先修改Book.java文件import org.litepal.crud.DataSupport;
/**
* Created by xinwei on 2017/10/21.
*/
public class Book extends DataSupport{
private int id;
private String anthor;
private double price;
private int pages;
private String name;
private String press;
public String getPress() {
return press;
}
public void setPress(String press) {
this.press = press;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getAnthor() {
return anthor;
}
public void setAnthor(String anthor) {
this.anthor = anthor;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
public int getPages() {
return pages;
}
public void setPages(int pages) {
this.pages = pages;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
修改mainactivity.java文件package com.example.xinwei.mylitepal;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import org.litepal.tablemanager.Connector;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button createDatabase = (Button)findViewById(R.id.create_database);
createDatabase.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Connector.getDatabase();
}
});
addData();
}
private void addData() {
Button addData = (Button)findViewById(R.id.add_data);
addData.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Book book = new Book();
book.setName("The Da Vinci Code");
book.setAnthor("Dan Brown");
book.setPages(454);
book.setPrice(16.96);
book.setPress("Unknow");
book.save();
}
});
}
}
其中addData()方法里就是添加数据的方法 |
