#2018-07-14 更新内容，增加文件管理、网路判断和方法传递上下文
android 开发UI 一些常用的控件，我在android应用开发的过程中遇到的常用的自定义控件和必用的工具类
1、按字母排序功能 2、自定义密码 3、滑轮菜单 4、相册选择图片 5、手势放大缩小 6、自定义标签 7、列表下拉刷新上拉加载更多
compile 'com.wheel:tools:1.1.0'
此功能为应用的常用的类似朋友圈功能中选择相册图片的多选功能，包括图片多选、预览、删除。 此功能为封装好的调用
IntentUtil.startActivity(this, AlbumAllActivity.class);
下一步就是一系列操作了，等选择图片成功以后 所有的图片都封装在
public static ArrayList<ImageItem> tempSelectBitmap = new ArrayList<ImageItem>(); // 选择的图片的临时列表
public class ImageItem implements Serializable {//图片的对象属性
private static final long serialVersionUID = 1L;
public String imageId;
public String thumbnailPath;
public String imagePath;
private Bitmap bitmap;
public boolean isSelected = false;
}
ImageItem imageItem=Bimp.tempSelectBitmap.get(i);//获取选择的图片
Bimp.tempSelectBitmap.clear();//清除选择的图片 （上传成功后记得调用此方法清除缓存的图片）
应用常用的城市列表选择功能，包括城市自动定位、热门城市、列表、精确搜索和自定义字母栏搜索。
// 初始化
private CityListAdapter mCityAdapter;//包括城市自动定位、热门城市、列表
private ResultListAdapter mResultAdapter;//精确搜索
setContentView(R.layout.cp_activity_city_list);
DBManager dbManager = new DBManager(this);
dbManager.copyDBFile();
List<City> mAllCities = dbManager.getAllCities();
private void initView() {
dbManager = new DBManager(this);
dbManager.copyDBFile();
mAllCities = dbManager.getAllCities();
mCityAdapter = new CityListAdapter(this, mAllCities);
mCityAdapter.setOnCityClickListener(new CityListAdapter.OnCityClickListener() {
@Override
public void onCityClick(String name) {
// back(name);
}
@Override
public void onLocateClick() {
// mCityAdapter.updateLocateState(LocateState.LOCATING, null);
mCityAdapter.updateLocateState(LocateState.SUCCESS, "重庆市");
}
});
mCityAdapter.updateLocateState(LocateState.SUCCESS, "重庆市");
mResultAdapter = new ResultListAdapter(this, null);
listviewAllCity.setAdapter(mCityAdapter);
sideLetterBar.setOverlay(textOverly);
listviewSearchResult.setAdapter(mResultAdapter);
sideLetterBar.setOnLetterChangedListener(new SideLetterBarView.OnLetterChangedListener() {
@Override
public void onLetterChanged(String letter) {
int position = mCityAdapter.getLetterPosition(letter);
listviewAllCity.setSelection(position);
}
});
listviewSearchResult.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// back(mResultAdapter.getItem(position).getName());
}
});
etSearch.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}
@Override
public void afterTextChanged(Editable s) {
String keyword = s.toString();
if (TextUtils.isEmpty(keyword)) {
ivSearchClear.setVisibility(View.GONE);
emptyView.setVisibility(View.GONE);
listviewSearchResult.setVisibility(View.GONE);
} else {
ivSearchClear.setVisibility(View.VISIBLE);
listviewSearchResult.setVisibility(View.VISIBLE);
List<City> result = dbManager.searchCity(keyword);
if (result == null || result.size() == 0) {
emptyView.setVisibility(View.VISIBLE);
} else {
emptyView.setVisibility(View.GONE);
mResultAdapter.changeData(result);
}
}
}
});
}
RecyclerView为Android在listview基础上优化的很强大的列表控件，在android应用开发中必不可少的控件，故此为了使用方便优化封装一下以便使用，可参考
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.skj.wheel.swiperecyclerview.MyRecyclerView
android:id="@+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_below="@+id/layout_view"

app:type="1" />
<com.skj.wheel.definedview.LayoutView
android:id="@+id/layout_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/text_color"

