第十一天的PickerView和AutoSize

PickerView是什么

仿iOS的PickerView控件,带有3D圆弧效果,并封装了时间选择和选项选择这两种选择器。

导包

implementation 'com.contrarywind:Android-PickerView:4.1.9'

用法

XML中的布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <com.contrarywind.view.WheelView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/wheel"></com.contrarywind.view.WheelView>

</LinearLayout>

在代码中使用

package com.fenghongzhang.day011;

import android.os.Bundle;
import android.util.Log;

import androidx.appcompat.app.AppCompatActivity;

import com.bigkoo.pickerview.adapter.ArrayWheelAdapter;
import com.contrarywind.listener.OnItemSelectedListener;
import com.contrarywind.view.WheelView;

import java.util.ArrayList;
import java.util.List;

public class MainActivity extends AppCompatActivity {
    private WheelView wheel;

    private static final String TAG = "MainActivity";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        wheel = (WheelView) findViewById(R.id.wheel);
        //数据源
        final List<String> list = new ArrayList<>();
        list.add("我的中国心");
        list.add("北国之春");
        list.add("鹿港小镇");
        wheel.setOnItemSelectedListener(new OnItemSelectedListener() {
            @Override
            public void onItemSelected(int index) {
                Log.i(TAG, "onItemSelected: "+list.get(index));
            }
        });
        //数组适配器
        ArrayWheelAdapter arrayWheelAdapter = new ArrayWheelAdapter(list);
        //设置适配器
        wheel.setAdapter(arrayWheelAdapter);
    }
}
