找不出来是为啥

下拉列表选中如何监听？setOnItemSelectedListener没有作用

categorySpinner.setEnabled(false);
billSpinner.setEnabled(false);

still, it is clickable. Please check.
Thanks.

Hi
This Library has multi select for spinner?

Thank You

I am getting following error while trying to sync my gradle file after adding following line to my gradle file

compile ('com.weiwangcn.betterspinner:library-material:1.1.0') {
exclude group: 'com.android.support', module: 'appcompat-v7'
exclude group: 'com.rengwuxian.materialedittext', module: 'library'
}

Error:

C:\android\MyProjectsAndStud\Twigly\app\build.gradle
Error:(48, 14) Failed to resolve: com.weiwangcn.betterspinner:library-material:1.1.0
Show in File
Show in Project Structure dialog

I have followed all your instructions, even make focusable to false in xml to prevent from getting exception, but when I touch spinner I am not getting anything, except getting above message in logcat.

How can I change the width of list item box or is there any way I can convert it into dialog box as in default spinner? Also is there any way I can customize the dark theme of list box into light one?

I try to set selected item index but with existing method "setSelection" nothing happened.

hi i use better spinner with custom adapter all works fine for me

 List<Employe> src= DBAdapter.getAllEmploye();
        Employe[] values = src.toArray(new Employe[src.size()]);
        adapter_emp = new SpinnerAdapter_emp(this, android.R.layout.simple_spinner_item,values);
        BetterSpinner textView = (BetterSpinner)
                findViewById(R.id.txtresps);
        BetterSpinner textView1 = (BetterSpinner)
                findViewById(R.id.txtrespr);
        textView.setAdapter(adapter_emp);

but when i select an item from the spinner .The spinner display me com.example.....model.employe
which is the name of my class displayed in the spinner

what's wrong please?

I want the spinner to disabled until a certain action is fulfilled
setEnabled(false) does not work

I added a listener to setOnItemSelectedListener, but those methods never get called:

    PaddedStringArrayAdapter deptAdapter = new PaddedStringArrayAdapter(getActivity(),
            android.R.layout.simple_spinner_item, getDepartmentNames());
    deptAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    MaterialBetterSpinner deptSpinner = (MaterialBetterSpinner) view.findViewById(R.id.deptSpinner);
    deptSpinner.setAdapter(deptAdapter);
    deptSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
            Toast.makeText(parent.getContext(), "onItemSelected", Toast.LENGTH_SHORT).show();
            Log.d("Console", "item selected");
        }

        @Override
        public void onNothingSelected(AdapterView<?> parent) {
            Log.d("Console", "nothing selected");
        }
    });

I also tried the setOnItemClickListener, but then the spinner takes a double tap to open, which is definitely not desirable.

    deptSpinner.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            //Toast.makeText(parent.getContext(), "onItemSelected", Toast.LENGTH_SHORT).show();
            Log.d("Console", "item selected");
        }
    });

Thank you and I look forward to your reply.

there is no method to capture the text selection

Please answer me for this as i imported the project rather than copy paste it. So it's hard to analyze a piece of code.

What about adding a dropdown indicator like the default spinner?

Please implement OnSelectedItem if you want it is better than default Spinner.

I want to set something like "CHOICE_MODE_MULTIPLE".
thank you very much for your effort and for this great library.

Is there a way to wrap content of drop down menu with a width larger than the size of spinner?

when spinner loses focus then requires 2 taps to open list.
I found some similar closed issues but no solution.

thank you!

How can I add a border to the spinner? stroke 1dp.

Hey!

I have the following issue like explained here:
#11

You said something about modify the java file and add it to your project. I don't know if did it correctly, but I think not because I get a java.lang.ClassCastException. I added the "MaterialBetterSpinner.java" to my project. Then I used in my Activity "import de.myprojects.utils.MaterialBetterSpinner".

This is how I actually added your library to my project (using Android Studio):

compile ('com.weiwangcn.betterspinner:library-material:1.1.0') {
    exclude group: 'com.android.support', module: 'appcompat-v7'
    exclude group: 'com.android.support', module: 'appcompat-v7'
}

Would be appreciate it, when you can explain me how I can add the files to my project, that I'm able to modify them.

Thanks!

I have iserted in my grandle this
compile ('com.weiwangcn.betterspinner:library-material:1.1.0') {
exclude group: 'com.android.support', module: 'appcompat-v7'
exclude group: 'com.rengwuxian.materialedittext', module: 'library'
}

and
in my layout this:

...
...
...
<com.weiwangcn.betterspinner.library.material.MaterialBetterSpinner
android:id="@+id/spinner2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="MaterialBetterSpinner"
app:met_floatingLabel="normal" />

but the compiler report me:

Error:(43) No resource identifier found for attribute 'met_floatingLabel' in package 'com.bandweb.myviewrecipes'

why?

Hi how do you change the right drawable?
setCompoundDrawablesWithIntrinsicBounds(0,0,R.drawable.my_drawable,0) doesn't seem to work.

Thanks

Hi Lesilva,

First of all thanks for the awesome library...It will be great if design support library is used for edittext instead of rengwuxian.materialedittext because it indirectly imports rengwuxian.materialedittext library even though design support library is used...

I'm trying to customize the view, but my default theme doesn't apply

<com.weiwangcn.betterspinner.library.material.MaterialBetterSpinner
android:id="@+id/item_type"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/item_type_hint"
app:met_floatingLabel="normal"
android:layout_marginTop="16dp"
android:layout_marginLeft="4dp"
android:layout_marginRight="4dp"
android:layout_marginBottom="4dp" />

None of margins or textColors or other customizations are working.

