberPickerCustom.java)
*/

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import com.webabcd.androiddemo.R;
import com.webabcd.androiddemo.utils.Helper;
public class NumberPickerDemo2 extends AppCompatActivity {
// 自定义的 NumberPicker
private NumberPickerCustom _numberPicker1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view_selection_numberpickerdemo2);
_numberPicker1 = (NumberPickerCustom)findViewById(R.id.numberPicker1);
sample();
}
private void sample() {
_numberPicker1.setMinValue(0);
_numberPicker1.setMaxValue(24);
_numberPicker1.setValue(12);
// 设置 NumberPicker 的分隔线的颜色
_numberPicker1.setDividerColor(getResources().getColor(R.color.blue));
// 设置 NumberPicker 的分隔线的粗细
_numberPicker1.setDividerHeight(Helper.dp2px(this, 5));
}
}
