Question

我正在尝试在android中实现搜索功能来搜索按钮。通常，搜索用于搜索listviews，但我想用它来搜索按钮。我的活动中有118个按钮，顶部有一个edittext（搜索栏）。每个按钮代表化学元素的符号例如：
铜=铜
Zn =锌
O =氧气
F =氟 Cl =氯
还有112个....

这就是我的活动的样子（此屏幕截图只是为了更好地解释我的问题，而不是实际活动）

这张图片只显示了6个按钮，但我还有112个按钮。搜索栏看起来一样
现在，这就是我想要实现的目标。

我想立即突出显示代表键入元素的按钮。用户将键入元素的名称，但应突出显示代表其符号的按钮。我怎样才能做到这一点？

我了解了TextWatchers()以及使用它们搜索列表视图的方式：

searchbar.addTextChangedListener(new TextWatcher() {

@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
    // When user changed the Text
    MainActivity.this.listviewadapter.getFilter().filter(cs);   
}

@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
        int arg3) {
    // TODO Auto-generated method stub

}

@Override
public void afterTextChanged(Editable arg0) {
    // TODO Auto-generated method stub                          
}
});

以下是上述屏幕截图的xml。

<RelativeLayout

这是包含所有化学元素名称的数组：

请帮我实现搜索按钮搜索！
谢谢你的时间！

Answer 1

创建一个函数doSearchAction，如下所述：

//执行搜索操作需要在onSearch事件上调用，即搜索栏文本观察器。

private void doSearchAction(List<Button> btnList)
        {
          resetAllButton();
        for(int i=0;i<btnList.size;i++)
        {
        Button btn = btnList.get(i);
        btn.setBackgroundResource(R.drawable.highlight_img); 
        }

//将所有按钮重置为默认的drawables

   private void resetAllButton()
        {
    // reset all button to default value    
    btn1.setBackgroundResource(R.drwable.normal_img)
    ....

    all_buttons.setBackgroundResource(R.drwable.normal_img)


        }

突出显示搜索按钮