How can I do that?

Ty,

Hi, thanks for the library. Its great, I just had one query.

When you first click on the spinner it shows the items, but if the user clicks on back button to hide it without selecting to view the options later. Then the user will have to tap once and then twice for the items to show up again.

It also happens at times when you have selected an item already and want to change it, then the spinner will have to be clicked on twice to show up the items.

I want to change the color the divider... how to do ??

dear Lesilva ,
the framwork is easy to use ,and it looks beautiful ....
but if it did not setAdapter ,the app crash..
someTimes we need to get data from the website ,
so ... will you update it ??

Hello,

The following problem is really annoying.
While opening de xml to edit the layout files which contains
<com.weiwangcn.betterspinner.library.material.MaterialBetterSpinner

It gives to following rendering problems. After you close the rendering problems. Whenever you change something in xml it will again throws this rendering problem again. So basically it waste my time.
Are there any chance for you to add View.isineditmode in your code?

Btw, while running the application, I don't have any problem. It is just about the designing phase.

Rendering Problems The following classes could not be instantiated:
- com.weiwangcn.betterspinner.library.material.MaterialBetterSpinner (Open Class, Show Exception, Clear Cache)
Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE Exception Details java.lang.AssertionError   at android.content.res.BridgeResources.getDimensionPixelSize(BridgeResources.java:545)   at com.rengwuxian.materialedittext.MaterialAutoCompleteTextView.init(MaterialAutoCompleteTextView.java:330)   at com.rengwuxian.materialedittext.MaterialAutoCompleteTextView.(MaterialAutoCompleteTextView.java:316)   at com.weiwangcn.betterspinner.library.material.MaterialBetterSpinner.(MaterialBetterSpinner.java:30)   at java.lang.reflect.Constructor.newInstance(Constructor.java:422)   at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:704)   at android.view.LayoutInflater.rInflate_Original(LayoutInflater.java:835)   at android.view.LayoutInflater_Delegate.rInflate(LayoutInflater_Delegate.java:70)   at android.view.LayoutInflater.rInflate(LayoutInflater.java:811)   at android.view.LayoutInflater.rInflateChildren(LayoutInflater.java:798)   at android.view.LayoutInflater.rInflate_Original(LayoutInflater.java:838)   at android.view.LayoutInflater_Delegate.rInflate(LayoutInflater_Delegate.java:70)   at android.view.LayoutInflater.rInflate(LayoutInflater.java:811)   at android.view.LayoutInflater.rInflateChildren(LayoutInflater.java:798)   at android.view.LayoutInflater.rInflate_Original(LayoutInflater.java:838)   at android.view.LayoutInflater_Delegate.rInflate(LayoutInflater_Delegate.java:70)   at android.view.LayoutInflater.rInflate(LayoutInflater.java:811)   at android.view.LayoutInflater.rInflateChildren(LayoutInflater.java:798)   at android.view.LayoutInflater.inflate(LayoutInflater.java:515)   at android.view.LayoutInflater.inflate(LayoutInflater.java:394)

how to change spinner menu list item fonts?
I just changed spinner selected item text by:
app:ms_typeface="fonts/custom.ttf"

Found this today, will look into it later.

Thanks.

xml

                <BetterSpinner
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:layout_gravity="left"
                    android:layout_weight="1"
                    android:id="@+id/payment_methods"
                    android:text="Select Payment Methods" />

Java

  BetterSpinner spinner = (BetterSpinner) findViewById(R.id.payment_methods);

Gradle

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.1'
    compile 'com.android.support:design:23.1.1'
    compile 'com.wdullaer:materialdatetimepicker:2.2.0'
    compile ('com.weiwangcn.betterspinner:library-material:1.1.0') {
        exclude group: 'com.android.support', module: 'appcompat-v7'
        exclude group: 'com.rengwuxian.materialedittext', module: 'library'
    }
}

Even adding

import com.weiwangcn.betterspinner.library.BetterSpinner; 
import com.weiwangcn.betterspinner.library.material.MaterialBetterSpinner;

does not solve my problem.

It just gives out of bound index exception when I try using setSelected(index) method.

I have problems in "MaterialBetterSpinner" to touch the first time.

When the focus is on another component and then touched on Spinner, the popup does not open the first time, you need to touching two more times.

I believe the problem is the call of performFiltering(). https://github.com/Lesilva/BetterSpinner/blob/master/library-material/src/main/java/com/weiwangcn/betterspinner/library/material/MaterialBetterSpinner.java#L49

What is the reason for this call?

If spinner has requested focus and now you touch screen but not else view, onFocusChanged() will doesn't work, and the variable isPopup is still true. Now you need to double click to make spinner showDropDown().

How can i reset Spinner to default ?
How can i set Default item selected programmatically after initializing adapter?
spinner.setSelection(0); doesn't work

hi all,
i have to set floating label center

I love this plugin just cant seem to find a way to change the down arrow color.

I need to set an item selected, but how doesn't exist setSelection I tried to use setText, but when I did this, the other options in spinner disappears, somebody knows what's going on?

嗨，我用了这个jar，但是，在spinner一上来的时候，我是没有数据的，然后动态加载，怎么实现，我这边一致都只有一个item！求解

Please update MaterialEditText to latest, and is anyway to use setSelection like Spinner ?
I try to use setSelection, but show error...
java.lang.IndexOutOfBoundsException: setSpan (1 ... 1) ends beyond length 0

How do i get the position of the selected item in spinner..?
