项目需要纵向滚轮控件和横向滚轮控件
纵向滚轮控件:AndroidWheelDemo、AndroidWheel
横向滚轮控件:android 滚轮刻度尺的实现、android自己写的类似刻度尺的东西。
纵向滚轮控件如下:
修改滚轮控件的布局可以在src/kankan/wheel/widget/WheelView.java和/res/drawable/wheel_val.xml
和/res/layout/wheel_text_item.xml和\res\layout\tempitem.xml和src\kankan\wheel\demo\CitiesActivity.java
修改控件字体大小、颜色:
CitiesActivity.java
/** * Adapter for countries */ private class CountryAdapter extends AbstractWheelTextAdapter { // Countries names ArrayList list; protected CountryAdapter(Context context,ArrayList list) { super(context, R.layout.tempitem, NO_RESOURCE); this.list = list; setItemTextResource(R.id.tempValue); } // Countries flags private int flags =R.drawable.tem_unit_dialog; @Override public View getItem(int index, View cachedView, ViewGroup parent) { View view = super.getItem(index, cachedView, parent); ImageView img = (ImageView) view.findViewById(R.id.tempImag); img.setImageResource(flags); return view; } @Override public int getItemsCount() { return list.size(); } @Override protected CharSequence getItemText(int index) { return list.get(index)+""; } }
tempitem.xml
xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:gravity="center"
>
<TextView
android:id="@+id/tempValue"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="23dp"
android:textColor="#ff6347"
/>
<ImageView
android:id="@+id/tempImag"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/tem_unit_dialog"/>
LinearLayout>
wheel_text_item.xml
xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20dp"
android:lines="1"
android:textStyle="bold"
android:textColor="#FF111111"
android:layout_gravity="right" />
修改控件布局、背景:WheelView.java和wheel_val.xml
wheel_val.xml
xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:startColor="#70222222"
android:centerColor="#70222222"
android:endColor="#70EEEEEE"
android:angle="90" />
<stroke android:width="1dp" android:color="#F0FF63" />
shape>
wheel_bg.xml
xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<gradient
android:startColor="#33CC99"
android:centerColor="#33CC99"
android:endColor="#33CC99"
android:angle="90" />
<stroke android:width="1dp" android:color="#FF3399" />
shape>
item>
<item android:left="4dp" android:right="4dp" android:top="1dp" android:bottom="1dp">
<shape android:shape="rectangle">
<gradient