</RelativeLayout>
<!-- recyclerview的属性 -->
<declare-styleable name="MyRecyclerView">
<attr name="orientation" format="integer" />
<attr name="type" format="integer" />
</declare-styleable>
private ItemDecoration itemDecoration;//分割线
private int orientation = 1;//recyclerview 列表展现形式 垂直1或水平0
private int type = 0;//recyclerview 列表展现形式 列表1或网格0
MyRecyclerView 为集成 RecyclerView的封装的自定义view LayoutView为自定义的view主要是在列表显示时数据为空、错误、loading展示的界面（在下面会介绍）
app:orientation="0"列表展现形式 垂直1或水平0
app:type="1" 列表展现形式 列表1或网格0
removeDivider（） //移除分割线
/**
* 设置网格GridLayoutManager
*/
private GridLayoutManager gridLayoutManager;
public void setGridLayoutManager(Context context, int spaceCount) {
gridLayoutManager = new GridLayoutManager(context, spaceCount);
this.setLayoutManager(gridLayoutManager);
itemDecoration = new GridItemDecoration(DisplayUtil.dip2px(10));
this.addItemDecoration(itemDecoration);
}
/**
* 线性自定义分割线
*
* @param space 分割线的宽度
* @param mOrientation 垂直列表分割线0:top、3:bottom默认3;水平列表分割线1：left、2:right默认2
*/
public void setLinearItemDecoration(int space, int mOrientation) {
this.removeItemDecoration(itemDecoration);
itemDecoration = new LinearItemDecoration(space, mOrientation);
this.addItemDecoration(itemDecoration);
}
/**

*
* @param space 分割线的宽度
*/
public void setGridItemDecoration(int space) {
this.removeItemDecoration(itemDecoration);
itemDecoration = new GridItemDecoration(space);
this.addItemDecoration(itemDecoration);
}
有一种情况当列表为网格时且为不规则时配合 /** * 设置不规则网格 * * @param mList */ public void setGridlayoutSpaceCount(final List<?> mList) { gridLayoutManager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() { @Override public int getSpanSize(int position) { return setSpanSize(position, mList); } }); } 使用

MySwipeRLView为集成SwipeRefreshLayout的自定义控件，SwipeRefreshLayout为android自带的功能
MySwipeRLView配合 MyRecyclerView实现列表自带下拉刷新上拉加载更多
swipeRefresh.setOnSwipeListener(new MySwipeRLView.OnSwipeListener() {//下拉刷新
@Override
public void onRefresh() {
mList.clear();
for (int i = 0; i < 10; i++) {
mList.add("卧室的多多多" + i);
}
adapter.updateList(mList);
}
});
recyclerView.setOnBottomListener(new MyRecyclerView.OnBottomListener() {//上拉加载更多
@Override
public void onLoadMore() {
for (int i = 0; i < 10; i++) {
mList.add("卧室的多多多" + i);
}
adapter.updateList(mList);
}
});
}

</com.skj.wheel.swiperecyclerview.SwipeMenuLayout>
</LinearLayout>
SwipeMenuLayout为实现列表中一种滑动item时想弹出菜单时的功能
private int leftMenuId;//向右滑动显示左边菜单
private View leftMenuView;
private int rightMenuId;//向左滑动显示右边菜单
private View rightMenuView;
private int contentId;//中间自定义内容
private View contentView;
a、自定义密码框设置、获取、清空等操作 ``` <com.skj.wheel.definedview.GridPasswordView android:layout_width="match_parent" android:layout_height="@dimen/x50" android:layout_margin="@dimen/x20" />

android:id="@+id/layout_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/text_color"
android:visibility="gone" />
// layoutView.setVisibility(View.VISIBLE);
// layoutView.showEmpty(R.mipmap.ic_launcher_round, "空！");
// layoutView.showError(R.mipmap.ic_launcher_round, "错误！");
// layoutView.showLoading(R.mipmap.ic_launcher_round, "loading！");
c、 MyETView为自定义的输入框自带清除按键并对一些特殊字符进行限制
