问题描述

如何触摸如图图像右侧字母面板上的字母时,增加testview? 请你帮助我好吗?下面是我的code。

在细节,我正在寻找一个完全像下面的图像的例子。目前,我没有数据的排序。当我点击右侧的字母面板上显示数据正常。但问题是触摸字母右边的字母板,我需要证明什么信他是pressing在图像(E)显示大尺寸的时候。我该怎么办呢,你能帮帮我吗?预先感谢您!

解决方案

听到的是你所需要的 HTTPS一个凉爽的例子://github.com/woozzu/IndexableListView

为了编译项目,并摆脱韩国文字更新 StringMatcher

 包com.woozzu.android.util;

公共类StringMatcher {
    公共静态布尔匹配(字符串值,字符串关键字){
        如果(价值== NULL ||关键字== NULL)
            返回false;
        如果(keyword.length()> value.length())
            返回false;

        INT I = 0,J = 0;
        做 {
            INT六= value.charAt(ⅰ);
            INT KJ = keyword.charAt(J);
            如果(isKorean(ⅵ)&安培;&安培; isInitialSound(KJ)){
            } 其他 {
                如果(六== KJ){
                    我++;
                    J ++;
                }否则如果(J&0)
                    打破;
                其他
                    我++;
            }
        }而(ⅰ&其中; value.length()&安培;&安培; J&其中; keyword.length());

        返程(j == keyword.length())?真假;
    }

    私有静态布尔isKorean(int i)以{
        返回false;
    }

    私有静态布尔isInitialSound(int i)以{
        返回false;
    }

解决方案

Hear is one cool example of what you need https://github.com/woozzu/IndexableListView

IN order to compile the project and get rid of korean text update the StringMatcher class

package com.woozzu.android.util;

public class StringMatcher {
    public static boolean match(String value, String keyword) {
        if (value == null || keyword == null)
            return false;
        if (keyword.length() > value.length())
            return false;

        int i = 0, j = 0;
        do {
            int vi = value.charAt(i);
            int kj = keyword.charAt(j);
            if (isKorean(vi) && isInitialSound(kj)) {
            } else {
                if (vi == kj) {
                    i++;
                    j++;
                } else if (j > 0)
                    break;
                else
                    i++;
            }
        } while (i < value.length() && j < keyword.length());

        return (j == keyword.length())? true : false;
    }

    private static boolean isKorean(int i) {
        return false;
    }

    private static boolean isInitialSound(int i) {
        return false;
    }
}
