我的项目中的表情符号设置

Question

I referred https://github.com/vanniktech/Emoji

but iam getting one error.I did everything what he had said

final EmojiPopup emojiPopup = EmojiPopup.Builder.fromRootView(rootView).build(emojiEditText);   

(it is below " To open the EmojiPopup execute the code above: " line)

cannot resolve rootView

I'm unable to understand what is rootview here.

thanks a lot in advance

Answer 1

The rootView is the rootView of your layout xml file which will be used for calculating the height of the keyboard. emojiEditText is the EmojiEditText that you declared in your layout xml file.

This will be a View subclass that you instantiate through inflating an xml layout.

The layout he uses in the example is this one which is inflated as follows:

rootView = (ViewGroup) findViewById(R.id.main_activity_root_view);

Extracted from his own code samples . This would be the rootView in your above example.

Answer 2

I had the same problem...

First install the emoji installer in your splash activity or application class - basically it has to be executed before your layout is inflated in onCreate in your activity. Otherwise the layout will not recognize this <com.vanniktech.emoji.EmojiEditText /> .

// Init Emoji
EmojiManager.install(new IosEmojiProvider());

You also need a rootview as explained above by jugutier.
In your xml file declare the view widget like this (this is for constraint layout)

<View
   android:id="@+id/a_chat_v_keyboard"
   android:layout_width="match_parent"
   android:layout_height="200dp"
   app:layout_constraintBottom_toTopOf="@+id/view3"
   app:layout_constraintEnd_toEndOf="parent"
   app:layout_constraintHorizontal_bias="0.5"
   app:layout_constraintStart_toStartOf="parent" />

You can use the following in your activity class.

Declaration

private View vKeyboard;

Binding

vKeyboard = findViewById(R.id.a_chat_v_keyboard);

Then in your activity you can get the keyboard to pop up like this

final EmojiPopup emojiPopup = EmojiPopup.Builder.fromRootView(vKeyboard)
                                                .build(etTextMessage);

ivEmoticonToggle.setTag(1);

ivEmoticonToggle.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {

        emojiPopup.toggle();

        if (ivEmoticonToggle.getTag().equals(1)) {

            ivEmoticonToggle.setImageResource(R.drawable.keyboard);
            ivEmoticonToggle.setTag(2);

        } else {

            ivEmoticonToggle.setImageResource(R.drawable.emoticon);
            ivEmoticonToggle.setTag(1);

        }

    }
});

Answer 3

If you are using EmojiEditText in any Activity other than FirstActivity then install Emoji in the first activity using

EmojiManager.install(new IosEmojiProvider());

or if you are using this in the FirstActivity then Create a new class extended by the Application class and put this line in the onCreate method

EmojiManager.install(new IosEmojiProvider());

and put this line inside the application tag in your manifest file

android:name=".YourClassName"
