系统自带的键盘,键值太多,不符合客户的需求,需要自定义键盘,如下图:
分别是字母和数字的键盘,感谢很多前辈提供的例子,朋友们可以到这个链接下载资源:前辈android 自定义键盘详解讲的非常清楚,我下了他的代码,在这基础上进行修改,遇到的第一个问题就是第一个图上的: “ .?&” ,如何在键盘上显示这样的文本,假设采用楼主设置文本的形式进行设置的时候,会遇到如下错误:
The entity name must immediately follow the ‘&’ in the entity reference
这个错误的解决方案是:
主要是xml无法解析 && 这样一个逻辑符号。所以要将他写出
2.好,接着第二个问题:其他特殊符合如“,”之类的都可以使用转义字符,但遇到“@”,你就不能好好的使用转义字符来解决了:
上述代码同样会报一个这样的错误:error: Error: No resource type
specified (at 'keyLabel' with value '@').万能的百度也没有搜到解决方
案,我就很奇怪,不是已经转义了吗?怎么还是识别不了呢,后来想想是不是xml
文件会不会认为@后面还得跟个什么东西,所以这样写就是有错的,那好我就再用
如下语句:“\”来进行转义,应该就可以了,我修改成如下的代码,保存,运行
没有出错了。
注意:如果你使用到图片的话,@drawable/delete这样的时候,也需要将@进行转义,这个问题的确很奇怪,我在另外一个xml文件直接使用是没有问题的,不知道是什么原因,大神如果知道的话,麻烦告诉一声。
3.第三个问题:遇到键盘上要显示反斜杠,也就是“\”的时候,因为\是起转义
字符的作用,所以要显示\,需要再进行转义一次,也就是如下语句:
4.在设置了edittext之后,要隐藏系统的软键盘,这时候就会遇到奇怪的问
题,光标消失了并且没有闪烁,所以百度了一下,将edittext传入到函数里面
,然后就可以使用如下方法,就可以使光标出现:
edit = (EditText) this.findViewById(R.id.edit);
// edit.setInputType(InputType.TYPE_NULL);
hideSoftInputMethod(edit);
// 隐藏系统键盘
public void hideSoftInputMethod(EditText ed) {
getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
int currentVersion = android.os.Build.VERSION.SDK_INT;
String methodName = null;
if (currentVersion >= 16) {
// 4.2
methodName = "setShowSoftInputOnFocus";
} else if (currentVersion >= 14) {
// 4.0
methodName = "setSoftInputShownOnFocus";
}
if (methodName == null) {
ed.setInputType(InputType.TYPE_NULL);
} else {
Class cls = EditText.class;
Method setShowSoftInputOnFocus;
try {
setShowSoftInputOnFocus = cls.getMethod(methodName,
boolean.class);
setShowSoftInputOnFocus.setAccessible(true);
setShowSoftInputOnFocus.invoke(ed, false);
} catch (NoSuchMethodException e) {
ed.setInputType(InputType.TYPE_NULL);
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InvocationTargetException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
5.如果你有如下的需求:在点击界面上任何一个edittext,弹出自定义键盘还
有一个按钮,用来隐藏自定义键盘,如下图:
也就是点击隐藏的图标,隐藏掉自定义键盘,这个需求其实蛮简单的:就是需要
给显示键盘的布局一个id,当点击隐藏按钮之后,将布局Visibility的属性设置
为Gone或者InVisibility,其中gone表示不占空间和内存。示例如下(部分代
码:
private RelativeLayout relakey;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ctx = this;
act = this;
relakey = (RelativeLayout) this.findViewById(R.id.relakey);
hideshow = (TextView) this.findViewById(R.id.hideshow);
hideshow.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
relakey.setVisibility(View.GONE);
}
});
edit = (EditText) this.findViewById(R.id.edit);
// edit.setInputType(InputType.TYPE_NULL);
hideSoftInputMethod(edit);
edit.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
relakey.setVisibility(View.VISIBLE);
hideshow.setVisibility(View.VISIBLE);
new KeyboardUtil(act, ctx, edit).showKeyboard();
return false;
}
});
6.其他的问题如给key按键设置自己的图片,我会遇到莫名其妙的问题,就是图片太大,把键盘挤出去了,而我使用系统默认的比如删除、切换大小写之类的图片就不会出现这样的问题,期待大神给予帮助,目前为止还未解决。
7.最后一个问题,如果看过这篇博文的人,android 自定义键盘(前辈)应该都知道如果要自定义键盘的话,需要重写里面的键盘布局xml文件,其实是很简单,就是一行一行的进行配置即可,下面对于一些属性我加上自己的使用经验和理解,希望给菜鸟一些帮助。
下面是各个属性的解释:
(1)android:keyWidth="9.55%p":该属性表示每个键盘上的单个按键占据的宽度百分比,举个例子是:键盘总共有3行,每行有10个的话,那么每个按键就是
10%。
(2)android:keyHeight="@dimen/key_height2":该属性用来设置每个单个按键所占的高度,具体的就不细说了,可以用dimen进行灵活配置。
(3)android:horizontalGap="1px" android:verticalGap="3px":这两个属性表示:每个按键之间在水平和竖直方向的间距,为了美观,该属性是必须设置的否则你会发现你的键盘丑死了,都挤到一块去了。
(4)android:keyEdgeFlags="left":表示对于整个键盘这一行来说,这个按键是居于最左边的,也可以设置成最右边,这个属性我发现如果不设置的话,也不影响键盘的正常显示。
(5android:keyLabel="3":该属性表示按键显示的文本,可以随意填,但如果碰到一些xml文件中不能直接显示的字符如&、@、‘等需要转义,如何转义可以参考上面的第一条建议。
(6)android:codes="48":这个对于该自定义键盘来说是非常重要的一个属表示对于一些数字、字母、标点符号等所有能在键盘找到的,必须用ascii码来对应,对于这些char字符对应的ascii的对应关系,好吧,我就告诉你们,链接如下:ascii码转换表ascii转换对应表当然了,如果想输入一些奇怪的东西,建议你的codes值不要与ascii码相同,可以取得很大,就不会有冲突了。
(7)android:keyIcon="@drawable/sym_keyboard_shift":该属性表示对于该按键,你可以自定义自己的图片放上去。
(8)android:isRepeatable="true":表示对于该按键长按是否会连续输入,这个属性对于删除键来说极其有效。
如果你用心的阅读完上述的内容,你肯定也可以设计出自己的自定义键盘,有问题随时与我交流,可以在下方评论,我会及时给与解答。
真的要放大福利了,我的android 自定义键盘(包含字母、标点符号)的完善版本已经上传到csdn,链接如下:android 自定义键盘 (nihaoqiulinhe所有)

当输入自定义的键盘上的数字时,比如说如果是300000,有这样一个需求,当点击300000时,要清除掉之前的数据,切换时也需要清除掉,如下键盘代码:
