[英]How to get an image from the gallery, get its name, save it in the internal memory and get the route of that image
(I apologize if I make mistakes writing in English) I need to do the same as the title says I only know how to get the image from the gallery. (如果我用英语写错了,我深表歉意)我需要做的事情与标题所说的一样,我只知道如何从图库中获取图像。 I think this is correct:
我认为这是正确的:
(If it is wrong or it is inefficient please let me know) (如果错误或效率低下,请告诉我)
private final int SELECT_PICTURE = 200;
btnAddImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent galeryIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
galeryIntent.setType("image/*");
startActivityForResult(galeryIntent.createChooser(galeryIntent, "Sececiona Imagen"), SELECT_PICTURE);
}
});
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode){
case (SELECT_PICTURE):
if(requestCode == RESULT_OK){
Uri path = data.getData();
}
}
break;
}
}
But I don't know how to get the name of the image that I caught from the gallery and save it whit that name in the internal memory of my app. 但是我不知道如何获取从图库中捕获的图像的名称,并将其保存在应用程序的内部存储器中。 Then I need the route of the image like "MyAPP/media/ ..." , I don't know the correct name in English for that, and save it in my database (save it in my database is easy) and then use it in my project
然后,我需要像“ MyAPP / media / ...”之类的图像的路径,我不知道英语的正确名称,然后将其保存在数据库中(将其保存在数据库中很容易),然后使用在我的项目中
I know this is a long message but I need your help because in the Spanish forum of StackOverflow anybody answered me. 我知道这是一条很长的信息,但是我需要您的帮助,因为在StackOverflow西班牙论坛中,有人回答了我。
onActivityResult : onActivityResult:
String path = getPath(getApplicationContext(), data.getData());
File mFile = new File(id);
mFile.getName();
That is the way that a got the name of the file. 这就是获取文件名的方法。
And the getPath : 和getPath:
public static String getPath(final Context context, final Uri uri) {
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {
if (isExternalStorageDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
Log.d("Lucas","TYPE => "+type);
if ("primary".equalsIgnoreCase(type)) {
return Environment.getExternalStorageDirectory() + "/" + split[1];
}
} else if (isDownloadsDocument(uri)) {
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)) {
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())) {
return getDataColumn(context, uri, null, null);
} else if ("file".equalsIgnoreCase(uri.getScheme())) {
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 {
cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs,
null);
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;
}
public static boolean isExternalStorageDocument(Uri uri) {
return "com.android.externalstorage.documents".equals(uri.getAuthority());
}
public static boolean isDownloadsDocument(Uri uri) {
return "com.android.providers.downloads.documents".equals(uri.getAuthority());
}
public static boolean isMediaDocument(Uri uri) {
return "com.android.providers.media.documents".equals(uri.getAuthority());
}
