android - Android Sqlite BaseAdapter 搜索视图和列表错误一致
问题描述
我正在尝试显示显示数据库值的列表视图，并且需要搜索这些项目，当单击它时获取该列表项目数据库 ID。我尝试了这段代码，但我的应用程序崩溃了。
我的数据库
这是我的数据库类，它从数据库中获取结果
package com.me.doctor.doctor_me;
import android.content.Context;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteQueryBuilder;
import com.readystatesoftware.sqliteasset.SQLiteAssetHelper;
public class DatabaseOperation extends SQLiteAssetHelper {
public static final int DB_VERSION = 1;
public static final String DB_NAME= "app_db.db";
public DatabaseOperation(Context context) {
super(context, DB_NAME,null, DB_VERSION);
}
// Verify user Loggin
public boolean loginUser(String email, String password) {
SQLiteDatabase db = this.getReadableDatabase();
SQLiteQueryBuilder qb = new SQLiteQueryBuilder();
String sqlTables = "user";
qb.setTables(sqlTables);
Cursor c = qb.query(db,null,"email = ? AND password = ?",new String[]{email,password},null,null,null);
if (c.getCount() > 0) {
return true;
} else {
return false;
}
}
//RETRIEVE DATA AND FILTER
public Cursor retrieve(String searchTerm)
{
SQLiteDatabase db = getReadableDatabase();
String[] columns = {"d_id","d_name","d_gender","d_hospital","d_category"};
Cursor c=null;
if(searchTerm != null && searchTerm.length()>0)
{
String sql="SELECT * FROM doctor WHERE d_name LIKE '%"+searchTerm+"%'";
c=db.rawQuery(sql,null);
return c;
}
c=db.query("doctor",columns,null,null,null,null,null);
return c;
}
}
这是我的医生课
package com.me.doctor.doctor_me;
public class Doctor {
int id;
String name, category, gender, hospital;
public Doctor(int id, String name, String category, String gender, String hospital) {
this.id = id;
this.name = name;
this.category = category;
this.gender = gender;
this.hospital = hospital;
}
public Doctor(){
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getCategory() {
return category;
}
public void setCategory(String category) {
this.category = category;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public String getHospital() {
return hospital;
}
public void setHospital(String hospital) {
this.hospital = hospital;
}
}
这是我的自定义数组适配器类
package com.me.doctor.doctor_me;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;
import android.widget.Toast;
import java.util.ArrayList;
public class CustomAdapter extends BaseAdapter {
Context c;
ArrayList<Doctor> doctors;
LayoutInflater inflater;
public CustomAdapter(Context c, ArrayList<Doctor> doctors) {
this.c = c;
this.doctors = doctors;
}
@Override
public int getCount() {
return doctors.size();
}
@Override
public Object getItem(int i) {
return doctors.get(i);
}
@Override
public long getItemId(int i) {
return i;
}
@Override
public View getView(int i, View view, ViewGroup viewGroup) {
if(inflater==null)
{
inflater= (LayoutInflater) c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
if(view==null)
{
view=inflater.inflate(R.layout.layout_item,viewGroup,false);
}
TextView nameTxt= view.findViewById(R.id.list_name);
nameTxt.setText(doctors.get(i).getName());
final int pos=i;
view.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(c,doctors.get(pos).getId(),Toast.LENGTH_SHORT).show();
}
});
return view;
}
}
这是我的控制器类
package com.me.doctor.doctor_me;
import android.database.Cursor;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.SearchView;
import android.support.v7.widget.Toolbar;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;
import java.util.ArrayList;
public class SearchActivity extends AppCompatActivity {
ListView lv;
SearchView sv;
EditText nameEditText;
Button retrieveBtn;
CustomAdapter adapter;
ArrayList<Doctor> doctors=new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
lv = findViewById(R.id.lv);
sv = findViewById(R.id.search_view);
adapter = new CustomAdapter(this, doctors);
sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
return false;
}
@Override
public boolean onQueryTextChange(String newText) {
getDoctors(newText);
return false;
}
});
}
private void getDoctors(String searchTerm)
{
doctors.clear();
DatabaseOperation databaseOperation = new DatabaseOperation(this);
Doctor d = null;
Cursor c = databaseOperation.retrieve(searchTerm);
while (c.moveToNext())
{
int id = c.getInt(0);
String name=c.getString(1);
String gender=c.getString(2);
String hospital=c.getString(3);
String category=c.getString(4);
d =new Doctor();
d.setId(id);
d.setName(name);
d.setGender(gender);
d.setCategory(category);
d.setHospital(hospital);
doctors.add(d);
}
lv.setAdapter(adapter);
}
}
这是我的布局文件
由自定义适配器膨胀的 layout_item.xml
