本文介绍如何使用Android系统的内容解析器(ContentResolver)查询并筛选出JPEG和PNG格式的图片，并获取它们的存储路径。通过设置合适的查询条件，可以有效地定位到所需图片资源。
Uri mImageUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
//Uri mImageUri = MediaStore.Images.Media.INTERNAL_CONTENT_URI;
ContentResolver mContentResolver = MainActivity.this.getContentResolver();
//只查询jpeg和png的图片
Cursor mCursor = mContentResolver.query(mImageUri, null, MediaStore.Images.Media.MIME_TYPE + "=? or "
+ MediaStore.Images.Media.MIME_TYPE + "=?", new String[] { "image/jpeg", "image/png" },
MediaStore.Images.Media.DATE_MODIFIED);
while (mCursor.moveToNext()) {
//获取图片的路径
String path = mCursor.getString(mCursor.getColumnIndex(MediaStore.Images.Media.DATA));
//Uri mImageUri = MediaStore.Images.Media.INTERNAL_CONTENT_URI;
ContentResolver mContentResolver = MainActivity.this.getContentResolver();
//只查询jpeg和png的图片
Cursor mCursor = mContentResolver.query(mImageUri, null, MediaStore.Images.Media.MIME_TYPE + "=? or "
+ MediaStore.Images.Media.MIME_TYPE + "=?", new String[] { "image/jpeg", "image/png" },
MediaStore.Images.Media.DATE_MODIFIED);
while (mCursor.moveToNext()) {
//获取图片的路径
String path = mCursor.getString(mCursor.getColumnIndex(MediaStore.Images.Media.DATA));
}
