Search filter on list view returns wrong result on clicking

Problem
I am creating music player using android studio.
Everything was fine until I added search filter to search songs.
Search filter returns the song right but when I click on searched result wrong music file is opened however the music name shown on player activity is right but the song played is first song of list every time .
Example
There are 4 song items named: A,B,C,D
When searched C ,filtered result C is shown. But when Clicked on it Song name C is shown but Song A is played.
This is really frustrating.

In above image, you see that you are sending the position of filtered array and sending the songs list (mysongs) which is not filtered. That's why it's happening.
So you need to do is that either send the filtered array. Or add some logic to get the correct position from songs list. that's it.
if you can not figure out then let me know I will update appropriate logic.

Why item on menu drawer can't click ? Android Navigation

I have a really interesting problem with my Navigator menu. I have no idea why... But I can click on any item from my menu, I don't want to say I click and nothing happened. I really want to say I can't click on any item, all my menu it's like a big image. I've try to make a new project witch already have Navigation Drawer Activity, of course it works.. but when I've try to copy that code and put on mine.. I have the same problem and vice versa, I've try to put my code into a new project with Navigation Drawer Activity, but again... I can't click on any item.
image - this trouble
image - can't click

i've tried, how can i fix it ? anyone please help me. thanks.

Anyone else having similar problem. It appears the order in the XML matters too.
I had my NavigationView and after it I had a layout included and I couldn't click an item on the NavigationView.
After I switched them, so that my layout was being included AND THEN AFTER IT I had my NavigationView, it worked ...

this adapter.java
public class Adapter extends BaseAdapter {
private Activity activity;
private LayoutInflater inflater;
private List<DataModel> item;
public Adapter(Activity activity, List<DataModel> item) {
this.activity = activity;
this.item = item;
}
#Override
public int getCount() {
return item.size();
}
#Override
public Object getItem(int location) {
return item.get(location);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (inflater == null)
inflater = (LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null)
convertView = inflater.inflate(R.layout.list_buddies, null);
TextView txt_nama = (TextView) convertView.findViewById(R.id.custom_list_item_text1);
txt_nama.setText(item.get(position).getNama());
return convertView;
}
}

You need to create this type of your layout xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" android:id="#+id/drawer_layout"
android:layout_width="match_parent" android:layout_height="match_parent"
android:fitsSystemWindows="true" tools:openDrawer="start">
<FrameLayout
android:id="#+id/container"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
</FrameLayout>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_menu_bar"
app:menu="#menu/activity_menu_bar_drawer" />
</android.support.v4.widget.DrawerLayout>
In FrameLayout you need to replace all fragment one by one like
private void callFragment(Fragment fragment) {
fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container, fragment)
.commit();
}
Note: You can write your Coordinator layout and other in fragment itself, may be helpful for you.

Viewpager in Dialog?

I'm trying to have a dialog where you can click a "next" button to swipe right to the next screen. I am doing that with a ViewPager and adapter:
final Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.voicedialog);
dialog.setCanceledOnTouchOutside(false);
MyPageAdapter adapter = new MyPageAdapter();
ViewPager pager = (ViewPager) findViewById(R.id.viewpager);
pager.setAdapter(adapter);
However, I get a NullPointerException saying that pager is null. Why is this happening? Here is the Page Adapter class:
public class MyPageAdapter extends PagerAdapter {
public Object instantiateItem(ViewGroup collection, int position) {
int resId = 0;
switch (position) {
case 0:
resId = R.id.voice1;
break;
case 1:
resId = R.id.voice2;
break;
}
return collection.findViewById(resId);
}
#Override
public int getCount() {
return 2;
}
#Override
public boolean isViewFromObject(View arg0, Object arg1) {
return arg0 == arg1;
}
}
Here's my layout for the DIALOG:
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
Let me know on how to avoid this situation.
PS: Each of the layouts that should be in the view pager look like this, just diff. text:
<RelativeLayout android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/voice2"
xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:text="Slide 1!"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/textView2"
android:layout_gravity="center"
android:textSize="50sp" />
</RelativeLayout>

Without Using Enum Class
You should call findViewById on dialog. so for that you have to add dialog before findViewById..
Like this,
ViewPager pager = (ViewPager) dialog.findViewById(R.id.viewpager);
After solving your null pointer exception the other problem's solution here, if you wont use enum class you can use below code...
MainActivity.java

btn= (Button) findViewById(R.id.btn);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
final Dialog dialog = new Dialog(MainActivity.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.voicedialog);
dialog.setCanceledOnTouchOutside(false);
MyPageAdapter adapter = new MyPageAdapter(MainActivity.this);
ViewPager pager = (ViewPager) dialog.findViewById(R.id.viewpager);
pager.setAdapter(adapter);
dialog.show();
}
});

Improve this question
Hello this is my first question so please forgive me if its in bad format, I have my main activity with three buttons,Button 1 and 2 lead to numberpickers that allow user to pick from numbers to set a background image. My problem is once they pick the color (rgb) i need it sent back to the main activity but then i want the button to immediately change to the background color they chose then they can go to button two and do the same thing, at the end of the process both button1 and 2 should be the colors they have chosen. Which i will then mix in button 3(which i havent at all started on) My main problem is i pick one then it set but then i pick the other one and it onCreates() and sets the other back to a default , So i somehow need to change the colors immedietly after the activity returns to the main activity my code is a bit ugly but ive just been trying to get it working then i was gonna go back and make it more efficient so my apologize

For this you have to call startActivityForResult every time when you open ColorPicker1/2/3
Like this
Intent i1 = new Intent(MainActivity.this,ColorPicker1.class);
startActivityForResult(i1,REQUEST_CODE_COlLOR1);
//REQUEST_CODE must be greater than`0` so keep it `101` for example
and for ColorPicker2 keep REQUEST_CODE_COlLOR2 as 102 and for ColorPicker3 REQUEST_CODE_COlLOR2 as 103
and in your ColorActivity1/2/3 Call intent like this with respective request codes
Intent i = new Intent();
i.putExtra("color1", yourColor);
setResult(REQUEST_CODE_COlLOR1, i);
finish();
for in Second color activity
Intent i = new Intent();
i.putExtra("color2", yourColor);
setResult(REQUEST_CODE_COlLOR2, i);
finish();
In your mixed
Intent i = new Intent();
i.putExtra("color3", yourColor);
setResult(REQUEST_CODE_COlLOR3, i);
finish();
and then write OnActivityResult Override method in MainActivity to get the result from ColorPicker1/2/3
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// Check which request we're responding to
if (requestCode == REQUEST_CODE_COlLOR1) {
// Make sure the request was successful
if (resultCode == RESULT_OK) {
//Set your color on your first button
yourColor = data.getExtras().get("color1");
}
}
if (requestCode == REQUEST_CODE_COlLOR2) {
// Make sure the request was successful
if (resultCode == RESULT_OK) {
//Set your color on your second button
yourColor2 = data.getExtras().get("color2");
}
}
if (requestCode == REQUEST_CODE_COlLOR3) {
// Make sure the request was successful
if (resultCode == RESULT_OK) {
//Set your color on your mixed color button
yourColor3 = data.getExtras().get("color3");
}
}
}

Creating an action bar on Android

Good evening, I'm still a noob with code and i wondered if someone could help:)
I want to put an action bar on an Activity that i've already made, where i also want to add the app icon but I already know how to do that, i just want to know how to put an action bar.
