短视频带货源码，获取本地图片，并保存到bean
1.点击跳转到本地图片
case R.id.iv_wish_bg:
Intent intent = new Intent();
/* 开启Pictures画面Type设定为image */
intent.setType("image/*");
/* 使用Intent.ACTION_GET_CONTENT这个Action */
intent.setAction(Intent.ACTION_GET_CONTENT);
/* 取得相片后返回本画面 */
startActivityForResult(intent, 1);
break;
2.保存路径，并建立
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
if (resultCode == RESULT_OK) {
Uri uri = data.getData();
//这是本机的图片路径
img_url= UrlUtils.getPathByUri4kitkat(WishSettingActivity.this,uri);
etWishBg.setText("1");
ContentResolver cr = this.getContentResolver();//内容解析器
try {
Bitmap bitmap = BitmapFactory.decodeStream(cr.openInputStream(uri));//打开输出流
ImageView imageView = (ImageView) findViewById(R.id.iv_wish_bg);
/* 将Bitmap设定到ImageView */
imageView.setImageBitmap(bitmap);
} catch (FileNotFoundException e) {
Log.e("Exception", e.getMessage(),e);
}
}
super.onActivityResult(requestCode, resultCode, data);
}
3.getPathByUri4kitkat（）方法
@SuppressLint("NewApi")
public static String getPathByUri4kitkat(final Context context, final Uri uri) {
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
// DocumentProvider文件提供者
if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {
if (isExternalStorageDocument(uri)) {
// ExternalStorageProvider
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
if ("primary".equalsIgnoreCase(type)) {
return Environment.getExternalStorageDirectory() + "/" + split[1];
}
} else if (isDownloadsDocument(uri)) {
// DownloadsProvider
final String id = DocumentsContract.getDocumentId(uri);
final Uri contentUri = ContentUris.withAppendedId(Uri.parse("content://downloads/public_downloads"),
Long.valueOf(id));
return getDataColumn(context, contentUri, null, null);
} else if (isMediaDocument(uri)) {
// MediaProvider
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
Uri contentUri = null;
if ("image".equals(type)) {
contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
} else if ("video".equals(type)) {
contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
} else if ("audio".equals(type)) {
contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
}
final String selection = "_id=?";
final String[] selectionArgs = new String[] {
split[1] };
return getDataColumn(context, contentUri, selection, selectionArgs);
}
} else if ("content".equalsIgnoreCase(uri.getScheme())) {
// MediaStore
// (and
// general)
return getDataColumn(context, uri, null, null);
} else if ("file".equalsIgnoreCase(uri.getScheme())) {
// File
return uri.getPath();
}
return null;
}
/**

*/
public static String getDataColumn(Context context, Uri uri, String selection, String[] selectionArgs) {
Cursor cursor = null;
final String column = "_data";
final String[] projection = {
column };
try {

if (cursor != null && cursor.moveToFirst()) {
final int column_index = cursor.getColumnIndexOrThrow(column);
return cursor.getString(column_index);
}
} finally {
if (cursor != null)
cursor.close();
}
return null;
}
/**
* @param uri
* The Uri to check.
* @return Whether the Uri authority is ExternalStorageProvider.
*/
public static boolean isExternalStorageDocument(Uri uri) {
return "com.android.externalstorage.documents".equals(uri.getAuthority());
}
/**
* @param uri
* The Uri to check.
* @return Whether the Uri authority is DownloadsProvider.
*/
public static boolean isDownloadsDocument(Uri uri) {
return "com.android.providers.downloads.documents".equals(uri.getAuthority());
}
/**
* @param uri
* The Uri to check.
* @return Whether the Uri authority is MediaProvider.
*/
public static boolean isMediaDocument(Uri uri) {
return "com.android.providers.media.documents".equals(uri.getAuthority());
}
4.拿出来使用
if (img_url!=null){
Glide.with(WishShowActivity.this).load(img_url).into(ivBg);
}
