我已经成功创建了一个Xml Parser，它在TextView中输出整个Xml。但是我找不到用户输入搜索的方法，因此可以在TextView中输出答案之前搜索Xml的输入。有人可以帮忙吗？
public void Species() {
Common = "Not set";
Latin = "Not set";
Where = "Not set";
Kingdom = "Not set";
Phylum = "Not set";
Class = "Not set";
Order = "Not set";
Family = "Not set";
Genus = "Not set";
Scientific = "Not set";
}

setContentView(R.layout.activity_main);
button = (Button) findViewById(R.id.button);
button.setOnClickListener(this);

search.setOnClickListener(this);
