Android图片选择器功能
【Android图片选择器功能】图片选择功能用的是GitHub上的依赖库,网址:https://github.com/guoxiaoxing/phoenix
先来看下我运行的效果图如下所示:

该依赖库是Android平台上拍照/录像,图片/视频选择,编辑和压缩的一站式解决方案。
添加依赖,在app->build.gradle里面添加依赖
//图片/视频选择、预览、编辑与拍照
implementation 'com.github.guoxiaoxing:phoenix:1.0.15'
初始化:
public class App extends Application {@Override
public void onCreate() {
super.onCreate();
Phoenix.config()
.imageLoader(new ImageLoader() {
@Override
public void loadImage(Context mContext, ImageView imageView
, String imagePath, int type) {
Glide.with(mContext)
.load(imagePath)
.into(imageView);
}
});
}
}
开启功能:
private void callUpSelecter(boolean isCamera, int type, int REQUEST_CODE) {if (TextUtils.isEmpty(fileID)) {
Phoenix.with()
.theme(PhoenixOption.THEME_RED)// 主题
.fileType(MimeType.ofImage())//显示的文件类型图片、视频、图片和视频
.maxPickNumber(9)// 最大选择数量
.minPickNumber(0)// 最小选择数量
.spanCount(4)// 每行显示个数
.enablePreview(true)// 是否开启预览
.enableCamera(isCamera)// 是否开启拍照
.enableAnimation(false)// 选择界面图片点击效果
.enableCompress(true)// 是否开启压缩
.compressPictureFilterSize(300)//多少kb以下的图片不压缩
.compressVideoFilterSize(2018)//多少kb以下的视频不压缩
.thumbnailHeight(160)// 选择界面图片高度
.thumbnailWidth(160)// 选择界面图片宽度
.enableClickSound(false)// 是否开启点击声音
.pickedMediaList(add_lists)// 已选图片数据
.videoFilterTime(0)//显示多少秒以内的视频
.mediaFilterSize(0)//显示多少kb以下的图片/视频,默认为0,表示不限制
.start(UploadMorePicActivity.this, type, REQUEST_CODE);
}}
获取结果:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 889 && resultCode == RESULT_OK) {//相册
//返回的数据
List result = Phoenix.result(data);
Log.e("=====result==", result.toString());
add_lists.clear();
add_lists.addAll(result);
adapter.updateItems(add_lists);
btnOkEnable(add_lists);
} else if (requestCode == 899 && resultCode == RESULT_OK) {//拍照
List result = Phoenix.result(data);
add_lists.addAll(result);
adapter.updateItems(add_lists);
btnOkEnable(add_lists);
}
}
recyclerView的适配基类:
/**
* recyclerView适配器基类
*/
public abstract class BaseRecyclerAdapter extends RecyclerView.Adapter {
public OnRecyclerViewItemClickListener mOnItemClickListener = null;
public OnRecyclerViewItemClickListenerData listenerData;
/**
* 数据集合
*/
protected List mItems;
protected Context mContext;
/**
* 构造函数
*/
public BaseRecyclerAdapter(Context context) {
this.mContext = context;
mItems = new ArrayList<>();
}/**
* 返回数据集
*/
public List getList() {
return mItems;
}/**
* 添加单条数据
*/
public void addItem(T item) {
if (item == null) return;
mItems.add(mItems.size(), item);
notifyItemInserted(mItems.size());
}/**
* 追加数据集合
*/
public void addItems(List items) {
if (items == null) return;
this.mItems.addAll(items);
notifyDataSetChanged();
}public boolean containsAll(List items) {
return mItems.containsAll(items);
}/**
* 更新指定行数据
*/
public void updateItem(T tasks, int position) {
if (tasks == null) return;
mItems.set(position, tasks);
notifyItemChanged(position);
}/**
* 更新全部数据
*/
public void updateItems(List items) {
if (items == null) return;
this.mItems.clear();
this.mItems.addAll(items);
notifyDataSetChanged();
}/**
* 移除指定行数据
*/
public void removeItem(int index) {
mItems.remove(index);
notifyItemRemoved(index);
notifyItemRangeChanged((index - 1) >= 0 ? index - 1 : 0, mItems.size());
}public void getView(int position, RecyclerView.ViewHolder viewHolder, int type, T item) {
}/**
* 返回指定行数据
*/
public T getItem(int location) {
if (mItems == null || mItems.isEmpty()) {
return null;
} else {
return mItems.get(location);
}
}/**
* 返回数据集合总数
*/
@Override
public int getItemCount() {
return mItems == null ? 0 : mItems.size();
}/**
* 清除全部数据
*/
public void clear() {
mItems.clear();
notifyDataSetChanged();
}public static interface OnRecyclerViewItemClickListener {
void onItemClick(View view, String data);
}public void setOnItemClickListener(OnRecyclerViewItemClickListener listener) {
this.mOnItemClickListener = listener;

R.layout.item_upload_more_pic_refresh
Activity中的代码:
public class UploadMorePicActivity extends AppCompatActivity

});
}
private void callUpSelecter(boolean isCamera, int type, int REQUEST_CODE) {if (TextUtils.isEmpty(fileID)) {

自定义ImageView:
public class CustomHeightImageView extends android.support.v7.widget.AppCompatImageView {
float scale = 0;
public CustomHeightImageView(Context context) {
super(context);
}public CustomHeightImageView(Context context, float scale) {
super(context);
this.scale = scale;
}public CustomHeightImageView(Context context, AttributeSet attrs) {
super(context, attrs);
TypedArray a = getContext().obtainStyledAttributes(attrs, R.styleable.CustomHeightRelativeLayout);
scale = a.getFloat(R.styleable.CustomHeightRelativeLayout_scale, -1f);
//float scale = a.
}@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
if (scale == -1) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
} else {
super.onMeasure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(
(int) (MeasureSpec.getSize(widthMeasureSpec) * (scale)),
MeasureSpec.getMode(widthMeasureSpec)));
}}
}
