今天完成的是带历史记录的搜索框
利用的是一个集成好的框架，一个带历史记录的框架。首先在主界面设置一个搜索的按钮，点击后来到全局搜索的布局页面，然后输入搜索的关键字， 点击搜索就会出现对应的文章，点击任意文章后就会看到相应的博文。
SearchActivity
package com.example.newbsh.UI.Find;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import scut.carson_ho.searchview.ICallBack;
import scut.carson_ho.searchview.SearchView;
import scut.carson_ho.searchview.bCallBack;
import com.example.newbsh.R;
public class SearchActivity extends AppCompatActivity {
private SearchView searchView;
public static String text;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search);
// 3. 绑定组件
searchView = (SearchView) findViewById(R.id.search_view);
// 4. 设置点击搜索按键后的操作（通过回调接口）
// 参数 = 搜索框输入的内容
searchView.setOnClickSearch(new ICallBack() {
@Override
public void SearchAciton(String string) {
text=string;
Intent intent=new Intent(SearchActivity.this,FindActivity.class);
startActivity(intent);
//finish();
}
});
// 5. 设置点击返回按键后的操作（通过回调接口）
searchView.setOnClickBack(new bCallBack() {
@Override
public void BackAciton() {
finish();
}
});
}
public static String getText() {
return text;
}
}
