android之图片选择器--pictureselector
推荐一个安卓图片/视频/文件选择器。简单好用。
不多废话。直接上代码：
首先，添加依赖：
//图片选择器
api 'io.github.lucksiege:pictureselector:v3.11.1'
//图片压缩
api 'io.github.lucksiege:compress:v3.11.1'
//图片裁剪
api 'io.github.lucksiege:ucrop:v3.11.1'
//自定义相机
api 'io.github.lucksiege:camerax:v3.11.1'
api 'com.github.bumptech.glide:glide:4.12.0'
这些依赖是必须的。其次是封装一下，方便后续使用
首先，创建 VideoThumbListener.java：
public class VideoThumbListener implements OnVideoThumbnailEventListener {
private Context context;
public VideoThumbListener(Context context) {
this.context = context;
}
@Override
public void onVideoThumbnail(Context context, String videoPath, OnKeyValueResultCallbackListener call) {
Glide.with(context).asBitmap().sizeMultiplier(0.6F).load(videoPath).into(new CustomTarget<Bitmap>() {
@Override
public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
resource.compress(Bitmap.CompressFormat.JPEG, 60, stream);
FileOutputStream fos = null;
String result = null;
try {
File targetFile = new File(getVideoThumbnailDir(), "thumbnails_" + System.currentTimeMillis() + ".jpg");
fos = new FileOutputStream(targetFile);
fos.write(stream.toByteArray());
fos.flush();
result = targetFile.getAbsolutePath();
} catch (IOException e) {
e.printStackTrace();
} finally {
PictureFileUtils.close(fos);
PictureFileUtils.close(stream);
}
if (call != null) {
call.onCallback(videoPath, result);
}
}
@Override
public void onLoadCleared(@Nullable Drawable placeholder) {
if (call != null) {
call.onCallback(videoPath, "");
}
}
});
}
private String getVideoThumbnailDir() {
File externalFilesDir = context.getExternalFilesDir("");
File customFile = new File(externalFilesDir.getAbsolutePath(), "Thumbnail");
if (!customFile.exists()) {
customFile.mkdirs();
}
return customFile.getAbsolutePath() + File.separator;
}
}
再次就是图片加载器的封装：GlideUtils：
public class GlideUtils implements ImageEngine {
/**
* 加载图片
*
* @param context 上下文
* @param url 资源url
* @param imageView 图片承载控件
*/
@Override
public void loadImage(Context context, String url, ImageView imageView) {
if (!ActivityCompatHelper.assertValidRequest(context)) {
return;
}
Glide.with(context)
.load(url)
// .error(R.mipmap.icon_photo_error)
.into(imageView);
}
/**
* 加载图片
*
* @param context 上下文
* @param url 资源url
* @param imageView 图片承载控件
* @param errorImage 图片加载失败资源文件
*/
public void loadImage(Context context, String url, ImageView imageView, int errorImage) {
if (!ActivityCompatHelper.assertValidRequest(context)) {
return;
}
Glide.with(context)
.load(url)
.error(errorImage)
.into(imageView);
}
@Override
public void loadImage(Context context, ImageView imageView, String url, int maxWidth, int maxHeight) {
if (!ActivityCompatHelper.assertValidRequest(context)) {
return;
}
Glide.with(context)
.load(url)
// .error(R.mipmap.ic_launcher)
.override(maxWidth, maxHeight)
.into(imageView);
}
/**
* 加载相册目录封面
*
* @param context 上下文
* @param url 图片路径
* @param imageView 承载图片ImageView
*/
@Override
public void loadAlbumCover(Context context, String url, ImageView imageView) {
if (!ActivityCompatHelper.assertValidRequest(context)) {
return;
}
Glide.with(context)
.asBitmap()
.load(url)
// .error(R.mipmap.ic_launcher)
.override(180, 180)
.sizeMultiplier(0.5f)
.transform(new CenterCrop(), new RoundedCorners(8))
// .placeholder(R.mipmap.ic_launcher)
.into(imageView);
}
/**
* 默认图片
*
* @param context
* @param url
* @param imageView
*/
public void loadVideoThumb(Context context, String url, ImageView imageView) {
loadVideoThumb(context, url, 0, imageView);
}
public void loadVideoThumb(Context context, String url, int errorImage, ImageView imageView) {
Glide.with(context)
.setDefaultRequestOptions(
new RequestOptions()
.frame(1000000)
.centerCrop()
.error(errorImage)
.placeholder(errorImage))
.load(url)
.into(imageView);
}
/**
* 获取视频第一证
* @param path 文件路径
* @return
*/
public Bitmap loadVideoThumb(String path) {
MediaMetadataRetriever media = new MediaMetadataRetriever();
media.setDataSource(path);
return media.getFrameAtTime();
}
/**
* 加载图片列表图片
*
* @param context 上下文
* @param url 图片路径
* @param imageView 承载图片ImageView
*/
@Override
public void loadGridImage(Context context, String url, ImageView imageView) {
if (!ActivityCompatHelper.assertValidRequest(context)) {
return;
}
Glide.with(context)
.load(url)
.override(200, 200)
.centerCrop()
// .error(R.mipmap.ic_launcher)
// .placeholder(R.mipmap.ic_launcher)
.into(imageView);
}
@Override
public void pauseRequests(Context context) {
Glide.with(context).pauseRequests();
}
@Override
public void resumeRequests(Context context) {
Glide.with(context).resumeRequests();
}
private GlideUtils() {
}
private static final class InstanceHolder {
static final GlideUtils instance = new GlideUtils();
}
public static GlideUtils createGlideEngine() {
return InstanceHolder.instance;
}
}

至于封装，到此就结束了。最后看一下用法，举例：：
打开相机：
PictureUtils.openCamera(this,false){
val localMedia = it[0]
}
选择X张照片：
PictureUtils.createImageMax(this, 9, arrayListOf<LocalMedia>()){
it.forEach { section ->
// section.realPath：获取图片路径
}
}
就简单列举两个。剩下的都差不多。
使用的时候别忘记添加权限哟。
