在Android的一个particularword服用后弦 [英] taking string after a particularword in android

问题描述

我的问题是，我必须添加一个搜索 建议在我的应用程序。它应该像这样工作：

如果用户写道：@  比搜索框将显示contacts.and如果没有接触比将@共享preferences后的字存储。如果用户presses＃比它应该表现出的哈希标签，如果它存在于我的平方精简版。如果不是在分贝它将本身存储在分贝

  subjectEditText.addTextChangedListener（新TextWatcher（）{
    @覆盖
    公共无效beforeTextChanged（CharSequence中，诠释开始，诠释计数，之后INT）{

    }

    @覆盖
    公共无效onTextChanged（CharSequence中，诠释开始，诠释之前，诠释计数）{

        模式p = Pattern.compile（（＃））;
        p .compile（（@））;
        匹配M = p.matcher（subjectEditText.getText（）的toString（））;
        而（m.find（））{
            Toast.makeText（Addhash.this，发现，Toast.LENGTH_SHORT）.show（）;

        }
    }

    @覆盖
    公共无效afterTextChanged（编辑S）{

}）;
 

解决方案

你应该使用onkey preSS听者和及赤关键preSS如果preSS @那么做你想要它了Java然后一路权的furthor code就可以解决您的ID

my problem is i have to add a search suggestion in my app. It is Supposed to work like this:

if user writes "@" than the search box will show contacts.and if there is no contacts than it will store in the word after "@" shared preferences. if user presses "#" than it is supposed to show hash tags if it exists in my sq lite. and if not in db it will store itself in db.

subjectEditText.addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {

        Pattern p = Pattern.compile("(#)");
        p .compile("(@)");
        Matcher m = p.matcher(subjectEditText.getText().toString());
        while (m.find()){
            Toast.makeText(Addhash.this,"find",Toast.LENGTH_SHORT).show();

        }
    }

    @Override
    public void afterTextChanged(Editable s) {

    }
});

解决方案
