flingContainer.setMaxVisible(4);

flingContainer.setAdapter(arrayAdapter);

}
flingContainer.setFlingListener(new SwipeFlingAdapterView.onFlingListener() {

}

});
// Optionally add an OnItemClickListener

But i want the images to come like a stack.. Not exactly overlapped. Refer this
Can anyone help me achieve this?

This is a link with your solution https://github.com/Diolor/Swipecards
Incase you use custom ArrayAdaper on inflating layout this is the code that worked for me
inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.swipe_item, parent, false);

Include this permission in manifest if you are storing pdf in external storage.
Use Asset folder like this
AssetManager assetManager = getAssets();
File file = new File(getFilesDir(), "xyz.pdf");
in = assetManager.open("xyz.pdf");
out = openFileOutput(file.getName(), Context.MODE_WORLD_READABLE);
copyFile(in, out);
in.close();
in = null;
out.flush();
out.close();
out = null;

You can open it as an input stream like this from a fragment
reader = new BufferedReader(new InputStreamReader(getActivity().getAssets().open(myfile.pdf))
You don't need permisssions as you're accessing your app's internal files but putting pdf into assets can increase the weight of the app , be careful
and then you can save it as string like that
private StringBuilder text = new StringBuilder();
String mLine;
while ((mLine = reader.readLine()) != null) {
text.append(mLine);
text.append('\n');
}
if (reader != null) {
try {
reader.close();
} catch (IOException e) {
//log the exception
}

Custom EditTextDialog is broken in Android 4.3

I'm currently working on an application and I have and unwanted behavior on my custom EditText Dialog. Here's the XML code
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<EditText
android:id="#+id/editText_dialog"
android:layout_width="fill_parent"
android:inputType="textCapSentences"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:textAppearance="?android:attr/textAppearanceMedium"/>
</android.support.design.widget.TextInputLayout>
<RelativeLayout
android:layout_marginTop="10dp"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/close_dialog"
android:id="#+id/cancel_dialog"
android:textSize="20sp"
android:layout_margin="20dp"
android:layout_gravity="right"
android:layout_toLeftOf="#+id/valid_dialog" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/validate_dialog"
android:id="#+id/valid_dialog"

android:layout_margin="20dp"
android:layout_gravity="right"
android:textColor="#android:color/holo_blue_light"
android:layout_alignParentRight="true" />
</RelativeLayout>S7
</LinearLayout>
And here is the class for the TextEditDialog
package com.fitme.staffbooker;
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.text.InputType;
import android.view.View;
import android.widget.EditText;
import android.widget.NumberPicker;
public class EditTextDialog extends Dialog {
private EditText editText;
public boolean dismissed = false;
public EditTextDialog(Context context, String title) {
super(context, android.R.style.Theme_Holo_Light_Dialog);
setTitle(title);
}
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.edit_text_dialog);
editText = (EditText) findViewById(R.id.editText_dialog);
findViewById(R.id.valid_dialog).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dismissed = true;
dismiss();
}
});
findViewById(R.id.cancel_dialog).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
cancel();
}
});
}
public void setHint(String str) {
editText.setHint(str);
}
public void setText(String str) {
editText.setText(str);
}
public void setInputType(int type) {
editText.setInputType(type);
}
public String getValue() {
return editText.getText().toString();
}
}
Here's the output i'm having on my Galaxy S7 Edge :
But when I'm running my app on a Galaxy SIII Emulator it seems broken :
It seems that this only happens on 4.3 and below. I have no idea what is happening.

PopUp Window not updating database - Android

I'm trying to create a kind of game using Android Studio. Till now I have done a gridview wich shows players stored in a database. I have had some problems with gridView.setOnItemClickListener, I have had to do it by putting the code into gridView's Adparter.class so if you know how I can do that into gridView's activity please tell me.
My problem now is that when you click on a player a popup window appears in which you could change the player's name or his genre. When you click on Confirm's button the database will automatically been updated, but it doesn't works. I have try to do it step by step by using Toast in order to know if it run that part or not, the problem could be the context, but maybe I'm crazy.
I left you some pics and the code related to it.

From what I´ve seen in your code is, that you try to get the id from an intent in your PopUp window class. You have made one thing wrong:
Intent i = getIntent();
i.getIntExtra("Id", id);
it must be:
Intent i = getIntent();
id = i.getIntExtra("Id", id); //forgott id = here
and you should give a default value to id for example id=-1 . The problem is, by updating your database, you give a non value integer and so it is not possible to update your table.

In your onCheckedChanged() method save the positions in a list. and when button is clicked iterate through the list and delete them from the adapter list.

Using getFragmentManager on a ListActivity

I just want to know if this is possible since first. I have created a custom listView based on the tutorial I read from Sai Geetha. Well it works perfectly on my app except that it needs to extend ListActivity instead of FragmentActivity. Now I'm having a hard time configuring and adding a dialog for this since I need to apply a fragment dialog and I can't use the getFragmentManager() since I'm not working with the FragmentActivity. Is there's another way I can do to work on this without sacrificing the ListActivity? Thanks!
Here's my code so far
