因为android10的出现 所以需要判断下版本号
方法1
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.Q) {
String[] proj = {MediaStore.Images.Media.DATA};
Cursor actualimagecursor = context.getContentResolver().query(uri, proj, null, null, null);
int actualImageColumnIndex = actualimagecursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
actualimagecursor.moveToFirst();
String imgPath = actualimagecursor.getString(actualImageColumnIndex);
context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(new File(imgPath))));
}
方法2
String[] filePathArray
String filePath;
String fileName;
String[] filePathColumn={MediaStore.MediaColumns.DATA,MediaStore.MediaColumns.DISPLAY_NAME};
ContentResolvercontentResolver=context.getContentResolver();
Cursorcursor=contentResolver.query(contentUri, filePathColumn,null,
null,null);
cursor.moveToFirst();
filePath=cursor.getString(cursor.getColumnIndex(filePathColumn[0]));
fileName=cursor.getString(cursor.getColumnIndex(filePathColumn[1]));
cursor.close();
filePathArray=newString[]{filePath,fileName};
MediaScannerConnection.scanFile(context,newString[] {filePathArray[0]},newString[]{"image/jpeg"},newMediaScannerConnection.OnScanCompletedListener(){
@Override
publicvoidonScanCompleted(Stringpath,Uriuri) {
Log.e(TAG,"PATH:"+path);
}
} );
这两种方法 都OK
