android ListView 过滤器 - 空格字符 [英] Filter for android ListView - Space Character

问题描述

我想使用 EditText 框和适配器 getFilter() 函数过滤我的 listView.它工作得很好，直到我在文本框中放置一个空格字符.

这是一个 SimpleAdapter 而不是 ArrayAdapter

如果我的列表包含这些词:{Apple"、Banana"、Red Apple"}如果我输入apple"，它将返回所有包含单词 apple 的项目(Apple 和 Red Apple).如果我输入apple"，它不会返回任何东西.

有什么想法吗?代码如下:

searchBox = (EditText) findViewById(R.id.searchBox);searchBox.addTextChangedListener(filterTextWatcher);

和

private TextWatcher filterTextWatcher = new TextWatcher() {public void onTextChanged(CharSequence s, int start, int before, int count) {//TODO 自动生成的方法存根}public void beforeTextChanged(CharSequence s, int start, int count,输入后) {//TODO 自动生成的方法存根}公共无效 afterTextChanged(可编辑的){//TODO 自动生成的方法存根myAdapter.getFilter().filter(s.toString());}};

解决方案

如果 SimpleAdapter 的过滤功能不能满足您的过滤要求，您将需要覆盖 SimpleAdapter 并实现您自己的过滤要求.

这需要大量代码，因为SimpleAdapter 中的过滤器使用了大量私有对象，您需要复制这些对象.ArrayAdapter

同样适用

幸运的是，其他人 (@uʍop ǝpısdn) 已经参与了该流程，编写了代码并将其提供给社区.

您可以在此处找到博客链接，包括如何使用示例，以及 here 中的代码.

问候.

I want to filter my listView using an EditText box and using the adapter getFilter() function. It works just fine until I put a space character in the text box.

Edit: It's a SimpleAdapter not ArrayAdapter

If my list contains these words: {"Apple", "Banana", "Red Apple"} If I type "apple" it will return all the items containing the word apple in it (Apple and Red Apple). If I type "apple " it won't returning anything.

Any ideas? Here's the code:

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

searchBox.addTextChangedListener(filterTextWatcher);

and

private TextWatcher filterTextWatcher = new TextWatcher() {

public void onTextChanged(CharSequence s, int start, int before, int count) {
    // TODO Auto-generated method stub          
}

public void beforeTextChanged(CharSequence s, int start, int count,
            int after) {
    // TODO Auto-generated method stub          
}

public void afterTextChanged(Editable s) {
    // TODO Auto-generated method stub
    myAdapter.getFilter().filter(s.toString());
}
};

解决方案

If the filtering functionality from SimpleAdapter doesn't fulfill your filtering requirements, you will need to override the SimpleAdapter and implement your own filtering requirements.

This requires a lot of code, as Filter in SimpleAdapter is using a lot of private objects, that you will need to replicate. The same aplies for ArrayAdapter

Fortunatly, someone else (@uʍop ǝpısdn) already went to the process, wrote the code and made it available for the community.
