Android 自定义 省份、车牌号键盘。

1.配省份、车牌号kebord数据源。

首先在资源目录res文件夹下创建xml文件夹。

明明省份数据源：

number_or_letters.xml:

接下来，在drawable 目录下定义按键背景：

click_key_bg.xml：

<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android" >   <corners android:radius="5dp"/>  <solid android:color="@color/color_first_green" />         </shape>

did_not_click_key_bg.xml：

<?xml version="1.0" encoding="utf-8"?><shape xmlns:android="http://schemas.android.com/apk/res/android" >   <corners android:radius="5dp"/>  <solid android:color="#ffffff" />         </shape>

----------关键部分：Z

界面部分

前面的准备工作做好，之后就将他们组合起来，下面看操作：

private Keyboard_Util keyboardUtil;

private EditText et_searchtxt;

注意，这里要绑定EditText来使用。

et_searchtxt = (EditText) findViewById(R.id.et_searchtxt);

et_searchtxt.setOnTouchListener(new View.OnTouchListener() {    @Override    public boolean onTouch(View view, MotionEvent event) {        rl_search.setVisibility(View.VISIBLE);        if(keyboardUtil == null){            keyboardUtil = new Keyboard_Util(Search_Activity.this, et_searchtxt);            keyboardUtil.hideSoftInputMethod();            keyboardUtil.showKeyboard();        }else {            keyboardUtil.showKeyboard();        }        return false;    }});et_searchtxt.addTextChangedListener(new TextWatcher(){    @Override    public void afterTextChanged(Editable s) {        Log.e("字符变换后", "afterTextChanged");    }    @Override    public void beforeTextChanged(CharSequence s, int start, int count, int after) {        Log.e("字符变换前",  s + "-" + start + "-" + count + "-" + after);    }    @Override    public void onTextChanged(CharSequence s, int start, int before, int count) {        Log.e("字符变换中", s + "-" + "-" + start + "-" + before + "-" + count);    }});

到这里就完成了。不懂的随时可以咨询和留言。
