:fire::fire::fire: App金刚区导航菜单,类似淘宝、QQ音乐等APP导航,方格布局横向多行滑动翻页带滚动条
:fire: APP金刚区导航布局,下方带横向滚动条,很多APP都有使用这种,效果还不错就封装了一下:smile:
整体结构是Recyclerview + 滚动条
:mega:项目基于AndroidX构建,参考迁移指南:AndroidX迁移
Step 1: 项目根目录的build.gradle添加如下配置:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Step 2: app添加依赖:
dependencies {
implementation 'com.github.zaaach:TransformersLayout:x.y.z'
}
Step 1: xml布局文件
<com.zaaach.transformerslayout.TransformersLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffffff"
app:tl_spanCount="5"
app:tl_lines="2"
app:tl_pagingMode="true"
app:tl_scrollbarWidth="72dp"
app:tl_scrollbarHeight="4dp"
app:tl_scrollbarRadius="2dp"
app:tl_scrollbarMarginTop="6dp"
app:tl_scrollbarMarginBottom="6dp"
app:tl_scrollbarThumbFixedMode="true"
app:tl_scrollbarThumbFixedWidth="12dp"
app:tl_scrollbarTrackColor="#f0f0f0"
app:tl_scrollbarThumbColor="#FFC107"/>
Step 2: 自定义ViewHolder,第三步需要用到
public class NavAdapterViewHolder extends Holder<Nav> {
private ImageView icon;
private TextView text;
NavAdapterViewHolder(@NonNull View itemView) {
super(itemView);
}
@Override
protected void initView(View itemView) {
icon = itemView.findViewById(R.id.iv_menu_icon);
text = itemView.findViewById(R.id.tv_menu_text);
}
@Override
public void onBind(Context context, List<T> list, @Nullable Nav data, int position) {
text.setText(data.getText());
Glide.with(context)
.asBitmap()
.fitCenter()
.diskCacheStrategy(DiskCacheStrategy.ALL)
.placeholder(R.drawable.default_place_holder)
.load(data.getUrl())
.into(icon);
}
}
Step 3: java代码中调用
List<Nav> navList = DataFactory.loadData();
TransformersLayout<Nav> header = findViewById();
//options可选配置,会覆盖xml里的属性
TransformersOptions options = new TransformersOptions.Builder()
.lines(2)
.spanCount(5)
.pagingMode(true)
.scrollBarWidth(Util.dp2px(this, 40))
.scrollBarHeight(Util.dp2px(this, 3))
.scrollBarRadius(Util.dp2px(this, 3) / 2f)
.scrollBarTopMargin(Util.dp2px(this, 6))
.scrollBarBottomMargin(Util.dp2px(this, 6))
.scrollBarTrackColor(Color.parseColor("#e5e5e5"))
.scrollBarThumbColor(Color.parseColor("#658421"))
.scrollBarThumbFixedMode(true)
.scrollBarThumbWidth(Util.dp2px(this, 12))
.build();
header.apply(options)//options可为null
.addOnTransformersItemClickListener(new OnTransformersItemClickListener() {
@Override
public void onItemClick(int position) {
showToast();
}
})
.load(navList, new TransformersHolderCreator<Nav>() {
@Override
public Holder<Nav> createHolder(View itemView) {
return new NavAdapterViewHolder(itemView);
}
@Override
public int getLayoutId() {
return R.layout.item_nav_list;//第二步使用的布局
}
});
:smirk:Good luck!!!
