Android 自定義 省份、車牌號鍵盤。

1.配省份、車牌號kebord數據源。

首先在資源目錄res文件夾下創建xml文件夾。

明明省份數據源：

接下來，在drawable 目錄下定義按鍵背景：

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" />

前面的準備工作做好，之後就將他們組合起來，下面看操作：

private Keyboard_Util keyboardUtil;

private EditText et_searchtxt;

注意，這裏要綁定EditText來使用。

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("字符變換後", "afterTextChanged");
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        Log.e("字符變換前",  s + "-" + start + "-" + count + "-" + after);

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        Log.e("字符變換中", s + "-" + "-" + start + "-" + before + "-" + count);



    }
});

到這裏就完成了。不懂的隨時可以諮詢和留言。
