我是Android工作室的新手，请给我下面给出的代码解决方案，现在我想以列表形式在SearchView下方显示我的结果，它应该是可点击的
这是我的Main_Activity.java代码
package com.example.jawa.pos;
import android.app.Activity;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageButton;
import android.widget.Toast;
/**

*/
public class AddNewUser extends Activity {
DATA_BASE data_base;
EditText accountnumber,personalname,email,phonenmber,comment;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.addnewuser);
data_base= new DATA_BASE(this);
accountnumber = (EditText) findViewById(R.id.accountnumber);
personalname = (EditText) findViewById(R.id.customernumber);
phonenmber = (EditText) findViewById(R.id.phonenumber);
email = (EditText) findViewById(R.id.email);
comment= (EditText) findViewById(R.id.comment);
}
public void register(View view) {
int Accountnumber = Integer.parseInt(accountnumber.getText().toString());
String Personalname = personalname.getText().toString();
int Phonenumber = Integer.parseInt(phonenmber.getText().toString());
String Email = email.getText().toString();
String Comment = comment.getText().toString();
//Add some Customer data as a sample
long id = data_base.createCustomer(Accountnumber, Personalname, Phonenumber, Email, Comment);
if(id <0){
Toast.makeText(this,"Unsuccessful",Toast.LENGTH_SHORT).show();
}else {
Toast.makeText(this,"Successful",Toast.LENGTH_SHORT).show();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
这是我的DATA_BASE_Adapter.java文件

现在我想通过适配器将SearchView提供给此数据库，并且此reslut应显示在Listview中。
请有人帮帮我 从最近两周尝试破解，但无法找到解决方案。
