自定义股票键盘

在开发股票App的时候可能会被要求使用股票键盘，前一阵从不炒股得人第一次听说了股票键盘，后来查阅了一下，其实就是自定义的键盘，奈何一只搜索股票键盘，难住了我，所以我写了一个股票键盘。

话不多说直接上马了：

首先要先写一个布局（就是在要显示键盘的类的布局里）：

其中 KeyboardView键盘的控件。

接下来写一个键盘类：

import android.app.Activity;
import android.content.Context;
import android.inputmethodservice.Keyboard;
import android.inputmethodservice.KeyboardView;
import android.text.Editable;
import android.view.View;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.RelativeLayout;

import java.util.List;

import cn.uniwa.uniwa.R;

public class KeyBoardNumber {
    private KeyboardView keyboardView;
    private Keyboard k1;// 英文键盘
    private Keyboard k2;// 数字键盘
    private EditText ed;
    boolean b = true;
    Activity a;//接收传过来Activity
    LinearLayout ll;
    ImageView hotIvDel;
    LinearLayout hotLlResult;
    RelativeLayout hotRlNoFind;

    public KeyBoardNumber(Activity act, Context ctx, EditText edit) {//Activity可以将使用到此键盘的类传过来，也可以删除不传
        this.ed = edit;
        a = act;
        k1 = new Keyboard(ctx, R.xml.letter);
        k2 = new Keyboard(ctx, R.xml.symbols);
        keyboardView = (KeyboardView) act.findViewById(R.id.hot_keyboard_view);
        keyboardView.setKeyboard(k2);
        //软键盘是否启用
        keyboardView.setEnabled(true);
        //按键提示是否启用
        keyboardView.setPreviewEnabled(false);

        keyboardView.setOnKeyboardActionListener(listener);
        List keylist = k1.getKeys();

        for (Keyboard.Key key : keylist) {
            if (key.label != null && isword(key.label.toString())) {
                key.label = key.label.toString().toUpperCase();
                key.codes[0] = key.codes[0] - 32;
            }
        }
    }

    private KeyboardView.OnKeyboardActionListener listener = new KeyboardView.OnKeyboardActionListener() {
        @Override
        public void swipeUp() {
        }

        @Override
        public void swipeRight() {
        }

        @Override
        public void swipeLeft() {
        }

        @Override
        public void swipeDown() {
        }

        @Override
        public void onText(CharSequence text) {
        }

        @Override
        public void onRelease(int primaryCode) {
        }

        @Override
        public void onPress(int primaryCode) {
        }

        @Override
        public void onKey(int primaryCode, int[] keyCodes) {//注意！设置的键盘按钮可以再此方法内设置
            ll = (LinearLayout) a.findViewById(R.id.hot_ll_text);
            Editable editable = ed.getText();
            int start = ed.getSelectionStart();
            if (primaryCode == Keyboard.KEYCODE_CANCEL) {// 完成
//                Toast.makeText(KeyBoardNumber.this,"ok+"+editable,Toast.LENGTH_LONG).show();
//                hideKeyboard();
            } else if (primaryCode == Keyboard.KEYCODE_DELETE) {// 回退
                if (editable != null && editable.length() > 0) {
                    if (start > 0) {
                        editable.delete(start - 1, start);
//                        hotIvDel.setVisibility(View.GONE);
//                        hotLlResult.setVisibility(View.GONE);
//                        ll.setVisibility(View.VISIBLE);
//                        hotRlNoFind.setVisibility(View.GONE);
                    }
                }
            } else if (primaryCode == -15) {
                EditText ed = (EditText) a.findViewById(R.id.hot_et_search);//这些方法用不到可以删除，这是从使用键盘的activity传来的id
                hotLlResult = (LinearLayout) a.findViewById(R.id.hot_ll_result);
                hotRlNoFind = (RelativeLayout) a.findViewById(R.id.hot_rl_noFind);
                String text = ed.getText().toString();
               if (text.equals("")||text == null){
                   hotIvDel.setVisibility(View.GONE);
                   hotLlResult.setVisibility(View.GONE);
                   ll.setVisibility(View.VISIBLE);
                   hotRlNoFind.setVisibility(View.GONE);
               }
                hideKeyboard();
//                ll.setVisibility(View.VISIBLE);
//                ed.setText("");
            } else if (primaryCode == 4896) {// 清空
                editable.clear();
            } else if (primaryCode == 002) {
                editable.insert(start, "002");

            } else if (primaryCode == 300) {
                editable.insert(start, "300");

            } else if (primaryCode == 600) {
                editable.insert(start, "600");

            } else if (primaryCode == 601) {
                editable.insert(start, "601");

            } else if (primaryCode == 000) {
                editable.insert(start, "000");

            } else if (primaryCode == 115) {
                editable.insert(start, "S");
            } else if (primaryCode == 8016) {
//				editable.insert(start, "16");
                if (b) {
                    keyboardView.setKeyboard(k1);
                    b = false;
                } else {
                    keyboardView.setKeyboard(k2);
                    b = true;
                }

            } else {
                editable.insert(start, Character.toString((char) primaryCode));
            }
        }
    };

    public boolean isKeyBoardShow() {
        int visibility = keyboardView.getVisibility();
        if (visibility == View.GONE || visibility == View.INVISIBLE) {
            return false;
        } else {
            return true;
        }

    }

    public void showKeyboard() {
        int visibility = keyboardView.getVisibility();
        if (visibility == View.GONE || visibility == View.INVISIBLE) {
            keyboardView.setVisibility(View.VISIBLE);
        }
    }

    //隐藏键盘
    public void hideKeyboard() {
        int visibility = keyboardView.getVisibility();
        if (visibility == View.VISIBLE) {
            keyboardView.setVisibility(View.INVISIBLE);
        }
    }

    private boolean isword(String str) {
        String wordstr = "abcdefghijklmnopqrstuvwxyz";
        if (wordstr.indexOf(str.toLowerCase()) > -1) {
            return true;
        }
        return false;
    }

注意看我写的注释应该就能明白了

接下来是英文键盘：

数字键盘：

两个键盘内的功能键的codes都是重复的，可以进行数字英文进行切换

以上键盘设置完毕，只要在Activity中使用即可：

private KeyBoardNumber keyBoard;

keyBoard = new KeyBoardNumber(act, mContext, hotEtSearch);

 hotEtSearch.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                int inputback = hotEtSearch.getInputType();
//                hotEtSearch.setInputType(InputType.TYPE_NULL);
                keyBoard.showKeyboard();
                hotEtSearch.setInputType(inputback);
                return false;
            }
        });

这样就会显示键盘了；

但还是要注意，键盘布局的显示和隐藏；

如果有问题可以私聊我，会尽力帮忙。。
