定义布局

            <TextView
                android:id="@+id/input_tv"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:gravity="center_vertical"
                android:textSize="18sp"
                android:background="@color/green_title_bar"/>

            <com.open.androidtvwidget.keyboard.SkbContainer
                android:id="@+id/skbContainer"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" >
            </com.open.androidtvwidget.keyboard.SkbContainer>

代码逻辑

@Bind(R.id.skbContainer)
SkbContainer skbContainer;

@Bind(R.id.input_tv)
TextView inputTv;

public void setKeyBoard() {
        skbContainer.setSkbLayout(R.xml.skb_all_key);
        skbContainer.setFocusable(true);
        skbContainer.setFocusableInTouchMode(true);


        // 设置属性(默认是不移动的选中边框)
        setSkbContainerMove();
        //
        skbContainer.setSelectSofkKeyFront(false); // 设置选中边框最前面.
        // 监听键盘事件.
        skbContainer.setOnSoftKeyBoardListener(new SoftKeyBoardListener() {
            @Override
            public void onCommitText(SoftKey softKey) {

                int keyCode = softKey.getKeyCode();
                String keyLabel = softKey.getKeyLabel();
                if (!TextUtils.isEmpty(keyLabel)) { // 输入文字.
                    inputTv.setText(inputTv.getText() + softKey.getKeyLabel());
                } else { // 自定义按键，这些都是你自己在XML中设置的keycode.
                    keyCode = softKey.getKeyCode();
                    if (keyCode == KeyEvent.KEYCODE_DEL) {
                        String text = inputTv.getText().toString();
                        if (TextUtils.isEmpty(text)) {
                            Toast.makeText(getApplicationContext(), "文本已空", Toast.LENGTH_LONG).show();
                        } else {
                            inputTv.setText(text.substring(0, text.length() - 1));
                        }
                    } else if (keyCode == KeyEvent.KEYCODE_BACK) {
                        finish();
                    } else if (keyCode == KeyEvent.KEYCODE_ENTER) {
                        keyboard.setVisibility(View.GONE);
                    }
                }

            }

            @Override
            public void onBack(SoftKey key) {
                finish();
            }

            @Override
            public void onDelete(SoftKey key) {
                String text = inputTv.getText().toString();
                inputTv.setText(text.substring(0, text.length() - 1));
            }

        });
        // DEMO（测试键盘失去焦点和获取焦点)
        skbContainer.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                OPENLOG.D("hasFocus:" + hasFocus);
                if (hasFocus) {
                    if (mOldSoftKey != null)
                        skbContainer.setKeySelected(mOldSoftKey);
                    else
                        skbContainer.setDefualtSelectKey(0, 0);
                } else {
                    mOldSoftKey = skbContainer.getSelectKey();
                    skbContainer.setKeySelected(null);
                }
            }
        });

    }

设置属性

private void setSkbContainerMove() {
        mOldSoftKey = null;
        skbContainer.setMoveSoftKey(true); // 设置是否移动按键边框.
        RectF rectf = new RectF((int) getResources().getDimension(R.dimen.
                w_2), (int) getResources().getDimension(R.dimen.
                h_2), (int) getResources().getDimension(R.dimen.
                w_2), (int) getResources().getDimension(R.dimen.
                h_2));
        skbContainer.setSoftKeySelectPadding(rectf); // 设置移动边框相差的间距.
        skbContainer.setMoveDuration(200); // 设置移动边框的时间(默认:300)
        skbContainer.setSelectSofkKeyFront(true); // 设置选中边框在最前面.
    }

监听键盘按下和松开的事件

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (skbContainer.onSoftKeyDown(keyCode, event))
            return true;

        if (keyCode == KeyEvent.KEYCODE_BACK) {
            finish();
            return true;

        }
        return super.onKeyDown(keyCode, event);
    }

    @Override
    public boolean onKeyUp(int keyCode, KeyEvent event) {
        if (skbContainer.onSoftKeyUp(keyCode, event))
            return true;
        return super.onKeyDown(keyCode, event);
    }

键盘的布局放在res/xml下
