file explorer looks completely different than the pressed file

file explorer looks completely different than the pressed file - java

  how can I solve this problem.
In the file explorer, when I hit a video file. something else appears in alertdialog. It theoretically should occur, the file pressed.
How can I solve?
Thank you.
I added 2 photos to better understand the error.

How to handle loading large amounts of data in android

I have an activity with a button upon clicking which opens a new activity with 3 fragments with tab layout, The first fragment loads files from the internal storage in recyclerview, 2nd one loads installed apps in recyclerview and the 3rd loads contacts in a recyclerview, But the problem I'm facing is that when I click the button to launch the activity it takes 2-3 seconds to launch the activity & I tested it on a device which contained a lot of apps and contacts it crashed the app and didn't opened the activity, I think this is because it is taking time to load all the data at once, How can I solve this problem?
This is the code from the fragments

save state of my game in database

In my project I download all the data of my project from a json.I download title and description as text and also download my icon and the file of games.
I can download them and also save in database and show in listview easily.
My QUESTION is about how to save that my file for game is beinng download or not?
I have two buttons. first is download button when user click it , it starts to download file.when download finish, my download button disappear and my play button appears.
I want to save this, when user for second time run the application,i save for example my second position downloaded before. and I have just my play button.
my database:
public class DatabaseHandler extends SQLiteOpenHelper {
public SQLiteDatabase sqLiteDatabase;
int tedad;
public DatabaseHandler(Context context) {
super(context, "EmployeeDatabase.db", null, 1);
}
#Override
public void onCreate(SQLiteDatabase db) {
String tableEmp = "create table emp(PersianTitle text,Description text,icon text,downloadlink text,dl integer)";
db.execSQL(tableEmp);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
}
public void insertData(ArrayList<String> id, ArrayList<String> name, ArrayList<String> salary, ArrayList<String> roms,String
dl) {
int size = id.size();
tedad = size;
sqLiteDatabase = this.getWritableDatabase();
try {
for (int i = 0; i < size; i++) {
ContentValues values = new ContentValues();
values.put("PersianTitle", id.get(i));
values.put("Description", name.get(i));
values.put("icon", salary.get(i));
values.put("downloadlink", roms.get(i));
values.put("dl", "0");
sqLiteDatabase.insert("emp", null, values);
}
} catch (Exception e) {
Log.e("Problem", e + " ");
}
}
public ArrayList<String> Game_Info (int row, int field) {
String fetchdata = "select * from emp";

how to make method in my database to do this?

If I understood you properly, you can add a table, user_games for example with User ID, Game ID and Status, then you can update status whenever an action is completed.
For example Status 1 for downloading, status 2 for Downloaded or Finished and you can even add statuses like download failed, to add a re-download button...
you can do something like
public void update_status(UserID,GameID) {
String update = "UPDATE games set status = 1 where id="+Game_ID+" and UserID = " + UserID);
db.rawQuery(update, null);
}

How to get filepath from sdcard in android

When I clicked on button I want to get a filepath from a filename. I am using custom BaseAdapter for that I am passing ArrayList<String>. I am getting file name but also i need absolute filepath from sdcard. Here is my code in getView();
String mFileName = myitem.get(position);
viewHolder.bt_encrypt.setTag(mFileName);
In onclick of button I added below piece of code to get a file when i clicked on button of same row
String fileName = (String) v.getTag();
From this how to get filepath ?
full code
private void getDir(String dirPath){
item = new ArrayList<String>();
path = new ArrayList<String>();
File f = new File(dirPath);
File[] files = f.listFiles();
if(!dirPath.equals(MainActivity.root_sd_path)){
item.add(MainActivity.root_sd_path);
path.add(MainActivity.root_sd_path);
item.add("../");
path.add(f.getParent());
}
for(int i=0; i < files.length; i++)
{
File file = files[i];
if(!file.isHidden() && file.canRead()){
path.add(file.getAbsolutePath());
if(file.isDirectory()){
item.add(file.getName() + "/");
}else{
item.add(file.getName());
}
}
}
SDcardFiles sdcardFilesAdapter = new SDcardFiles(item, dirPath);
setListAdapter(sdcardFilesAdapter);
}

THANKS

you can try something like this
Environment.getExternalStorageDirectory().getAbsolutePath();

I am trying to to attach files which places on some folder in Sdcard. I am able to fetch files from gallery and other media type but no luck so far to browse sdcard so i could choose text files (Doc, docx, pdf etc). The requirement is very close to Email-attach menu option in Email-Application of Android device which allows user view Sdcard folders by Intent.
If anybody have such an experience to browse Sdcard and its Contents please share code or guide me. many Thanks in advance.

One way is that, pragmatically show required files and folders in your app and let user select the files to be attached.
As far as showing particular folder through intent is concerned, seems there is no built in app to do that.
Have a look at this link.

How to use onLongClick method in ListView?

Hello guys I'am totally new in android and I have an assignment that will output an option when a user long clicks the item that is in list view. Can you help me about this? thanks in advance.

Create a setOnItemLongClickListener
My Code:
ListView lv = (ListView) findViewById(R.id.listView1);
lv.setLongClickable(true);
lv.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView<?> arg0,View arg1,int arg2, long arg3){
ListView lv = (ListView) findViewById(R.id.listView1);
// Todo
}});

you havent initialize your listview with xml listview..
ListView lst=null;
put below line after that:
lst = (ListView) findViewById(R.id.xmllistviewid);
and put your setOnItemLongClickListener method outside the onlistitemclick method.

Try this ::
lv.setOnItemLongClickListener(new OnItemLongClickListener() {
public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
int pos, long id) {
// TODO Auto-generated method stub
Log.v("long clicked","pos"+" "+pos);
return true;
}
});
Refer this link.It is nicely explained about how to implement onItemClick() and onItemLongClick() in listview.

you can use like that
listview.setOnItemLongClickListener(new OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view,
int arg2, long arg3) {
// Can't manage to remove an item here
return false;
}
});
