我正在开发一款Android应用，它可以从谷歌电子表格中获取信息并输入列表视图。但是，我无法为此提出解决方案。 任何帮助将不胜感激。 对于电子表格集成，我使用Google表格API。 我知道客户端登录不安全，但这只是一个用于项目目的的测试应用程序：）
以下是我的代码 -
package com.bish.test;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import android.widget.Toast;
import android.app.Activity;
import android.app.ProgressDialog;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.GridView;
import android.widget.ListView;
import android.widget.Toast;
import com.google.gdata.client.authn.oauth.*;
import com.google.gdata.client.spreadsheet.*;
import com.google.gdata.data.*;
import com.google.gdata.data.batch.*;

import com.google.gdata.util.*;
import java.io.IOException;

import java.util.*;
public class MainActivity extends ActionBarActivity {
SpreadsheetService service = new SpreadsheetService("MySpreadsheetIntegration-v1");
String USERNAME = "cccc@gmail.com";
String PASSWORD = "xxx";
ListView list;
String[] web;
Integer[] imageId;
CustomList adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
logIn();
try {
refreshData();
} catch (IOException e) {
e.printStackTrace();
} catch (ServiceException e) {
e.printStackTrace();
}
adapter = new CustomList(MainActivity.this, web, imageId);
list=(ListView)findViewById(R.id.list);
list.setAdapter(adapter);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.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();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public void logIn()
{
final ProgressDialog ringProgressDialog = ProgressDialog.show(MainActivity.this, "Please wait ...", "Logging In...", true);
ringProgressDialog.setCancelable(true);
new Thread(new Runnable() {
@Override
public void run() {
try {
service.setUserCredentials(USERNAME, PASSWORD);
Thread.sleep(2200);
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "ERROR: Check your Internet Connection!", Toast.LENGTH_LONG).show();
e.printStackTrace();
System.exit(0);
}
ringProgressDialog.dismiss();
}
}).start();
}
public void refreshData() throws AuthenticationException, MalformedURLException, IOException, ServiceException
{
}
}
答案 0 :(得分：0)
我希望这会对你有所帮助。 这段代码：
1）创建一个新的电子表格
2）插入新的工作表
3）在单元格中插入一些值
4）显示单元格中的值
