自定义键盘实现

#1 效果图（多种键盘视图，请看完gif）

#2 步骤（只显示关键代码，具体实现在示例代码中）

1.屏蔽系统键盘

@Override

public void onCreate(Bundle savedInstanceState) {

...

if (android.os.Build.VERSION.SDK_INT <= 10) { //解决sdk4.0以上光标不显示问题

etzqdm.setInputType(InputType.TYPE_NULL);

} else {

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

try {

Class<EditText> cls = EditText.class;

Method setShowSoftInputOnFocus = cls.getMethod("setShowSoftInputOnFocus", boolean.class);

setShowSoftInputOnFocus.setAccessible(true);

setShowSoftInputOnFocus.invoke(etzqdm, false);

} catch (Exception e) {

e.printStackTrace();

}

}

...

}

2. 配置KeyBoard键盘

1）xml中声明

2）res中新建xml文件夹，配置键盘视图（相关xml属性见个人前一篇博客）

一个简单的数字键盘

<?xml version="1.0" encoding="utf-8"?>

<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"

android:horizontalGap="0dp"

android:keyHeight="10%p"

android:keyWidth="25%p"

android:verticalGap="0dp">

<Row>

<Key android:codes="49" android:keyLabel="1" android:keyEdgeFlags="left" />

<Key android:codes="50" android:keyLabel="2" />

<Key android:codes="51" android:keyLabel="3" />

<Key

android:codes="-5"

android:keyHeight="20%p"

android:keyEdgeFlags="right"

android:keyIcon="@drawable/keyboard_delete"

/>

</Row>

<Row>

<Key android:codes="52" android:keyLabel="4" android:keyEdgeFlags="left" />

<Key android:codes="53" android:keyLabel="5" />

<Key android:codes="54" android:keyLabel="6" />

</Row>

<Row>

<Key android:codes="55" android:keyLabel="7" android:keyEdgeFlags="left" />

<Key android:codes="56" android:keyLabel="8" />

<Key android:codes="57" android:keyLabel="9" />

<Key

android:codes="-4"

android:keyHeight="20%p"

android:keyEdgeFlags="right"

android:keyLabel="买入"

/>

</Row>

<Row>

<Key android:codes="46" android:keyLabel="." android:keyEdgeFlags="left" />

<Key android:codes="48" android:keyLabel="0" />

<Key android:codes="-3" android:keyLabel="收起" />

</Row>

</Keyboard>

3.代码中初始化键盘

private void initKeyboard() {

mKeyboardView.setKeyboard(new Keyboard(this, R.xml.keyboard_number));

mKeyboardView.setEnabled(true);

mKeyboardView.setPreviewEnabled(true);

mKeyboardView.setOnKeyboardActionListener(new KeyboardView.OnKeyboardActionListener() {

@Override

public void onKey(int primaryCode, int[] keyCodes) {

Editable editable = et.getText();//et为EditText

int start = et.getSelectionStart();

switch (primaryCode) {

case Keyboard.KEYCODE_DELETE:

if (editable != null && editable.length() > 0) {

if (start > 0) {

editable.delete(start - 1, start);

}

}

break;

case Keyboard.KEYCODE_DONE:

hideKeyboard();

Toast.makeText(NumberboardActivity.this,"买入",Toast.LENGTH_SHORT).show();

break;

case Keyboard.KEYCODE_CANCEL:

hideKeyboard();

break;

default:

String str = Character.toString((char) primaryCode);

editable.insert(start, str);

break;

}

}

public void onPress(int primaryCode) {

}

public void onRelease(int primaryCode) {

}

public void onText(CharSequence text) {

}

public void swipeDown() {

}

public void swipeLeft() {

}

public void swipeRight() {

}

public void swipeUp() {

}

});

}

4. 提供键盘隐藏显示方法，EditText调用

private void hideKeyboard() {

int visibility = mKeyboardView.getVisibility();

if (visibility == View.VISIBLE) {

mKeyboardView.setVisibility(View.GONE);

}

}

private void showKeyboard() {

int visibility = mKeyboardView.getVisibility();

if (visibility == View.GONE || visibility == View.INVISIBLE) {

mKeyboardView.setVisibility(View.VISIBLE);

}

}

...

et.setOnClickListener(new View.OnClickListener() {

public void onClick(View arg0) {

showKeyboard();

}

});

...
