Usage

Using ChatInputView only need two steps.

Step one: add ChatInputView in xml layout

    <cn.jiguang.imui.chatinput.ChatInputView
        android:id="@+id/chat_input"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        app:cameraBtnIcon="@drawable/aurora_menuitem_camera"
        app:inputCursorDrawable="@drawable/aurora_edittext_cursor_bg"
        app:inputEditTextBg="@drawable/aurora_edittext_bg"
        app:inputHint="@string/chat_input_hint"
        app:photoBtnIcon="@drawable/aurora_menuitem_photo"
        app:sendBtnIcon="@drawable/aurora_menuitem_send"
        app:voiceBtnIcon="@drawable/aurora_menuitem_mic" />

Step two: init ChatInputView

ChatInputView chatInputView = (ChatInputView) findViewById(R.id.chat_input);
chatInputView.setMenuContainerHeight(softInputHeight);

Attention please, MUST set MenuContainer's height after init ChatInputView. Best suggestion: get soft keyboard height from other activity(Like login Activity), then set soft keyboard height via:

ChatInputView chatinput = (ChatInputView) findViewById(R.id.chat_input);
chatinput.setMenuContainerHeight(softKeyboardHeight);

As for how to get soft keyboard height, you can listen onSizeChanged method. Please refer onSizeChanged in sample's MessageListActivity, and onSizedChanged in sample's ChatView.

Import interface and event

ChatInputView offers all kinds of click listener of button and event's callback, so that user can use event listener to do their stuff flexibly. Such as send message event etc.

OnMenuClickListener

First of all, OnMenuClickListener handling click event of menu item. Call chatInputView.setMenuClickListener can set this listener:

chatInput.setMenuClickListener(new OnMenuClickListener() {
    @Override
    public boolean onSendTextMessage(CharSequence input) {
         // After input content and click send button will fire this callback
    }

    @Override
    public void onSendFiles(List<String> list) {
        // chose photo or video files or finished recording video,
        // then click send button fires this event.
    }

    @Override
    public void switchToMicrophoneMode() {
        // click mic button in menu item, fires before showing record voice widget
    }

    @Override
    public void switchToGalleryMode() {
        // click photo button in menu item, fires before showing select photo widget
    }

    @Override
    public void switchToCameraMode() {
        // click camera button in menu item, fires before showing camera widget
    }
});

As for how to handle these events and what to do with these events, you can refer sample project for detail.

OnClickEditTextListener

Callback of click EditText，fires when click EidtText, usage：

mChatInput.setOnClickEditTextListener(new OnClickEditTextListener() {
            @Override
            public void onTouchEditText() {
                mAdapter.getLayoutManager().scrollToPosition(0);
            }
        });

RecordVoiceListener

This is the interface of record voice, the way to use:

mRecordVoiceBtn = mChatInput.getRecordVoiceButton();
mRecordVoiceBtn.setRecordVoiceListener(new RecordVoiceListener() {
    @Override
    public void onStartRecord() {
        // Show record voice interface
        // set directory to save audio files
        File rootDir = mContext.getFilesDir();
        String fileDir = rootDir.getAbsolutePath() + "/voice";
        mRecordVoiceBtn.setRecordVoiceFile(fileDir, new DateFormat().format("yyyy_MMdd_hhmmss",
                Calendar.getInstance(Locale.CHINA)) + "");
    }

    @Override
    public void onFinishRecord(File voiceFile, int duration) {
        MyMessage message = new MyMessage(null, IMessage.MessageType.SEND_VOICE);
        message.setMediaFilePath(voiceFile.getPath());
        message.setDuration(duration);
        message.setTimeString(new SimpleDateFormat("HH:mm", Locale.getDefault()).format(new Date()));
        mAdapter.addToStart(message, true);
    }

    @Override
    public void onCancelRecord() {

    }
});

OnCameraCallbackListener

This is interface related to camera, usage like：

mChatInput.setOnCameraCallbackListener(new OnCameraCallbackListener() {
    @Override
    public void onTakePictureCompleted(String photoPath) {
        MyMessage message = new MyMessage(null, IMessage.MessageType.SEND_IMAGE);
        message.setTimeString(new SimpleDateFormat("HH:mm", Locale.getDefault()).format(new Date()));
        message.setMediaFilePath(photoPath);
        message.setUserInfo(new DefaultUser("1", "Ironman", "ironman"));
        MessageListActivity.this.runOnUiThread(new Runnable() {
            @Override
            public void run() {
                mAdapter.addToStart(message, true);
            }
        });
    }

    @Override
    public void onStartVideoRecord() {

    }

    @Override
    public void onFinishVideoRecord(String videoPath) {
        // Fires when finished recording video.
        // Pay attention here, when you finished recording video and click send
        // button in screen, will fire onSendFiles() method.
    }

    @Override
    public void onCancelVideoRecord() {

    }
});

Set file path and file name that after taken picture

setCameraCaptureFile(String path, String fileName)

// The first parameter is file path that saved at, second one is file name
// Suggest calling this method when onCameraClick fires
mChatInput.setCameraCaptureFile(path, fileName);
